Need help cleaning ME region on Zbook 17 G1 bios dump

[loopster]

Hello guys,

could I please get some help cleaning the ME region of the attached Zbook 17 G1 bios dump (CH341a, neoprogrammer, chip-desoldered, dumped twice, identical checksum)?

Symptoms, delayed BIOS post (ca. 45 secs.) keyboard not working, touchpad not working, booting linux live, console says "Management engine not configured".
I tried following the ME firmware cleaning guide, but whatever Flash Image Tool version I try, I get the same error:

Error 10: Failed to open with processed commands.
Unable to open file: C:\Users\Elitebook 820 G2\Downloads\NeoProgrammer V2.2.0.10\NeoProgrammer V2.2.0.10\Dump\Zbook 17 G1 dirty.bin. Reverting to default configuration.

Can't get the bios to open.

Bios is analyzed alright in ME Analyzer.

What did I do wrong :-( ?

Ok, I see, I am definitely a moron. I didn't realize I need Flash Image Tool version for V9.0.
I'll try to get this done myself

Well, now at least I get a different error after replacing ME Region.bin in folder Decomp, opening the untitled.xml and trying to build the image

I used FIT 9.1 and 9.0.22.1467_5MB_PRD_RGN.bin ME firmware and got no errors. Rename firmware as "ME Region.bin" and DELETE old ME Region.bin Maybe you deleted GbE Region.bin

Thanks man, I just used Intel ME System Tools v9.1 and 9.0.22.1467_5MB_PRD_RGN.bin prior to seeing your post, and it worked for me as well.
But we got different checksums on our outimages. Is that a cause for worry?

The good news: after flashing the cleaned bios (I took yours, you are the pro :-)) the laptop still turns on.
The bad news: the behaviour is exactly the same, nothing has changed. What's next? On to the EC bios? Where do I get a clean copy?
Can I take any version from this forum for 17 G1?

My problem does not seem to be bios or ME region related after all. After flashing a few main Bios and EC bios versions,
I checked the power button and the zif socket for the powerboard flat ribbon cable (with the PB disconnected), and I only have 2.5V on that 3.3V line.
Nevertheless, the laptop always powers on, but with the symptoms described above.

I do have stable 3.3V on the Bios chip,so 3.3V must be healthy in general, but something seems to drag it down on the PB line.
That's going to be fun, hunting for this stupid fault 😒

Nope, that's not the problem either. My other Zbook 17 also has 2.4 on this line.
Can I just dump the Bios from the working one, and also drop it into the other, and it'll work,
or is that not advisable? Could someone repair my original dump, ME region cleaning alone does not fix it.

Nobody got any experience dropping a Bios from a working motherboard into another one?
Are there any secondary checks with the existing hardware involved?

How would I go about this, dump the Bios from the working one, clean the ME region, and flash it onto the non-working board?
