Intel NUC10i5FNK

Hello,

I’m trying to do a clean BIOS for a NUC that doesnt boot so I try do copy ME Region to new bios.
I’ve dumped original BIOS (v0058) and downloaded last bios.bin (v0065), but the last bios use CSME 14.1.74.2355 and I cannot find it in repository.
My dump use v14.1.65.1969, it’s present in repository.

It’s my first time trying this, so I’m don’t know what to do next. Any help is welcome.

If this is regarding cleaning the ME region according to this guide:

In the Asus zipfile use FN0065.bin from the BIOS Binary File- folder.

Extract ME region with UEFIToolNE and transfer it to your own dump.

If you want to do the cleaning/ reinitializing yourself: The requested version is linked in the first post of this thread

I was thinking doing the opposite.
I think my bios is corrupted, and wanted to extract ME region from dump to a fresh new bios.

That’s meaningless, there’s no machine specific information in ME region which isn’t added under initialization.
In case of fTPM this might bring additional trouble.

For most NUC machine specific data are in GbE and NVRAM entries, not checked for NUC10 though.

Post a link to / attach your firmware dump if I you want me to have a look.

That would be nice! Here is my dump.

When I put it through ME Analyzer, I’ve got this error :

Error: Detected MFS Low Level File 206 which has not been parsed!

Saw that you tried stock Asus firmware already, and it didn’t work. A stock firmware should work (if properly flashed). If not it’s not firmware related.

(link badcaps thread)

I’ve read that recent uefi intel bios cannot be flashed without cleaning it, but maybe it’s onyl for laptop ?
I’ve flashed asus bios with ch341a. The nuc is acting weirdly, sometimes it stays on steady blue light, sometimes it keep rebooting after 4s. MAybe it’s hardware issue.

Don’t reflash a foreign initialized ME region to another PC. Stock firmware has a ME in configured state which get’s initialized on first boot. Those ME regions can be used for every PC with the same hardware configuration.
For the same machine you don’t need to clean the ME region if it isn’t corrupted for a reflash.

Ok, that’s why my dump is “initialised” and stock is “configured” on ME Analyzer.
Thanks for your help, I’ll check hadware now.
