Hi Serg008, Can you please also help mod this Gigabyte bios? Many thanks again in advance! Gigabyte B460M-DS3H
try with AMI APTIO V afuwin or afuwingui - flash MAIN block only! (use /P option) add. when the same error occurs ("Secure Flash Check Fail"), the Mod must be flashed with SPI flash programmer (as here https://forums.mydigitallife.net/threads/award-ami-bios-mod-requests.5863/page-3116#post-1475389 )
