Here we go – a jailbreak method that works on Paperwhite devices with Firmware versions 5.2.0, 5.3.0, 5.3.1, 5.3.4, and 5.3.5.
UPDATE 2013-03-19: Please make sure that you are using the latest version of the rescue pack! Standalone versions installed before 2013-03-13, and jailbreaks performed before 2013-03-19, contain a rather serious bug in the rescue pack. If in doubt, re-install the rescue pack (see below for a link), or the jailbreak.
FIRMWARE 5.3.3 and 5.3.6:
This jailbreak cannot be installed on firmware 5.3.3 or 5.3.6.
Downgrade to an older version (e.g., 5.3.1, or any other supported version) first, install the jailbreak there, then update again to the desired version. The jailbreak as such will survive the update (but you have to reinstall the Kindlet developer certificates and the rescue pack – see the “re-installation required” notes below). Downgrading works exactly like upgrading. Put the update_*.bin on the Kindle, and use Menu > Settings, Menu > Update Your Kindle.
Just download the attached zip, extract it and follow the instructions in the README.txt.
By default, the following “components” are installed:
The actual device jailbreak, i.e., the certificate which allows to install custom update packages.The Jailbreak Bridge.The Kindlet developer certificates. (standalone installer package here – re-installation required after firmware update!)The Rescue Pack. (re-installation required after firmware update – INSTALL IT! One day, it might save your Kindle…).
You can disable individual components by editing the jailbreak.sh file, but this isn’t recommended. After all, there is a very good reason for installing every single one of the components, so I recommend to just stick to the defaults.
It is safe to re-apply the procedure as many times as you want – for instance, if you happen to unregister your device, the developer certificates will be deleted. You can simply re-apply the jailbreak to get them back (only on supported firmwares though).
While it is not recommended to remove the jailbreak – after all, it also allows you to debrick the device – , instructions for doing so can be found here.
