I am running the moddified f23 from you and i can access the afuefix64 command and everything else but i can not access the bios image from inside the dos boot up. I will try with the updated efi files tonight, however I’ve had no luck so far I’ve even tried 1usmus’s version of the efi archive and also tried afudos version as well. All the bios I’ve tried so far have been inaccessible from the dos command line. All bios and even reading the stock bios info to check the romid with afuefix64 gives the same error 46 error unable to access flash info. I’m gonna keep troubleshooting tonight
Obvious as it is, I take it you have placed the firmware images in EFI > BOOT?
Yes and I can see the rom file in the boot directory from dos with the "ls" command.
So I downloaded the newest afudos from the link you gave and tried it. Its saying my bios is write protected even Leaving out the /b command. I’m stumped
This is magical. now both bios are starting to corrupt. Was trying to get the bios to flash from the dos instance and shut it off and switched to bios b. (I run in single bios mode, to reduce the chance of this happening:/ )boot it up and its displaying the bios in 188p or something like it has in the past. I shut it down flip back to bios a and boot and its doing the same thing:/…wtf and attempts to reflash with qflash fail to bring the resolution back. Fuck think I might have almost bricked my board.
Edit: and now its fine. I desperately need to figure out how to get this flashed through dos.
Flash from DOS using standard Gigabyte EFIFlash utility, add the /x or /z switch if it gives you grief. If that fails use Qflash (Suggested), I don’t understand the issue aside from trying to use AFU when there is other easier methods listed before AFU in ket’s instructions
Do you need help creating a DOS bootable USB, without RUFUS? If yes, use this method - <Request> Flagship X470 Gaming 7 Wifi Motherboard BIOS Fix
Ignore the EFIFlash if included in above linked download, I can’t remember what board it was for but certainly not this one, use the standard one that comes with your BIOS.
The issue I’m having is bios f23 has a tendency to corrupt the bios image. Its generally assumed this is happening because previous bios and settings are not being properly deleted. This is Also effecting my stability and just general ability to use my board as intended. Ket suggested the use of his in depth method to completely clean the chips of old images.
The issue is that my bios is also apparently write protected or something. Because all attempts to flash in DOS have given an error code of unable to access flash info or bios is write protected. So far I have tried kets method, 1usmus’s method(ryzn dram calc) and several different versions of afudos. All attempts (even attempts to flash without clearing the chips first) has given these 2 errors. Unable to access flash information, or bios is write protected.
I have also tried using both Rufus and the HP tool as well. Both results are the same.
Fuck it off, put it on ebay fella before its too late, they are shite, if you stick with any x370 gigabyte board you will be spending most of your time trying to fix problems than playing games. Or worse still wondering if it will boot the next time you switch it on. This thread proves it, 66 pages later and they still dont work properly.
Flash from DOS then using EFIFlash with the /X or /Z switch, it will erase the chip before writing, so does Qflash except for LAN MAC ID.
Set BIOS to single mode and keep there for now, once flashed and all setup you can enable double again and reflash backup chip to match main and then disable again to run on single BIOS only, that should help.
I only suggested the HP tool to make a bootable DOS stick, so you could use EFIFlash, AFU I never have luck with either and it has it’s own issues aside from these so I always suggest some other method whenever possible.
I’ll give it a try tonight and report back. I’m actually planning a switch to itx and sffc with zen2. I just need this board to last till I can get a decent x570 itx board lol.
Oh and for the record theres yet another problem with these boards, they suffer badly from microstutter, half way through playing a game or watching a video, BRRRR BRRRRR BRRRRR then crash.
Their b450 itx boards are actually pretty bloody good mate! its just their x370 variants are piss poor
mini itx forces gigabyte to put the m.2 slot in the correct place, near the cpu, less latency and easy to change when watercooled, winner winner chicken dinner.

@ket will you be releasing any more modded versions?
There is a single report that F24e on X370 K7 is shoving excessive voltage into CPU on any settings other than auto.
Single reply from me but no not here , normal voltage readings on auto 1.35…V ~ 1.4…V
Seems the Agesa has a few upside thumbs (so thats positive)
But a few glitches from GB (as always) fans set nr1 and adopt settings to all fans 2,3,4 and/not pump 5,6 then check fan3 offsets 3 and 4 are not where they should be
fix that and oyes its now on fan4 ( kinda enoying fix that and i didnt have pump 5,6 set so it was ok even after resets seems a 1 timer)
Still the voltage glitch on Vsoc exists set it to 1.031…V and after a windows restart or just bios reboot and it sticks to 1.1…V
But time will tell if its the long awaited "gb is on the move at the right way with the steeringwheel on the left" 
My 2700x is zipping along at 4.325Ghz 3466ram cas 14,13,11,11, intel burntest gives 238.8Gflops max temp 80c 28c idle on my x470 gaming7 wifi and theres still more room to go
my mates x370 k7 cant manage 4ghz with my 2700x with 3200 ram, max intel burntest 201.1Gflops 3.98Ghz max temp 91c, 34c idle
basically you are losing the performance equivilent of a core2duo E8600 @ 4.25GHz
ive tested my cpu in his board with identical cooling, so this speaks for itself, x370 is weak on gigabyte boards, why are you even wasting your time with this shit. even the biostar x370 boards are better than this ffs
2600X 4.25GHz 1.39V + Ripjaws V 3333 CL14 = great performance on my GA-AX370-Gaming-5
2600x yea but thats only a 6 core cpu, it cant handle the 2700x
