EXCELLENT Instructions! 1:15 first time. Worked great, saved me the cost of a new phone. The "genius bar" said it couldn't be fixed, talk about self serving "you will have to buy a new phone!"
0) Be careful when taking the front off, I snapped off one of two pieces near the lightening connector!
1) Print out the instructions (yes its a lot of pages, but trust me)
2) As you take off screws and pieces tape them to the instructions where they go
3) YOU will thank me later.
If I had not done this I think it would have been twice as long, and likely made mistakes and perhaps damaged something with the wrong length screw. I kept like screws together under one piece of tape, next to each color indicator.
