BLACK SCREEN AFTER INSTALL ISSUE:
The first time I put the phone back together, I turned it on but had a black screen. I took it back apart and put it back together again, same thing. I thought that I must had torn something but kept tinkering with it. I discovered that some of the foam adhesive strip that goes on top of one of the wiring harnesses that snaps the screen back to the phone had come off and was actually on the receiving side of the wiring connector bracket (probably not using proper terms here). I used the plastic tool that came with the kit and removed it (I was careful not to touch with my fingers for fear or oil getting on the harness). Tried again still nothing.. thankfully I did not give up as it turns out that connector on the far right of the screen connection harness is tricky. I thought I had heard it click before, but I really looked at this time and realized I had to turn it slightly inward to get it perfectly straight, and then it clicked. Success! Hope this helps someone.
