Last night I decided I'd had enough of CM7 eating my battery and not letting me record video, so I sbf'd and did the two step tbh gingerbread update, and then installed aosp liberty. Today at work, I didn't want to take the time to set everything back up on my phone, so I tried restoring a backup I made before I went to CM7. It was on the same rom as I was currently on, so I figured it would be the quick way to do it. I ran the restore, and then when it rebooted, the phone just kept rebooting at the Google logo over and over. I figure once I get home I'll just sbf again and set everything up manually. I'm wondering why the restore didn't work, since I wasn't even changing ROMS. What do I need to know about restoring so this won't happen in the future?
