Great guide! The steps were clear and detailed enough for me to replace upper component ribbon without messing anything else up (which, unfortunately, sometimes does happen) :) The only small thing that I would perhaps mention is that the rubber camera bumper also comes attached to the replacement ribbon, so you don’t have to worry about the old one when you’re removing it. Same with the small strip of adhesive that is holding the contact clip - I recommend removing it since the replacement ribbon also has the same adhesive strip already attached to it.
