My G has been unlocked and rooted but I am unable to backup and reset. When I attempt this using the Menu - factory reset- I get a flashing screen with the green droid and a line below, halfway across the screen. A long press on the Power button restores to 'normal'. Trying the reset/backup in recovery, this also fails. I have taken a picture of the screen when I attempt this.
