Hope someone can help me please because I do not know what to do :(
I recently changed my Galaxy SIII (I747) for the international version 4 brand new cores, the i9300. Everything works perfectly ... When rooting to erase my carrier applications, TELCEL, of Mexico ... I was going great ... until one day when I wake up, I see down the notification bar says "calls only emergency ". Since then I cannot send SMS, calls, or use my mobile data already and put my chip (trimmed), and one "official" is not cut, but far ... And no longer will I quit the battery, and memory chip for a while ... And nothing I entered the Recovery menu: I did all the wipes and Factory Reset ... And nothing flash by Odin a version of Android 4.2.2 ... And nothing I went back to the stock 4.1.2 version of Telcel ... And nothing already checked the APN, network operators Settings> Mobile Networks, settings GSM / WCDMA ... And anything you already installed the patch Ariza. .. And nothing really I'm quite desperate. I knew nothing of the EFS folder until now ... And it never crossed my mind to do backup of that folder ... I do not know if that the problem is because IMEI and S / N displays the cell corresponding to the QE behind the drums ... And I can assure that before having this problem, Do not flash anything except the Root ... And I never deleted anything with root explorer or anything ... I just used Link2SD ... And yes, if I made a backup of CWM before the problem, but since I restored the backup and the problem persists ... I do not know that can happen /: Now I can only use my SIII for internet and games
