I had the same problem, also with original prime video app (black screen) when coming from a newer rom. Fixed it by flashing the older TZ firmware which I extracted from here. I attached a flashable zip to downgrade only the tz.img.
Thanks! This is working perfectly fine. Even the voice input in LeanKey Keyboard is working!i'm doing experiment on this rom and google assistant seems to work (except voice search) , if you try to type it works. I bet it needs to be tweaked out , maybe removing/blocking alexa and reassigning the voice button on the remote to trigger google assistant
i was right, google assistant works. I've been able to use voice search and use it to control my smart home.
to make it work:
-enable google assistant in atv voice settings
-go home and agree microphone usage trying to make a search
-go in xposed edge pro
-choose a button ( i used volume down for test) and set google assistant on a key ( it is under activity > google > searchactivitytrampoline (don't forget to enable button)
how to use it:
press the chosen button
and press alexa micrphone button and it will work
Strange.. the zip only contains the tz.img. That should not affect system partition or default launcher (didn't happen to me either).thx mate, worked well! Only downside is that leanback launcher is not default anymore after booting (nlack screen) have to long press apps button and sstart leanback. btw is it possible to update leanback launcher to newest version and enable recommendations? none are displayed here - even if selected.
Hopefully it will, but I don't have spare sticks around to spare. Guess I'll have to risk it. Thank you though.

input keyevent <number>which allows you to send keypresses to the device as if you were working with a keyboard.
input mouse tap <x> <y>which allows you to click things on screen using a grid of coordinates. The top left of your screen is x=0 and y=0. The bottom right of your screen is x=1920 and y=1080. Figuring out the exact coordinate of where you want to click will take some trial and error. Don't be afraid to try. Add more x to make the mouse click something right. Add more y to make the mouse click something in the direction of the bottom of the screen.

Thank you very much. What a relief. You're the first beta tester much appreciated.
