Sprint HTC Touch Pro stuck at boot - bricked?

[darmok]

Hi,

I've been using an unlocked Sprint HTC Touch Pro for several months now. I've always used MightyMike Roms and I'm now using his latest version released 07-18.

A couple of hours ago, I soft reset my phone and when the phone restarted, it would not continue after the black screen that says "Touch PRO", I can see the red letters on the bottom of the screen, but nothing else.

I have tried hard resetting it and soft resetting several times, connecting it to the charger and to the computer, and pretty much pushing all sorts of buttons when the phone is resetting. There doesnt seem to be anything that I can do to get it pass the first screen.

Anybody has any ideas? Worst case scenario, if I need to take it to Sprint... would they be able to tell that it's unlocked by the red letters that do display? Would that void my warranty?

Thanks!
