I have these 2 units with very unexpected case...both 2 units were already repaired by other technician before...they are both hanging up during text messaging...so I decided to lift up combo memory...but unfortunately...the A12,A11,H1 clad were broken...I checked it with the schematic diagram...it is indicated...they are all NC...which means No CONNECTION...But the 2 phones are still no power..I believe that those clads are have connection...what do you think or give some suggestion please...thanks
