step 1: In case, phones auto startup-> try to isolate charge cable, if it done -> replace another cable.
step 2: check the hygienic of socket, if it still error -> isolate and remove capacitor (purple frame).
step 3: if impedance was lost when measure -> check 2 sides of resistance (green frame), If the error was resistance -> replace same value.
step 4: replace chip usb, 5s 5c can be use for each other.
note: the majority of errors were cable or shorting capacitor, replace chip usb at the end. Use 5s 5c replace for a short time but error was unrecognized pc cable later.
