Broken Intel ME, apparently after a BIOS update

Thank you very much, I’ll try it.
I have a few more questions, but first I’ll describe the results of today’s investigation.

I found some full (!) BIOS firmwares exactly for my laptop model (NP300E7A-S04RU).

All of them are of latest update version 09QA. 2nd and 3rd links require payment for access, but 1st one needs only registration and one post, so I reuploaded it: Samsung NP300E7A-S04RU - Scala3-17 Rev 1.0 -09QA bios.zip — Яндекс.Диск

Now I have some questions:

Can I use the full BIOS I found without any modifications? I suspect that in this case DMI and OEM things like serial number etc will be overwritten, which I would very much like to avoid.
Which BIOS dump I should use for ME restoration: from Universal BIOS Backup ToolKit 2.0.exe or from fptw64.exe -BIOS -D bios_region.bin? As I had already noted above, they’re slightly different, and I have no clue or any idea about the exact differences.
In this topic @plutomaniac not only repaired ME, but also removed Intel AntiTheft, stating that it’s no longer supported and may cause problems. Is it possible to find out in more detail whether it is worth doing this, and if so, how?
