The fact that you know what SVN is means that you've done your homework, most people don't even read the thread or try to do basic research before asking for help. Kudos to you. Now, the VCN & SVN matter for FWUpdate tool only, direct flashing via Flash Programming Tool or external programmers are not restricted by such things. I do agree that the problem is CSME firmware related due to "LSPCON Ports None" but, unless something is not properly connected (I'm not familiar with HDCP, what it needs etc), then only a reflash will solve it. Your board definitely advertises HDCP ("Supports HDCP with HDMI, DisplayPort 1.2 and Intel� Thunderbolt� 3" , "Supports 4K Ultra HD (UHD) playback with HDMI, DisplayPort 1.2 and Intel� Thunderbolt� 3") so clearly something went wrong. Avoiding anything invasive, I would personally try my luck with ASRock. Maybe they can provide some software solution they use to temporarily unlock the Flash Descriptor on the field to allow full SPI reflashing or similar.

Thanks for the info. I am a bit confused. You mention Flash Programming Tool (which I believe I found) and how it doesn't care about SVN and such. If that's the case, wouldn't I be able to load the original version of ME firmware (11.7.4.3314), cross my fingers, and hope that the flash resolves my problem? My apologies if there's something I'm missing. It sounds like I am since you mentioned unlocking the Flash Descriptor and such. I've done some homework, like reading the initial post, but I suspect there's some stuff that I've missed. :(

EDIT: Derp. fptw64 still requires permission or workarounds to flash.

EDIT 2: I did a bit more research. I'm halfway tempted to try to extract the SPI chip. (I'm not confident in my ability to pull off pinmod, although I'll consider if somebody's willing to help me walk through the steps.) A quick search didn't reveal any immediately useful info. Would someone be able to point out how I can find the chip on my board so that I can tell if it's soldered or socketed?

If resetting Playready didn't help then probably ME 11.8.50.3425 revoked the HDCP 2.2 device key. Perhaps ASRock didn't pay for it... You can check that with Intel or ASRock. If not, then it might be yet another ME bug.

I can have a look at your bios and see if there is a hidden switch to unlock the entire ME partition so that you can dump and flash it.

@ crown_nick:

The SPI chip consist of regions such as Flash Descriptor (offsets, sizes, read/write permissions between regions), GbE, Engine & BIOS. All software flashers rely on the read/write permissions set at the Flash Descriptor, that includes Flash Programming Tool. FWUpdate is a special tool which updates the Engine firmware by communicating with the CSE itself so the FD read/write permissions don't matter. It does however abide to Engine firmware upgrade/downgrade checks such as SVN and VCN.

In your case, the FD is locked as per Intel's recommendations so there is no read/write access to the Engine region of the SPI chip. To unlock the FD at your motherboard, one could find a jumper (none), set a BIOS option (none?), use a cheap hardware programmer (too invasive for your liking, SPI chip soldered not socketed) or do the "pinmod". The latter is done by shutting down the system and then shorting DVDD & SDATA_OUT pins at the Audio chip (should be pins 1 & 5 for Realtek, starting from the marked dot) while the system boots (stop once the OS starts to load). Note that the Realtek pins are very small nowadays and may take some tries. You can check if you have read/write access to the CSME/Engine region either by running MEInfo tool and checking "Host Read/Write Access to ME Enabled" or by testing via Flash Programming Tool "fptw -d spi.bin".

Because your SPI chip is soldered, the viable options for you are the BIOS option (hidden usually - what jockyw2001 suggested) and the "pinmod". Both are safe and non hardware invasive. Personally I would first ask @jockyw2001 to look into the BIOS in case there is a hidden option. If that is a no go, I would give the "pinmod" a try.

I went back and tried to follow the PlayReady directions. I don't think they're applicable in my case. The stuff I was told to rename didn't exist (I do have all the proper files & directories exposed), the CleanDRM binary log made it look like nothing particularly interesting happened, and Windows Media Center is discontinued and requires some trickery in order to get it on Win10 in the first place. I'll try again if I'm truly stuck but I suspect this is a dead end. :(

Revoked HDCP key - I don't think so. In one of my posts, I think I mentioned that the Z270 version of my board activated HDCP 2.2 via an upgrade of the MegaChips MDCP2800 chip (DisplayPort 1.2 -> HDMI 2.0 converter). A special key was flashed into the chip alongside upgraded firmware. I suppose there could be something in the ME firmware too but my gut suspicion is that there isn't.

Regarding the BIOS, I won't turn down a peek if you're offering. Thank you!

Thanks for all the help and patience! I'll look into pinmod. I don't see any BIOS options that imply workarounds for the flashing issues but I'll look one last time. Some BIOS options are rather obscure....

Ok I think I found the hidden BIOS option (Me FW Image Re-Flash) at variable 0x70D so let's try this first:

1. Download the attachment and place the "efi" folder at the root of a USB drive
2. Boot from it while the system starts
3. Run "setup_var 0x70D" and you should see 0x00 (zero) as in Disabled
4. Run "setup_var 0x70D 0x01" and that should set the hidden option to Enabled
5. Reboot and run Flash Programming Tool with the command "fptw -d -me me.bin"
6. Do you see a CPU access error or does it complete successfully?

