Perfectly and much easier then what I thought.
The guide is very well done and the step by step process is very easy to follow.
I guess even my child could do that with this ;-)
From the beginning, since I found IFixiIT, well documented web site, easy to find what I needed, instructions to verify the exact part I needed, the guide (what a guide!) and the delivery. Everything perfect !
