those top screws in red are in very tight, and at an angle that prevents using a long screwdriver. I've found the only way I could get them out is using a bit, held down by my finger at the appropriate angle, while turning it with pliers.

its easy enough to use tweezers to remove the clips.

There is a metal plate glued to the bottom of the cable. It is easier to get a tool under the metal plate and separate it from the midframe than to unglue the cable from the plate. prying against the plate provides some protection for the cable.
