Besides a try out with Intel ME FPTtool, a cheap CH341 would be a must as the system can be broken...or not.
Easier in the V3 than V2 as this one is WSON SOIC8 surface soldered and the regular clip for SOIC8 wont work here.
Wot method gave u the mismatch, q-flah or flashefi?
Heres a mod EFIflash tha u can try and read a bit the thread: Flashing Gigabyte while avoiding "Invalid BIOS image" (18)

Usage:
EFIFLASH [Input or Output File Name] [Command]

Commands:
/Q - [Q]uiet mode. Don't ask for key pressing. (Secure Flash)
/DB - Update both Main & Backup BIOS for DualBIOS System
/R - Reboot System after BIOS Update
/C - Clear DMI Data
/S - Save ROM image to file

Bypass:
!!! BIOS ID Mismatch !!!
!!! OEMID Mismatch !!!
!! Invalid BIOS image !!
The current BIOS image is outdated.

EDIT: The motherboard will boot to any USB depending how it was made, to boot legacy (CSM ON/AUTO) or uefi (CSM OFF).
On shared link thread theres plenty of EFIflash mod files versions and info on USB preps. Or make a post there explaining ur problem.

Donations via PAYPAL / REVOLUT, if u think the guy deserves it, else to the Win-Raid community on the bottom of the page, as it deserves for all the gathered information.
