probably not hitting all the three buttons at once...

Sounds like you arent holding the power and camera button when you reset it... Took me a few times to get it too.. I press the power and camera down and then when Im sure I got that I reset it. They dont necessarily need to be pressed at the exact same time. Press all that and hold until bootloader shows up.

Also Ive always named my nbh file in lowercase letters...Dont know if that matters but I would assume if that was the problem bootloader would still show up.
