Which part of my earlier post didn’t you understand?
Look into the first post of this thread, there’s a link to repository with the latest ME versions, including 5 ME 12.0.95…
But that won’t help you, these are most probably HPs anti tampering measures. There’s (probably) another chip on the board which has copies of the firmware for automatic recovery. In addition they might have stored some checksums and hashes in the TPM. You might check for measured boot and verified boot with MEInfo.
If this is a fTPM you can reset this information by re-initializing the ME, but those machines usually have a dTPM.
So you’d have to know how these systems get initialized, where the reduntant parts are stored, how to modify them and how to sell this information to the TPM…
