LanguageBreak
Jailbreak for any kindle running FW 5.16.2.1.1 or LOWER

You can also attempt the "one-click" method described here: https://github.com/notmarek/LanguageBreak/tree/oneclick

Do not update past 5.16.2.1.1 even after jailbreak, there have been big changes since and everything is broken, only thing you can do on these versions is downgrade (if your jailbreak survived).

Big thanks to Bluebotlabs for all the help along the way and GeorgeYellow and bulltricks for bringing the vulnerability to light

The attached file should always be up-to-date but i recommend using the one found here

Make sure to remove any kind of password lock - if you forget to this and are stuck on the password screen enter 111222777 and the kindle will factory reset.

Your files will be deleted make sure to make a backup.

Installation

Make sure to read the entirety of the instructions before proceeding.

First and foremost make sure that there are no stray .bin files or update.bin.tmp.partial files on the kindle before beginning
Jailbreak

Code:

1. Type ;enter_demo in the Kindle search bar
2. Reboot the device
3. Once in demo mode, skip setting up wifi and enter random values for store registration
4. Skip searching for a demo payload
5. Select the "standard" demo type
6. Press "Done" at the prompt to sideload content.
7. Once the demo is setup, do the "secret gesture" (double finger tap on bottom right of screen then swipe left)
8. Enter the demo configuration menu by typing ;demo into the search bar
9. Select the "Sideload Content" option
10. Copy the contents of the LanguageBreak folder to the Kindle - merging and replacing all files
11. Unplug your kindle and go back to the demo menu
12. Select the "Resell Device" option
13. And press Yes/Resell
14. Now wait for the press power button to start
15. As soon as it appears plug your kindle back to your computer and copy the contents of the LanguageBreak folder into it once again, overwrite files then safely eject
16. Hold the power button as instructed on screen
17. You should be in a language selection menu in a few seconds
18. Choose Chinese (简体中文) (The one above the odd Pseudot language)
19. Your kindle should reboot and you should see some log message on the screen

Post Jailbreak

Code:

1. After the device has rebooted, type ;uzb into the search bar
2. Connect the device to a PC and copy update_hotfix_languagebreak-{language you want to end up with}.bin to the root of the Kindle storage
3. Eject the device and either enter ;dsts or swipe down and select the settings icon to enter the device settings menu
4. Select Update Your Kindle to install the custom hotfix
5. This will take your device out of demo mode and clean up unneeded jailbreak files.

Post Post Jailbreak

Code:

Stuck in chinese, demo or device is managed after jailbreak?
All you need to do is 
;demo => press the right button it should "enter demo" but it will actually reset into normal mode with English 
After this check if you have mkk folder on your kindle - if it's missing reinstall the hotfix and have fun :)

Troubleshooting
Can't seem to get it to work?
