Hallo, bei mir war eine sehr alte Version drauf. Q-Flash Plus ohne CPU hat bei mir geklappt. Hier die Anleitung:

Q-Flash Plus allows you to flash a working BIOs even your computer won't boot. It doesn’t even need a CPU or RAM to be installed!

The steps to utilizing Q-Flash Plus is very simple. Should your computer fail to boot, follow these steps.
Step 1: Prepare the USB drive (FAT32)

Download the latest BIOS version for your motherboard from the motherboard product page. Extract the downloaded BIOS file to the root of your flash drive. We need to rename the BIOS file so that Q-Flash Plus can find it. Rename the BIOS file to GIGABYTE.bin.
Step 2: Plug the USB drive into your computer

Now you need to plug the USB drive into the USB port that supports Q-Flash Plus. You will be able to find this in the manual of your motherboard.

Q-Flash Plus allows you to update the BIOS when your system is off (S5 shutdown state). Save the latest
BIOS on a USB thumb drive and plug it into the Q-Flash Plus port, and then you can now flash the BIOS
automatically by simply pressing the Q-Flash Plus button. The QFLED will flash when the BIOS matching
and flashing activities start and will stop flashing when the main BIOS flashing is complete.
