Flashing Gigabyte while avoiding "Invalid BIOS image"

@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.

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.
