KindleBreak (5.10.3-5.13.3*)

This page will guide you through on how to use KindleBreak to Jailbreak your Kindle that's on firmware 5.10.3-5.13.3... with some exceptions.

Info taken from the original thread: https://www.mobileread.com/forums/showthread.php?t=338268

Before we get started, there's a few exceptions with the firmware it supports. Most notably, on the KT2 and PW2 (6th generation hardware), there was a firmware update 5.12.2.2 which patches the exploit KindleBreak uses, in which case you should be using WatchThis instead.

TL;DR of this jailbreak: Download the zip, copy the files to the top level storage of your Kindle, go to file:///mnt/us/kindlebreak.html, wait for it to restart then go to Post Jailbreak.

Prerequisites:

Here is a table on which models are supported, and what firmware versions are supported. Unlike WatchThis, any models with any versions on this table will be supported.

Models	Firmware Version
KOA3 KT4 PW4 KOA2 KT3 KOA KV PW3 KT2 PW2	5.13.3 5.13.2 5.13.1 5.12.5 5.12.4 5.12.3 5.12.2.1.1 5.12.2.1 5.12.2 5.12.1.1 5.12.1 5.11.2 5.11.1.1 5.11.1 5.10.3

Versions that won't work with KindleBreak:

• Anything newer than 5.13.3, in which case you should use WatchThis (5.13.4-5.14.2) instead.

• 5.12.2.2, despite the name, this version is actually newer than 5.13.3. Use WatchThis instead.

• Anything older than 5.10.3.

If you've determined that KindleBreak supports your device/firmware version:

1. Download jb-kindlebreak.zip (MD5: 0215C36CC1E3AD8136A67DAEBE369452)

2. Unzip, now there should be these files:

   • jb

   • jb.sh

   • kindlebreak.html

   • kindlebreak.jxr

3. Connect your Kindle to your computer, then copy the 4 files above to the root of your Kindle's storage (where the documents folder is.)

   

   It should look something like this.
4. Eject and unplug your Kindle.

5. Go to the Experimental Browser from the top right menu, then navigate to

   file:///mnt/us/kindlebreak.html

   (Make sure that it is file:/// and not file://)

6. Your browser should freeze, crash and after some time (this can range from few seconds to several minutes depending on your device) your Kindle will reboot. It'll probably give you some kind of error window with the title along the lines of "Application Error" or "Collecting Debug Info".

Once your device has rebooted, you're finished with the tutorial. Head onto Post Jailbreak section to finish setting up things.
