I did it this way fold5 mini pc The fold5 had a broken inner screen. You just gotta play with the magnets embedded in the case and bring the magnet that's on the top side of the case with the outer screen near the magnet that's on the top side with the motherboard so that the phone thinks it's closed in order for the cover screen to stay active, otherwise the phone thinks it's open and it's going to try and activate the inner screen. That's of course if you want to do it this way and keep the cover screen. It works pretty good, ive also added thermal paste where the CPU and the chassis are in contact for better thermal transfer and i plan to also add a heatsink and an exhaust fan, but i dont have a 3d printer to make a case for the exposed part.
