(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 |
I have 2,7v in pin 3,7,8,9,10 with cell power
