Hello XDA,
I flashed my Fire HD 8 (2018) from FireOS to LineageOS 17 using this guide ( https://xdaforums.com/t/rom-unlocked-karnak-lineage-17-1-17-july-2020.4134829/ ).
Installation went great, TWRP/LineageOS was working fine. Later as I began to setup the tablet I became unsatisfied with the ROM because the camera and proximity sensor were not working properly for me. I then decided it would be better to flash to a previous Lineage ROM to get better performace/support ( https://xdaforums.com/t/rom-testing-suez-lineage-16-0-05-july-2022.4232785/ )
At this point is when things went wrong. I tried to overwrite/upgrade TWRP from within TWRP using the IMG file posted in the LineageOS 16 guide with this method - https://www.droidwin.com/update-twrp-recovery-android/ (skip to step 4)
Now whenever I try to boot into Recovery Mode all I see is the Amazon Logo, I cannot get the tablet to boot into TWRP recovery. As bad as that is I can still boot into LineageOS 17 which is a relief. I've tried doing the fastboot recovery method but I get the message "FAILED (remote: 'the command you input is restricted on locked hw')"
At this point I'm stuck and reluctant to try too much more, but I'd still like to try the LineageOS 16 ROM.
