Member: 2146046 Status: Offline Thanks Meter: 62 | I understand how to do this process, I just cannot get my phone to be detected by GCPROKEY. UART port is working, cable is working, phone is in *#0*# mode. But phone will not detect for DRK repair. When I try to do IMEI CERT WRITE, it tells me "Can use only on damaged phone stop here." error. |

Member: 2146046 Status: Offline Thanks Meter: 62 | ** PROBLEM SOLVED ** - I had to flash PI1 Combination File in order to fix DRK Issue. The other combination file firmware was too low which was causing IMEI = Unknown which was causing UART Port not to work. Thanks for the help everyone. Thread Closed |
