X keeps restarting after new charging flex.
Phone keeps restarting after around 3 minutes. Customer came in for charging port replacement. All screws in right place, no long screw damage.
It has had the following to rule out:
Battery and 3 replacement ports. Each flex cable was unplugged one by one to troubleshoot, even with the following unplugged it occurs: Screen Flex (Both), Face ID/Front Cam Flex (All 3), Antenna Flex (Wifi), Lower Antenna, Power Button Flex/Flash & Volume Button Flex & Charging Flex.
I have tried a replacement screen and still occurs. I have checked all the FPC under microscope and very clean and tidy. It cannot be the port surely as it occurs even when not plugged in.
