Fire TV Stick 4K (mantis) Downgraded ROMS 6.2.8.0-3233/6.2.7.7-3033/6.2.7.6-2933/6.2.7.1-2493/6.2.6.8-2315

The downgraded, tz fixed 6.2.8.0-3233/6.2.7.7-3033/6.2.7.6-2933/6.2.7.1-2493/6.2.6.8-2315 have been re-edited with this older rom. It's rooted and has a fully removed OTA patch so no more worrying about your 4K auto updating to the latest efuse burner OS. I'm going to slowly release more downgraded roms with this OTA patch on this forum. If you would like to download the latest rom with the older interface, I have a separate page found here


Changelogs For All Downgraded Roms:

No more OTA updates so keep factory resetting as many times as you want! It won't update ever again until you manually flash a rom in TWRP!!!!!!

Your apps work as they should, will test out relocking the bootloader with this at some point.

Amazon FreeTime is now a stub apk for more storage space inside the system

TZ downgrades are necessary when installing these roms in TWRP

6.2.6.8/2315 makes the Imdb TV app disappear on this version

Notes:

If any of you guys are experiencing download issues I'd be glad enough to fix that! Let me know!!!!!!!

Here's the new downgraded 6.2.7.1-2493 OTA patched rom users have been waiting to downgrade!!

6.2.8.0-3233 is here! Enjoy the fast and snappy launcher performance!!!

Patched Roms that don't have Accessibility mods
6.2.7.6-2933
6.2.7.7-3033
6.2.8.0-3233

Issues (NS6268/NS6271/2493/NS6276/2933)

Unlike 6.2.7.7/3033, AV Sync Tuning will not work with these roms. Some apps require a system update for use. Install 6.2.7.7/3033 or 6.2.7.6/2933 to fix.

6.2.6.8-2315 will kick you back to the home menu after going through settings

Work in Progress

Do NOT relock your bootloader. Your stick will be bricked.

@Skel40 Is it possible to roll out the ability to route audio thru USB on this thing like I want to use USB DAC thru OTG /w bypassing android audio drivers so I can route the audio on 3.5mm jack to Aux? Is that gonna work all on AFTV4k? thanks
