@malaquita - Here you go, BIOS from #23 used as base, hopefully all is OK I hate X79 ME FW

Change Log -
1. NVME Mod Insert
2. BIOS Menu edit for Bifurcation (@ Advanced >> NB Config (Second/new one) >> IOH
3. Additional 2x ME submenus enabled while doing above (@ Advanced)
4. ME FW update from 8.1.40.1416 >> to >> 8.1.70.1590 (Latest)

@Lost_N_BIOS
It doesn't work, flash is ok, but when rebooting to boot it goes back to 8.1.40.1416.
It is the same as with FWupdater, it makes a small start but quickly restarts and reflashes 8.1.40.1416
I don't know what else to try
Thanks.

@malaquita - I've never seen such thing happen, especially if ME FW is updated via BIOS update, must be something specific to Asrock I'll check around in google.

So, this is known Asrock thing!! They have a backup ME FW inside BIOS region (@ B3160739-1365-48A7-AECB-038652E2B528), if ME FW does not match then it's replaced with the one in BIOS volume
I see these two discussions about this -
Intel Management Engine: Drivers, Firmware & System Tools (76)
https://github.com/corna/me_cleaner/issues/126

Do you have a flash programmer in case I get the edit wrong, @lordkag discussed enough there that I think I can do same in assembly, but I don't see him posted here too often now so not sure if he would stop in here to do it for us.
Never mind, I can see what he did with assembly to do the second method, but I cannot do that (not enough assembly skills). So I would require doing method one for you, which is not tested there, so flash programmer is required if you want to move forward

Or, it's possible, that method #3 can be used (my idea, what we do in Asus), remove the backup ME FW module entirely.

plutomaniac - Have you see ME FW backup module (B3160739-1365-48A7-AECB-038652E2B528) being removed entirely to prevent Asrock ME FW recovery post update?
Or, have you seen lordkag's "Method 1" (replace both with same/same) tested from above link in forums here?

I don't have one, but I can purchase one and wait until it arrives for testing.
Do you(@ Lost_N_BIOS @plutomaniac) have any recommendations?
Many Thanks.
Regards.

@malaquita - that would be best, you need CH341A + U Type Flat IC Extractor, if you need linked examples let me know. YOu can get both for under $4 total shipped on ebay, but that's with slow 3-5 week shipping, or you can usually find faster for more $$ on ebay or amazon etc.

plutomaniac - Thanks, I did link lordkags comments on this above, at least one of the times he discussed and edited it for someone. I checked the files he edited too, and I can't do that in assembly to AMITSE, but I can do the "Method 1" he discussed there (ie replace both), but they ended up not testing and going route #2
Since you don't remember, hopefully we can get method #1 to work, once he has programmer, otherwise I don't think I can help here and he'll have to remain on old ME FW. I know on Asus, even current BIOS, we can just remove the module entirely to prevent this, maybe that can be last resort here too, if method #1 fails.

Hi, i bought this one
https://www.amazon.es/gp/aw/d/B07DJ4GF3N...ob_b_prod_image

It Will arrive on friday.

@malaquita - You also need U type flat IC Extractor, seems this is only one on your amazon, so maybe best to look elsewhere because on ebay it's only $1 USD shipped
https://www.amazon.es/Rtengtunn-Protecci...r/dp/B0828YXFFY

Is this OK?

Thanks.

@malaquita - What is BIOS chip ID, read it off the chip, don't rely on software to tell you. And, what software/version did you dump this with? Asking in case I need to tell you to use certain version to write etc.
DO NOT write the BIOS I sent previously, that is stock BIOS edited. I will have to edit ME FW in your dumped BIOS, or if you know how you can swap ME FW region from the one I sent you into this one, using UEFITool 25, but still maybe wait in case what I said above is true and you need to use certain software or version or write may fail.

Ohh! Sorry, I thought that was your BIOS backup, and hadn't went to grab it until I typed out all of the above At least it's there now ^^

Yes, that is what you need to safely pull out the chip

Hahahaha
Many thanks, It Will arrive on 3-5 working days and i'll do the backup and send you. I'll use the guide of this forum.
Regards.

@malaquita - Yes
Still, once it arrives, or now, tell me your BIOS chip ID, so I can advise software/version if needed

I cant see anything.
P3.0 is original BIOS version, i supone, and behind sticker nothing.
64mb spi(read in motherboard manual)
The programmer and extractor are coming.
Regards.

@malaquita - Clean off chip with alc, to remove all sticker residue, then if you can't get clear image of chip text run something white on chip (cheap thermal paste, chalk, makeup etc), then wipe off gently, this will fill in the lettering with white and make it easier to read/image.
You may not need to rub anything on it, once you clean off sticker residue it will probably be easily readable in new image.

I clean it(a lot) and winband 25064fvat 1412.
