15 - 30 minutes
Power and Lock button would not work. Doesn't depress.
Very difficult to take all of these small components apart and keep up with the tiny screws. The step by step guide was very helpful though and took me thru the process. After all this though, the new button did not help at all. The problem must be with the plastic piece along the top of the phone (on the inside) that this button actually presses against. I did get the phone all back together and it actually works (i had my doubts) but I still have the same issue.
The $25 toolkit was not very good. The plastic piece for lifting up the cables and wires was very helpful but you can get those for 99 cents by themselves. The kit did not contain a bit for the pentalobe screws as it said it did. The other screwdriver tips aren't very good either.
