Omen Max 16 (RTX 5080) - TPM Measured Boot logs causing Ricochet Anti-Cheat Attestation Error in War

[MMA171]

Hello everyone,

I am opening this thread to request an urgent update regarding a known BIOS firmware issue that is completely blocking access to certain games on high-end Omen devices.

I currently own an HP Omen Max 16 with an RTX 5080, running the latest available BIOS (version F.22). Currently, I am entirely unable to play Ranked matches in Call of Duty: Warzone. The game’s anti-cheat engine (Ricochet) kicks me out with an attestation error.

To be clear, my system is fully compliant with standard Windows 11 requirements:

 TPM 2.0 is enabled and active.

 Secure Boot is enabled.

After doing some extensive research, the root cause is not on Activision's end, but rather a flaw in how the current HP BIOS handles the TPM Measured Boot logs. The logs are either failing validation or not being generated correctly, causing strict anti-cheat systems to flag the PC as untrusted.

This is incredibly frustrating for a high end gaming machine. The latest BIOS completely ignores TPM log issue.

Could the HP engineering team provide an official ETA on a new BIOS update that actually patches the TPM Measured Boot logs? Several users are stuck in the exact same situation and we need a real firmware fix, not a workaround.

Thank you,

Mateo

Same here on my Omen Max.  Passes wizard and everything is up to date.

Filed a ticket to Activision (through using the game does not install help topic, fyi), sent them videos and all the info.

Their reply after all of that, "We are aware of the situation and do not have timing on a solution" - note did not copy that so it might not 100% match.

Now we just have too patiently wait, and file complaints.

Bios update released 8/18/2026 (version F.23) has resolved this issue on my Omen MAX

Hello ,

I am opening this thread to request an urgent update regarding a known BIOS firmware issue that is completely blocking access to certain games on high-end OMEN devices.

I currently own an HP OMEN Max 16 with an RTX 5080, running BIOS version F.22. I am currently unable to play Ranked matches in Call of Duty: Warzone. The game's anti-cheat system, RICOCHET, kicks me out with an attestation error.

My system meets the standard Windows 11 security requirements:

- TPM 2.0 is enabled and active.
- Secure Boot is enabled.
- Windows 11 is fully updated.

After investigating the issue, it appears that the problem may be related to how the current HP BIOS handles TPM Measured Boot logs. The TPM PCR values and TCG Measured Boot log may not match correctly, causing the system to fail remote attestation.

This appears to be a firmware/BIOS issue rather than a Windows configuration problem. Strict anti-cheat systems such as RICOCHET rely on hardware-backed attestation, so a problem with the BIOS-generated TPM measurements can prevent the system from being recognized as trusted.

This is extremely frustrating on a high-end gaming machine.

Could HP please provide an official update regarding the BIOS fix for the TPM Measured Boot/remote attestation issue?

Specifically:

1. Is HP aware of the TPM Measured Boot/PCR mismatch affecting OMEN Max 16 systems?
2. Is a BIOS fix available or currently being developed?
3. Which BIOS version contains the fix?
4. Is there an expected release date for the corrected BIOS?
5. Are there any recommended temporary workarounds that do not require disabling TPM or Secure Boot?

Several users appear to be experiencing the same problem, so an official response and firmware fix would be greatly appreciated.

Thank you.

Hi @wpzone3263,

Thank you for your patience, 

We know this isn't the answer many customers were hoping for.

Our engineers' latest advice is to follow the steps in the Technical Knowledge Base (TKB).

Resetting the TPM might fix the issue for some computers, but it can also affect Windows security settings and may require extra setup or recovery. That's why we included a warning so you can decide whether to try it.BIOS updates are carefully tested before release. For older products that are no longer supported, we may not be able to release new BIOS updates.

At this time, this is our final recommendation. If anything changes in the future, we'll share an update through our community.
