Getting started

25 steps
  1. Switching off your device

    1. Turn your iPhone off completely to avoid damaging it during the repair. Press the Sleep/Wake button for about three seconds until the slider labeled “power off” appears.
    2. Swipe it from left to right. Now your iPhone will shut down completely, which can take about ten seconds.
  2. Removing the enclosure screws

    • 2 × 3,4mm Pentalob

    You need a pentalobe screwdriver (PL1) to open the iPhone 8 Plus.

    1. Remove the two pentalobe screws at the bottom of the enclosure. They’re to the right and left of the Lightning connector. Put the screws in the same section of your magnetic pad.
  3. Lifting the display

    iPhone 8 Plus - Lifting the display 05
    1. Put your iPhone 8 Plus 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 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 then press down the aluminum frame. Because the display is glued on, you have to slide the pick all around the iPhone between the aluminum frame and the display frame. Don’t insert the pick too far on the side of the Sleep/Wake button, because this could damage the display's flex cables.
    5. Now use the pick to lever the display, so the tabs come out of the aluminum frame. Then you can unfold the display to the side.
    6. Lean the display to a stable object to avoid overbending the sensitive flex cables.

    If necessary, heat the outer edges of the display a few times. Don’t forget that the flex cables for the display are on the side of the Sleep/Wake button. After being opened, the iPhone 8 loses its warranty for protection against dust and spray water (IP 67 rating).
