Ok, I had some problems with losing the IMEI after flashing CM10 but I was able to restore that. The next problem was I still didn't have service. I tried flashing numerous roms and going back to stock but that didn't work. Finally, I had to restore back to factory settings after recovering with Odin because I couldn't get past the Samsung logo. When it started it comes up with yellow text where the clock is and flashes quickly at the bottom saying that it is in Factory Mode and something about Wi-fi. At the bottom it says that I need to return it back to user mode for verification. Any ideas on how to do that?
