My T2 Ultra D5303 detects my sim but there was no signal nor I can't make a call or send sms. Under Sim Status, it shows Voice: Radio Off; Data: Radio Off I can't even change my Preferred network type, even on T2's #*#*7378423*#*# and #*#*4636*#*# (tapping Turn On Radio gave no response) Flashed stock rom .182, remove/insert sim, factory reset, disconnect battery, power off then power on, all gave zero result. Changed antenna cable together with sub-board, still nothing. Has anyone here experienced similar issue on their T2? How did you solve it, or what did you do to solve it? Your vital inputs will be greatly appreciated.
