I have been flashing Samsung phones since I got a Fascinate about two years ago. Never had a problem until now. I got bored with my S3 and flashed to Galaxy Mod rom. I liked it and used it for about two weeks. When CM10.1 came out I had to try it. Flashed it and my phone wouldn't boot past the LTE screen. Flashed it again and it booted but now I can't make or receive calls. It says Mobile Network not available when I attempt a call. I can receive texts but not send them. Data works fine. I flashed back to stock and tried some different radios. No luck. I'm gonna send it to Samsung but I hoped some of you may have some ideas. Thanks.
