The screwdriver provided are of very poor quality. After the 4th screw, they turn into the void. In the end I invested in a real Torx T4 screwdriver. Besides, better to choose a touch screen with frame (which does not cost much more expensive) because it is very difficult to recover the chassis that is glued strongly to the original screen. This takes time and patience: So I have serious reservations about the comments from people who claim to have repaired their phone within minutes. Apart from this detail, the repair is not so complicated. Thank you You Tube.
