Gigabyte BIOS update issue

[smelanson]

It has been a while since I posted here but I was curious if anyone has experienced this issue with a Gigabyte motherboard. I have a B460M DS3H with BIOS version F5, I updated it from F3, there are not 2 new updates, F6e and F6. I am unable to update to either of them, I receive the message “Invalid BIOS image” in the Q-Flash utility. I have downloaded the file multiple times on different computers, etc and still have the same issue. I am thinking about resetting the BIOS settings. I contacted Gigabyte and they said I can send it back under warranty but I don’t want to be without this system as it is my file server. If anyone knows of a solution please let me know.

go to gigabyte-forum and get a replament MOBO. Always good to have multiples at hand. and be aware. after certain time psu, videocard must be replaced. psu better before crashing pc.
and cleaning all contacts from time to time. if sata-drive also those under board!! no need to explain why. have almost 30 years of experience. and doing that saved me often.
I would have googled the problem

UPDATE TO F6

READ ALL COMMENTS IN BIOS-UPDATES!!! ALWAYS

If the motherboard works, I would advise leaving it. You risk bricking it if you fail. If everything is working, don't "fix it", unless there is a feature you require or you must upgrade the CPU.

I have the Gigabyte B460M motherboard and used a newer Efiflash version to allow updating from F5 (did you mean F6b?).
The Efiflash version included in the F5 bios for this motherboard would not work with later bios versions.
Neither would the Q-Flash utility on F5.

I used Rufus on Windows to create a bootable USB drive with DOS selected under Boot selection.
You might also be able to select FreeDOS.
I then copied the Efiflash v0.98 for DOS over to the USB drive, along with the bios firmware.

I went from F5 to F6b version.
I then went from F6b to F6 using Q-Flash.

I chose to flash the main and backup bios, but it is probably a good idea to wait to do this until after you have a successful flashed and booted only one bios.
I then loaded default settings in bios menu.

You can find a collection of Efiflash utility on the July 3, 2023 post here:

In this particular case, it might be wise to update especially if running Windows:

I tried to provide instructions that worked in another post.
