Hey guys! Fist of all sorry if im posting in the wrong forum. I have a problem with my s3 4g, I was gonna root it but i was a bit too fast when doing it i accidentally tried to root with the gt-i9300 version. I'm very lucky though since i didn't brick my phone and it still works but it shows "no sim" and i cant really use it, everything else works so i moved my contact, pics etc to my pc and tried a factory reset but its still the same problem "no Sim". I heard that you can re-flash it somehow but couldn't find any guide on this and also is it the right thing to do? if there is a way to reset it please help me with this!
