Open the phone, power on and check voltage with multimeter on charge connector legs u will find 2 leg with voltage -2.8-3.5 these are tx- rx legs.

try this with multimeter. put battery or external power supply. at the moment when you press power button, check system connector voltage with GND (see picture)
