Intel CSME System Tools v11 r36 - (2020-10-31) -> FWUpdate (LINUX64): 11.8.80.3762
Which to choose:
Intel CSME Firmware v11.8.80.3746 (CON H DA) -> 11.8.80.3746_CON_H_DA_PRD_RGN.bin
or
Intel CSME Firmware v11.8.81.3781 (CON H DA) -> 11.8.81.3781_CON_H_DA_PRD_RGN.bin
Can I expect problems if the version of Intel CSME Firmware is smaller than the version for FWUpdate?

@ ibsajc:
Choose the latest. No problem with FWUpdate.

Hello!
can anyone help me to downgrade the ME firmware!? motherboard rog maximus xi gen BIOS 1302 I want to downgrade from 12.0.70.1652v3 to version 12.0.49.1534
I cannot do it myself without damaging the motherboard, I will be very grateful for the help

@foetopsy The first post of this thread covers upgrade and downgrade possibilities. Normal downgrade via Intel FWupdate tool dosn't seem to be possible because of different SVN numbers, so you would either have to use a ME region of an earlier bios, or if none of the earlier bioses includes the desired version, you'd have to create a ME region in the same manner that you would clean one (see [Guide] Clean Dumped Intel Engine (CS)ME/(CS)TXE Regions with Data Initialization )

Regarding getting the ME region into the SPI/ bios chip: It's unclear for me 1) if this board does have an Asus flashback option and 2) if Asus flashback does flash the complete bios or just the bios region. If that doesn't work you'd have to try the options to open the flash descriptor lock for the ME region or use a CH341 flasher.

In addition there's mentioned

that some platforms have the current TCB SVN and/or ARB SVN value permanently set/fused/burned in the Chipset so you cannot downgrade their firmware with another which has lower TCB SVN and/or ARB SVN.

there is a flashback, it only flashes the BIOS, the performance is not satisfied

But they install and work (Windows 10), with this IMEI Driver version: 2040.100.0.1029

with your platform, but not with my platform, there are 2 folders, one folder is for win 7 and other with win 8 driver

I have laptop with a preproduction ME firmware. Just wondering whether there is a way to upgrade it to production. Any help is greatly appreciated!

Hey, so I'm stumped on something...

My System:
CPU - i9900K
Mobo - Asus WS Z390 Pro

I have only 1 remaining yellow Flag in my Device Manager;
-PCI Simple Communications Controller.
From what I've read it is the Intel Management Engine Drivers.

I tried installing your Windows 7 IME Installer Driver; I get "Platform is not supported". The Win 7 folder shows in the subcategory.
I also tried installing your standalone driver, through Device Manager browse, it did not find anything. The .inf and .sys files are in there.

I'm not sure what I'm doing wrong here.

Hardware IDs:
PCI\VEN_8086&DEV_A360&SUBSYS_86941043&REV_10
PCI\VEN_8086&DEV_A360&SUBSYS_86941043
PCI\VEN_8086&DEV_A360&CC_078000
PCI\VEN_8086&DEV_A360&CC_0780

The v15 MSI drivers support (CS)ME 10 & 11 under Windows 7, not 12. CSME 12 is additionally supported under Windows 8 & 10 <= 1709. You should look at older driver branches (v14 maybe) at Station-Drivers or similar which probably still supported CSME 12 under Windows 7.
