Help! I need to un-jailbreak my Kindle 3 Keyboard

gmask · 07-02-2013, 07:04 PM

I need to uninstall my Kindle 3 Keyboard fw 3.4 jailbreak. Unfortunately I used an older version of the jailbreak and the most recent version's uninstaller doesn't appear to be working (can still install screensaver/font hacks).

I do not remember the JB version I installed, so I plan on just downloading all of them and trying them one by one. The problem is I don't know where to find the older versions of the JB; the thread here only lists the latest version.

I am attempting to install Duokan, and it requires an un-jailbroken Kindle (get U007 error when I attempt to install the b008.bin).

@gmask: You're gonna need to remember exactly *which* jailbreak you used, because if you tried my latest uninstaller and your device is still jailbroken, then it wasn't mine

.

Hint: https://www.mobileread.com/forums/sho...d.php?t=122519

And *restart* your Kindle after the uninstall.

@knc1: The FW 3.x jailbreaks are trickier than that

. There's no concept of dev private key, so we're bind-mounting our custom key on top the one of Amazon's one dynamically, right before the updater launches, if we detect a custom update package

.

That means some versions have a 'broken' uninstaller that doesn't restore the default keys after the uninstall process, hence the need for a full restart to kill the bind mount.

@NiLuJe: Fixed, thanks.

Got it: ran the latest uninstaller again and then reset to factory and Duokan installed. Yay.
