Hi OP - I seem to have created a nightmare. I initially rooted my nieces Kindle shortly after christmas with no issues whatsoever using your guide. Shortly thereafter Amazon released an update that overwrote my changes (why oh why didn't i kill otacerts) and she returned it to me to re-mod. My second attempt was cut short - I hadn't made the contents of Bin4ry or Qemu folders executable and was running into permission denied errors when attempting to execute adb from within the script... after i realized my failure and got access to the device again (tonight) I again attempted to execute the scripts... and bumped into a new troublesome issue... I executed Bin4ry's script and the device rebooted when expected, albeit slowly. I then got to the point where the kindle was flickering the script asked me to unlock the device, which i could do, though responsiveness was slow, and hung on the message saying 'waiting for device to reappear'... it stayed here for well over 20 minutes. I ended up CTRL-C ing that window and tried to find the device using adb devices, but adb was non-responsive. adb kill-server hung as well, so i rebooted my PC and tried adb devices, the kindle is visible (yay!) and i can gain access to the shell, however, and here's my problem, whenever I plug the Kindle into my PC and launch adb shell my PC freezes and I have to power-off and restart. Every time, no matter what.
The kindle is half-way rooted (maybe less) and in a non-operable state... and I can't seem to keep my OS stable long enough to finish... what is going on here? I have to take her home now, am thinking I should try and run the Bin4ry script again but am concerned that my PC may freeze again...
I am updating the SDK as I type, hoping someone more comfortable with the kindles can chime in and lend me some direction, this thing makes me nervous.

TAKE MY ADVICE, DO NOT BUY ANY LG PRODUCTS.
LG LOCKED THE BOOTLOADER ON THE G-SLATE AND REFUSES TO TALK TO DEVELOPERS ABOUT IT.
LG CAN KISS MY ASS.
