| hello eswar7983!
as long as a week noone is able to help us- i would advice to finish this by finding pinout by yourself.
i will give you detailed advice how to make this using 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 must be 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 |
