The phone gets stuck on the gray screen where the progress bar is shown alongside the percentage #. It just sits on zero and on the PC side is also just sits in the progress pop-up at zero until it automatically kicks me off with an "error" message and number associated with it. (can't remember the error number)

Regarding the swapping of .nbh files, what I did was to extract the files from the Sprint Authorized ROM Upgrade .exe file into another folder. In the new folder into which I extracted the files, I went ahead and deleted the existing .nbh and replaced with a custom .nbh from another ROM (timberwolf671 custom ROM). This didn't work. I figured it should since all custom ROM's I have ever used come in a .rar package. Therefore I figured I'd create my own .rar using the Stock ROM and swapping only the .nbh. To be clear, my folder was a .rar archive, not an .exe "ONLY" file from which everything ran from after the swap. Again, just like how custom ROM's are packaged in .rar files.

Hopefully that clarifies what I did.
