Old man with no electronic skills needed a cell phone.
old phone dead battery. Cheep old man with 7 fingers gave it a try. It works.
Everything went great. I followed the instructions and all went well. The only difficultly was getting ribbon 3 back in place.
I used long thin miniature needle nosed pliers with cellophane tape on the end to grasp ribbon 3 and push it into the connector. It worked well.
