Updating context since I see activity here and troubleshooting is fun !!

Need your expert guidance @draxie and @DB126 .
Device - Fire HDX 8.9 (3rd Gen)
Bootlocker - Unlocked (method & files used)
Adb & Fastboot - Enabled
TWRP - v3.5.0_9-1 by @ggow
ISSUE - Touch screen alignment is off after flashing a ROM meant for THOR. (this)
Now the TWRP touch is haywire and I could not seem to be able to fix it. These are some of the things I have tried so far after figuring out places to touch to make TWRP work.
Read somewhere that flashing an incorrect ROM in some cases may even break the touchscreen digitizer warranting a replace ! Possibilities?
Thanks in advance.

- Tried a dirty and clean flash of Lineage OS14.1 & 16 through TWRP.
- Tried dirty and clean restore of Lineage OS14.1 & 16 backups through TWRP.
- Erased recovery in fastboot mode and flashed recovery again in both 'recovery' & 'boot' partitions.
- Erased everything (except 'bootloader') --> erased aboot --> flashed aboot for apollo (which was used while unlocking the bootloader) --> flashed recovery.
- Erased everything (except 'bootloader') --> erased aboot --> booted into bulk mode --> on my system (windows) saw only one folder 'image' inside one of the partitions --> didn't make sense to me so copied to system.
- Flash stock rom somehow. As this might result into a hard brick, I wanted to know if there is anything else that I can try before that.
Update - Downloaded Stock Fire OS 4.5.5 from amazon --> updated updater-script --> ADB sideloaded --> Now I have everything stock but the touch issue still persists. (Fortunately I still have ADB, can boot into bootloader, flash aboot, twrp, etc.)
