My bios is h20 insyde rev 3.7

@ warlok9000:

At first I thought that you weren't merging the two SPI images together before inserting into FITC as that would cause a crash and is a usual mistake people make. Then I saw that it crashes during the building of ICC settings which I've seen before and means that the ME region's DATA section is corrupted and settings cannot be transferred from it. The only way to transfer settings is by downloading the BIOS from Lenovo and hope that it is a) included (not just BIOS region) and b) EXTR (configured) or by finding another dump from that system online. In your case, Lenovo includes the EXTR ME region at their official BIOS so you can work with that. I transferred the Lenovo ME region to your dump, now you can use the guide to clean, update and configure.

To split them again just check the sizes of the original ones (2MB + 4MB). Since you are only interested in the ME, you should reflash only the 1st 2MB (0x200000) chip which contains the FD+ME regions.

You can certainly take the ME region from Lenovo's BIOS and use that at the guide but there is no point as that file is already considered clean+configured. So you can just copy-paste that ME region to a new 1st chip image (2MB) and flash it directly. Because I don't always trust that the OEM has indeed included a clean (apart from configured) ME region, I tend to take the ME from Lenovo, replace it at the SPI dump (in this case the original ME region is corrupted too) and use the guide on that image with the extra setting changes which are mentioned at the guide (disable Anti-Theft and so on). The file "Y510p_ME_from_Lenovo" is exactly that: your original dump with the ME directly from Lenovo. Just use the guide on that image and then split and flash the 1st chip (2MB).

You can dump the ME region so your Flash Descriptor is unlocked. Thus repairing the ME should be fairly easy. Compress and attach here the full SPI chip dump via command fptw -d spi.bin to repair the ME without losing any board specific data.

What me.bin did you flash exactly with FPT to repair the ME?

You did the right thing by taking the ME region from the Acer BIOS and using that with FPT. The best thing to do though is to follow this guide which will clean and configure the ME region as well as disable Intel Anti-Theft Technology which has been EOL since 01/2015 and is known to cause the 30 minute shutdown problem in some cases. I followed the guide and recreated the ME region only (updated to 7.1.80.1214, cleaned and configured it with Acer settings, adjusted region size to be the same as the one from your dump or Acer bios) so it is attached. You need to download the latest ME System Tools v7.x from the ME thread and use Flash Programming Tool with fptw -me -f me_fix.bin followed by fptw -greset command.

Then the problem is not ME related. I noticed that you are able to dump your ME region which means an unlocked Flash Descriptor, something that Acer has kept locked at their BIOS updates. So you must have used either a BIOS option (ME Re-Flash etc) or some acer tool which temporarily Disables the ME and unlocks the FD for servicing. During that mode the ME does not respond and is not operational. Make sure you are not using anything of the aforementioned methods to temporarily disable the ME and try again.

It most probably triggers the Host ME Region Flash Protection Override (HMRFPO) message during system POST which disables the ME and unlocks FD access for servicing of the locked regions (FD, ME & GbE). The ME is not operational while this state is enabled. After reflashing the ME region with the previously provided me_fix, disable that option with that tool from Acer and run fptw -greset which will reset the ME and reboot in an operational state. If that option is truly disabled, at next reboot you should see that you cannot dump the ME region, the MEI interface device is found at Device Manager and MEInfo/MEManuf should be able to work and display relevant info.
