@suikoden - Please link stock BIOS used, and upload your modified BIOS, maybe modified BIOS is faulty.
You already checked this via hex - Flashing Gigabyte while avoiding "Invalid BIOS image" (4)

You can rename your file anything you want, but FX or F5 or Bin or rom etc, all = the same to Gigabyte flash tools (Qflash recommended)
AFU is not recommended at all for flashing modified or stock Gigabyte BIOS, it's never needed

Flash stock BIOS to your board using Qflash of the version you modified, then Qflash the mod BIOS.
I doubt ID is wrong, are you sure you have the correct BIOS per your board revision and model? It's possible, but not likely.

Hi Lost_N_BIOS,
I have to correct myself i already have the latest stock BIOS (F24) and there appears to be something wrong with it because I can not flash any BIOS anymore, it doesn't matter what I'm trying to install.
Modded Efiflash doesn't seem to help either.
In another thread I found someone having the same issue as me and fixing the OEMID worked for them, I just don't know how to do that.
Thank you

@suikoden - if you are 100% sure, I can fix for you, but it's risky to flash if you don't have BIOS switches on that board or a flash programmer.
Show me CPU-z Motherboard tab and BIOS image showing System Info (F7 or F9 I think, I believe this shows current BIOS ID)
Can you flash back to F23, if not, try doing it with @BIOS

#79 RE: Flashing Gigabyte while avoiding "Invalid BIOS image" by suikoden 16.01.2019 21:31

Thank you so much, getting the info real quick and will edit it in.
EDIT: I can not flash down to any BIOS. Sorry for the blurry system information.

@suikoden - did you try to downflash to F23 using @BIOS, or F24 linked below? Also, please test flashing stock F23 and F24 via Qflash from within the BIOS itself
Is that motherboard name the exact one printed on your PCB/Motherboard itself? Do you only see OEMID error with @BIOS, or where are you seeing that, with stock BIOS?

Please try with @BIOS to flash latest official F24, you may need to install "App Center" first before you can install @BIOS

http://download.gigabyte.us/FileList/Uti..._B18.0517.1.zip

That F24c is beta BIOS, not stock official. Latest (and newer than F24c) is F24 final
http://download.gigabyte.cn/FileList/BIO...0m-ds3h_f24.zip

BIOS ID is correct in your BIOS vs F23/F24/F24c, and OEMID is normally a ME flashing FW thing, which you are not trying to do. Please show me where/with what you get this OEMID error.

Flash ID is same across all three as well


Do you have flash programmer?

#81 RE: Flashing Gigabyte while avoiding "Invalid BIOS image" by suikoden 18.01.2019 20:40

@Lost_N_BIOS I tried downgrading using @BIOS, will try via QFlash now.
Will edit post once I've tried.
I don't have flash programmer.

What did @BIOS tell you when you tried F23 or F24 I linked above?

Order flash programmer now and SOIC8 test clip cable if BIOS soldered to board, that way they'll arrive soon and you can fix BIOS easily to whatever you want. These are cheap, less than $6 total shipped on ebay for both (CH341A + SOIC8 test clip cable), let me know if you need links.

#83 RE: Flashing Gigabyte while avoiding "Invalid BIOS image" by suikoden 18.01.2019 20:59

It was "Invalid BIOS image". It finally worked though. Seems like I needed to downgrade just one BIOS to get it to work.
I am on F23 now do you think I can flash to the attached BIOS now?

@suikoden - Great you got it! I would use only F24 now, not the beta F24c. What is the file attached, what did you mod etc? It's F22b BIOS, why are you using that one now??
I checked one thing, it needs an edit at offset 0x00e6dfff >> Change 01 to 00, then you can flash this BIOS via Qflash.

#85 RE: Flashing Gigabyte while avoiding "Invalid BIOS image" by suikoden 18.01.2019 21:15

@Lost_N_BIOS thank you so much. I've got this file from someone else, because it seemed so difficult to do it.
I will try modding the F24.
Do you by any chance know which button to press for Qflash? My Bios resolution is very off and I can't read it.
Forgot to mention. Seems Gigabyte even removed the download link to 24c too now.

@suikoden - F8 is Qflash hotkey If you need modified F24 let me know, and let me know what mods you need done to it.
That F22b you linked, if it was modified by someone, cannot be flashed via Qflash until you edit it via hex at the address I mentioned above, without that change you will get "Invalid BIOS Image" message

There, below, is download link to F24c, however I suggest you use final F24 >> http://download.gigabyte.cn/FileList/BIO...0m-ds3h_f24.zip

#87 RE: Flashing Gigabyte while avoiding "Invalid BIOS image" by suikoden 18.01.2019 22:09

@Lost_N_BIOS can one copy the mods from the modded F22b to the F24 or is that not possible?
- unlocked Precision Boost Overdrive Scalar (feature of 470th motherboards for zen +)
- SOC OVERCLOCK VID (feature of 470th motherboards for zen +)
- unlocked AMD_CBS + sub menu
- unlocked additional DRAM parameters
- unlocked VDDP voltage
- disabled HPET & Spread Spectrum
- BCLK frequency stabilization
- improving the overclocking potential DRAM
- unlocked modes NX, PSS, CPB, C6 and others
and unlocking other "sweet features" is what this supposed mod does.
Thank you again, you can not believe how grateful I am.

Yes, I can do that probably, but it will take some time to do. You're welcome, I will try to get this done tonight for you.
Is that @ket 's mod BIOS F22b?

#89 RE: Flashing Gigabyte while avoiding "Invalid BIOS image" by suikoden 18.01.2019 22:25

@Lost_N_BIOS, thank you, that's very kind of you.
It's from some user on another forum. Does ket have a modded BIOS for this motherboard?

@suikoden - I'm not sure if he does or not, that change log you provided reminded me of something he might say so I thought maybe it was his.
I checked, and yes, @ket has this AX370 mod BIOS thread, where he did many board variants and maybe in that thread he did a one-off BIOS for someone or a few people using same fixes?
[OFFER] Gigabyte GA-AX370-Aorus Gaming 5 BIOS mod

* Edit - Sorry, there is too many changes between F22b and F24 for me to safely transfer those modifications (There is added settings and increased file sizes) I have made a mod file with directly transferred modules, but it wouldn't be safe for you to test without a programmer.
And I went to manually transfer changes (in 4 modules), but due to new settings/options added and increased file sizes, I can't do that blindly either (via hex is how I would do this, since changes are made in that manner and not via software/GUI)
You'll have to ask the user who did the F22b mod to make new mod to F24, or use stock F24 or go back to F22b
