I had a couple of 3.3V serial usb dongles at hand, and tried to make a connection anyway. I tried connecting it straight through, tried a fet based level shifter and a two transistor based level shifter. All from spare parts, and all failed. I rebooted the kindle by removing the battery to ensure I had a clean reboot.
Constant removal of battery during operation, or some "keypresses" may have reached the kindle and somehow destroyed the root partition. When I finally got the serial prompt I saw a bootup procedure, uboot, kernel booting and finally "kinit not found". At that point booting stopped.
I finally received a proper level converter (TI TXB0108), and with the recovery menu still accessible could format the user partition, add the amazon complete update, and start the update from recovery.
