I got this message on my HTC Touch Pro 2 after I unlocked the radio using rhodiumw dot htc-unlocks dot com unlocker. I had the standard Sprint ROM, not a custom one, just a standard rom that comes with the phone out of the box, win6.1. Just wanted to unlock the radio so I can use a GSM chip other then sprint outside the country. When I changed the GSM chip, next day I received the exact screen. Had to hard reset. Had a backup
