iPhone would shut down randomly with high battery percentage remaining.
Pretty easy. I was worried about breaking something, but after watching the video and seeing the chick tug a little and pry the wires easily it went better.
It's all numbered and pretty common sense stuff when you see it. The ribbon marked #3 was the most difficult as everyone says. I broke down and grabbed a pair of needle nose pliers to stick it back in after fighting with it for 10 minutes. As soon as I got the pliers it went in effortlessly. Also getting the battery out is nowhere near as easy as they make it look. I about broke the (spunker? can't remember what they called it) mini crowbar they give you trying to pry the battery up. I ended up getting part of it loose and then using the pliers to grab the tab and rip it up.
