TCL TV debloater. I've tried making it as close to stock Android TV as possible without messing up too many core features of Android TV.

This script tries to debloat TCL TVs running Android TV 7.1 and makes them resemble stock Android TV 7.0 as closely as possible.

Tested on: tcl beyondtv v8-r851t02-lf1v634

Core functionality such as Google Assistant, TV input picker, TV image settings etc. still remain. You can uncomment the commented lines to remove them as well.

After you're done with these, if you want to get rid of the Android TV home screen, install an app like Projectivy Launcher first, then remove the Android TV launcher by running adb shell pm uninstall --user 0 com.google.android.tvlauncher.
