I am thinking, what if I get an LA-9772P mobo, different screen and manage to get an RTX 4050 MXM, would that work? Ofc, I will disable integrated graphics, I am just not sure if it would work, because some people say it will only run in optimus mode and some say that it will work straight away, but you won't see anything until Windows finishes booting up.
I've tried that, it didn't work, managed to get my hands on one of those screwdrivers, everything is flawless now, i7 4980HQ mutant is now installed, one missing pin didn't really do anything bad, from what I see.
Try this, I hope it works out for you, I can try to send some Techpowerup ones but I am not sure if it will work properly

Can you provide the ROM/flash files? I can do it right now, I made a quick access for my BIOS + ME chips in the laptop's frame so I can do it fast with my CH341A v1.7
At this point I am sure you know how to use ATIFlash and you have backups.
From what I can tell - this VBIOS is unlocked for overclocking, I have updated GOP just in case, I hope it works out nicely
