Flashing Gigabyte while avoiding "Invalid BIOS image"

Intel are now killing off any kind of legacy booting, therefore 11th gen upwards breaks legacy booting completely, there will be no legacy BIOS compatible motherboards or graphics cards from any manufacturer, this means FREEDOS or Any other type of Dos WILL NOT work, in turn forcing people to flash modified uefi’s from within windows (at an extremely high risk)

The pc will still boot to setup using CSM (cant see the point in this) however Dos based flashing tools of any sort will never work, the original IBM compatible Bios as we know it has gone forever. Next manufacturers will encode UEFI files with encryption/high level protection in the end making it impossible to do, and will only be possible via windows update.

Intel and AMD made it pointless to overclock, now theyre going to make it impossible to flash custom firmwares, i am beginning to realise that owning a modern PC is going to be a very boring experience in the near future. And then theres the fact that windows10 and 11 are both completely crap (which all modern pc’s are stuck with) until these companies start to cummunicate more with the end users and give them what they want, the humble PC will end up being killed off.

Apple have now made laptops that are on par/faster than desktop systems fitted with RTX 3080’s which means the tables are going to turn around big time, making apple the new mainstream number 1

Im getting sick and tired of all the antics computer companies are coming up with now, theyre on a mission to lock down computers so much until in the end it will be pointless for enthusiasts to even own one. im to the point now that i would rather use an old 2015 macbook air, especially with great emulators like OpenEMU (which is better than anything on windows)

My next computer purchase will be a desktop Mac Pro, then i wont have to deal with all these stupid problems, you think macOS is locked down? yea well ive never had any virus of any kind on any of my macs, plus the OS itself is 10x better than anything microsoft have ever made. Windows has more bugs than those found in Madonnas knickers.

Yes my friends, the modern PC as we know it has turned to shit.

Its a scientific fact, if you introduce something slowly enough you can get away with anything.

No one knows how to force flash AMD-RYZEN gigabyte motherboard? mine says “BIOS is protected by SecureFlash” and i can’t flash it… FPT is for intel, i need an RYZEN compatible flasher… pls help :frowning:

@ket has the modified bios flasher on his X370 GAMING5 page

The conversion pack I made might not even work in this case but you can find it here; [OFFER] Gigabyte GA-AX370-Aorus Gaming 5 BIOS mod

Hey I can’t get to download [FPT_v12.0.x.zip] I have been clicking on it and nothing happens

You rely more on user links than the forum own links to tools?
How about using the search box on the forum… it works you know.
Start reading


And stop posting every where, new posts users will notice.

EDIT: Read it some where in this thread is the solution to your issue (Not my time to lose) and get the tools package from link provided earlier.

I am still very confused man and I apologize I am new to this forums thing. I have a Z390 Aorus elite if you can help me out somehow, I would appreciate it : )

Hi there, is there any way to flash modded bios on gigabyte motherboard? Im using b450 auros m and when i try to flash bios using efiflash i got “BIOS is protected by SecureFlash” and i cant flash it, mobo is on the lastest bios. Can someone help me?

You cant flash with the moddet efiflash 0.87 the new capsules Bios. You need this tool…[Tool] Flashrom v1.2 [DOS] [AMD] …it works perfect with gigabyte ga-ax370m-ds3h. I think i helps many people.

Thank you for replay, i managed to flash it, first i needed to flash old bios, then i could flash modded one. Work just fine.

Hi. I try this but i cannot modable bios update. Can you help me please? I can talk on discord if you don’t mind.

@Femboy Here is the new link and thanks for bringing the broken link to my attention.


@mixeray u got z390 gaming x ? i got same problem i need help

@2625055 Hi, you pm’d me about needing help - what do you need help with specifically?

One what i need is only downgrade any posible way from F10 Bios at Gigabyte Z390 Gaming X Rev 1.0. Cause i wanna go back to old version, working better is one and other i got moded bios by Lost_In_Bios F10A version.

Please explain me how to downgrade this i saw post u helped with that for someone and he type he got like Z390 gigabyte GX what mean Gaming x i think so that’s propably same board

@2625055 I wrote a guide here that describes how to downgrade from Gigabyte capsule BIOS that will work with your motherboard.

yea but what method 1 2 or 3 should i use ? i am rlly lost in that. Maybe litle help it’s black magic for me.

@2625055 Method 1 is the easiest as it can be done from Windows.

Just make sure to write your MAC address down somewhere before you attempt to flash the older BIOS as your board has an Intel ethernet adapter and it will get overwritten (erased) by FPT if you forget to ue the -savemac command.
