Those who do not try to hack the Cybook Odyssey e-reader won't understand the title. In facts, Bookeen appends this sentence at the end of update files. Arrogant, isn't it ? Surely, but now it's outdated.

Bookeen primary delivers a full access to its e-readers. Unfortunately, since Odyssey one they became very proprietary while its concurrents (except Amazon) lets user modify the core system. Did the concurrents puts out of business ? No. They're still alive, and they sell more e-readers than Bookeen. Kobo ahead.

OK, stop doing politic and start hacking. It has been a hard work, but I finally did it : a Cybook Jailbreak.

This jailbreak installs dropbear (a SSH client/server) onto the e-reader and launch it at boot. It has been fully tested on Cybook Odyssey and Nolimbook HD+ (Muse) whatever the firmware version running. See notes for other Cybook versions.

ADB

I Finally found how to activate adb daemon on AW8/13 platforms (all platforms except Odyssey one). It's less destructive than apply a new update. To do it, follow these instructions :

  • Plug your reader in USB mode
  • Create an empty file called "adb_debug" in the mounted filesystem
  • Unplug your reader
  • Plug your reader in USB mode again
  • A popup should appears asking you if you want your computer to see your reader's files : SAY NO
  • Go to Menu -> Advanced
  • Click on "Open ADB"

Now you should be able to use adb util to open a shell on your reader. I can't start adb on my Odyssey reader, maybe you should enable ADB first and plug your reader after or use adb through Wifi.

Downloads

It seems that more and more people have problems with these jailbreaks for Nolimbook device. So, please, don't try it if your current reader has a different version than the proposed one. Plus, Bookeen don't seems to upload new firmwares (they're only burned in factory). For now (as I don't own a Muse serie device), I can't provide another way to jailbreak it.

Muse firmware should be compatible with Odyssey frontlight 2

Signature verification

gpg --verify SHA256SUMS.sign SHA256SUMS

My gpg key can be found here

Instructions

Rename downloaded files into CybUpdate.bin and copy it to the e-reader via USB. De-connect USB and start upgrade.

Once rebooted, activate Wifi and connect to the e-reader (you can find the IP address in your internet box/router web interface) :

ssh -o "KexAlgorithms +diffie-hellman-group1-sha1" -o "Ciphers +aes128-cbc" root@EREADERIP

There is no password.

Those who uses Windows can download putty as SSH client.

Info : I compiled a new version of dropbear, but I'm not able to test it. If someone want to test, send me an email. I will then put it on new jailbreak versions.

Enjoy !

Tip : The e-reader goes to sleep after X minutes of inactivity and switch off Wifi, and thus SSH connexion. To avoid this problem, kill ebrmain and boordr (the first re spawn the second).

Notes for Muse/Nolimbook/Odyssey essential/Odyssey frontlight 2 e-readers

The update format has changed and for my surprise it's more simple than the previous one. I saw that the whole flash is overwritten during an update. So, keep the jailbreak related to your current version.

If you want to make your own custom ROM, please read my another article How to make custom ROM for Cybook e-readers

Nolimbook recover

A lot of people bricked their reader after applying jailbreak on Carrefour Nolimbook device. KotCzarny succeded in recover its reader by reading NAND flash thanks to UART pads available on motherboard. Here is a stock ROM 5.2.2020. Thanks to him ! For any more help, he is reachable on freenode irc, channel #h3droid, nick KotCzarny.

A page dedicated to Muse device has been created on linux-sunxi. You'll find some information about Muse hardware and FEL mode (in an other section). On new hardware boards, there is no information printed about UART pins, you needs to search dedicated pins thanks to a multimeter. Don't hesitate to update the page with new information !

Backup for Odyssey

Hacking Odyssey may lead to editing/removing files you should not. A backup jailbreak that contains a full factory image (+SSH server) is available for Odyssey readers. It willl only works if /boot has not been damaged !!

Hacking Muse

Alejandro Antúnez hacks basic display/event functions in combination with DirectFB, helping develop applications. Code and example are available on GitHub. A lot of thanks to him.

Legal notices

Providing a jailbreak is not a benign choice. I had a long reflexion before this and tried to know why Bookeen doesn't wants users access core system. The only response I got was "It's not scheduled".

Laws concerning copyright are complex and different in each country. France has its own who is called DADVSI (Loi relative au droit d'auteur et aux droits voisins dans la société de l'information) which is the transposition of European directives. It defines DRM and penal sentences. We can resume in some paragraphs (sorry, french only) :

Article 13

« Art. L. 331-5. - Les mesures techniques efficaces destinées à empêcher ou à limiter les utilisations non autorisées par les titulaires d'un droit d'auteur ou d'un droit voisin du droit d'auteur d'une oeuvre, autre qu'un logiciel, d'une interprétation, d'un phonogramme, d'un vidéogramme ou d'un programme sont protégées dans les conditions prévues au présent titre.

« On entend par mesure technique au sens du premier alinéa toute technologie, dispositif, composant qui, dans le cadre normal de son fonctionnement, accomplit la fonction prévue par cet alinéa. Ces mesures techniques sont réputées efficaces lorsqu'une utilisation visée au même alinéa est contrôlée par les titulaires de droits grâce à l'application d'un code d'accès, d'un procédé de protection tel que le cryptage, le brouillage ou toute autre transformation de l'objet de la protection ou d'un mécanisme de contrôle de la copie qui atteint cet objectif de protection.

Un protocole, un format, une méthode de cryptage, de brouillage ou de transformation ne constitue pas en tant que tel une mesure technique au sens du présent article.

« Les mesures techniques ne doivent pas avoir pour effet d'empêcher la mise en oeuvre effective de l'interopérabilité, dans le respect du droit d'auteur. Les fournisseurs de mesures techniques donnent l'accès aux informations essentielles à l'interopérabilité dans les conditions définies aux articles L. 331-6 et L. 331-7.

« Les mesures techniques ne peuvent s'opposer au libre usage de l'oeuvre ou de l'objet protégé dans les limites des droits prévus par le présent code, ainsi que de ceux accordés par les détenteurs de droits.

Article 14

« Art. L. 331-7. - Tout éditeur de logiciel, tout fabricant de système technique et tout exploitant de service peut, en cas de refus d'accès aux informations essentielles à l'interopérabilité, demander à l'Autorité de régulation des mesures techniques de garantir l'interopérabilité des systèmes et des services existants, dans le respect des droits des parties, et d'obtenir du titulaire des droits sur la mesure technique les informations essentielles à cette interopérabilité. A compter de sa saisine, l'autorité dispose d'un délai de deux mois pour rendre sa décision.

« On entend par informations essentielles à l'interopérabilité la documentation technique et les interfaces de programmation nécessaires pour permettre à un dispositif technique d'accéder, y compris dans un standard ouvert au sens de l'article 4 de la loi n° 2004-575 du 21 juin 2004 pour la confiance dans l'économie numérique, à une oeuvre ou à un objet protégé par une mesure technique et aux informations sous forme électronique jointes, dans le respect des conditions d'utilisation de l'oeuvre ou de l'objet protégé qui ont été définies à l'origine.

« L'autorité a le pouvoir d'infliger une sanction pécuniaire applicable soit en cas d'inexécution de ses injonctions, soit en cas de non-respect des engagements qu'elle a acceptés. Chaque sanction pécuniaire est proportionnée à l'importance du dommage causé aux intéressés, à la situation de l'organisme ou de l'entreprise sanctionné et à l'éventuelle réitération des pratiques contraires à l'interopérabilité. Elle est déterminée individuellement et de façon motivée. Son montant maximum s'élève à 5 % du montant du chiffre d'affaires mondial hors taxes le plus élevé réalisé au cours d'un des exercices clos depuis l'exercice précédant celui au cours duquel les pratiques contraires à l'interopérabilité ont été mises en oeuvre dans le cas d'une entreprise et à 1,5 million d'euros dans les autres cas.

