26 steps
  1. Turning off your Device

    1. Turn your iPhone off completely to avoid damaging it during the repair. Press the standby button for about three seconds until the slider appears.
    2. Wipe it from left to right. Now your iPhone will shut down completely, which can take about ten seconds.
  2. Removing the enclosure screws

    iPhone 6s - Removing the enclosure screws 01
    1. You need a pentalobe screwdriver to open the iPhone 6s.
    2. Remove the two pentalobe screws at the bottom of the enclosure. They are located to the right and left of the Lightning connector. Put the screws in the same container.

    1. Put your iPhone 6s on a soft, clean surface to avoid scratching the back.
    2. To lift the front panel, 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.
    3. The screen is lightly glued to the frame. Use a heat gun to heat the outer edges of the display to about 60°C (140°F).
    4. Place the suction cup over the Home button (if possible) or next to it. While lifting the screen with the suction cup, insert the hard plastic pick between the aluminum frame and the display frame and press down the aluminum frame. Also use the hard plastic pick to raise the screen. This usually takes several attempts.
    5. As soon as you can lift the screen 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.
