There’s nothing dramatically wrong with the dumps you presented. Of course one can’t compare them to the stock bios.
Do you have a bios code? Older Samsungs had a bios code together with bios version to recognize them, like AAY in this example:
In your case:
Take the old bios region, combine it with FD and ME, empty NVRAM and clean ME according to
Clear CMOS before restarting, expect a longer boot process and several reboots.
Seems You have a software tpm in ME firmware, that might be a possible reason? If you want to go stepwise:
- Take a complete image and just clean ME
If that doesnt work - combine the earlier dumped bios region with cleaned ME/FD region
If that still doesnt work - take the firmware of the last try and empty NVRAM (might be that you miss some machine specific data)
Good luck!
