Since Nov2025… Face, Badcaps and so on…and nothing…no wonder… with such mess, much more clear now on Badcaps forum…for sure it’s not a non-asset user that will lose such time…would you?
Is there any original readings of main bios IC? Yes…then try the CSME clean guide. (EDIT: Done already in Badcaps forum…)
Did you already got it, regarding the IC with nVidia vbios…not EC data that most likely is part of the main bios code like most of the laptop bioses…not all, but this seems the case.
Have you found any original OEM (PC Specialist Optimus Series / XMG Core 17 (E20)) bios files?
Then use them to swap/edit volumes in your dump.
Here’s an Avell KIC C62 GK7MR(OR) based dump and that’s all, good luck with it but it seems a hard case to solve by using forums, due to severity of the case that needs work from a Tech IT shop professional, not inexperienced/curious users, pay for it.
