hit an error while working on acer travelmate 5742g management engine firmware update
Intel(R) Core(TM) i5 CPU M 430 - Intel 5 series/3400 - HM55 mobile chipset

ME analyzer from ME System Tools v6 IBX r2 - (2018-02-09) says its an IBX 1.5mb version 6.0.31.1208

MeInfoWin result (Error 9269: Access to SPI Flash device(s) failed)

installed driver version on system is v6.2.50.1050

Intel Management Engine:Drivers, Firmware & System Tools

ME 6 1.5MB v6.2.50.1062 looks like the latest
For systems running ME 1.5MB v6 was the one i was going with
but here is the punch line (Error 8719: Firmware update cannot be initiated because Local Firmware update is disabled)

Unlock Intel Flash Descriptor Read/Write Access Permissions for SPI Servicing

Intel CSME version detection tool

latest bios installed (InsydeH2O v3.5)
bios files includes FLASHIT.EXE,MEInfo.exe,SPI.EXE,SPROM.EXE,Update.BAT in dos folder and PEW71130.exe in windows folder. so maybe there is a way around the blocks (E3. OEM/ODM Servicing Features & E4. OEM/ODM Servicing Utilities)

EzH2O v2.1.0.13
PhoenixTool v2.73

InSpectre

Already checked plutomaniac's Guide-How To:Clean Dumped Intel Engine (CS)ME/(CS)TXE Regions with Data Initialization and his repo.files are good

got stuck at;
D2. ME 4 - 6
step 7
giving me ME Region: Decompose Data: Unknown FPT header version error when building

wanted to try a different version,ME analizer checks out,FIT says hm55 -mobile, v6.2.0.1019 from Intel (CS)ME, CS(TXE), CS(SPS), PMC, PHY & PCHC: Firmware Repositories
FWUpdLcl update_file_name.bin -generic
Error 8713: Firmware update not initiated due to an invalid FW image

Note: Intel (R) Anti-Theft Technology Permanently Disabled? Yes -by default in current, No -by default in update file.i guess it should not matter for updating
seems like all leads to pin method.manufacturer somehow updating this pre-locked files with a setup.but i could not find it

- you deleted your old identical posts and started a new thread- why?

- you can't use UPD files for cleaning/ FITc as mentioned in Section C of the guide:

Zitat von plutomaniac im Beitrag [Guide] Clean Dumped Intel Engine (CS)ME/(CS)TXE Regions with Data Initialization
.......
C. Method Compatibility
.....
Since the purpose of the guide is to clean the DATA section, it is important to choose a clean RGN Engine firmware from the Intel Engine Firmware Repositories thread and not EXTR which is extracted from various SPI/BIOS images/dumps and considered dirty as far as the DATA section is concerned. Moreover, a full RGN Engine Region is required and not an Update (UPD) image. That means that you should look only for Engine firmware of this structure at the Repositories:

cause it does not apply to bios modifications section,not exactly

i am aware.and that is a part of the problem.there is no RNG as an higher version.besides as the guide suggest "all 6-series (ME 7) or older systems must use UPD images in order to initiate a ME firmware update" which is what i am doing here
and you left the part from quote saying "otherwise the closest you can find in case that one doesn't exist or it's not RGN, same SKU etc."
so i did try that aswell.cross checking sku,size,type
side note,EXT files are extracted so considered dirty
i am laying it out with examples.people tend to focus on their own machines first (by searches etc),may set an example in how it played out,i will edit it once i have figured it out.

Maybe you can find and change the value for bios ME protection in NVRAM? There's at least one hidden option in setup:

0x8235A And {15 02}
0x8235C Setting: Ignition ME Protect, Variable: 0x20D[1] {05 09 0D 02 01 F0 01 F1 01}
0x82365 Option: Disabled, Value: 0x0 {09 09 38 00 00 00 00 00 00}
0x8236E Option: Enabled, Value: 0x1 {09 09 39 00 01 00 01 00 00}
0x82377 End of Options {10 02}
0x82379 End If {18 02}

E6. OEM/ODM Hidden BIOS-UEFI Options
bios is UEFI capable but not active (also shown as in hwinfo above).I have tried all the tools EzH2O v2.10.3 not showing information PhoenixTool v2.73 is a mess
ubu tool not recognizing bios files (fd,rom), UEFIT tool's FIT panel is not clickable

fptw -d spi.bin

Error 26: the host cpu does not have read access to the target flash area.To enable read access for this operation you must modify the descriptor settings to give host access to this region

so yes,all leads back to pin method.(E1. HDA_SDO/GPIO33 (a.k.a. "Pinmod")) manufacturer somehow updating this pre-locked files with a setup.but i could not find it (E3 & E4& E5& E6)
which means bios modding,and thats also a challenge since being an insyde bios