Article 21

« Art. L. 335-2-1. - Est puni de trois ans d'emprisonnement et de 300 000 EUR d'amende le fait :

1° D'éditer, de mettre à la disposition du public ou de communiquer au public, sciemment et sous quelque forme que ce soit, un logiciel manifestement destiné à la mise à disposition du public non autorisée d'oeuvres ou d'objets protégés ;

I think it's a good summary. The purpose of this jailbreak is to fully access a computer I OWN without damage it. Particularly, it do not help to get/read illegal content.

Hello !

This looks very interesting ! Thanks a lot for creating this installer, I will try it as soon as I've upgraded to 6.2 :-)

Can you explain how it works and how you did ? Also, is there a place where I can find technical documentation about how the Cybook works ?

Thanks in advance :-)

You're welcome.

If you have a Cybook Odyssey, you can use it whatever the version installed.

This one uses update format to install dropbear (an SSH server). Unfortunately, there is absolutely no documentation about the Cybook. I had to do reverse engineering on update files and, for now, I'll not publish my sources for security reasons (I do not want someone to produce a binary with malware).

I don't think producing malwares for the Cybooks would be a good idea, as they are less often connected to the Internet and contains less personal data than a PC or a smartphone.

Anyway, I have some basic knowledge in system programming so I think I'll try to figure out how the upgrade mechanism works by myself :-)

I know, but until it's wide spread, I'll not publish my sources.

It's not important to understand how upgrade works. With SSH access you can develop applications and/or modify core system. I think it's more important to understand how to access FrameBuffer and create a library.

Do you have a special project using Cybook Odyssey ?

Thanks a lot for your work.
I've been waiting for this moment ...


Just tested the files on my nolimbook HD + (a rebranded cybook muse), and the update was correctly detected and installed on the first reboot.

Except that putty is unable to connect, giving a message : "Network error: Connection refused"
(while the tablet is connected to wifi and responds to ping packets)

any idea ?

Thanks a lot.

When you have to break a system, you must analyse all the things you have : source code, update files, software... You do a lot of hypothesis and try to verify them. It's a long work, because most of the time it failed. But, one day, it success :)

Like Bookeen's engineers, I work on embedded systems. So, I know some of weak points and try to break through them.

It doesn't break anything. At least it doesn't works. But, for odyseey readers there is no problems.

The update format only change for Muse/Nolimbook readers.

Nice work !!
Just tested the new cybook muse file (jailbreak_6_2_2317_cybft.bin) on the Nolimbook HD.

The installation/update seems to go fine, it took about 5 minutes to finish, the boot screen is now changed to "Cybook muse", the menus are unchanged, the home screen still shows a "nolim store" image, the tablet is still identified as a "Nolimbook HD" in the about menu, but the Boo Reader is now versioned as 6.3 build 2326 (it was an older version before this jailbreak)

As for the SSH server, I still get a "Connection refused" with putty when I try to connect to port 22 :( (I made sure to use a static ip, disabled the firewall, and tested with ping)

I tried a software reset, a 2nd installation of the jailbreak, but always same error.

I hope this will be resolved soon, as the hardest step is already done !

Finally!
Jailbreak is working with my Nolimbook HD+.
Have access into filesystem, can down- and (probably) upload (didn't try that yet) files onto internal filesystem.
Looking foreward to explore it farther, since Carrefour software version of this great device is very limited.
Thanks for that opportunity!

Don't waste your time trying to figure that out. There is a comment from Bookeen regarding the backlight intensity, stating that it is manufacture made and could only solved by the manufacturer.
http://blog.bookeen.com/fr/maj-muse-odyssey-6-3/

"1. les niveaux minimum / maximum de luminosité sont une fonction du matériel. Donc il n’est pas possible de les modifier par une mise à jour logiciel. Par contre, vous êtes plusieurs à nous avoir signalé la luminosité trop forte, nous travaillons donc à améliorer cela pour les prochaines productions des Muse."

This allowed me to get an english dictionary on my Letto Front Light (which is a rebranded Cybook Muse Frontlight, sold by a swedish book dealer called Adlibris).
For the fellow swedes that want a english dictionary instead of the stocked swedish one, this worked wonders. Just change the priority of the dictionaries so english one takes precedence over the english-to-french one.

Hello

Just a comment to tell you a great new: my own "nolim +hd" with it's infamous limitations, feels now like a brand new "cybook muse frontlight":
After hours of searching I discover the way this ebook setup itself with the nvram utility : nvram -s to read the serial, nvram -S "new-serial" to replace by a new one.

All I can tell you now, is that the old serial was starting by CF616; the new one is starting with bk646 wich seems to be the official realase of my eBook without "carrefour" limitations.

Please be advised you can brick your own eBook if store incorrect informations in nvram.
All I have done is setup the book to think it's a "genuine" version: the document https://fccid.io/document.php?id=2437244 tells us theses devices are the same thing with different names, color packaging...

before: http://i.imgur.com/Nd91i8H.jpg
after: http://i.imgur.com/lg9ez5D.jpg

Thanks to gregory's jailbreaker to permit me this thing.

One comment about changing the serial number, be careful, as just changing the two letter may create an existing serial number used on another device (it's unlikely but could happen) and in this case if they haven't changed their backend it could led to strange behaviour is some condition.

Also DO NOT CHANGE anything else than the first two letter or you may break things on your device (I know that some devices use the serial number to check if some functionality are available or not)

Hello,

I've just upgraded my nolim and now I have the new boo reader. Thanks a lot Greg!!

About the serial number, and lifting the carrefour limitations, is the trick only to replace the first 5 chars of the current serial. IE:
CF646WE1SE.... to BK646WE1SE?

Thx

perfectly:

the whole process to change a nolim to a muse is to change the first 5 characters from the serial:
here is what I'v done just right now on a fresh new one nolim:
1/ install the jailbreaker from Greg,
2/ login with putty :
login as: root
root@192.168.144.104's password:
# nvram -s
sn=CF616<the-end-of-your-serial>
# nvram -S BK646<the-end-of-your-serial>
## geek-mode: (select the end of your serial, then middle click to paste it after your BK464 prefix)
# nvram -s
sn=BK646<the-end-of-your-serial>
# reboot
3/ the connection will close , the device reboot , show you the banner from
cybook-muse, the software loaded is now clean and has for exemple, the option to browse directories in your library (that one was missing from the nolim brain damaged version)
4/ as a security, I've 'factory default'ed the eBook reader also (still rebooting as a cybook-muse)
5/ now you can also check for officials upgrades (connect to wifi and wait) of your cybook muse..

That's the third reader I un-downgrade this way. It's take less than 5 minutes..

Hi,

I just bought the Nolim+ HD plus in Spain and I would like to boost the firmware. Your tutorial is clear but I wonder why you changes CF616 to BK646. The S/N of my Nolim is CF646. Should I leave it like it is, or should I change it to BK616? I mean, why you replaces the 1 in CF S/N by the 4 in BK S/N?

Another question: "now you can also check for officials upgrades (connect to wifi and wait) of your cybook muse". Where you able to receive an official upgrade after the "un-downgrade"?


Thanks a lot in advance your help,

F.

Hi,

I was near to give up thinking that the Cybook is ever rooted and today I stumbled over your blog entry: great! Thanks for your effort.

Unfortunately it didn't work with my device :/ Probably I messed up the upgrade sequence...

I have a Cybook Odyssey HD Frontlight (a german Thalia branded one).

I installed the .bin file as instructed.

Then (without a reboot!) I connected Wifi (which I did first time after 2 years or so), so at first a firmware upgrade was offered. I accepted it (I thought this would simply overwrite the existing .bin file - probably not very clever...).

On reboot the jailbreak (!) update went through - with some nice messages of "free like in freedom" :) The firmware upgrade didn't took place.

