Hello, My Mi5 device suddenly turned off. It does not open without touching the test point as in the video below. Can you help? https://www.youtube.com/watch?v=ED96PJ-q

Geliştir ix  Those are TP 1204 and TP1205. It forces a USB boot when bridged. So every time you plug it in it will boot while bridged. Your issue may be related to something totally different than the forced USB boot. You have tried hard reset etc., what else have you tried? Considered a new battery?

Lots of stuff going on in that video :>) Anyhow are you referring to the temporary bridging of the component shows at ~4:36 in this video? If so do us a favor and post a couple of good pictures of both sides of your phones motherboard. Maybe we can identify issues with components and the circuitry to better assist you.

If you have a Xiaomi phone and have not yet had the opportunity to open it up and test the touch point, here is a guide on how to do so. First of all, find the lock switch on your phone. It is usually located near the bottom left corner. Once you have found the lock switch, press and hold down both buttons at the same time until the phone powers off. Next, use a pin to pry up the screen.
