thank you for the instructions. Keep in mind that the Spring clips are just on the other side of the phone, the side without the photo button. Then metal casing is attached to the front and can bend easy. So be careful here. If you get a red light, 5 beeps, and the device turns off, it means you’ve got a physical error code, and you need to investigate. In my case, I disconnected one of the flex cables to one of the cameras, and this needed to be redone.
