The reason I am asking this question is due to the fact I f***ed my GT-I9300 up. I wanted to install a custom rom, installed PhilZ Touch Recovery. The recovery failed to wipe the data properly 3 times(*DERP* probably is the cause to the issue). After installing the rom(tried several roms!) every thing seemed to work properly except the cellular network, the phone recognized the SIM and found the network but didn't connect and showed Network: Unknown. I tried using a APN, didn't help, tried a friends SIM to check if it was the SIM same result. Reverted to full factory stock and still the same, after the revert to full stock I sent the phone to warranty repair.
Has anyone had an issue like this or something similar with their GT-I9300?
