I downloaded the wrong bios from google (Sharp Technologies) and now i cant use my PC

So i downloaded and installed the wrong bios from searching on google instead of going to Gigabyte¨s site and now im paying the price. I have a PC thats unwilling to boot up as it can no longer find / recognize my SSD as a boot drive and neither can i select any of my drives.

Ive put the latest version of bios (and tried older ones as well) on a USB stick & Q-Flash to try to install the correct version of the bios but all im getting no matter which version i try is (OemId Mismatch)

Before anyone links to a similar thread, ive already tried to make a bootable USB stick with Rufus to no avail. DOS is apparently not supported as a boot option for this MB.

Any help highly appreciated as i wont be able to use this computer unless something is done.

MB Name: X570 Gaming X
