when troubleshooting possible hardware issues it's always best to flash a stock shipped rom. and hard-resset a 2nd time after customizations have ran.
i've been running the stock shipped rom on my sprint tp for a few months now, and a few weeks ago my cam froze while taking pics, so I rebooted and it's been dead ever since.
I just picked up the phone to see if it gave me the message you got, and it's working again!!
lucky me.
I don't remember seeing an error before though, it just would hang on a black screen when trying to load.
