[Help] Acer an 517-54 bios image way larger than IC!

[lfb6]

Now that’s the third thread you open on this machine? How to extract the firmware image was explained to you 6 days ago already!

Look the last two pictures which show starting and ending of the firmware image.

When you look the pic of 7-zip you could read the probable version of your own firmware, it’s 1.17

Reinitializing an ME is described in this guide:

Guide-How To: Clean Dumped Intel Engine (CS)ME/(CS)TXE Regions with Data Initialization Last Updated: 2020-07-22 This guide is relevant to those who need to clean the DATA section of an Engine (CSME, ME, CSTXE, TXE) Region, which is part of a dumped SPI/BIOS image, in order to flash the latter on a different machine of the same OEM model. It is not meant as a guide on how to completely transform a dumped Engine region into a stock Intel-provided one. Although the guide can be used for that some…

Transfering a complete region or volume is done by UEFITool/UEFIToolNE, it’s described quite often here, do some reading.

Your bios version isn’t 1.11. For extracting 7-zip is good enough:

The fd files contain a complete image, packed in by some sigs and flashing tools in beginning and end. Search for iflash / _IFLASH_BIOSIMG in HxD.

Which version to use we had some posts before:

@lfb6

I’d recommend cleaning/reinitializing ME and emptying NVRam volume in bios region or replacing ME region and NVRAM EFI volume with thecorresponding ME- region and NVRAM EFI- volume from a stock bios (uninitialized / from vendor!). Your variant is an a little older ‘GH5XGx64_NoPD’, code parts are identical to stock.

I’ve been trying for days and honestly gave up. If anyone can help me by building me a working image I’d be really greatful

I suggest instead of trying ‘for days’ that you might want to present some (preliminary) results and / or ask some more precise questions?
