hello,
I am using Hong Mi GD-SCDMA. Today I tried upgrade the ROM and it is not successful. Now the handphone can't detect the sim card. I tried click on SIM Management, it won't response.

Is there anyway for me to reset back to factory default?

I tried to reset the factory sett ing (press volume up + power on) and when it reach Sim Card section, it hang..

Pls help. Thank you
