If only is were that simple. Those drivers won't install any more (there were installed before) and now running EITHER the Windows FW updater FWUpdLcl64.exe OR the DOS version FWUpdLcl.exe returns an error:

Error 8743: Unknown or Unsupported Platform
Cannot locate hardware platform identification
This program cannot be run on the current platform.

That error is from the same tool that updated the ME firmware in the first place!. Intel Management Engine was greyed out in Device Manager after updating so I removed it but that didn't help either.

I think I might need a new BIOS release to match this ME update.

All back up and running again after re-flashing my BIOS (latest for my board v7.20 over v7.20) from DOS. lex23, I suggest you do the same as you and I had the same issue with PC not powering off on shutdown after this ME patch.

One of the stages of flashing my BIOS was ME firmware installation so that put mine back to 11.6.0.1126 which is vulnerable ("This system is vulnerable" according to INTEL-SA-00086 Detection Tool) but is, more importantly, functional.

I'll wait for ASRock to post something official for my board, Fatal1ty Z170 Gaming K6+ w/i7-6700K.

Looks like Asus is the only one my shopping list, for replacing my old Z170 mainboard, because they prove right now, to handle security issues professionally, like it always should be !!!

I'm waiting a bit longer to cast my vote on this as well. Security is not to be taken lightly. The use of official servers for patches and communication is a cornerstone principle. 

And by the way, I don't see anyone getting "angry" at Asrock on this thread. My posts are out of concern with this issue and with constructive intent.  People chiming in in their own way are justified to do so when Asrock hasn't issued a clear response yet. 

Most people are ok with waiting for a patch as long as they know it's coming. It is easy to interpret Asrock's silence + published patches for 300 series motherboards as ignoring the older models that are affected. So, hence the concern. A simple notice on the website saying that further fixes are underway would suffice. While it appears there is a microsite addressing the issue, I only found it by following this forum thread, and not on Asrock's main support page. Perhaps the communications should be a bit more streamlined? Again, this raises the valid concern that someone out there could create a fake patching site to further exploit the situation. I'm only trying to provide constructive criticism here.

Downloads like this really should use TLS to prevent people between the server and the customers from injecting malicious firmware into people's machines.

Meanwhile, those of you who downloaded the files, what SHA1/SHA256 hash did they have? With sha1sum and sha256sum commands, I get:

Can anyone confirm? Thanks.

After my earlier woes with this patch I raised the issue with ASRock Technical Support. They suggested clearing my CMOS as a remedy but seeing as I'd already sorted myself out by re-flashing my BIOS I decided to try again this evening. This time I used the DOS flasher on a bootable USB drive and all worked perfectly - no CMOS clearing required.

tldr: Windows flasher bad. DOS flasher good.

Bad luck for me, i just tried the USB bootable disk flashing method but with no success.

I got this message : (IME driver version 11.6.0.1026 already installed on my pc)

ERROR 8705 : Firmware update not initiated  due to version mismatch..


Oh well, i will try the windows method another time maybe, i don't feel like flashing my BIOS, reset the CMOS right now.. Ermm

Hi everyone. I still haven't been able to resolve my HDCP 2.2 issue. As expected, nobody's really telling me anything useful. For now, if playback of Ultra HD discs is important, please don't apply ASRock's patch until this gets sorted out.

That said, would somebody with the Z370 Gaming-ITX/ac board be able to do me a big favor? If you haven't updated the ME firmware yet, could you download and run the MEInfo tool (https://www.win-raid.com/t596f39-Intel-Management-Engine-Drivers-Firmware-amp-System-Tools.html) and post the results here? For an apples-to-apples comparison, you'll need to have the 11.7.4.3314 drivers installed from ASRock's support page for the board (https://www.asrock.com/MB/Intel/Fatal1ty%20Z370%20Gaming-ITXac/index.us.asp#Download), you'll also need to have SGX enabled ("Enabled," not "Software Controlled" or whatever) in the UEFI, and it'd help to have the 1.11 UEFI installed. For reference, I've pasted below my results after the patch has been applied.

Thanks.

Can't help you there as I've a Z170 board but if you're up for a minor adventure I'd suggest you try the latest ME drivers from here: https://www.win-raid.com/t596f39-Intel-Management-Engine-Drivers-Firmware-amp-System-Tools.html

The so-called "11.7.4.3314 drivers" you mention are actually v11.7.0.1032. You can see it yourself in mup.xml in the ME(v11.7.4.3314_SW).zip archive:

<driverversion>11.7.0.1032</driverversion>

I have a Z170 board and successfully installed v11.7.0.1045 which is actually called "Intel MEI Driver v11.7.0.1050 MEI-Only Installer" in the link above.

Maybe a driver update will sort you out?

Can't do it. Intel won't let you downgrade ME firmware. ("Error 8805" and then something about the SVN (Security Version Number) preventing it.)
