That seems to have done the trick, thank you. Would you mind outlining the steps taken, so that I may learn from this experience? What I did wrong, what things I omitted? In any case thanks very much for that assistance....

Have a system with a broken SSD connector. Got a replacement motherboard from China. Upon install it was slow to start and had 5 slow flashes of caps lock. Resetting to defaults resulted in not being able to get back to BIOS screens, requiring a reflash of the chip (image provided by board supplier). Same result.

I installed EC and BIOS from a donor board, then updated BIOS via network. System was working (did not brick after loading defaults) but still had slow start. Identified ME as likely culprit in slow boot and 5 flash symptom.

Original problem was slow start and 5 slow flashes of caps lock. Resetting to defaults resulted in not being able to get back to BIOS screens, requiring a reflash of the chip.

I loaded bios file into Intel FIT (version 14.06) and changed Intel ME Binary File parameter to point to the ME RGN file and built a new image. I then burned that outimage.bin file back. 5...

Re: HP Elitebook 850 G2 MPM Unlock Help

The procedure worked as expected - again, thanks for the files.

What was interesting is that on the first boot, the system was MPM unlocked. After that it rebooted itself several times doing one restore or recovery activity or another (expected). In the end though, it was MPM locked, BUT the 'Product information not valid' error displays, the various fields are empty, and UUID is all FF so FSMC->SMC method gets MPM unlocked and I can edit everything in wndmifit. Cool

With this as something I can fall back...

Re: HP Elitebook 850 G2 MPM Unlock Help

Thanks very much for the reply. I will work through this and report back with the results.

Just to make sure I understand correctly what you wish me to do, I'll list it in steps:

1) Reflash original dumps of EC and BIOS (it should hopefully come up again with the original bad info)
2) Run MPM 'get' from your provided archive to get the original DMI info (which will include serial #, SKU, as well as other BIOS settings)
3) Edit the config.txt to change the serial number (my original goal), etc....

First of all, I hope this is the correct spot for this post. Please let me know if not.

System:
EliteBook 850 G2
SKU: L4A27UT#ABA
System Board ID: 2216

This system somehow had bad information set - It was set to model 840 instead of 850, although the serial number was OK. So I want to update this and have it all correct. To do this i need MPM unlocked so I can run wndmifit and correct the data. I tried with HP, but the unit is out of warranty so they declined to provide an SMC.bin file. Unable to take the easy way it looks like I'll have to go...
