@thinking - It's OK, thanks for stopping back in! I already have eeupdate, don't need that.
I was asking for you to send me DuelEFI tool, you discussed here at post #35 - Gigabyte GA-Z97X-UD5H-BK BIOS upgrade (3)

@Lost_N_BIOS
I'm sorry I got it wrong. I'll fix it right away.
A few months ago, it became slower and slower to visit this website, so I didn't go to it every day.

Another primary and secondary BIOS converter SWITCHN.exe
Using this in DOS only, you can switch between the main BIOS and the backup BIOS. (It may only support the old motherboard without UEFI function and DUALEFI.exe support new motherboard with UEFI .)

@thinking - Thank you! Is the site still slow for you? If yes, do you think it's our site, or due to your country firewall?

@Lost_N_BIOS
Now I have to get used to this kind of network environment. At present, it's not bad.
The most pleasant thing is that I can get to know many experts on this website, you, SoniX, and webmaster plutomaniac.........

@thinking - Yes, please stick around and hang out with us more often, when you can
Do you edit BIOS too?

@Lost_N_BIOS
Oh, no, I'm not as good at editing BIOS as you are, but I'm the beneficiary of you masters, so I'm also willing to share good methods, good software, and contribute to the forum.

It's amazing. My MAIN BIOS it's unbricked. I flash it with Efiflash to the f31 and in booted well. This was not the surprise. Then I turn off the PC unplugged the power, a minute later plug it back and I turn it on and unbelievaly it booted (since unpluging the power will force the motherboad to boot on the MAIN insted of the BACKUP) considering that if I did this before it won't even boot anything. So I'm now running in my MAIN BIOS !!! And I can't worry about the power turning off and starting the PC with the backup reseting everything in the BIOS. Incredible. Thanks. Now, my question is, it's worth to upgrade the BIOS to the f51? Or I should keep mine in the F31? The F51 brings something new or good for my PC? I have a Ryzen 1700 btw. Well I can't express more apreciation for this. Thanks and sorry for this butchered english.

Hi

Really appreciate all the work you have done here. I was wondering if you can assist me in the right direction. I have an OEM x470 mobo where when I try to update the bios I get the "oemid mismatch" error as it says above. Which version out of the 4 efiflash tools do I need to use to update to the latest firmware?

I just want to make sure I do it right and use the correct one as to get around the OEM restrictions of not being able to update the BIOS.

Am I correct in thinking it is the Efiflash_v0.85_mod?

I basically just want to overwrite there bios.

Any help would be muchly appreciated

Many thanks

@dom191984 Hi, I would try Efiflash_v0.85_mod first (after making a complete backup of the original BIOS) and if that doesn't work try Efiflash_v0.80_mod.

@chinobino

Ok great. and when I run the mod in MS-Dos will it be this address line C:/efiflash X470AOUG.F51 /x

@dom191984 You can just use;

efiflash X470AOUG.F51

@chinobino

Many thanks for this.

Sorry one other thing. Do I change the name of the mod just to efiflash?

@dom191984 You can name it whatever you want.

@chinobino

All done and worked like a charm. You are a legend for this. Really happy :)
