I'm kinda new to flashing ROMs and was trying to flash one using safestrap on my GS3. I couldn't find one that worked and went back to my stock ROM. In the stock ROM cell service completely died and wouldn't work, to combat this problem I removed all ROMs, ROM slots, and wiped the stock ROM cache. Nothing. So then I restored to my nandroid backup I made yesterday and that deleted my OS. Now when I boot it just gets stuck at the second Samsung boot logo (there the first one that just says "Samsung" and "unlocked", then the second on says "Galaxy SIII" or something) now I have no OS and I'm not sure how to fix this, can I get some help please?
Okay, I got the stock firmware installed but I still have no service anywhere. Any ideas?
