Störungsbeseitigung
We disassembled the phone and checked the motherboard, there wasn’t any obvious damaged area.
We continued to separate the two layers of the motherboard and checked the pads. All the pads were good, and then we tested with a tester socket, all the functions were ok.
We conclude that the problem was from the connection between the two layers. We reballed the layer and solder the two layers together, the iPhone was back to normal.
