After root phone dont want to start - boot. Still is only SAMSUNG and T-Mobile logo.
I tried to instal Dr. Ketan Rom, everything works perfect , root apps , but phone don't see sim card... And when I try to install reperair patch - its fail.
I instaled this. dr ketan rom :N910TUVU1COD6_N910TTMB1COD6_TMB works but system says "insert sim card", whith this a must install :N910T_COD6_BL_Modem but it fails.
Dr. Ketan rom is very nice. I want to have this, or only root my android.
