so first thing , you conect pcb to nooxbox , then connect pin7 to GND like in pic
after click Read Phone to check if ewrithing is fine , if yes then do unlock
PS: dont forget to connect V+ BSI and GND , also you need to cut the shield.(for data you can use ball Nr3 which is in the same position like pin 5 its more easy. Its working fine and fast the unlock for E65 i made a lot off them with nooox.
