thanks for sharing this

I'm trying to get up to speed on kindle jailbreaking so I can (hopefully) contribute in the future. Do you have a writeup on the exploit being used here? From the exploit code I'm assuming it has something to do with dictionary parsing.

digging a bit more seems like it exploited `system()` call in `langpicker.so.1.0:module_langpicker_utilDeleteExt raDictionaries()`

Is this it?

Ok confirmed what I had seen (https://www.mobileread.com/forums/sh...d.php?t=356766)

Sorry for the multiple messages; I'm new to the forum and I can't see a way to edit/update a previous message.

Thanks for making and sharing this jailbreak.

for this jailbreak! it works with my paperwhite 3. did not have any prior experience to jailbreaking and a video tutorial on tiktok plus this helped out a lot. though i did fumble by accident and put english instead of chinese in one of the steps. honestly just wanted the reading statistics and dark mode of koreader

Guys, I am a bit confused by the final steps.

When I get to this:
  1. 13. At this point, a language selection screen appears. Select 简体中文 (Chinese), which should appear above an entry called Pseudot and below Japanese.

My Kindle Oasis restarts, the script output is displayed showing that the jailbreak was succesful, but in the end I get to a demo interface already running in English when I believe it should be Chinese.

So if I try to install the update fix and get out of the demo mode, I end up with no jailbreak.

What am I missing?

Hi everyone, i have already sucessfully ran the jailbreak on 5.14 and everything was working fine with koreader.

Just out of curiosity i tried updating my PW5 to 5.16.2.1.1 with the binaries as is instructed and that was also not a problem, after doing a complete reset of the device to attempt again to jailbreak the device i have come across with the issue that after copying the files during the "Press the Power Button" phase and rebooting by leaving the button pressed until the screen backlight starts up or on multiple attempts even left it pressed after it looped a few times on the kindle logo, the languaje selection never appears and im just loaded directly to the home.


Has anyone come across this issue, im i missing something here?

Never mind my last post, seems like after booting even though there is no message regarding the jailbreak and only the short setup, immediately apply the hotfix directly there and after that first "update" you will see a small message at the bottom once it finishes applying it, something like "MKK keys" (don't remember well), after that again copy the hotfix and update and this time it will show "Jailbreak" on the bottom and entering ;log on the search does show a message and you can see the new folder on ce you connect it to a computer.

Hope this helps another lost person

Thank you Marek very much! I ended up using your upgrade-then-downgrade approach.

Here is the summary:

0) Brand new Kindle Scribe - do not connect to network yet.
1) Check the version. Connect Kindle to PC, in File Explorer open hidden folder /system, open version.txt. If FW is 5.16.2.0.1 or earlier - you are in luck with LanguageBreak! Unplug Kindle from PC.
2) Connect to a public hotspot that requires login in a browser.
3) Kindle Browser will show up. In the address bar type ;enter_demo then hit enter on the keyboard. Restart Kindle (long-press, window pops up - restart).
4) Follor JB instructions in this thread's OP.
5) After the Chinese language selection, it will put you back to demo.
6) Do not leave demo yet, install both Marek's and NiLuJe's hotfixes first.
7) Then type ;demo then hit yes. It will ask about demo but actually let you in normal mode.
8) Here connect Kindle to PC and drop in NiLuJe's hotfix.
9) At that moment we are in the Amazon Out-of-Box Experience screen that lets you sign-in but doesn't have menus, search bars or other meaningful buttons. So, go to the Browser again as in Steps 2-3, this time type ;711 . A screen with network info will show up, but we only need to hit three dots in the corner - Update Your Kindle. I don't know if this hotfix reinstallation step is necesary, but just in case...
10) Restart Kindle Scribe TWICE. Do not sign-in anywere yet. This will make sure JB survives.
11) Sign-in to Amazon, and agree to install updates - this is the annoying part because of which I spent 26 hours in a row (with some sleep in between)
12) Once it updated, go to Airplane mode (to prevent any other updates). Goal is to NOT let happen another update OR factory restore before JB is recovered.
13) Use NiLuJe's K5 Jailbreak package, only extract emergency-bridge-recovery.zip's contents (four files) to Kindle's storage.
14) Restart Kindle, check that four packages are gone. ;log mrpi commands can be used again.
15) Install NiLuje's Hotfix via mrpi.
16) Use this script and run it with ;log runme : https://www.mobileread.com/forums/sh...&postcount=469
17) Now that FW downgrade is possible, download earlier FW version. I went with 5.16.2. "Update" Kindle normally via Update Your Kindle (UYK).
18) Then install Install NiLuje's Hotfix via mrpi or UYK.

Good luck!
Thanks for the tutorial. I got my scribe jb yesterday. Only difference is that for the captive login part I happen to have a xiaomi router that automatically redirects to the admin login page if no internet service is detected. IIRC Netgear routers do the same thing.

And DO NOT block the ota right after the JB, amazon will not let you sign in if the update is unsuccessful.

I had the exact same problem as you, same device as well. Take a look at how I managed to jailbreak my Oasis.

Question Stuck on Step 11

Hi, can someone help me out with jailbreaking my Kindle:
Device: Kindle Paperwhite 6th Gen
Firmware: 5.12.2.2
Guide in use: https://github.com/notmarek/Language...readme-ov-file

The issue is that I'm stuck on step 11 that requires the contents to be recopied once the power off message appears on the display. The issue is that even if i promptly connect the device to the usb, the drive appears for a fraction of second and then immediately disappears. It does not give me a opportunity to open the drive.

Any help is much appreciated!
