try flashing with Instant Flash from Bios. Flash original one, after reboot - Default settings, thеn flash modded bios.
I did try it with that name. The problem is not the name of the file. Instant flash seems to scan the file for something that no longer exists in the modded file. When instant flash scans the file it prints out some jibberish that it found in the file where it was probably expecting something.
