Downgrading UEFI to Awardbios on Gigabyte Z68

[Rogue26]

Made the mistake of upgrading the bios on my GA-Z68X-UD3H Rev 1.3 from F12 to UEFI and now I am unable to boot without KP. I posted a thread in desktops and it was suggested that I revert back to the F12 but I am not having any luck downgrading. I have found a thread here: https://www.techpowerup.com/forums/...uefi-to-previous-hybrid-bios-gigabyte.168667/

With some directions but it looks like you need a bootable windows OS. Does anyone know a method to downgrade using a bootable USB drive? I have a windows laptop but no other access to OS X any suggestions would be much appreciated. Pictures of boot attempt are attached.

Thanks

Using the files provided at the above link I was able to revert the bios back to F12. It appears as though the flasher can be used in a win, win64, or DOS. I didn't realize that it could be used in DOS so I set up an old drive with a windows 7 but I think I could have don't it using a bootable USB stick.