Well, I have good news and bad news. The good news is that this worked! Well, I had to change the FPT command ("fptw -me -f me.bin") but it worked. When I bounced back to the BIOS, it showed the downgraded ME firmware (11.7.4.3314). Amazing work. :) The bad news is that HDCP 2.2 is still broken. I also downgraded the LSPCON firmware to 1.66 (the original version on the board), thankfully with no trickery involved. Same result. I suppose it's possible the LSPCON downgrade somehow screwed up but nothing in the logs seems to indicate as such to me. "LSPCON Ports" is stil "None" under MEInfo, for example.

I've done some more research and think I've narrowed down the results. Intel has a white paper on High Dynamic Range (HDR) support. I read it, and it's probably the most cohesive document regarding what exactly goes where. It looks like, as expected, the CSME firmware is required in order to achieve A/V link protection via HDCP 2.2. The LSPCON chip also must support HDCP 2.2, and does so by having a key loaded onto the chip as needed. I'm guessing that the CSME FW opens a port and talks to the LSPCON chip over the port. The LSPCON chip then talks to the 4K display. (The LSPCON is unnecessary with DisplayPort 1.3 but I don't have that option.) Here are the ideas I have in mind.

- The most likely problem (IMO) is that there was an LSPCON port that was assigned, and it somehow got nuked when I performed the 11.8 FW upgrade. If the LSPCON Port variable needs to be set, and there's a way to write the correct value (fingers crossed that I'll know what it is later today), I'm assuming it'll be possible to reopen the full HDCP link. This should make Cyberlink happy.
- It's possible the 11.8 FW upgrade somehow nuked the LSPCON HDCP key. I don't believe this is likely, especially since Intel tells users to talk to the vendor (chip and/or motherboard), but stranger things have happened. I seriously doubt that my LSPCON FW up/downgrade path (1.66 -> 1.72 -> 1.66) broke anything. I've heard from other people who upgraded their LSPCON FW and had no playback issues.
- For unknown reasons, there's a bug in the latest ME drivers that prevents the system from knowing how to access a proper value. Extremely unlikely. I reinstalled the drivers recommended by ASRock. That didn't help.
- I'm completely wrong about all of this! :)

Any more steps to follow? The only one I can think of is reprogramming the port, but if that turns out to not be the problem, I'm stumped.

Thanks again!

EDIT: Looking at Flash Image Tool, it looks like I have only four options for the LSPCON Ports value: None (obviously not working), PortB, PortC, and PortD. For some reason, I'm not allowed to choose PortA, even if I turn of the 5K display stuff (which is where PortA is currently assigned). Maybe there's some way to flash this value into the firmware? I figure it can't hurt to cycle through the values until things either work or I hit a wall. Alas, FIT won't let me build anything. So, I need to figure that out.

EDIT 2: Damn. Looks like my LSPCON Ports theory was wrong. Somebody running on the Z170 version of my board, and who is able to get HDCP 2.2 to work and play UHD discs (albeit without HDR but that's apparently a motherboard issue), sent me the following MEInfo breakdown. Anything interesting in here? It's not quite apples-to-apples but I'd like to think it's close enough.

No matter what, this has been a very enlightening few days. :) My last real time spent hardware hacking was 15 years ago. I've always missed it. I've just never quite gotten around to trying it again.

Intel CSME 11.11 Consumer PCH-H Firmware v11.11.50.1422

Thanks to SD/Fdrsoft/Pacman for the new firmware!

@ crown_nick:

Very interesting White Paper. I will look into it myself as well, for informational purposes, even if I don't have a system capable of these new technologies. Very interesting edits as well, let's see what ASRock has to say about this. What is the problem with FIT building, there shouldn't be any. What I would try is reflashing the entire older/11.7 SPI image from ASRock via "fptw -f spi.bin" followed by "fptw -greset". If that doesn't solve the issue then it's not BIOS/CSME related (since it worked before) so maybe OS, Cyberlink, LSPCON firmware? But let's wait for ASRock's reply first. Things are looking good though now, especially since you can relfash the CSME firmware and thus the entire SPI chip via software.

Please compress the two text files into a zip/rar archive and attach that. The forum is buggy when it comes to txt attachments (try it yourself).

Intel CSME System Tools v11 r6 (Updated)

@ crown_nick:

There is a new BIOS for your board which updates CSME to 11.8.50.3425 and "Enables Intel SGX" apparently. Maybe there was a bug before? Check it out.

@ Gleb:

As can be seen from the reports, you need to "CHECK_BUP_OVERRIDE_STRAP". You must have set some sort of motherboard jumper or BIOS option which temporarily disables the CSE.

2. Boot from the USB drive while the system starts (UEFI boot mode)
3. At the EFI shell, run "setup_var 0x6A9 0x01" command
4. Reboot manually/forcefully via Ctrl+Alt+Del or similar
5. Run Flash Programming Tool with the command "fptw -me -d me.bin"

You didn't type any command, how is it supposed to work? Equivalently, since you use FPT Windows x64, the command would be "fptw64 -d spi.bin". Follow the steps again from the beginning and type a proper command this time.
