Hey guys im having a little bit of trouble with my SGS3 Sgh-i747m From Claro Puerto Rico this model is the 4glte version of the sgs3 we have out here, the thing is that i was searching for the 4.3 update for my phone and the only one that i saw was the one for the Rogers and Bells version. It suppose to be the exact same phone since all of the models this company Claro have are the same as the canadians, ok so i flash the 4.3 update of the rogers version from my model and now i dont have service, i got the bars and maybe i can get like 1 minute of data and that's it, another thing is that if i was using an unlock phone the only thing i need to do to make it work is putting the apn settings and im good to go, but with the update that i did to my phone i can put the apn settings but there is a part that changed on the apn settings field. and i dont know if that's the problem cause normally i have to write default,supl on that part and now all i get is three choices to choose and doesnt let me write anything. I wonder if someone from this forum know how can i go back to a Claro PR firmware or if anyone has one that can send it out to me. Its been two days of my search for this kind of files and still no luck and the only ones available the links are down cause they are from hotfile. I manage to downgrade the version of android to 4.1.2 but it's a rogers firmware rooted i did root the phone and install CWM on it so as of now my phone has root access and CWM ready to go, i dont know if theres a Claro PR recovery file here on this forum i looked and didnt saw one,. another thing is,. Can i use roms from the att sgs3 to use them on my phone or not??? the Att version is the i747 and my Claro Puerto Rico version is i747m