I activated WLAN, no SSH connection possible (connection refused), so it looks no SSH deamon is listening.

Again I got the firmware upgrade offered, installed it (this time it worked), so I am now at 6.3 build 2340.

Then I installed the jailbreak file again and on reboot it went through as before.

But after reboot and WIFI activation I still can't connect with SSH.

Is this a firmware / device issue? Did I mess things up with my firmware upgrade procedure? Anything I can do on my part?

I have a second device here, same old firmware, so could do other tests if you tell me what to do. Otherwise I would do a clean firmware upgrade first and then install the jailbreak.

Thanks!

Thanks.

1) Can you ping your Odyssey once Wifi is activated ?
2) Try install http://soutade.fr/files/cybook/jailbreak_output/cyboy_test/jailbreak_13_37_65000_cyboy_test.bin

It'll create a report file report.txt in your data partition. Can you send it to me please.

Just a short follow up: I used the file jailbreak_13_37_65000_cyboy.bin from "Cybook Odyssey : All firmwares". Probably I have to pick another one?

Thanks!

At first thanks for your quick support!

That's the content of report.txt:

--snip--
Test presence of dropbear executables
dropbear \n ls -l /mnt/root/usr/sbin/dropbear
-rwxr-xr-x 1 root root 178756 Feb 11 19:38 /mnt/root/usr/sbin/dropbear
OK
dropbearkey \n ls -l /mnt/root/usr/sbin/dropbearkey
-rwxr-xr-x 1 root root 178756 Feb 11 19:42 /mnt/root/usr/sbin/dropbearkey
OK
Test presence of /etc/dropbear \n ls -l /mnt/root/etc/dropbear
--snip--

So binary and key is in place, but config seems to be missing? As well there must be some code to activate dropbear at startup. Maybe there is a problem?

And yes, ping works if Wifi is activated. I configured a static DHCP entry for this device.

Well, i'v been trying to investigate how to draw into the screen of my Nolimbook, but i don't know what to do, i'v decompiled some of the binaries that draw into the screen (for example, eps-display), and all i'v discovered is that all these applications use the Linux Framebuffer to draw into the screen (I think with DirectFB). All these applications use /dev/fb0 as default framebuffer, but it doesn't work for me if i compile an application using that framebuffer, i can't draw anything into the screen.

Any help is welcome!
Greetings!!

I'v investigated a little bit more...

Display is driven by a driver made by Allwinner for the A13 (sun5i) on the Sunxi Linux kernel edition for Allwinner. For working with the display you have to deal with the display controller, aka /dev/disp and with the framebuffer, /dev/fb0.

/dev/disp works receiving IOCTL signals from the system (Signals that are documented on the AllWinner page)

AllWinner page: http://linux-sunxi.org/Sunxi_disp_driver_interface/IOCTL

.h with the IOCTL codes: https://github.com/allwinner-dev-team/android_device_allwinner_common/blob/master/include/drv_display_sun5i.h

The main problem is that you have to deal with /dev/disp first, telling him to set /dev/disp to the Linux /dev/fb0 framebuffer, before launching your app (At least, that's what i think how it works).

But even with all this things i can't write anything on the framebuffer...... :(
I will try to keep working on this...

I have fresh news, but nothing on screen, yet...

I'v compiled the 'strace' tool for ARMEL and i'v tried to trace the 'factory_render_text' binary on
/usr/bin with the next result...

...
open("/dev/fb0", O_RDWR) = 6
open("/dev/disp", O_RDWR) = 8
ioctl(6, FBIOGET_FSCREENINFO or FBIOPUT_CONTRAST, 0xbe977abc) = 0
ioctl(6, FBIOGET_VSCREENINFO, 0xbe977a1c) = 0
ioctl(6, FBIOGET_CONTRAST or FBIOPUT_VSCREENINFO, 0xbe977a1c) = 0
...
ioctl(8, 0x402, 0xbe977af0) = 0
nanosleep({0, 20000000}, NULL) = 0
ioctl(8, 0x405, 0xbe977b30) = 1
nanosleep({0, 10000000}, NULL) = 0
ioctl(8, 0x405, 0xbe977b30) = 1
...
...
close(8) = 0
close(6) = 0
...

Well, as i know, /dev/fb0 works perfectly, it can be written and readed, but it is not updated to the e-ink display.

How i said, i know that there was a IOCTL code, that once sended to /dev/disp, the screen is 'updated' or something, so the content on /dev/fb0 appeared on the device screen. Now, i think that this IOCTL's are really interesting...

ioctl(8, 0x402, 0xbe977af0) = 0
ioctl(8, 0x405, 0xbe977b30) = 1

It sends '0x402' / '0x405' to /dev/disp with some arguments on an structure on '0xbe977af0' [Don't know what content is there since i don't any way to explore the device memory, or GDB, or anything... :'( ]

I think that these codes let you update the screen with the /dev/fb0 content, i'v tried to use it, but since i don't know what content is on these pointers, it's impossible to do anything for me...

Greg, if you can give me any tip it would be really nice to continue investigating on this...
Thank you!

Thanks a lot! Very nice hack. For my device it only worked with the Muse update file. Still, the device asks for an update that seems to remove the SSH access.
(Cybook Odyssey Essential - 6.3.2360 - rebranded for Saraiva - Brazil)
This hack raised me a question, would it be possible to remove the appliance brand? Far better to have a free browser rather than just a specific store.

Hello,

It's strange that Odyssey hardware nows accepts Muse update files...
Whatever, nows you have an SSH server, you can run every appliance you want. But you need to code it before... The main part is to correctly handle the e-ink screen which is not easy at all. There are some distributions for readers, but I think the quality is lesser than original firmware.

Hi Greg, very nice and elegant hack !
But for the moment I haven't been able to apply it on my Ocean.
"update file designed for another device" it says.

I've also been looking for reverse engineering the Cybook Ocean but with a software approach, tweaking the DB's and trying to modify the contents of visible files into the mnt/fat/system directory.
I would be interested if you'd have info about Booken's software and the way it works !
The goal here is to personalize the homescreen and also the "library" DB file.

In the meantime i'll try to apply other versions of your jailbreak !

Best regards and keep on hacking this way !

Hello Imants,

I'm very surprised. As I see here (http://www.ceneo.pl/14763650), it seems that it's a re branded Cybook Odyssey (can you confirm it ?).

The procedure you applied is good. I retested it to be sure. When I copy the "All firmwares" (jailbreak_13_37_65000_cyboy.bin) to my Odyssey (at the root of it) with the name CybUpdate.bin, I get a notification about a new update...

Don't know what happens. Can you send me by email your S/N and firmware version ?

I checked my boo reader version and its 4.0 and why i want to jailbreak is to remove the branded version. is it possible? because they here in sweden are not providing any update and the e-reader is freezing and laggy all the time so i want to try your version. what is your e-mail?

I got the same problem. On CYBOY10-ADL/Cybook Odyssey, jailbreak_13_37_65000_cyboy.bin renamed to CybUpdate.bin and dropped in root, but nothing happens. Perhaps the custom Letto software is blocking manual upgrades?

OK, after a check, the firmware to be used is the one for Cybook, not Muse.

Can you do some tests please :

1) Can you start your reader (after a poweroff) with left and right buttons pushed. Tell me if there the factory application is started or if it's a normal boot

2) Put the file CybUpdate.bin on a SD card, poweroff your reader, poweron with "home" button pushed, it should force the update process

Hi, thanks for your efforts.
I have a Cybook odyssey and since the last over-the-air update it's in error and I can't use it anymore.
It booots and then shows an error message telling me there arer issues with the files on the reader and I should remove them.
I formatted the drive already and it's the same error.

I hoped that putting the CybUpdate.bin file on the reader would trigger an update and fix the issue but nothing happened.
Maybe you've got an idea on what I could try?

