Hello Pluto, I followed some tutorial over here on site to unlock bios settings for my Acer ph315-51-78np . i dumped my bios with ( fptw64 -d ) bios file v1.26 (DH53F_1A) and with H2OEZE i replaced setup utility only one module i then re-flashed it with asprogrammer and all went well and i have access to all settings now but there is something wrong with Intel Me.for a reason system can not communicate with Me and intel csme detection tool is giving system may be vulnrable. i attached below both MEinfowin -Verbose result as well as MEManuf -verbose. Please can u take a look at it ? i Appreciate in advance. thxs[quote]Windows OS Version : 10.0

Something went wrong with the BIOS modification and it seems that it does not communicate with the Engine firmware properly. It’s not an Engine firmware issue. I have thus moved it to the BIOS section where someone else may be able to help you. On the Engine side of things, if you re-flash the entire SPI image instead of the BIOS region only, you can try following [Guide] Clean Dumped Intel Engine (CS)ME/(CS)TXE Regions with Data Initialization but this looks like a bad BIOS mod.
i tried it 2 times for a certain reason ME firmware is not updating only PMC is giving green as latest and initialised but ME firmware will remain dated to 2018 and red as not latest.
I also tried to use ME_cleaner and followed what is detailed here but it gave me_cleaner result Full image detected The ME/TXE region is valid but the firmware is corrupted or missing. Btw
Ok, try the attached SPI image. Flash it (programmer or fpt -f spi_fix.bin), remove all power for 1 minute and boot. Check if the problem is gone and verify CSME status via MEInfo.
Error 238: The host CPU does not have write access to the target flash area. To enable write access for this operation you must modify the descriptor settings to give host access to this region.
FPT Operation Failed.
though protection descriptors are disabled in bios and bios reflash enabled and spd write access is set to true, am i missing something ?
The Flash Descriptor is locked. You have Read but not Write access to the CSME firmware region. You can use the programmer of course and it will work that way. Thing is, if the FD is locked then I assume that you flashed the BIOS region only before? Maybe via "fpt -bios -f bios.bin" or similar? In such case, the CSME has not been touched so I doubt cleaning it will make any difference because the problem should be at the BIOS side. If you want to rule out CSME firmware, flash the provided "clean" SPI image via the programmer. If the problem persists though, it is the modded BIOS that has problems.
You are z Expert Thxs man a lot i guess it’s ok now since status in bios is enabled normal mode and version is latest. attached MEinfo result and thxs again PlutoM
