At some point, many of us have had this type of problem that surfaced out of the blue on a phone that had been working without a problem for some time.

My suggested or of troubleshooting:

Soft Reset.

Pull the battery and then reboot. I currently have a persistent problem that only allows the phone to recover this way.

If that fails to permit booting, next try the hard reset.

If that fails, a new ROM upload would be my next step. I would make it a minimal load so that you can get your phone "working". I would then go back to a more complete load (you do save your kitchen selections, don't you?)

I believe this happens because some application causes a problem in the registry that prevents one or more critical services from starting up.
