5a. If at this point you realize there ISN'T enough slack to rotate the outlet, don't force anything. You could temporarily detach one or more wires in order to do job, but if you are not confident about doing this, you can just leave it upside down until and if you get some help. It won't really hurt anything, it's just annoying.
6. Gently push the outlet back into place and screw it back down.
7. Put on the cover plate.
