It sounds like this is more of a mess than it was with the PW3..
This is the kindle that bricked when taken to PNG - something came over the cellular network and is preventing it from booting. It hadn't been flashed with anything wild - so I had hoped a factory reset would fix it. The PW3 I had which suffered the same fate is working fine after a 'fresh' flash.
DO_FACTORY_RESTORE doesn't seem to be doing anything - does this still work in the androidized models? Or is mine just crashing too early in the boot sequence?
Is there any other way I can factory reset? Nuke a particular partition from fastboot maybe?
There is also that mystery image from the PW3 thread -
