Did you reset ME? You must either issue the reset command, or remove all power for 1+ minutes, that includes CMOS batter and unplug from the wall, then press and hold power on button a few times while this wait too.

What microcode is shown in in AIDA64 CPUID section, top portion on right? I put 306C3 rev 24 and 306D4 rev 2A (But that one, with two is only in first BIOS I sent named i5250uM.bin)

Flash ME section only with FPT, then do the ME reset either via command or complete power removal. Yes, tonight I will get you BIOS with same new ME and both updated microcodes.

Once you are done trying flashing ME, etc. Please make a complete BIOS dump via FPT, or new backup with your programmer and send here, so I can check if ME is getting programmed/flashed in properly.

I will look at new clean ME tonight too, see if maybe certain setting is needed before redoing it.

* Edit - @sugo - is this BIOS you posted in post #4 crash easily while running linux or android X86
From the manufacturer? If not, can you please provide me a link to download from the manufacturer, I want to check something and need to be sure it's an un-edited BIOS from the board manufacturer, thanks

I'm making you new BIOS now, with updated microcodes and latest ME from that series 10.0.55.3000 -2017 (original 10.0.36.1030 - 2015)

I found this also, from Intel, I think maybe it could apply to your board/CPU even though different CPU model slightly, there is some ME discussion in there I thought maybe you'd be interested to read

* Here is update! *

I changed the SKU type in Intel FIT this time, when cleaning ME. I see your BIOS says "Premium BDW" but original BIOS images import as "Base BDW" maybe that has something to do with ME not working properly because those didn't match originally?
I put that BIOS with Premium BDW in Premium BDW folder, and made a second Base in Base folder like original (original ME config, incorrect per your BIOS images)
Test Premium BDW file first, based on your BIOS images ME should be set to Premium BDW SKU not Base BDW like it was in original dump/ME


ME updated to 10.0.55.3000 (Latest for 10.0.xx.xx series
Microcodes updated to latest for 306C3 (rev 24 1/21/2018) and 306D4 (rev 2B 3/22/2018)

During your flash programming, remove power from the motherboard completely, and make sure this state lasts more than one minute.
Remove power plug from wall or 24/8 pin from board, then remove CMOS batter, after that press and hold the power on/off button on case, or short power on pins for 3-5 seconds.

Then put all back once done programming and start board.

The BIOS file in post #4 is backed up by command " fpt -d",not from the manufacturer.And it seems that there is no offical BIOS at all.

I wanted to know whether the updated microcode will get something change for my pc.So I flashed the whole BIOS by command "fpt -f ".(will try the ME region later)
But to my surprise, the "microcode revision" item still show "not loaded" in the BIOS,although I can see the correct microcode in it by UBU tool.Both the base one and premium one got the same results.
And even I tried the "base.bin",the "PCH SKU" item still show " premium sku".
I will have a try to flash it by the programmer to see whether there will be a different result.

Another question is that if I have used the command "fpt -greset ",is it still necesarry to remove all power for 1+ minutes?

Thanks for confirming about the BIOS dump. Too bad they don't provide a download, what are you supposed to do if you want to update or recover? I mean, what is their response in that situation?

Base/Premium was a ME thing, not microcodes. And yes, I assumed no matter what your BIOS would say SKU Premium, that is why I changed ME to premium in the Premium test file sicne to me that is the correct one to use based on what your board/BIOS says.
And I was hoping that, after ME reflash and ME reset, would correct the ME issue.

On the reset you can do either one, remove all power or greset.
