batterie connector ground of motherboard to ground of unlocking testpoint the same for +

another way to test if charging symptome after bad unlocking is to put a full batterie on the phone : try to turn it on ! it won't turn on :( but if you put the battery on the data cable and try to turn on the phone it will turn on and even charging. datacable is taking power from battery connector ground and + to unlocking test point + and ground ! that's why we put a bridge with 2 wire to make it function :)

BUT LET ME KNOW WHERE IS GROUND OF UNLOCKING TESTPOINT AND "+" OF UNLOCKING TESTPOINT, I SEE ONLY RX, TX AND SOME OTHER CONTACT...
HLP PLZ! THANX 2 ALL!
