huge problem need help asap!!!!!!

[XwalkerX]

ok so i have a sprint tp2 thats flashed to the lastest version of mighty rom.

now all of a sudden when i try and charge it with teh wall charger the device thinks it is being plugged into my computer but it still wont charge. i tried to turn it off and let it charge but that didnt seem to work at all.

so i then figured i would charge it via my computer but it doesnt charge and now it wont even sync! so clearly i have a loose usb connection that is not allowing the device to charge but more importantly i cant flash back to the stock sprint rom in order to take it back to the sprint store.

what the hell do i do?

sidenote ive only had the phone for like 2 months. after owning the tp1 and now this tp2 im really really discouraged with the quality of htc products overall.
