2 days ago, a friend asked me to look at his XT912. The phone suddenly started crashing apps and processes and had become completely unused. I tried to do a FDR, but when the phone rebooted, it hadn't wiped anything from the phone. The lock screen was still active, the wallpaper was the same and the accounts were still configured. An FDR should have asked for a fresh setup, and it didn't. I tried to disable the lock screen and it won't change. I thought I would try Matt's Droid Utility and brought the phone home with me.
I just ran Matt's utility on the phone and chose the option to restore JB and wipe data. Everything indicated it worked successfully from the computer and the phone rebooted.
When the phone booted up to install the radio information, the screen had the dead droid with the ! inside the red triangle instead of the standing droid with the blew spinning globe. After a short time, the phone did reboot on its own, but hadn't changed anything. The lock screen was still active, wallpaper was still the same. The phone wasn't asking for the fresh setup process.
Any ideas of how I might proceed?
Thanks,
Roger