Bookeen's reply was to send them the reader for repairs.

Cheers.

No I didn't.
I tried "un-briking" the reader by putting your backup file on the root of the USB drive and restart and that didn't do anything.
I tried copying the backup on the SD card and restart and that didn't do anything either.

I also tried rebooting while holding the button and the reader seems to do some extra filesystem checks.
It ends up with the same error message though.

Maybe I'm doing it wrong and I need to do some magic to get the reader to update from the CybUpdate.bin file.

Thanks for the quick reply.

Hey Greg i would like to thank you very very much. And i also want to ask you: If i do install the update provided online by the seller of the e-reader after installing the firmware tweaked by you, will i loose de SSH server on the e-reader?

I've just installed the firmware provided by you and i'm already connected to the Cybook ereader via SSH.

Ereader: Lev - comercialized by Saraiva, Brazil.
Firmware used: Cybook Muse/Odyssey essential/Odyssey frontlight 2/Nolimbook-6.3.2326
Installation Method: Via microSD card / 2Gb - No tricks needed, worked like a charm, just turned e-reader on and it begun installing.

Note: The ereader selling here in Brazil looks like the Odissey, same enclosure, but the hardware inside it is the Muse Frontlight.

Thank you again Greg!
And long live the

Hello Don,

Thanks for your return. The file format since the Muse readers is a full flash image, so installing updates from Bookeen or Saraiva will overwrite previous installed software (especially SSH server). That was not the case for first Odyssey versions.

Nevertheless, I try to be closest to Bookeen updates and provide the last tweaked firmwares.

Hi Again Greg,

Do you believe that if i upgrade the Muse firmware to a version newer than the jailbroken one i will still be able to reflash it with the 'Jailbrake FW'? Or installing a newer firmware will prevent me to reflash the ereader with an older firmware?

Thanks again !

Decided to ask you that before findind out by myself through the hard way!

Sharing info About Muse Frontlight

Hi,

The frontlight on Muse has 256 intensity levels avaliable;

value 255 = frontlight off
value 0 = full power frontlight (Blinding :)

Command for changing fronlight intensity level is:

frontlight

it is located on '/bin' and is avaliable in the global path so it can be run from anywhere within any folder.

Exs:

Turn On frontlight full power:

frontlight 0

Turn Off frontlight:

frontlight 255

Turn on frontlight minimum intensity

frontlight 254

The best part is that the last value used is keept, so if you use the ereader (GUI) interface only for turning light on/off after running 'frontlight 254' thru SSH, the minimum light intesity is keept.

Thank you again Greg!

Thanks for the tips !

I checked in my old Odyssey Frontlight 1, the only things I see is "/sys/class/leds/frontlight/brightness". The logic is inverted :
echo 0 > /sys/class/leds/frontlight/brightness turn off frontlight
echo 255 > /sys/class/leds/frontlight/brightness is max frontlight
Furthermore, there are less steps for intensity (0-8 is off...) and it's not saved after reboot.

I suppose that the Muse also have some entries like /sys/class/leds/frontlight/brightness or it would be a nice regression.

It's clearly a thing that should be managed by the kernel and not some utility tool, but anyway.
As it is managed by the kernel it's not surprising that it is not stored between reboots!

Hello,

I found these post by chance, as I'm searching to retrieve the french dictionary that is used in the Odyssey.
Maybe someone could have retrieved it and could give it to me ?
thanks

Do you think there is a way to change a cybook into a Raspberry Pi scree?

Hello,

As I know, no one here can handle the screen properly (nor the touch interface). So, screen sharing is not available (even if it could be possible with some works).

The kernel source code for Muse is available on Bookeen's github repository.
Some informations about the screen can be found.

Okay thanks for yours answers!
I believe this is a way to turn Cybook into screen, and without breaking anything, but you need internet:

Hi,

I just bought a Nolim HD+ device, a clone of the Booken muse. I'd like to install the original Booken firmware on it. It seems that the first step is to jailbreak the ereader.
The firmware that is on it right now is the 6.3.2407. On the other hand, the file that on this blog is for FW version 6.3.2326. Should it work anyway? Or is it better not even to try to flash it, as the e-reader could be damaged?

I'm not new at flashing when it comes to mobiles phones and stuff, but this would be my first time for an e-reader, so I feel like I need a bit of guidance.

Thank you in advance.

F.

Hello,

My jailbreak is a valid update file from Bookeen + SSH files. So, install one means downgrade your firmware version. It should not be a problem (no one complains for now), you may lost features + bug correction (maybe).

I saw there is a more recent firmware that comes with adlibris readers (cyboy10f readers ~ odyssey ones), I'll make a jailbreak soon, but i didn't saw it for other platforms.

Ah, fine. I thought that your JB was just a patch to apply over an already existing FW and not a complete FW. I guess that downgrading shouldn't be a real problem, as the build are not that far away...

I'll keep an eye on your blog and I'll tinker with my Ereader when I'll be confident enough.

Thank you a lot for your reply and for sharing your work. Have a nice day!

Sorry, I made a mistake. It's the letto one that have a firmware 6.3.2447 for an Odyssey OMAP platform (released on january). This is the old one. With this platform, the jailbreak only add SSH files without modifying installed stuff. So, I don't need to do another update.

Hi Greg,

thanks again for your reply. Sorry, I'm probably becoming a bit more stupid every day, but I still didn't understand if I can safely install:

Cybook Muse/Odyssey essential/Odyssey frontlight 2/Nolimbook : 6.3.2326

in my Nolim hd+ with firmware 6.3.2407

In my understanding, installing it will only add SSH+Jailbreak, without touching the already installed firmware, right?
My concern is if the patch with build 2326 would work on my 2407 build, or if it could brick my ereader.

Thanks a lot in advance.

No problems, my explanation could be confusing.

There is two kind of upgrades : the old one (Odyssey/Ocean) that just add files and the new one (Odyssey 2/Muse) that replaces the whole system image.

In both cases I base my jailbreak on original firmware. I just add SSH files.

In your case, you can safely apply your jailbreak, but it will downgrade your firmware version.

I hope it's clearer now.

Hi,

yes now it's much clearer, thanks. I guess that in the case of a downgrade with your firmware, the ereader will be stuck forever on 2326 version. But it shouldn't be a problem.

Thanks again!

Hi Greg,

On a russian website I've found a link for the latest (or at least newer) firmware for Cybook Muse Frontlight

http://fw.bookeen.com/fw_test/newfeatures/aw13/2350_F1/CybUpdate.bin

(source: http://4pda.ru/forum/lofiversion/index.php?t634896-220.html)

I had to use google translate...

It seems to be version 2350. I put it here just in case you're interested in dissecting it as well (and for othe people to play with it, if they want to).

Greetings,

F.

By the way, to be honest the "GAME_OVER" was put there only to mark the end of the file and used to detect if the file was completely downloaded or not. The fact about the text itself wasn't to be arrogant, but just a pun on some other file format and the fact that as we are at the end of the file, the game is over.

Hi!

I've tried your modified firmware on my Frontlight 2 - it was definitely a downgrade, and apparently everything went fine, BUT.

For some reason the following happened:

- Display colors are inverted
- Display has white vertical lines every few mm's
- Touch screen does not work
- Putting the device in sleep mode crashes it and reboots

Funny thing is, the inversion/lining only appears AFTER boot, the boot splash has no such issues. So I'd guess it's a kernel issue.

Do you, by any chance, have a later firmware for the Frontlight 2? With, or without your SSH additions. It'd be greatly appreciated if I did not have to return my device saying "it happened overnight".

Hope it helps.

But do you have a "real" Bookeen or is it a rebranded version? Because this file can be installed only on the original Muse HD, AFAIK.

Well, if this happen even with the original firmware, I would guess there may be an HW problem then. I tried that FW on a rebranded Nolim+ HD and (aftern changing the S/N) and it is working beautifully...

