    Unlock HP z840 Manufacturing Mode

    Hi,

    I need to unlock the HP z840 Manufacturing Mode to restore the TPM functionality of the motherboard.

    Is that possible?

    I have posted a thread on HP Support forum without success.

    Thank you.

      Hi,

      this tool is the HP BIOS Configuration Utility (BCU)

      latest version can be downloaded here:

      http://ftp.ext.hp.com//pub/caps-soft...it/HP_BCU.html

      It gives me error when trying to unlock the MPM:

      <SETTING changeStatus="fail" name="Manufacturing Programming Mode" reason="SetBIOSSetting: Access Denied" returnCode="6">
      <OLDVALUE><![CDATA[Lock]]></OLDVALUE>
      <NEWVALUE><![CDATA[Unlock]]></NEWVALUE>
      </SETTING>
      <ERROR msg="Failed to set BIOS config" />
      <Warning msg="BCU return value" real="16" translated="16" />
      </BIOSCONFIG>Process Completed Successfully.....

      It will not unlock the MPM.


      Thank you for your feedback.

        Hi,

        I read this document:

        Instructions on CREATING the MPM-Unlocking SMC.BIN USB Drive

        https://manualzz.com/doc/44691860/in...ng-smc.bin-usb

        I tried using HP NBDmiFit tool

        https://www.finalfixer.com/2020/02/h...mifit-all.html

        But the included FSMC.bin that you rename as SMC.bin is not working on the z840.

        At least I followed the procedure described in the above pdf without success.


        Thanks.

          hi,

          I tried the UefiMpmUnlock.efi but i got "HP MPM protocol is not present."

          so what else I can do?

          Thank you.
