   2 x 3.3 mm pentalobe screw

1. Put your iPhone 6s Plus on a soft, clean surface to avoid scratching the back.
2. To lift the display, you need a suction cup, a hard plastic pick and a heat gun. If the screen is severely cracked, cover all of it with packing tape before you continue.Risk of injury due to broken glass.
   
3. The screen is lightly glued to the frame. Use a heat gun to heat the edges of the display to about 60°C (140°F).
4. Place the suction cup over the Home button if possible (otherwise, put it next to the button). While lifting the display with the suction cup, use the hard plastic pick to press down the aluminum frame. At the same time, insert the hard plastic pick between the aluminum frame and the display. This usually takes several attempts.
5. Once a little gap has opened up between these two parts, you can open it further by slightly turning the pick.
6. As soon as you can lift the display a few millimeters, you have to carefully work your way around the outside until it’s loosened on both sides.
   If necessary, heat the outer edges of the display a few times.