With the original FW installed, you can surely ask Bookeen to fix the reader (yeah, you can say them that "it happened overnight").
Anyway, you could also try to contact their support here

https://service.bookeen.com/en/&languageid=1

They are very responsive. Obviously don't tell them that you tried to root your device...

Hi! Thank you so much for your work! Like another commenter, I also own a Saraiva Lev which is based off the Cybook Muse (weirdly, in an Odyssey shell).

I managed to poke around with SSH and SCP and eventually clone the root for backup (but haven't tried dumping all NANDs yet).

I would like to know if there's any way to reflash it with the original Cybook software? Saraiva locked it out to their own e-book store and removed the web browser, which I'd like to use.

If I remember correctly, Saraiva is using the same firmware like Bookeen, the difference is just the serial number. Just flash the appropriate firmware from here and later change the serial number (first part) like it is described here. Should work.

Hi, sorry for dumb question.
I've red your article http://blog.soutade.fr/post/2015/07/how-to-make-custom-rom-for-cybook-e-readers.html and decompressed latest beta firmware (2350 build for cybook muse).
Can you or someone else give me a hint about where UI files are? I looked at almost all files and can't tell from their names which could be related to the UI (except icons).
I want to try to change default store link. And if it's possible also get rid of screensaver's warning about sleep mode so one can see the whole screensaver picture.
Thanks.

Hello,

I looked at files into decompressed archive. It seems that the same way of work is used for both old Odyssey and current Muse systems : all (except some icons and bitmap files) is embedded into application. Application is responsible of drawing UI with basic routines like drawLine, drawCircle... It's hard to hack it because it's a very big application.

Bonjour Robby,

Normalement, tout est inclus dans l'archive (dont la police de caractères). Si vous y avez accès par un autre moyen, il faut la copier (via scp) dans le répertoire adéquat.

Je vérifierai s'il n'y a pas de nouvelles mises à jour dans la semaine, mais Bookeen n'en publie désormais que très rarement.

Switching back to firmware 2350 should remove some functionalities and bug fixes made since this version (ChangeLog is not public). Don't remember if this version has a default book store.

Tried to install 2536, no joy.nd I said yes. Reader noticed update package and asked should it be installed, after reboot reader still report as "2538" and connection via ssh fails. There is now folder named FSCK0000.REC in my Muse.

I'll try again.

2538 version means the downgrade have failed. There is a number version for each part and rootfs may have not been upgraded. I can try to provides you a special downgrade package.

Thanks. I tried to go further back to 2350. It installed as well, but does not work any better than 2536. If I could get this to activate wifi, I would have a change to get access via ssh and try to figure out what is wrong. Alternatively the device might try to update itself to original firmware.

Anyway, I'm open to suggestions and if you can provide some specil version of firmware, can try that too.

Are you sure that they use the exact same update for all the model? They've done that in the past where the same release number was not necessarily useful to know for which model it was intended.

You're right. We should use S/N + model identification.

I found that there is a lot of variant hardware for the same commercial name.

We should also find a way to patch hardware without using an update file.

Second try and the update finished, device rebooted. But but. Touch screen is out of calibration, or it appears to be. In the middle of the screen touch is detected to be one row higher than it actually is. In the lower part of the screen difference is far greater. If press the middle key and try to touch "Start/beginning" or whatever the go to base mode is, the touch is registered on the "library" level and a book is opened. Damn. I will try to work this out and report back.

I'm unable to activate wifi and thus ssh. I have now installed 6.3.2350 and it behaves similarly to 6.3.2536. Touch detection is off. It actually behaves like it would think that the screen is bigger, the difference is smaller on the upper part and greater in the lower part.

Warning about screen calibration script: before activating it by removeing /store/.calibrated and starting the calibration proces under /etc/init.d/ , be sure you have killed those two processes mentioned above in this blog.

If your screen failes to calibrate, you need to be able to put .calibrated -marker back before hou reboot the device. Otherwise you get stuck into calibration and are not able to recover the device.

I'm not sure it is the firmware package itself or maybe it is the device I have. I just got another Muse HD, firmware 2538 like the previous one I have now in unusable state. Could be that 5538 is for Elisa Kirja (https://kirja.elisa.fi/) bound devices.I have access to a third Muse HD which I bought for my wife, but as she has not activated it yet I have not been checked its firmware version.

At the moment I am not able to offer more information, but I plan to do some more indepth studies and report back.

Hello Greg,
just a small e-mail to thanks you for your work. I've bought a Nolim+HD reader in Carrefour 3 weeks ago for 50€ (after my 5 years old Kobo died) and I was going crazy facing a lot of problem (losing pages and marks, lot of lags etc...). I've just installed your firmware and now it works perfectly and so fast it's incredible.
Merci beaucoup pour ton boulot.

Houston, we have a problem. I do not blame anyone because I knew I was taking a risk. Nolim XL (Cybook Ocean) Attempt to root with the first files of the list of downloads: it indicates that initiates the upgrade but this does not finish. With the 3rd or 4th file the upgrade is finally completed but ... once the screen is restarted, it will appear faded with horizontal gray lines. I try upgrades again with all the files (including "Cybook Ocean 6.2.2316" and "Cybook Odyssey backup 6.2.2316".) All them complete the upgrade but none return the screen to its correct resolution (?). Any solution? I give the device by bricked? Thanks

Look at the XL specs "CortexA8 at 1Ghz"

This is not the same hardware as the Cybook Ocean (OMAP3611 @ 600-800Mhz) but another AllWinner A8 product.
So same thing as the latest Odyssey that was transformed into AllWinner A8 and had nothing in common with the original line.

As Bookeen seems to no longer want to produce product with their own name, I fear that you will have to find a proper update for the Nolim HD

Thanks for your S/N. Unfortunately I can't access to the original ROM (no update available for now). Did you tried version 6.3.2536 for Muse HD ? It's also based on an Cortex A8 and has a more recent version. The screen size is different, so I don't know if it will be better or worst...

The result with file "6.3.2536 for Muse" is partly better and in part worse. I explain: the screen returns to its white background again. Finally disappear grays horizontal lines. But instead the device does not start: the screen shows a drawing of the device in a horizontal position and with two arrows forming a circle. I interpreted that they invited me to restart the device but, when I do (long press on the start button), it returns me to the same drawing. What do you think, now that I have the screen "clean", should I re-test the file "Cybook Ocean 6.2.2316"?

I’ve tried different procedure to reboot : holding start button, with - without other button left right center, usb on, usb off... I’ve opened the nolim to connect off the batery, to see if there is a reset switch. Nothing.
No new idea to try. Have you another one ?

I'm really sorry for you. There is maybe a serial port that you can solder on the board and try to recover from that, but I'm not sure.

Well..

Toni, try the SD card recovery: http://linux-sunxi.org/FEL#Through_a_special_SD_card_image
But once the device is in FEL mode, I don't know what to do, Greg may have an idea?

For the quality, I can't say for sure exactly, but in the last 4 years, Bookeen seems to had a huge turn over on the firmware side so... I would not be surprised that the quality going down is not related (I'm sure they lost at least 3 person on that role in a couple of years)

And you know my point of view, but the muse and derivative have a really bad firmware. (BK went from a nearly full control of the hardware/software to going back to ODM)

It's a very interesting link, thanks a lot. If we can access to a remote Linux on a non jailbreaked device, we could do a full ROM copy with "dd" and upload them to have recover images. One limitation maybe concerning screen calibration (hope it's not needed).

We need someone to try this, I don't own a Muse for now.

Thanks for the link. Extremely interesting. Muse has serial port on pcb (pads), with TTL level signals. Haven't yet gotten around trying it out, still waiting for parts. Plan A is to use spring loaded test pins to connect to the pads, I would like to avoid soldering just for this. Plan B is to solder wires on the pads and see what happens on terminal when the device boots up.

