The battery was dead and I bought a new phone. I had to have it working to transfer the pictures to my new phone.
I was warned that those screws are REALLY small and they ARE!!!! It took me about 15 minutes but I got it done.
When taking the screws out of the cover and putting them back in....lay it flat and the screwdriver is just the right height so that you don't have to hold the phone up. Just work on it flat.
