The most fiddly part of the job.
Much easier if you put the screwdriver head on the screw and then insert it into the opening. The slight magnetism will hold it in place. Don’t fully tighten a screw until all the screws are in place. Much like installing lug nuts on a car.
Before you even start: get the iOpener or hairdryer out. You’ll need it
I recommend preheating the case before trying to remove each adhesive tape. Also, try wrapping the tape around a pencil as you pull and stretch the tape. I think that such gives a more even pull across the tape than by using one’s fingers.
