HP Struggling to fix broken firmware for top model omen
I have posted this on HP Support a few times and contacted support, so far no fiix for a 5000$ laptop. Many Omen 16 MAX laptops have a bug in the firmware that stops COD Warzone and some other games to fail. Details needed to fix the problem are below, but HP needs to correct it, you can't do it yourself. The result: Failred attestation error as it appears the bios is not consistent and you could be cheating. I'm not, I just have an HP bios that is not working as it shoud.
This is a firmware spec-compliance issue, not a game/software support request — this needs to be routed to firmware engineering.
Summary
On the OMEN MAX Gaming Laptop 16-ah0xxx, the Insyde BIOS (F.22, 29-04-2026) does not produce a TCG measured-boot event log that matches the actual PCR0 value in the TPM. As a result, Microsoft Azure Attestation (and any application relying on Remote Attestation, e.g. RICOCHET Anti-Cheat) cannot fully attest the platform.
Evidence (Windows 11, Build 26200 — TPM-WMI Event ID 1041, Attestation Readiness Verifier):
- HealthStatus: "Possibly attestable"
- PcrsMatchTcgLog: false
- BitMaskOfPcrMismatches: 1 → PCR0 mismatch
- SoftwarePcrReplayHresult: 0, HardwarePcrReplayHresult: 0 (replay succeeds mechanically; this is a content mismatch, i.e. missing/incorrect PCR0 event logging by firmware)
- EkCertIsAvailable: true, TcgLogFound: true, SecureBootEnabled: true (verifiable from TCG log)
- Bitlocker PCR7 Binding State: Binding Possible
This rules out user configuration: TPM 2.0 (Intel PTT), Secure Boot, UEFI, GPT and PCR7 are all correct. The defect is that the firmware does not measure/log all PCR0 (platform firmware) events into the TCG event log per the TCG PC Client Platform Firmware Profile Specification, so the log replay does not reproduce PCR0.
System details
- Product: OMEN MAX Gaming Laptop 16-ah0xxx
- SKU: B9EY6EA#ABH
- Baseboard: 8D41
- BIOS: Insyde F.22 (29-04-2026), Embedded Controller 38.46
- CPU: Intel Core Ultra 9 275HX
- TPM: Intel PTT (INTC), fw 700.19.1005.2175, PC Client 1.04, Spec 1.59

Please release a BIOS/firmware update for the OMEN MAX 16-ah0xxx (baseboard 8D41) that correctly measures and logs all PCR0 platform-firmware events into the TCG event log per the TCG PC Client Platform Firmware Profile Specification, so that measured-boot replay matches PCR0 and Remote Attestation (MAA) succeeds. Other OEMs have already shipped equivalent fixes for this exact issue.
