The reason I’ve asked this question is that it still shows all signs of life. Still detecting motion, door bell presses, camera is still online, there is still sound, it still runs on the battery… The only thing it didn’t do was charge via the cables in my wall (but that was the reason I tried taking it off in the first place so I can’t say if that’s because of that ribbon cable).

Guess I have some shopping to do then. Thank you for clarifying!
