HP Elitebook 840 G3 - "Machine is not in committed state"

[sc84647]

Hi
I have an EliteBook 840 G3 that boots with "Machine is not in committed state!", the system info is correct when displayed in the BIOS screen:

Serial Number : 5CG6481F5D
Product Number : L3C65AV
Description : HP EliteBook 840 G3

I've tried using the BiosConfigUtility.exe from HP BCU (SP143621) which says MPM is in Lock state, and if I try changing that using that tool I get:
<SETTING changeStatus="fail" name="Manufacturing Programming Mode" reason="Access Denied" returnCode="6">
<OLDVALUE><![CDATA[Lock]]></OLDVALUE>
<NEWVALUE><![CDATA[Unlock]]></NEWVALUE>
<SETTING>
<ERROR msg="An operation failed" />
<ERROR msg="BCU return value" real="13" translated="13" />

Also tried booting the SMC.BIN from NbDmiFit/wndmifit on USB (Win+up/down while booting method), but I get "SMC command failure."

How do I put the machine into committed state?

Thanks!

Enabling secure boot, and/or cleaning ME Firmware usually works to clear that error.