It depends whether or not there is a bootloader and what kind on the allwinner chip, but as there is the serial port, there might be something useful.

I prefer to try plan-A, as that would enable me to connect to other Muse's I have available without a mess on PCB.

There's even plan-c: desolder the emmc and connect it on, say , raspberry pi. This way you can install just about what ever you want on it. Then just solder it back to the original device. Your link just gave another option to try.

Probably better to dump the whole eMMC and not just partitions:

dd if=/dev/mmcblk0 of=file.iso bs=4096

I'm not sure which block device the are using, and don't forget to write the output file on a device that have enough space :)

I would recommend to run (and not on the target as it would take forever) a

bzip2 -9 file.iso

before sharing the file, there must be a lot of blank area and the file size would decrease dramatically!

Sorry, my syntax is wrong, you need to do dd if=/dev/sdf of=nolimxl.iso.

Whatever, this command line will only dump data from rootfs partition (the only one visible from your computer).

The manipulation we want to do is to connect with serial port and dump other partitions/full eMMC which is not possible via gParted.

Hey Greg, thanks for your work. I installed your jailbreak on my Odyssey FrontLight 2, and the root access and ssh server work. Unfortunately, the colors are now inverted and every second line of pixels is blank. I tried to install other versions, 2322, 2326 and 2350 (with and without jailbreak), but the problem persists. The splash screen is still working as it should, but after booting the lines appear. This makes me suspect it's a software problem, and not a hardware fault. Could someone maybe help me with this issue?

Hey,

I also have a swedish Letto Frontlight (a version of the Muse Frontlight). It's on version 2537. I'm trying to install 2326, 2326 or 2350. It goes through the update process but then boots back to version 2537 without jailbreak. No Jailbreak works for version above 2340? Would be great to be able to get into the filesystem to add more dictionaries.

I just bought the same Letto Frontlight as you and would like to jailbreak it, as I am French and the Swedish store and dictionary are quite useless for me... (Got it second hand and cheap). I has the version 2537 too.
Did you manage to jailbreak yours? If yes, how did you do it?

Bonjour...
je suis désolé je viens t'embêter avec une petite question.
J'avais fait tout le nécessaire en 2017 et du coup je suis un peu rouillé :(
Ma liseuse Nolim est devenu donc une Cybook HD en 6.3.2350 et j'aimerai la passer en 6.3.2536 pour avoir la dernière version.
Du coup pour mettre à jour est-ce que je dois juste mettre le fichier .bin renommer et démarrer la liseuse ?
Et si jamais j'ai des gros bug, puis-je revenir en arrière ?
Je te remercie d'avance.
Très bonne journée :)

Salut,

Tu as bon pour la procédure. Malheureusement, je ne peux pas garantir que la mise à jour fonctionne et ne casse rien. Il n'est possible de revenir en arrière que si tout fonctionne, mais pas mal de monde a eu des problèmes ces derniers temps, donc je ne conseille pas de faire un saut de version aussi grand.

Merci d'avance de ta reponse.

Bonjour,
T'as eu une réponse à ta question ?

Qu'est ce qu'elle donne ta liseuse ? C'est celle à 39 que tu as pris ou à 9 ?

Bonjour,
J'ai également acheté la Nolim HD aujourd'hui chez C. à 9€.
J'ai essayé de mettre à jour avec l'un des firmwares de la Muse (et même celui de la Nolim) mais cela ne fonctionne pas.
Le processus d'update semble se passer correctement mais au démarrage, tjrs le firmware d'origine.
La liseuse est en 6.3.2477.
Merci pour vos réponses.

Salut les gars,

Même chose pour moi :-(
Nolim achetée chez C. à 9€ il y a une semaine.
Impossible d'upgrader la liseuse : firmware détecté, la mise à jour démarre, se poursuit jusqu'au bout sans erreur mais au reboot toujours le même logo et version inchangée (version 6.3.2477).
Je suis dispo pour faire des tests si besoin.

Hello Greg,
Which jailbreak version should I use for Nolimbook XL. What I understood from the discussions is that Cybook Ocean is not similar to Nolimbook XL in terms of the hardware. And Toni bricked his machine while using the Cybook Ocean 6.2.2316 version. When I download the file now I get 6.2.2317 version. Is the problem solved now with the new update?
I have also downloaded the ISO of original Nolimbook XL rom. In the case of a failure, should I just copy paste the files in the root folder?(Given that the read will still be detected in my PC). Thanks in Advance.

If I correctly understand bookeen numbering, I don't have updates for XL series. The hardware is the same of NEW Ocean version, but there is some old ones were it's different.

Did you already applied the jailbreak ?

You cannot make a copy of the root directory by plugging it on your computer and do raw copy, you only get what is exposed by the reader which is user files.

I didn't apply the jailbreak yet. I wanted to make sure if I can rollback in the case of a failure. I bought it yesterday, I don't want to make it a brick in one day of use. Though I would like to have Eng-Eng dictionary which is unavailable in the French version.
So you mean that I can use the NEW Ocean jailbreak 6.2.2317 (No. 2 in your list) and apply it to my device? Do you recommend any way to roll-back in case of problems?

Ok. Do not apply the second jailbreak, it's for old devices and there is no easy way to rollback. Maybe the one for nolim works, but it's clearly not guaranted. What is the current version of your software ?

Hello,

I think that "Nolimbook HD" firmware should work. But the version is behind yours, so you may have less functions and/or more bugs. Plus, I cannot guarantee anything about firmware flashing. I don't have any Muse/Nolim device thus I can't test it.

I tried the "Nolimbook HD" on an AWA13, and while the update was detected, it doesn't appear to have had any effect (no error, no other message, the About menu still reports the same software version, and port 22 is still closed).

Hello,

The hardest part is to manage screen (display + erase) and touchscreen features. The reader software itsel is built upon glibc and some other Linux/Android stuff which should be common to other platforms.

I quickly look at Koreader code and I think it won't be easy to port it. Good luck if you want to.

Bonjour,

Nolimbook HD 6.3.2325 jailbreaké puis transformé en Muse Frontlight avec les indications de Plouf le chien, que je remercie.
Puis mise à jour automatique en 6.3.2326
Essais concluants d'ADB avec le GUI QtADB, pour naviguer dans l'arborescence.

En mode shell, je me suis aperçu que la plupart des dossiers internes sont en mode "read-only", en particulier celui qui contient les écrans de veille. Est-ce possible et dangereux d'autoriser l'écriture sur ce dossier pour ajouter des écrans de veille : pour le Muse Frontlight, ces fichiers sont de la forme :
dsbk_oyX.png
X allant de 1 à 6, en rajouter , par exemple, un septième.
Je n'ose pas trop essayer sans avis éclairé...

La version actuelle est boo Reader 5.2 (1970).
Puis-je la mettre à jour avec le jailbreak ou fait-elle partie de celles qui posent problème lors de cette procédure ?

Hallo Grégory,
Questions de noob: ce routage me permettra-t-il d’avoir accès aux images de veille par déafut et de les changer? Me permettra-t-il d’(essayer d’)installer un clavier BÉPO?

Je n’arrive pas à trouver l’adresse IP de la liseuse sur l’interface web de mon modem, la seule chose qui s’affiche est l’adresse MAC, pourrais-tu donner une commande qui permette de la trouver?
Cela posé, maintenant que l’adb est activable, est-ce que la commande ssh ne peut pas être remplacée par son pendant sudo adb? Quelle serait cette commande adb?
Enfin, comment tue-ton _ebrmain_ et _boordr_?
Merci pour ton aide…

Merci!

