After a few days the display came on and the installation could be done without problems. To facilitate the work, you should have a pair of tweezers handy and also a magnetic screwdriver is practical.
The phone looked like new and visually the display has no lower quality than the original display. Those who try the conversion, it should definitely try himself. Instructions gibts also YouTube. One should only make sure that the cable can break down easily, because they are so thin and even that one detaches the silver dust guard in front of the speaker next to the front camera and it sticks to the new display.
