Fujitsu Lifebook E547 vPro

[tofuSCHNITZEL]

Hi,
I have a Fujitsu Lifebook E547 vPro that does not boot anymore after Windows Update tried to install a new Bios version. Screen stays black no post - only the numblock light blinks.
What I've tried:
I have used my CH341A to read the bios chip (25Q128FVSQ) (Dump attached) - I think the dump is "good" because I could find the Serial number in the data and also the Winkeyfinder found a windows key.
for the lack of any other Idea I took the bios from this post (https://www.badcaps.net/forum/troubl...73#post1651873) copied over the windows key from the original dump and the parts where the serial and model number were written and flashed it to the chip and the laptop is now working again - BUT the boot takes longer because the ME is shot (bios shows ME version 0.0.0.0) flashing a new bios with the Fujitsu tool fails(IHISI 15h failed- error code 0x20 - permission denied by user) - using the windows ME flash tool also fails.
so I hope you can help me put together a proper working bios.
I analysed the dumped rom with MEAnalyser and got: Version: 11.8.94.4494 - Flash Image Tool: 11.6.29.3287
the closes ME file from win-raid I could find is 11.8.92.4222_COR_LP_C_NPDM_PRD_RGN.bin
I also tried to extract the Insyde files from the Fujitsu update pack
I tried to open the old dump with Flash Image Tool 11.6.20.1221 but it cannot be opened (corrupt buffer) - uefitool can open it
so now I'm not sure how to proceed....

I have attached: the dump of the original (broken bios): oldrom.zip
and the the download from the Fujitsu website for the old dumps version = 1.27 for E5x7 vPro): Fujitsu_BIOS_1.27.zip

Here the info to the laptop:

Fujitsu Lifebook E547 vPro
Serial: DS1M001050
Systemboard: CP729430-01
The Bios is an Insyde type Bios

Is it possible to build a working (flashable) Bios image from the old dump and the download from Fujitsu? Any help is appreciated!

Backup not good , read chip again.

Backup not good , read chip again.

Sorry, not possible since I already flashed another bios. why is it bad? the DMI seems to be there as well as windows key and Meanalyser also finds infos about ME - but yes something is wrong with it since flashing back does not bring the laptop to the same broken state as before but a different broken state...
Would it be possible to build a working bios from the E557 bios that was linked in the original post? and just add the DMI data and a working ME section?

Okay - so I have bought a mainboard on ebay for a E547 with an i3 and I used my new xgecu T48 to read the bios from there (attached)
But it turns out its not a vpro CPU and the bios chip is not an W25Q128FV but a W25Q64FV. I still copied over the Serial, Mac and Windows key from the "bad dump" and flashed it on but it seems the laptop is not happy that the vpro parts are missing. it boots and generally works but it seems ME is not working and regular bios update also is not working.

is there a way hoaca388 to cobble together a "vpro enabled" bios from the data in the fujitsu bios update pack and the firmware dump from the ebay board?