Salut,

Pour les images de veille, tu pourras les modifier une fois connecté en remontant le système de fichier en lecture/écriture (voir commentaire #251). Par contre je ne connais pas le dossier exact, ni le format des fichiers utilisés (PNG devrait être supporté).
Pour le clavier BÉPO : non, cela fait partie de l'application.
Pour l'adresse IP ... je ne peux rien faire, il faut chercher sur le net par rapport à la référence de ta box. Trouve ta propre IP, celle de la liseuse ne devrait pas être trop éloignée.
ADB peut parfaitement replacer SSH (ça passe par le câble USB, plutôt que le réseau Wifi). Quelques commandes (pour Android, ce qui nous intéresse est pull, push et shell) : https://www.android-mt.com/tutoriel/liste-des-commandes-adb-et-fastboot-loutil-indispensable-du-super-utilisateur-android/74897/
Pour tuer un programme : killall -9 <programme>, soit killall -9 ebrmain.
On peut aussi utiliser la commande kill en récupérant le PID du programme via ps [ax].

Hi, I'm not a program, but I have a really interest to customize my e-reader to use it for write proposes. I have a brazilian version of Cybook (called here as "lev") and, for the screens I saw the firmware should be the same.
My question is: Is there any way to I transform my e-reader in a some kind of display for my notebook? I see a guy doing this using an android e-reader.
Sorry for my bad english, I hope you can helpe me

Hello,

It's possible in theory, but requires a lot of software development and the result should be very slow. Bookeen readers are slow and have not a lot of memory, it's perfect for reading and saving battery, not to do heavy computing. Plus it's mainly custom embedded software while Android offers so much high level functions.

What I really need is use the display to type my texts (even using my notebook display with these "blue light filters" the experience is really tiring for the eyes. Do you think there is a simpler solution?
Like an OTG compatibility to use a keyboard (just an exemple)

It could, but it's not builtin (or it's an hidden feature...).

For this kind of usage I would suggest a >10" tablet (like reMarkable or Sony DPT-CP1) to really feel comfortable. From my point of view 6" is too small.

First, thanks a lot for this amazing work. I'd be happy to try, but I'd like first to make sure I can go back to the old state if something goes wrong, so I'd like to try to connect to the serial interface and do a dd of the eMMC/all partitions. And it seems to be useful for you as well, so if I can help I would be happy. However, I'm very new to this kind of stuff (I just used UART on some raspberrypi before), so some documentation would be super useful.
I have a UART to usb device, and my book is standard Nolim, AWA13, 1G, build 6.3.2553. Do you have any instructions thut explains how to open the ereader without breaking it, how to connect to the serial port (which pin is the target?), and what to do to copy the eMMC?
Thanks!

Hello,

Thanks. If you want to test without flashing a whole image, just use the ADB method which don't modify anything on the reader. The only page concerning hardware hack is here : https://linux-sunxi.org/Bookeen_Muse
Hope it'll be usefull. If you try to open your reader, don't forget to update the page.

The adb method works greatly! I had root access in a second. Thanks a lot! So as KotCzarny said (thanks a *lot* to him), I'm running a Nolim AWA13 (Allwinner A13) with id cf677bk... serial number, on build 6.3.2553. The ereader as a Carta display and is more recent I think, it has a full plastic cover all around it. This adb method is great if you want to avoid to break the plastic by opening the case or brick the device. I also maid some dd of the card, if anyone is interested let me know (I don't have much space online, but if you want to host it feel free).
My next goal is to try to see if somehow I can use the browser + adb tcp to get shell access directly from the browser, or use some tricks to find a way to run my own programs on it, maybe by watching some specific files, like "run my program when the book XXX is on page YYY"... But I also want to make sure it does not ruin the battery... Fun is starting !

If you are speaking about the Cybook Muse, opening it is quite easy. There is a seam/crack where the backcover is connected to the mainframe. The best is to start at the upper side. It is just clicked together. But remember the screen ist glued to the main part of the housing so just remove the backcover and don't try to remove the screen from the case.

Hello,

I cannot guarantee a valid firmware for your version (all currents are beyond yours). But, with adb you can do everything you would have done with a network SSH access. You can update things if you remount the main partition in rw (See #251).

Bonjour tout le monde,
J'ai finalement sauté le pas et upgradé ma nolim de 6.3.2326 à 6.3.2350. Et ca fonctionne.

Là j'ai pris les exécutable de la MUSE HD en version 6.3.2536 et je les ai exécuté depuis adb, et ça fonctionne aussi !

Mais bon, je ne connais pas les différences et je ne la vois pas non plus.
j'aurai espéré un centrage possible de pages dans l'interface pour la lecture de manga.

Merci pour adb

Hi Greg and folks,

I own a Cybook Odyssey version "OMAP3611", I flashed multiple times the ebook with:

- Cybook Odyssey : All firmwares
- Cybook Muse/Odyssey essential : 6.3.2326
- Cybook Muse/Odyssey essential/Odyssey frontlight 2/Nolimbook Testing version : 6.3.2350

Everything worked as expexted. I can connect to the ebook via SSH but for a reason that I don't understand, the "About" page still show

- Boo Reader Version 6.2 (build 2316)

Is that normal? why it doesn't show 6.3.2326 or 6.3.2350? Do I need to do some special reset?


Je te remercie d'avance pour ta réponse et pour cette page.

Hello

Only the "Cybook Odyssey : All firmwares" can work on an OMAP based Odyssey, and it *does not* update the firmware.

All other (Muse, Odyssey Essential, Nolimbook, etc..) files are not compatible with OMAP devices (not the same upgrade process at all) so no, these have not "worked as expected". The update app should have showed a message saying that the "CybUpdate.bin" file was invalid.

Hello,

Strangely, I had no error during the update process with all the mentioned files. The process go until the 5/5 and reboot normaly.

Some people was able to update the "boo reader" and have a more up-to-date firmware with a device from 2013 "comment #26". Mine is showing 2014.

The device is: Cybook Odyssey HD Frontlight, model N°: CYBOY3F-BK

I'm not able anymore to read ebooks as the book store say I have an old device :s

Unfortunately the build 2316 is the latest ever made that "support" all OMAP based devices. The reason why are just that they loss some key people, not because the OMAP device could not run the "latest" version of the software. Far from that.

The people who said their version changes are people using AllWinner chips and not OMAPs.

The allwinner update really can't run on an omap device, but as the update app will reboot in case on an error, you may have missed it.

It should display something like: http://www.mirari.fr/mzGd



And seriously, they disallow the use of these devices on the store? :facepalm:

Hello folks,

Thank you for the clarification, as you said the device reboot fast that I can't see the error.

Unfortunately, the default store and Swiss library are disallowing this device. You receive a notification that the device is not supported anymore :/

Do you guys have any idea if there's some opensource project or other fork firmware that I can use with this device to keep using it?


It's really sad to throw it because the ebook is still in a good condition. So I prefer to try any hack ;)

Hello,

You can try to change your serial number in nvram (see comment #27). Be careful if you do it, I cannot guarantee it won't break something on your reader !

Hello Greg,

My default serial number is already starting with the BK615BK3F...

Do you mean I can try to change it to BK645...? or the comment #27 is only related to the serial starting with CF616.. devices

Thank you for all the answers you already provided

Do not change that part of the serial number (and unless BK have done something dumb, which is possible) you can't change the serial number on the OMAP devices.

It is made as AABBCDDEGYMDSSSSFL

AA is the reseler (BK is for Bookeen, CF for Carrefour, ..)
BB is the screen type
C is some options linked with the screen
DD is the device color (BK == Black)
E is the hardware revision
G is option fitted on the hardware
Y is the year of manufacture
M is the month
D is the day
SSSS is the build number of the day
F is the factory
L is the line in the factory

Some internal tools need these value to work properly. The only value that are "safe" to change are reseller, color, and all the manufacture info.

Also please note that DRMs are linked with the serial number. You change it, you loose access to the DRMed files.

Small mistake.

