@KAL - In installed programs, what version ME drivers does it show is installed? If it's V12.xx, then try uninstall drivers, reboot, and then reinstall drivers.
If that does not help, and or then it's not possible to reinstall drivers, let me know and I will remake BIOS for you using other systems known working ME FW as base instead of one of yours (maybe yours is messed up causing all this no matter how I rebuild it)

Hey, i uninstalled it , rebooted and opened dev manager and now intel ME engine is not appearing even in hidden devices. Status of ME in bios is enabled.

Yes, when you uninstall it, then it's gone until you install drivers Now, install correct ME drivers for your system from the manufacturer driver download page

not allowing giving platform not supported am using intel_mei_2019.14.0.1592

Where did you download that? I checked their page, and don't even see ME driver download?!?

* Edit - Install these >> Intel MEI Drivers & Software v2020.14.0.1600 DCH (Windows 10 >= 1709)
From this page near top - Intel Management Engine: Drivers, Firmware & System Tools

same issue giving unsupported platform...
attached hwinfo64 snip for ME showing blue ! in the report donno if this will help figure out the issue

What windows are you using? No, that image does not help anything, ME drivers not installed so ME will not show up in HWINFO
Does ME Show as N/A or 0.0.0.0 in BIOS now?

* Edit - @KAL - Here, program this in, drain all power off motherboard for 1+ minute, then start system again.
This has known working ME FW from user @Kebicle BIOS - http://s000.tinyupload.com/index.php?fil...346681461942344
If this = same, I have one other ME FW from known working users BIOS @haskhafak << This one has newer ME FW than above, we test next if above fails.

If none working, we'll have to ask plutomaniac to look at your MEINFOwin -verbose log, and MEINFOWin -fwsts log

Windows v2004
ME FIRMWARE Version 0.0.0.0
ME FIRMWARE mode ME Failed
ME FIRMWARE SKU unidentified
ME FIRMWARE status 1 N/A
ME FIRMWARE status 2 N/A

Ok will program kal3 now and let you know

Thxs

Yes, ME FW corrupted, looks like you did something to ME FW after programming in test2 BIOS?

* Edit - when programming, be sure you erase then blank check, then open file and write/verify. Then when doing ME FW related stuff, always drain all power from the board and be sure you wait one full minute or more before connecting any power back.

Hey, this is the status now

ME FIRMWARE Version 0.0.0.0
ME FIRMWARE mode ME Temporary disabled
ME FIRMWARE SKU unidentified
ME FIRMWARE status 1 0x80032144
ME FIRMWARE status 2 0x368A0116
ME State Enabled
Comms hub support Disabled
JHI support DIsabled
Core Bios Done Message Enabled

Btw when we erase and rewrite the chip does it erase all ? cause still getting wrong info liike name aspier and serial number wrong etc... is there a way to permanently rewrite all these info ?

Appreciated
THXS

Yes, it erases entire chip. Probably wrong info in BIOS from BIOS source I used/you sent etc, since you flashed in some other users BIOS region initially, correct? Anyway, none of that is relevant right now, we'll fix later.
ME Temp Disabled?!?! Wait, I see, that is unsuppressed item in stock BIOS even and it shouldn't be >> ME State >> Enabled. What do you see at DOS with MEINFO?

Can not start or run due to incompatibility ...
Dos not supported wiyh my laptop, Noticed having 3 hidden devices in deviced manager 2 of them are unknown and the third is PCI data acquisition and signal controller. Also have pci simple comminucation controller showing no driver installed.
Shall i try Meinfo win32? or 64?

No, you can't run MEINFOWin without ME drivers installed, that is why I said to run from DOS. Ignore device manager, without drivers installed, and or INF package, you may see stuff like you mentioned,.
Test1 BIOS has someone else known working ME FW in it (This is where the ES ME FW came from, I now see! This is haskhafak dump from programmer)
Test3 has another users known working ME FW in it (This has Kebicle's ME FW)

BOTH should be working on your system, for sure test3, unless you have given me wrong model information, or if programming in is not going in 100% correct.
Please program in test 3, then without powering up system, dump the chip again and compare contents of dump in hex vs what you wrote, does it match 100%?

Ok will do it now so will erase, blank chech write verify then read directly ? and for sure model info is correct it's on the tag at the back of laptop PH315-51-78NP

Yes, after write verify, close program. Then open again and read/verify, save and then compare with what you wrote, it should be 100% match.
