I have a samsung galaxy s3, sgh-i747. I tried to attach pictures of all the specs of phone, to no avail... my problem is: cant get signal.... I have added new apn's, factory reset, new sim holder, and I still cant get signal. even used another sim card, brand new, and other old ones....Android version: 4.1.2, baseband version: 1747UCDMG2, kernel version: 3.0.31-1300972 se.infra@SO210-19#2, SMP PREEMPT Mon Jul 8 19:30:05 kst, build number: JZ054K.1747UCDMG2. wifi works great. no error message when sim card is in.
