Well here my story, had my cyan 920 and was in the car using Nokia drive while listing to Xbox music, after I arrived at the destination, I paused the music and made a phone call. Then my phone got stuck in an endless loop of the music controls on the screen. If I using the back button to exit out, it would just keep exiting Xbox music indefinitely. Volume got reset to zero, and it couldn't get adjusted and the power key did not work. I tried doing a soft reset but it wouldn't work. I tried a hard reset, nothing. The home key functioned so I use the settings to do a reset. That bricked the phone. Endless loop of the AT&T logo and off. If I kept doing the hard reset keys and was plugged in it would then get to the exclamation point. Then I tried the is reset keys, volume up, down, power, down and nothing. But if it tried the hard reset again I got to the spinning gears. I then tried to do a restore and had the same problem I originally had, no volume,music controls on top of screen, back button and power button don't work. So I repeated the whole process, and did not do a restore but a clean reset, and same issue. I'm stuck with a phone I can't use. I'm headed to the AT&T store now...
