With the following video tutorial I have changed the display: [...]
It took me over 3 hours, but since it is a bit exhausting with the small screws.
Part is not specified in the video, but it is also not difficult again to find the right work site.
However, one should note that one of the home button, loudspeaker-dust and a small plastic thingy that comes from his old display on the front camera, from power and sticks to the new display. For me, the old black tape do not have enough stuck, so I did not need the supplied double-sided adhesive tape.
It works again perfectly normal and there is a maximum of a very small difference in the color of the display can be seen. In addition, the old home button sits not perfect, maybe you should because it use the included adhesive sheet.
