    Exclamation Any help in dowgrading a GM501GM from BIOS 308? EZ flash and Winflash dont help.

    Ive encountered Issues with my laptop, used to run new games at max settings but ive noticed after updating to bios 308 ive had a massive performance downgrade, and cant seem to be able to upgrade or downgrade in EZ flash 3, it says "Selected File is not a proper BIOS" Ive gone to Asus Support with no much help at all. Any help is appreciated.

    I have not had any trouble downgrading/upgrading the bios on my GU501GM.

    -Download the bios file from the Asus support site
    -Unzip the folder and put the contents on a thumb drive
    -Reboot the system and access the bios
    -Access the flash utility
    -Navigate to the thumb drive containing your desired bios and load it

    Make sure you have the correct bios file

    Actually after looking there is a v.309 and v.310 bios file on the support site, you might do better upgrading to the latest version than downgrading to a previous one.
