I Have (at the time it was a)Compaq iPaq H3950
I found on EMule a .nb0 file
and a terminal software allows me to flash my iPaq in serial mode(power+button

2+4+soft reset)
The flashing went well and my rom is now on version 3
Before I made this WRONG step, i used one of HP tools for BIOS rom update and made a

.nbf backup of my rom!!
but i can't seem to be able to use it, the terminal software doesnt recognize this

file well and the HP Software does not allow me to downgrade NOR UPGRADE from or to

ROM Version 3.0

I Also tried using XDATools (OSFlashROM something) to load the .nbf back to the rom

but it faild to recognize the file format...

Can Anybody help me Please I made myself stuck forever on 3.0...
