My son has an older kindle that I'd love to fix. It crashes and books become corrupted and can't open.

Things I have tried:
-factory reset (freezes and rebooting just boots back to existing situation)
-firmware upgrade (from 4.1.3 to 4.1.4; freezes at the very end and rebooting again boots back into status quo)
-reformat from windows
-reformat in linux
-I've even dd if=/dev/zero of=/dev/sda1 to the partition


What is absolutely crazy to me is I can delete all the books, do a reboot and they re-appear. I've even reformated the kindle and the books re-appear.

Ideally I would like to
-upgrade the firmware
-factory reset

Both freeze, and I can un-freeze it but it just boots back into the status quo.

TIA
