@ring00 As written before we don't talk about using a complete bios dump, but using the ME-region. But no one is keeping you from cleaning the ME if you like the idea that serial and MAC for the board are stored there. If you'll follow the guide thoroughly it's not very complicated either.
And I havent seen your board, but there are solutions that almost all chips don't need to be desoldered when using a programmer. Anyway- as far as I can see there is no need for an external programmer since your fd is unlocked. How to flash the ME region was explained to you by @Lost_N_BIOS in the other thread.

@ring00 If you have a working bios it would be easiest to extract as is the ME region from the good bios with UEFItool 0.25, and replace as is the ME region of the bios. That could be done either by fpt if flash descriptor is unlocked, or by inserting as is the ME region in the bios dump of the 'bad' board with UEFItool and flash it back by programmer.

Oh, I see now! You weren't advised by Lost_N_BIOS to flash a complete bios, but to take the ME region, just as I explained again above. Since there are settings stored in ME you can't use any ME, but you can often (almost always for older versions) re-use a properly configured and working ME region of an identical board.

I don't understand how can I use BIOS dump from another MB (though identical) with another MAC address and serial number. I must make a cleanup of BIOS dump from this data. Also I have the same ME region from repo. I prefere not to use programmer since it requires desoldering BIOS chip.

Plutomaniac, thank You very much. Please explain, what is better - using FPT from DOS or FPTW64 from Windows 10? Coderush advised DOS, I use DOS since it is faster and no need to install OS. Strelec USB flash disk gives a ready-to-use DOS.

I cleaned dumped BIOS, replaced ME region by the same version from repo, did all steps and flashed BIOS. Now I have constant reboot. Please help. I attached dump from normal MB (fullback )and with broken ME (errback). I can flash BIOS after desoldering chip, but I need correct image. I did all according to instruction

It doesn't matter if you use FPT for DOS, EFI, WIN etc. Follow this guide on the dump from the other working machine, use UEFITool to "Extract as is.." & "Replace as is..." the ME region from the "cleaned" image to your own and flash the output back via FPT or programmer.

The reboot issue is not related to any advise you received here. It doesn't make sense, ME wise. Do as you were told but also clean the "healthy" dump before transferring the "cleaned" ME region to your own broken dump. Then you can flash it back. The instructions are mentioned at the previous post. If the hardware is ok, the firmware is meant for that model and you are not trying incompatible/untested configurations or any mods, it should work just fine. Anything else (mods, untested combinations etc) are not related to this thread.

So to sum things up, I extracted my Dell 5289 bios via SPI and inserted a clean ME region per the guide, - using the FIT tool in the associated Systems Tools folder. Everything seems to be OK but when I run MEMANUF or MEINFO, I see near the bottom; "FPFs and ME Status: No Match".

What does this mean and where did I go wrong?

See the attached PDF.

Thank You

Good afternoon dear Plutomaniac. Please help me with Bios on my XPS 9570. At the time of the update, the laptop turned off and did not turn on again. I've tried clearing ME many times but still doesn't work. I downloaded some from the forum, but after installing the sound card driver, the sound disappears. Please help me make a normal BIOS so that everything works.
