Seeing that an upgrade was available, I chose to install it and went through the process normally. Now, the phone is worthless.
While it starts OK, none of the buttons at the bottom work anymore and while I can get to something like "settings" or an app on the desktop, once I do, tapping the screen to advance does not work.
Holding the button on the top to power down does not work. Menu button does not work. And the phone will, after a few minutes, go to black with the exception of the blue line at the top with the time, connection status and battery indicator.
Nothing else works.
Is there some way to override this nonsense and wipe everything out and return to factory defaults?
