The Linux system tree on the Kindle only has two writable portions:
/mnt/us and /var/local
Over USB, you can only see /mnt/us
All of the rest is hidden from view (or the reach of cp over the USB cable).
The 'jailbreak' (our signature certificate) resides outside of those two sub-trees.
The Amazon update image (which is a complete image, except for /var/local and /mnt/us over-writes everything else - including the certificate and some minor links that make the 'bridging code' work.)
So once you have installed a new image - the system must reboot to re-install the parts of the jailbreak that had been over-written.
The 'Reset (to factory defaults)' button clears both /var/local and /mnt/us.
The main portions of the 'bridge' code lives in /var/local.
So the order:
factory reset -
install update image
Destroys the bridge code and the jailbreak files (in that order).
The order:
install update image -
reboot (part of the update installation) -
factory reset -
Can and will sometimes be survivable.
Usually that requires using the 'hotfix' package (see the order? the re-boot restores the certificate and then the reset deleted everything except the certificate).
