Hi. I decided that I wanted to go back to the amazon os on my Kindle Fire from OtterX. First, I changed the partition back to "AMAZON". Then, followed this step:
STEP 4: WIPE PARTITIONS IN RECOVERY
[Main Menu] Wipe -> Advanced -> check "Cache" and Swipe
[Main Menu] Reboot -> Recovery (wait for it to come back into TWRP)
[Main Menu] Wipe -> "Format Data", type "yes" and hit enter
[Main Menu] Wipe -> Advanced -> check "System" and Swipe
Then, after I installed the stock prerooted rom for the Kindle Fire, the device will load up at the boot loader, show the original kindle fire logo for a split second, then go back to the bootloader. It was getting late, so I decided to power off the device and work on it the next morning. When I turned it back on. It would only show the OtterX boot loader logo, then the screen will turn black. Then it will do it again and again and again. Is my device bricked? How can I fix it?
