Subject: Request for BIOS Update with Corrected AMD fTPM Firmware  

 

Body:  Hello HP Support Team,  

 

I am experiencing persistent TPM attestation failures on my HP notebook with the 887A motherboard and AMD Ryzen 5500U SoC. My current TPM manufacturer version is 3.92.0.5, which is known to fail attestation checks.  

 

I have already updated to BIOS F.38 Rev.A, but the TPM firmware did not update beyond 3.92.0.5. According to AMD’s advisory (PA‑420, June 2025), the corrected fTPM firmware should be version 3.96.x or later to resolve attestation issues.  

 

Could you please confirm if a BIOS release containing the updated AMD fTPM firmware is available for my system, or provide guidance on when such an update will be released?  

 

Thank you for your assistance.  

 

Best regards,  

Saksham Singh
