Hello,

Apparently the TPM is missing the two following keys (called "variables") in the BIOS' secure boot menu:

• Authorized timestamps
• OsRecovery Signatures

I tried restoring factory keys and resetting the BIOS and it still can't find these keys, and Windows still isn't able to detect my TPM in the Device Manager.

Do you know if there is a solution to reset / flash or update the TPM firmware ?

From the BIOS it seems to an AMD firmware v. 3.87

Many thanks, in advance.

You should find it in Security Devices in the Device Manager.

It was not detected in the Device Manager (had an exclamation point over the TPM's icon)

UPDATE :I tried to import EFI keys from the secure boot custom menu and I think I bricked my motherboard : PC would not even load the BIOS. Tried to clear CMOS, flash BIOS and everything but nothing worked. So I bought a new one...

Advice : don't mess with the secure boot keys unless you really know what you are doing

Have you enabled TPM or fTPM?

Enable fTPM..

Also please list system specs..
