It is a Kindle Voyage FW: 5.11.1.1 (with special offers)
Been in airplane mode for 5+ years
Followed
https://kindlemodding.org/jailbreaking/WinterBreak/ and everything went fine except I can't get the mesquito to pop up. I read users reporting it taking numerous tries so despite the insanity of doing the exact same thing repeatedly and expecting a different result I made another 12 attempts at it and all failed to get mesquito to pop up.
Undeterred I tried to:
Factory reset in online mode, no change in device
Factory reset in offline mode, no change in device
Factory reset via DO_FACTORY_RESTORE in root folder, no change but file was gone after reboot
When I say "no change" I mean the side loaded books are still there and it's still registered to me.
I tried to reregister the device and that was a nightmare and still resulted in all my sideloaded books returning.
I tried to delete the sideloaded books via calibre and they deleted, until I reboot the device and they returned
I tried to delete the sideloaded books via the file manager and they deleted, until I reboot the device and they return
I tried side loaded a book and then deleted all the books, all the previously side loaded books returned after a reboot but the "new" sideloaded book did not return.
Can someone offer advice here? Is my kindle cooked, it won't save any of my side loaded books if I restart it now (which isn't often but it's annoying)?
