Hey all. I'm really stuck here... I was having a 3g data connection issue last week and tried to unroot. It seems my epic has lost its OS. It boots into the (useless) Samsung recovery. I can't get the odin OS flash to complete. I've tried it on win 7, Vista and xp. I've run it as admin and in compatibility modes on win 7 and Vista, too. Help. I'm frustrated.
