#1 | me region hm370 .Active boot guard datum

Hello. I strongly ask not to scold me here new.
I have a laptop, after updating the bios through the official program dell G5 15 5587, the problem began. The problem lies in the me region. Clearing the region would not be problematic if it were not for the Platform Protection in my case, the boot guard profile 5-fvme.
I ask to help, with a dump with a clean Me. Dump from spi attached, you need to clean me the region. Thanks in advance!
sorry for my english, i write with the help of a translator.

BootGuard doesn't cover ME region in this binary, so you can clean it up as usual. All hashes (boot BootGuard ones for PEI and AMI ones for DXE) are intact, so it should boot after ME cleanup just fine.

Upload your output SPI image after cleaning the Engine firmware to verify that the guide was followed properly. Also, upload a SPI dump after you have re-flashed the "cleaned" SPI image to verify the CSME firmware health.

Based on the provided files, you have not followed the Engine CleanUp Guide. The "clean" images still have the same corrupted & "Initialized" CSME File Systems, as can be seen from ME Analyzer.

While following the guide myself, one thing I noticed is that the corruption caused issues loading the dumped SPI in the most recent FIT we have as of now (12.0.37.1429).

However, switching to the one the image "me bad.bin" was originally build with (12.0.0.1069), did the trick thankfully so I was able to see the configuration settings properly and thus continue with the guide.
