This page list Hacks and Apps that can be added to your Kindle. It's mainly for the Kindle 3 and some for Kindle 2 and 1. For information about Kindle touch hack you can visit: Kindle Touch Hacking

Most of the links on this page are to the MobileRead forum, if you see a related subject from the wiki, please add it to the link, or even replace the link to the forum if the information linked on the wiki is more complete/ up to date.

Most of the content come from here and here, and we try to implement some coding (JB UN LP) to give a better understanding of what is needed for installing each of these applications.

  • JB stand for jailbreak, are any hacks and apps that only need jailbreak.
  • LP refer to launchpad and include jailbreak (you need to jailbreak to install LaunchPad).
  • KJB refer to kindlet jailbreak and include jailbreak and developer keys (you need to jailbreak to install kindlet jailbreak and keys).
  • UN refer to usb networking and doesn't include any other layer (you will need to jailbreak to ensure usbnetworking is functional on your device).


[edit] Hacking the Device

(This section is a work in progress on the main step of hacking the Kindle as a general overview, it applies mainly to Kindle 3 but some of these part will work with earlier version).

The first thing you should start with is positively identifying your exact Kindle model. That should be fairly straightforward once you've taken a peek at our handy S/N table :).

In short the Kindle is a small computer running a Linux 2.6 on an ARM processor, which makes the device easily hackable. There are a few ways of hacking your device, from non intrusive file manipulation, to jail breaking your device to usb networking into the device. Here is a list of how to get you started to use the applications and hacks listed on this page.

[edit] Jail break JB

Jailbreaking your Kindle is quite straightforward and is generally the first step in hacking your device.

Once you have jailbroken your Kindle a lot of other hacks and apps are available for you to install. Some of these hacks will simply change the behaviour of your Kindle (changing font, screensaver, etc.) but other hacks will add complete software and games (readers, chess, etc). In that case you need a launcher or a software that will make this software accessible. Some software is packaged as a kindlet which makes it easier to launch since they appear in your main menu on the Kindle, but most of them won't. That's why in most cases you need to use LaunchPad or kite.

[edit] Downloads & Instructions

Legacy (FW 2.x, 3.x, 4.x) JailBreak.

K5 JailBreak (NB: on a specific range of devices, running a specific range of FW 5.x versions).

[edit] Launchpad LP

To use a lot of the hack and apps on this page you will need launchpad. To install launchpad, you need to have your Kindle jailbroken first. Then you can download launchpad here. Copy the file to your root directory, eject your Kindle, then update the firmware. Once launchpad is installed nothing really changes, but you can start applications that are installed on your Kindle.

[edit] Kindlet

Kindlets are in a way the most sophisticated hacks. They are full applications that are displayed on your home page on your Kindle. Although installing a kindlet is just a matter of copying the .azw file to your documents section on your Kindle, the complete process is a lot longer. You have to copy the signed key (keys that validate the kindlet) into a hidden folder of your Kindle. Now to access these hidden folders you have to connect your Kindle through USB Networking, or you can use a terminal emulator and copy the files from your /mnt/us/ folder (easily accessible) to the location where the files needs to live. Some developers provide also a .bin file that can be installed like launchpad or other firmware upgrade.

[edit] USB networking UN

This gives you the ability to connect to your device remotely through ssh giving you access to the inner core of your Kindle. Accessing the root file system is not dangerous per se but if you haven't ever been in shell mode in a linux system you have to know that you can brick (render reader unusable) your device quite easily.

To install USBnetwork:

A non-conventional way to install USBnetwork:

From the documentation:

This hack, based on ebs' code, restores `usbNetwork functionality.If you don't know what that means, then you probably shouldn't even be trying to use this. If you don't understand half of what's written here, see the previous paragraph. As always, it may void your warranty. I *strongly* recommend having a proper Linux CLI sysadmin background before trying to use this, or you *WILL* probably end up messing your Kindle up. Do *NOT* do anything with this unless your are *REALLY* sure you understand what you're doing.

[edit] Alternative Kindle OS

Duokan is so far the only complete replacement OS for the Kindle. You can install this OS and at the same time still use the Kindle OS as Duokan doesn't overwrite your main system. The installation is pretty straight forward, installing it as a bin, but in many cases you need to remove all your hack and jailbreak before you install Duokan, and in some cases you need to do a complete reset, which could be impractical in some situations. It's going through a rapid growth and changes since 2011 and has changed names numerous times in its life cycle: from Duokan to Duokan Lite, then Duokan 2012, Duokan 2013, and lastly Duokan 2014. It has since been purchased by Xiaomi China.

The original websites at no longer exist

Progress can now be followed on a MIUI forum

  • Duokan 2012 / Duokan Lite - For Kindle 3 (Keyboard) and Kindle 4NT
  • Duokan - Chinese - For Kindle 2 (U.S. and Int'l.), Kindle DX (U.S. and Int'l.) and Kindle DX Graphite. Alternative Kindle OS C. beta.
