Jailbrake Your Kindle – Hack with Fonts, Screensavers, USB Network

September 23, 2010

in Feature,Hacking,Kindle

Yes, it happened again. This time jail-braking works for both Kindle 2 and Kindle 3. Details have been posted on mobileread forum. In order to hack Kindle you’ve to jailbrake Kindle first. There are three hacks currently available:

  • Fonts
  • Screensavers
  • USB network

For jailbraking, you have to careful finding out the appropriate file for your Kindle since the zip file contains installer files for Kindle 2 US-only, Kindle 2 global, kindle 3 3g+wifi US-only, Kindle 3 3g+wifi global, Kindle 3 wifi-only, and Kindle DX.

For font hack, go to this mobileread wiki. It shows step-by-step procedure with pictures.

For screensaver hack, go to this mobileread wiki. It shows step-by-step procedure with pictures as well.

For USB network, here is a caution:

while there is a zipfile for the usbnetwok hack attached here, I won’t provide any support for it, and I strongly discourage anyone not well versed in bare-bone Linux CLI system administration to even try it. It’s far too easy to brick your device/mess up the software with that thing.

Be careful with such hacking! Since this is not official way of doing things, you’ve to everything at your own risk.

Here is some more caution:

Some people reported losing their collections when installing these hacks… It shouldn’t happen, but apparently it’s a bug in the vanilla 2.5 firmware, so make sure you do a Whispernet Sync and/or that you make a backup of your system/collections.json file before doing anything .

Don’t try to force a custom update by rebooting your Kindle. You should *always* install custom hacks via the Settings page. If the ‘Update Your Kindle’ link is greyed out, it’s because you uploaded the wrong binfile for your device. Don’t try to force an install by rebooting. It’ll, at best, fail, and at worst, force you to start your Kindle in recovery mode to delete the offending update.
