How to update Gigabyte UEFI Bios

[Gamer1234567]

I need to update my bios. If I dont my cpu runs really hot (new update has apu support). I have tried q-flash @bios, and other methods. None of them work. When I try to use a usb stick to q-flash, it says "Bios id check error", i have looked all over google and there isnt a fix. Thanks.
My mobo: Gigabyte F2A88X-D3H

when you download the new f5 beta bios it an exe file. you have to run it and unzip the file. then on a fat 32 formated usb stick put the unzip bios file on the stick and then boot with the usb stick in the usb 2.0 port and see if it reads it.

I have done all of that already it still gives me "Bios id Check Error"

Gigabyte BIOS files come in the form of an .exe file. This is a compressed file that includes a Self-Extractor. Run the .exe file to unpack the file to your USB thumb drive.

Did you read this Note:
Note: To support FM2+ APUs, be sure to use an FM2 APU to update the BIOS to the latest version with the EFI Flash tool included in the zip file. (For a future BIOS upgrade, you can use either the Q-Flash or the EFI Flash tool. )

Heres what i do. I download the gigabyte f3 bios, i extract it to a folder on my desktop. Then I copy the files to a usb. Next I enter bios and go into q-flash, i choose my drive and the f2a88x file, it says BIOS id Check error.
Also I tried to use the Efiflash.exe and its says "this app cannot run on your pc".
When i try to run the autoexe.bat, it says this


Unsupported 16-Bit Application

The program or feature "-------------\Efiflash.exe" cannot start or run due to incompatibity with 64-bit versions of Windows. Please contact the software vendor to ask if a 64-bit Windows compatible version is available.

Please help me Im having trouble with this, I might just be missing something really simple.

In the link above you use the VERSION 2 DOS instructions.
Basically, you make a USB thumb drive bootable into DOS. DOS is a operating system. The EFI Flash tool and the BIOS file are on the USB Drive. When you boot up into DOS it will run the EFI Flash tool automatically.
