I created a backup of my stock 2.1 using the backup feature in rom manager and I flashed a custom rom to try it out. I wanted to revert back to my stock setup, but when I try to restore from the backup file it completes the restore and i reboot, but it doesn't get past the unlock screen. It boots up, show the unlock screen for 30 seconds or so and it says it is searching for a signal. Then the screen goes off for 30 seconds and comes back on and does the same thing. I left it for 15 minutes and it never gets passed the unlock screen (can't swype the screen to open phone)and I eventually have to reboot. Is there a problem with my backup file or could I be doing something incorrectly?
