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.
