Hello,

I am requesting a BIOS update that includes the corrected AMD fTPM firmware for my laptop, to resolve the AMD TPM attestation issue described in AMD bulletin PA-420.

System details:
- Model: HP Pavilion Gaming Laptop 15-ec1022nm (15-ec1xxx series)
- Product number: 1U6D2EA#BED
- Processor: AMD Ryzen 5 4600H
- OS: Windows 10 Home (64-bit), Build 19045
- Current BIOS: AMI F.35, 12/16/2024 (latest available on the HP support page)
- TPM Manufacturer: AMD
- TPM Manufacturer Version: 3.92.0.5
- TPM Specification Version: 2.0

The problem:
My TPM Manufacturer Version is 3.92.0.5. According to AMD (PA-420) and Activision's official guidance, any AMD fTPM version in the 3.*.0.* range is affected by a TPM attestation bug and requires a firmware update. The corrected version should be 3.92.5.5 (i.e. ≥ 3.x.2.x). Because of this, TPM attestation fails and Call of Duty / Warzone reports "BIOS firmware: Update Required – Failed Attestation Status," which reduces matchmaking quality and available playlists.

What I have already done:
- Installed the latest BIOS available for my model (F.35, 12/2024).
- Confirmed TPM 2.0 is enabled and "ready for use" in tpm.msc.
- Secure Boot: On. BIOS Mode: UEFI.
- Enabled Virtualization-based security (Memory Integrity) – now shows "Running" in msinfo32.

Despite all of this, the TPM firmware version is still 3.92.0.5, because BIOS F.35 does not include the corrected fTPM firmware.

What I need:
AMD states it provided the corrected TPM firmware to motherboard manufacturers back in 2022, but some manufacturers did not redistribute it. The fTPM firmware can only be updated through an HP BIOS update – end users cannot flash it themselves.

Could HP please release a BIOS update for the Pavilion Gaming 15-ec1xxx series that includes the corrected AMD fTPM firmware (version 3.x.2.x or higher / 3.92.5.5), so that TPM attestation passes?
