So we are trying to update the secure boot database in the firmware to get ready for the UEFI 2023 boot certificate.

 

However, it seems that even if our fleet is up to date with the latest firmware from HP, the 2023 UEFI secure boot certificate is not present in the firmware.

 

When we try to update the firmware with the 2023 certificate, we get the error :

 

The system firmware returned an error Unspecified error when attempting to update a Secure Boot variable.

 

This is from the System eventlog from the source TPM-WMI

 

So far I have tested on these models:

 

HP Elitebook 845 G9

HP Elitebook 845 G10

HP Elitebook x360 1030 G3

HP Elitebook x360 1020 G2

 

All are updated with the latest firmware (from 2025) - but all give the same error

 

Anybody with the same problems?

 

Or maybe a hint how to fix it ?
