Member: 148515 Status: Offline Thanks Meter: 19,531 | hello! start from testing system connector with multimeter: 1. set multimeter to voltage measuring. 2. check bettery voltage, it should be more than 3,7volts 3. set one multimeter probe to some grounded phone part (if you cant find grounded part outside phone- you need to take out small thin wire from negative battery terminal) 4. with second probe touch one by one all phone pins (phone battery attached) (to get better result i would advice to set needle on the end of second probe) memorise pins with voltage between 2,7-2,9volts. those are tx/rx if no such voltages- post PCB picture, maybe someone will recognise it |
