Yes, as I suspected you have a locked flash descriptor. You must either do the pin-mod (very difficult due to the small chip size as I said before) or get a cheap programmer to reflash the chip.

Have you tried ASRock's Crashless BIOS feature? Maybe (probably not) this can restore the whole SPI image (including the ME region) and not just the BIOS region. Find information on how to use it via the manual etc and try it. Maybe you'll get lucky.

And yes, the ME does look like it's bricked and thus it's normal to be facing so many issues as it's a critical part of the Intel platform.

If by the crashless means running BIOS update through their routine... yes I did it

According to ASRock

Zitat
ASRock Crashless BIOS allows users to update their BIOS without fear of failing. If power loss occurs during the BIOS update process, ASRock Crashless BIOS will automatically inish the BIOS update procedure after regaining power. Please note that BIOS iles need to be placed in the root directory of your USB disk. Only USB2.0 ports support this feature.

Place the latest BIOS rom image from ASRock at the root of a USB flash drive which

a) must be empty apart from the rom image
b) must be FAT32 formatted
c) must be connected at a USB2.0 port only, not USB3.0 one

In theory, when you start the system with such a configuration, it will try to restore the BIOS. Hopefully the whole SPI image and not just the BIOS region.

Also, under Advanced>Me Subsystem, what other sub-menus & options are there exactly apart from ME Version?

So basically I stick the USB into USB2.0 port....any one...disconnect all drives...I assume, fire it on and it shall automatically start procedure?! On my Asus move I have designated port for similar purpose...OK I'll try it when got from work...what can I lose...besides, you mentioned some pins tone shorted...any clues which ones?

Yes, you need to short pin 1 and pin 5 of your Realtek Audio chip while the system starts. If you succeed (as I said, very difficult nowadays) the system will boot with an unlocked descriptor. It will get locked again after a normal reboot.

1. Shut Down the computer
2. At your motherboard, find the Realtek Audio chip
3. Use tweezers or a paper clip to short together pins 1 and 5

4. Power the PC on and wait for POST screen to show up
5. You can now stop shorting the two pins
6. Boot at Windows. You are now running the system with an unlocked descriptor

Note: The image is an example, you may need to search your exact sound chip's pin location although it hasn't really changed at the Realtek ones for years.

#1207 | Intel Management Engine: Downgrade possible? datum

Sun May 31, 2015 2:09 pm

Hello,

i have an Intel DQ965GF-Mainboard and updated the ME from v2.2.20.1041 to v2.2.30.1046 - working flawless.

But now i can't update or restore BIOS, because it stucks while "updating" the ME. I want to flash the same BIOS, modified with Intel Integrator Toolkit.
What i tried:
-Downgrade ME with FWUpdate Tools, i tried all versions: Not possible
-BIOS-Flash with original and modified .BIO-File: Not working, ME-updating failed.
-BIOS-Recovery with USB-Stick or CD: No screen (as expected), but not working - i don't know why, PC stays on, no beep or restart/switchoff.
-Flash Programming Tool: No access, locked chip (FLOCKDWN)

So, any solutions? External SPI-Programmer? Or modified BIOS with integrated ME-Update?

Thank you for reporting that. Did you use the firmware and System Tools package I have put at the first post? Although I didn't expect issues, noone had reported until now whether everything worked out as intended. Good to know that.

Before ME7 it wasn't possible to downgrade to earlier ME firmware versions using FWUpdLcl. Only with FPT + full ME Region (RGN). However I am not entirely certain regarding the ME2 FPT tool because it was part of the first generation of ME.

Exactly what I thought as well.

A BIOS with integrated ME region is probably the best solution, without getting a programmer I mean. The latest Intel BIOS has ME 2.2.20.1041 inside:

Now, Intel .BIO images have two ME parts: One Region (RGN) and the equivalent Update (UPD) image.

If you were to replace the ME inside the modded BIOS, you would have to do so only for the UPD image since the latest RGN image I have at the repository is the same as your's, meaning 2.2.20 and 2.2.30 that you want.

Maybe, during the BIOS update, only the UPD image is used and not the RGN one. So, you can try to replace the UPD image with 2.2.30 and keep the RGN to 2.2.20 and see if it get's stuck again at "Updating ME" step. Hopefully that will be enough.

Can you try dumping your current ME 2.2.30 Region (RGN)? The commands are Fprogw -d BIOS.bin (for the full SPI dump) or Fprogw -d -me ME.bin (for ME Region dump only). If it's successful (which I doubt because you probably have a locked flash descriptor), I will add the dumped 2.2.30 Region (RGN) to the repository because currently I have up to 2.2.20.

Yes, tools and files are from packages. Updating done with FWUpdLcl under DOS.

I get always the same error, when using fprog under DOS, regardless which command is used:

Zitat
Flash devices found SST25VF016B ID: 0xBF2541 Size 2048KB
Flash program locked! HSFSTS[15] (FLOCKDN)
Checking to see if the correct commands are in the OPMENU and PREOP registers.

An error occured while writing to the write status register of the flash device to enable it!

The ITK is creating an .BIO-file and .exe to flash out of Windows. The PC restarts (i guess it creates a ramdisk?) and flashes the file.

Under Windows 7 i get dll-failure with fprogw.exe - perhaps caused by 64bit-OS.

This lock must be another Intel protection.

Try a newer version of FPT. For example try the one from the ME8 package. FPT is basically a generic Intel flasher, I don't think it matters if you use a newer version of it. Try the commands:

fptw64 -i (to verify your chip can be identified)

and then

fptw64 -d BIOS.bin to see if you can dump it's contents

Both these commands are safe either way (just read data, not write).

Ok, i tried it with Windows XP 32bit. Error: Could not find fparts.txt.

But the fparts.txt is in the same directory........this software is crap!

Later i'll try your solution, but i'm very sure, that it won't work. The fptw.exe version 5 can't recognize the ME, later versions probably too.

FPT only works for the ME generation it was targeted at (though you can use newer fparts lists with older FPT):

For ME8 you need to use FPT v8.x

Also better use the DOS version...

None of the higher versions work. Error 201: FPTw.exe cannot be run on the current platform.

Any solution for flashing a modified BIOS-file or modified iflash.exe with overriding/ignoring the version of ME?

Yes, the only example of that FPT use is for FPT8 which does work on ME7 platforms. Anyway, you haven't tried replacing the UPD image inside the .BIO file with the latest 2.2.30, that may work and "skip" that "Updating ME" stuck error.
