HP Probook 650 G4 - Lost power?During AMT de-provision process, now I get blackscreen

[rive.hafintosh]

First here is how things went down.

I entered the bios and began to de-provision Intel AMT - it began with a reboot and then prompted me to de-provision AMT - proceed Y/N -
I pressed Y and hit enter, and I thought the PC shutdown, but perhaps it actually lost power at this point. I had the power adapter plugged in but apparently the plug from the wall came out of the brick when I wasn't noticing so 1 of two things could have happened…
Something went wrong with the process, or it lost power during the process and corrupted something
I tried making a HP recovery usb with the bios SW pack and it didn't do any good.
It just powers up for about 30 seconds with a black screen fan spins up, then the power cuts and the laptop goes silent.
Caps lock and numlock keys are flashing I think 5 times which supposedly means bios corruption.
So what's my next step,?
I've already made a dump of the chip with 32mb that contains Intel ME and presumably AMT

I was planning to clean the ME region and try to boot up again after, but I can't find the RGN file for my version of ME.

This link has my zipped up bios dump and my ME analyzer log after calling -dfpt
Only thing of note is
Error: MFS Scratch Page 4294967295 Header CRC-8 0xFF is INVALID, expected 0xC1!

Please assist however you can, Thanks in advanced!

Please include your serial.

Yeah no problem, but as you'll probably see that is it's own problem... The serial seems to return no results in the search for some reason.
SN# 5CG9010W0Q ProdID: 4PY33UT#ABA - I can confirm it is the hex-core model though. Which also seems to have no drivers for the model under it's section, so I assumed the ones in the Probook 650 G4 section were sufficient.

here's your new rebuild bios, it has your DMI attached.

Cleaning me region with the file 12.0.24.1314_COR_H_BA_PRD_EXTR-Y.bin from the repository seemed to do the trick, everything is up and running again.
Except I still can't seem to get rid of AMT's managed status.

Scratch that, factory reset seems to have done the trick.
