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.
