    BIOS Recovery by the  Security  Jumper


      I wanted to downgrade the bios version from 46 to 36 had no success but reading the manual I found the note:


      BIOS recovery using the BIOS security jumper will clear Trusted Platform Module (TPM) keys, Intel®PlatformTrust Technology (Intel®PTT) keys, and High-bandwidth Digital Content Protection (HDCP) keys. These keys will not be restored after the BIOS recovery.


      So now I erased those keys. Am I in trouble? How do I get those keys back? Will I be able to play hdcp 2.2 content now? How to fix that? How important are those keys?


      Thanks for advice.
