Phone Hangs in Calibration after Custom Rom is Loaded

[killswitchtool]

I'm thinking it might have been the O2 plus part from the kitchen since I'd never had a problem with the ROM until I included the O2 files from the kitchen. Now I have been trying to reflash to an official ROMset (the official Sprint ROM I had on to begin with) by using the boot to boot loader and running a TITAIMG.nbh file off the memory card however my phone refuses to recognize the file in the boot loader, I'm using a 1gb card formatted to FAT32 at 1024 allocation size with the .nbh file in the root of the memory card.
