Running GB 595. Had it themed with BWC and made a nandroid backup of that. Tried a cpl other themes. Didn't like em as much as BWC, so I thought I'd flash the backup. When it opened all I got was force closes. Went back to CWM wiped cache...no help. Went back to CWM data and cache wipe...no help. Reflashed the backup...still got the multiple fc's. Reflashed BWC...bootloop. Reflashed 595...bootloop. And that's where I am now.
Update: Pulled battery, factory reset and cache wipe again in cwm...back up and at start screen in GB 595. Do I dare try and flash that backup again? If so are there any procedues I need to know before or after flashing it to avoid the fc's?
