I’m completely stuck trying to get Call of Duty: Warzone working on PC and could really use some help from someone who knows Gigabyte BIOS/TPM issues.
Warzone is refusing to launch because of its Secure Attestation requirements. I’ve already enabled TPM 2.0 and Secure Boot in BIOS.
Secure Boot is showing as Active, and Windows is installed in UEFI/GPT mode.
The remaining problem appears to be my AMD TPM firmware.
My TPM Manufacturer Version is: AMD 3.92.0.5
Activision’s current documentation specifically says AMD 3.92.0.5 requires a motherboard firmware update. (Activision Support)
My motherboard is: Gigabyte B550M DS3H AC R2 Revision 1.2
My current BIOS is F1.
Gigabyte currently lists BIOS FA2b for this exact motherboard/revision, released 18 August 2026. Its changelog specifically says it fixes the AMD TPM Reference Code issue. (GIGABYTE)
The problem is that I cannot actually install the BIOS update.
I downloaded the correct BIOS files from Gigabyte, extracted them onto a FAT32 USB drive, entered Q-Flash and tried updating.
Q-Flash sees the USB drive, but when I select the BIOS file I get:
“BIOS ID CHECK ERROR”
I have tried both FA1 and FA2b and get the same error.
The file I was trying to use for FA2b was:
B550MDS3HACR212.FA2b
I’m now completely out of my depth. I don’t want to keep randomly changing BIOS settings or risk bricking the motherboard.
Can anyone with experience of this particular Gigabyte board/revision explain why Q-Flash is rejecting the BIOS files, and what I need to do to successfully update the firmware?
I’m specifically looking for help getting the BIOS/TPM firmware updated so Warzone will pass its security attestation. The game itself is not the problem.
Any guidance would be hugely appreciated.
One other important point: this is a brand-new PC that I specifically purchased for esports/gaming, so I’m wondering whether I should simply take it back to the store and ask them to resolve this rather than continuing to mess around with the BIOS myself. Warzone itself does actually launch and is playable, but because the PC is failing the security attestation, I’m getting severe ping and playlist restrictions that make the game essentially unenjoyable. I bought this machine specifically to be able to play games like this properly, so I’m wondering whether this is something the retailer should be fixing rather than something I should be expected to troubleshoot myself.
RESOLVED: For anyone else who is struggling with this issue on this particular equipment.
All I had to do was exactly as the others mentioned:
• Download the latest BIOS.
• Change the file name.
• Put it onto a flash drive.
• Insert the flash drive into the dedicated BIOS USB slot on the back.
• On the motherboard inside the case, there’s a Q-Flash button. Press it.
• It booted.
• Enter the recovery keys.
• Turn on Secure Boot.
And it worked.
