I followed the instructions for changing the battery exactly. The hardest thing to reassemble was the home button connector and metal clip. I was able to pull out the battery adhesive strips with a few breaks but I could grab the fragments with a tweezer and keep pulling them out. On first reassembly I got a bad screen image and no touch response. I recommend you test your phone before you snap the case back together. I found one of the cables had come unsnapped so I had to redo all that more carefully. The second try everything worked great. I am very pleased that my 5s is now back like new again at such a low cost of repair.
