Unbootable cycle

[Copdoughnut]

I've got an HTC Touch Pro. I was trying to relock my TP to return it, but it hit the unbootable cycle while flashing the relock NBH. I cannot get it to flash any other NBH file via the SD card, as when it's in when the phone boots up, it displays "Loading..." without changes. I tried running the RUU with the Sprint Stock rom, but it only goes to a progress bar that never fills. Any ideas, any help is appreciated.

if you just got that phone in the past few months..it has the upgraded rom already on board.. you have to flash the ugrade rom off the US sprint touch pro section..
