I have an UD4 rev 1.0 with F3 BIOS but when I try to flash something newer like F7, it will say the file is invalid?? I am flashing from BIOS with F8 to go to EZFlash.

What's the problem? It's the correct BIOS :s

Edit: seems I need to flash in dos or windows so ezflash gets updated for newest bios. Will try tonight
