How to downgrade UEFI to previous Hybrid Bios - Gigabyte

[brandonwh64]

*Disclaimer*
This may or may not work for your board and also MAY work for other board manufacturers but YMMV and I hold no responsibility if it bricks your board. AMIBIOS is what most gigabyte boards use.

Ok after a near crap experience tonight of wanting to test out gigabytes new UEFI bios for some Z68/P67 boards I wanted to go back to the regular bios. The new UEFI bios was nice but was missing things for OC like LLC, PLL overvolt, and offset voltages. The following steps I had gotten off My Digital Life.

1. First thing is to goto gigabyte and download the older bios you want
2. Next is to download the utility above (If link is dead PM me I will upload it for you)
3. After downloading, extract and find the version for your OS (Win or Win64)
4. Copy the folder to the root directory of your hard drive ( C:\ )
5. Extract your bios to this folder as well that you have copied to the root directory of your hard drive
6. Your bios should look like this "Z68XUD3H.F12" what you need to do is rename it to "1.rom"
7. Now goto CMD prompt and type without quotes "fptw.exe -f 1.rom" or "fptw64.exe -f 1.rom" whichever OS you have
8. Let it flash (takes like 2 minutes). Once its completes turn the PC all the way off and cycle power. At this point its fingers crossed to see if it made it.

TIP* this way of blind flashing only flashes the first bios so it is best that once you get back into the bios, run Qflash and reflash the bios you want so it does both bioses for safety.

Just had a PM about this thread, Its quite helpful to those with the later gigabyte Z68 boards that got the transformation bios and does not like it.

Big thanks for bumping this as I tried to but it wouldn't let me as the thread was older than 145 days

I am going to try this now as I have the GA-Z68X-UD3H-B3 board and the UF1 uefi bios is buggy as hell, conclusion to come (or if it doesn't and I don't post for a while my board is toast )

Edit: Brandon can you upload the utlity to TPU instead of having to use that crapware download manager in the op?

I would but I am at work and my work blocks mediafire.com
Once I get home I will upload for you guys.

Did you download it from the links you posted and with their "download manager"? I will install it if needs must though would rather know it is safe and shitware free before installing it to download the utility

UPDATE FOR WIN 7 X64

Thanks to brandonwh64 for this guide however I had to tweak it slightly for Windows 7 x64 as follows:




1. First thing is to goto gigabyte and download the older bios you want
2. Next is to download the utility above (If link is dead PM me I will upload it for you)
3. After downloading, extract and find the version for your OS (Win64 for Windows 7 x64)
4. Copy the contents of the folder to C:\Windows\System 32
5. Extract your bios to C:\Windows\System 32 folder also
6. Your bios should look like this "Z68XUD3H.F12" what you need to do is rename it to "1.rom"
7. Now search for CMD prompt from the start menu and right click to run as administrator then type without quotes "fptw64.exe -f 1.rom"
8. Let it flash (takes like 2 minutes). Once its completes turn the PC all the way off and cycle power. At this point its fingers crossed to see if it made it.

Did this method work for you? Also I uploaded the Zip to the OP now using my phone!

It did when I changed the steps as outlined, also be sure to download the same bios you flash on to a USB drive then run the bios Qflash utility to flash the "dual" bios after you flash in Windows, as the method you posted only flashes the "main" bios.

Though now i have succesfully downgraded from uefi and I couldn't be happier as my stable 24/7 OC became unstable with the uefi bios and Gigabyte offered no way to downgrade to legacy

BTW all the kudos goes to you for the guide I just tweaked it though couldn't have done it without the OP
