Hi,
I have a Kindle Voyage, serial 9013, wifi only, with firmware 5.9.4
Never jailbroken. It's restart and resetting itself to an earlier state randomly. Here's what I've tried:
(1) Factory reset from the menu. It just reverts itself to an earlier state, but not factory.
(2) Manual reset by holding the power button for 30s. Also reverts itself to an earlier (the same) state.
(3) Manual update thru usb: it reverts itself to the same earlier state.
(4) Manual downgrade thru usb: doesn't work. update in menu always greyed out, no matter what I try.
So, basically, it doesn't do update, manual update, reset, or anything else I've tried. The only thing it does is to revert back to an earlier state which is registered to me and with a few books downloaded. From that state, if I download new books to read, it will randomly restart and do weird stuff, but I haven't find anything that works. Please help.
Thank you.
