Wrong firmware install

Hi i have look around these forums but i don’t know what to look for.

Help needed bad!!! I had a NEC ND-2500A DVD and i was having problems with it so i ask my mate if he knows how to fix it and he said yeah try this new firmware so i install it and it ask me to restart after so i did, after the computer reboot the NEC ND-2500A DVD drive turned to FREECOM_DVD+/-RW8B, so doe’s anyone know how to get my NEC ND-2500A DVD drive back to its original state as i think i install the wrong firmware?

Thanks for any help?
