does anybody know the default program to open the .nbh files
 

I messed up and changed the default program to open .nbh file and i think that could be the reason i cant sd flash a radio so im trying to change it back.

There is no default program for "opening" an NBH file. It's not a file that can be opened, and Windows has no clue what it is by default. You just need an RUU to flash it, or flash from SD card. But there's no program to simply open it or default Windows association.

EDIT: I see you mention SD flashing. Are you talking about default file association in Windows, or Windows Mobile? If you mean Windows, there's absolutely no connection between Windows and your phone when it comes to SD flashing. If you mean Windows Mobile... well, when you enter the bootloader (Power+Camera+Soft Reset Key), Windows Mobile's no longer in the house either and has nothing to do with that file, so that wouldn't matter, either. Is your card a non-SDHC card formatted FAT32 with the file named TITAIMG.nbh in the root of the card (not in any folders)?
