I have TWRP v18.104.22.168 installed and downloaded the kindle fire update from the Amazon website:
I renamed the file to update.zip and placed on the kindle fire via USB port. I get "error executing updater binary in zip '/sdcard/update.zip' . I made sure there were no hidden extensions on the update.zip when I renamed the Amazon update bin file.
what should I try next? I did a 'factor reset' from TWRP and it will no longer boot into the Kindle OS (which is fine as it rebooting all the time automatically anyways). However, I can not flash the Amazon rom to get working again.
Can anyone please help? I have spent many hours with no success so far.