C is in fact the device generation (as in 3 = Gen3/Opus, 4 = Orizon, 5 = Odyssey/HD/Ocean, 6 = Muse, 7 = Nolim book/Saga

Also to take note that starting from the Muse they broke the tradition of names starting with an O.. :(

Just for the record (works eventually with first Odyssey Patch)

Model : BK826BK1F (Cybook OCEAN OMAP 3611 - 6.2b2316)

1. Try to setup ADB : Failed (probably due to OMAP Arch)
(Open/Close ADB option is available, but it does not work
(Only One USB Config and One Interface dedicated to Mass-Storage and no open port on Wifi network)).

2. Try to update with Cybook Ocean patch : Failed with message "not the right device" at step 4

3. Fallback to Odyssey arch : Patch Ok, and it is working fine

Hope this can help people with the same device.

Thank you for your effort to free CyBook devices.

Thank you very much for your work, it is still usefull in 2021! I have buy a "new" old stock nolimbook hd and was so disappointed by the limitations of the firmware installed on it (my wife owns a bookeen and as no such limitations). So I managed to transform my brand "new"nolimbook hd to a brand new bookeen using the adb method!

Hi, Great work !

I see that you mention the Orizon in your edit notice from 28/05/2015. I'm stuck with one at the moment and was wondering if there's anything that could be done with it ? I don't think it ever got updated. I can access a hidden folder ".qdutil" when mounting under Gnu/Linux, which seems to hold some binaries and scripts.

Do you think there's something to do with it ?

Cheers,
A.

That folder should not exist on a fresh Cybook Orizon, you must have use some tools from your computer that created this folder.

Using Linux, Windows, or Mac OS X will not change what you can access on the device. Would you be able to share the content of that folder?

Thanks a log for sharing that, but what the?!
How come that has been left on a production device?

What's the Model number of your device? (there must be a sticker on the back)
What are the last number of the serial number, if you go from the right side the serial should end with QE8, and have 4 numbers (like 0042) what the number on your device?

Do you know what version of the BooReader software is running on it?

To be frank, I never myself saw that on a device from production. The file use is probably useless for most people as they are not related with system from Bookeen. They were used by Quisda (the company making these reader) for production before the device was then flashed using Bookeen's software. I start to wonder if this device even have Bookeen's software on it..

I'm obviously not Greg and can't get the email you are using to post here, so I've created a temporary onethat will deactivate in about a week: bd17h3br2bb61nu@jetable.org
So please if you are happy to contact me, please I'm interested to know more about the device you have.
(I don't want to put a real one on a comment like that to get ton of spam, I have enough)

Hi, thanks for your interest !

So the model number is CYBOR10-WE and the serial ends with 0841QE8.

I can't really know what version the software is as I can't get in the settings menu or anything.

It looks like it's running Bookeen's software though, as the loading screen suggests on startup ( picture of a dandelion, with Cybook Oryzon ).

I'll get in touch with you via mail in case you need more details.

Thanks for the investigation _L'auteur masqué_.

From myself I don't think I can do something. I removed Orizon support. Plus, my jailbreak just add dropbear software without updating other system files.

I think the solution could be to flash a fresh copy of an Orizon backup, but in this case you need to directly access flash chip which require a bit of specialized hardware.

Ce n'est pas possible, car pour cela il faudrait directement modifier l'application de la liseuse.
Vous pourriez éventuellement soumettre l'idée directement à Bookeen.

En ce qui concerne le clavier/souris, ils ne sont pas non plus supportés via le port USB.

Hello, I have a Muse HD that was on FW 2538 (I believe) and the update 6.3.2536 did not install... but it turned out (found with serial line attached) it was simply a matter of the md5sum in the content file being wrong for the file bootloader.fex. Changing the md5sum to c798..., then retarring/bzipping made the "update" work.

Just want to send thanks for the effort put into this. I just upgraded a Swedish Letto frontlight (muse) to 6.3.2350 and all works good, including ssh login.

One comment:
On updated linux machines ssh will refuse to do the ssh login towards the reader since ssh1 is deprecated. Adding to ~/.ssh/config the following two lines on your linux computer

HostkeyAlgorithms +ssh-rsa
PubkeyAcceptedAlgorithms +ssh-rsa

will fix it. Though technically the connection would be considered "unsafe".

/Andreas

PS. I read online about a firmware 6.3.2406 but can not find any source of that. A user that sent his muse to France for repair had gotten that version on return. If anyone has an update-file for that it would be interesting. DS

Bonjour, mon amie vient d'exhumer sa liseuse Cybook Odyssey est ma demander de la "refaire fonctionner", le problème c'est que le firmware est assez ancien (5.2 build 1780) et plus rien ne fonctionne (pas de proposition de mise à jour, erreur SSL, site bookeen inexistant pour les mises à jours).
Savez-vous où je pourrais trouver le dernier firmware disponible pour cette liseuse et s'il est possible de mettre à jour manuellement (via la carte SD peut être) ?
merci d'avance.

Bonjour Marc,

Bookeen a stoppé la maintenance sur ces anciennes liseuses depuis un certain temps déjà. Mais je peux éventuellement retrouver des firmwares d'origine (non patchés) si vous m'envoyez les information sur le dos de la liseuse (numéro de série, référence...). Ensuite, il suffit de transférer le fichier sur la liseuse et la mise à jour se lance.

Bonjour greg,
Je suis dans la même situation que Marc. Si ce n'est que cela fait longtemps que je n'ai pas mis à jour une Cybook Ocean.
Y a-t-il un moyen d'avoir les derniers firmware, notamment pour que la liseuse aille chercher les livres chez vivlio et non sur bookeen.store ?
Ou bien est-il possible de jailbreaker l'OS pour changer l'adresse de recherche des livres achetés ?
Merci pour votre aide

Bonjour Whelagen,

Comme pour Marc, il me faudrait les informations de la liseuse pour des firmwares officiels. Sinon, il y a ceux patchés en téléchargement en haut de cette page.
Pour changer l'adresse du store, il faut modifier les fichiers présents sur la liseuse. Je ne sais plus s'ils sont directement accessibles ou nécessitent un accès SSH.

Voici le SN que j'ai trouvé sur ma Cybook OCEAN : BK826BK1FEBJ0107X1
Je tente l'accès pas ssh. Sinon j'utiliserai le firmware patchés.
Je suis quand même preneur pour les derniers firmware officiel.
J'écrirai un tuto si je réussis
Merci Marc

De mémoire l'URL pour le shop est dans le logiciel de lecture, pas dans un fichier externe.

Sinon je pense qu'il devrait etre d'utilité publique d'avoir les fichiers de mise a jour disponible en telechargement quelque part, peut etre archive.org, bookeen n'a jamais mis ces fichiers en telechargement et (alors que toutes les liseuses au moins jusqu'a celle avec un OMAP et les allwinner peuvent installer une mise a jour en offline, la disparition du serveur de MaJ a rendu impossible de pouvoir mettre a jour. Sans compter qu'ils n'ont jamais publié certaine version du logiciel sur des machins qui sont parfaitement capable de l'utiliser (j'ai un Odyssey HD Frontlight avec dernier logiciel d'une liseuse Nolim, et ca marche parfaitement, le soft est un gros blob qui integre le support de quasiment toutes leur liseuses (meme si je doute qu'il puisse fonctionner sur un Orizon, ou Gen3/Opus a cause des version des chip ARM dans ces machines, mais techniquement le code supporte ces machines. Il faudrait que je teste un jour tiens au moins sur un Orizon.

Good to hear that there are still users of this reader. My reader has a problem: the menu button and the side buttons do not work. I have traced it down, that button operates and the CPU receives the signal. Therefore I suppose it might be a software problem. I saw older posts with this problem, but I did not find the solution. Can anyone help to find a solution? Thank you.

Hello, I'm still using my Odyssey ! There is not so much new things since ~15 years ! For your issue, I don't think we can do something as Bookeen does not support it anymore.
