When I put the new battery in, it was a smidge too far toward the bottom. As a result the logic board didn't quite fit back into place and I was unable to put two screws back in. However, the repair seems successful and my phone is working now. Additional guidance on installing the battery would help.
There were many places where I wished there were clearer instructions on putting it back together; this was a big one. It was very difficult to get the camera back in place. I heard a snap when mine went into place.
