11. For those 4 screws that are a pain in the #$%$ … beep… beep..., I used a Philips screwdriver bit, and a crescent adjustable wrench. You can use a smaller one, or anything else as a matter of fact as long as it fits between those PCB boards and you are able to turn that Philips drive bit and loosen those 4 screws.

NOTE! You must be very very careful, and patient, not to hit anything with that wrench. Those screws are not very tight, in no time they should come out. Be careful around that screw that is close to the ribbon cable “B”, DO NOT damage that with the Philips screw driver bit.
