After installing the New iPhone 5s Lightning Connector Replacement I noticed there was no foam on top of the new plug, leaving bare metal exposed. I cut a small piece of electricians tape to be placed on top of the new plug to keep it from coming in contact with the metal battery connector bracket
What worked extremely easy for me was I used a utility knife to score on the joint below the home button. The blade went in easy then lightly pried the screen up then followed up the rest of the way with the ifixit opening tool. I’m sure the ifixit Jimmy tool would work as well, instead of the utility knife.
