| try to use external power supply,
find pinouts as usual
for test mode operations
1. adjust power supply voltage to 4.2v
2. connect pinfinder to phone using data cable.
3. connect pinfinder's black power cable to phone's - (ground) battery pin. (no connection of pinfinder's red power connetor)
4. connect power supply also to phone's battery pins (both + and -)
now u can do test mode operations without power problems
