Getting started

If you get stuck or have questions, you can post a comment for each step. We’d be happy to help.

43 steps
  1. Switching off your device

    iPhone 8 - Switching off your device 01
    iPhone 8 - Switching off your device 02
    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

    iPhone 8 - Removing the enclosure screws 01
    • 2 × 3.4mm Pentalobe

    You need a pentalobe screwdriver (PL1) to open the iPhone 7.

    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 - Lifting the display 01
    iPhone 8 - Lifting the display 02
    iPhone 8 - Lifting the display 03
    iPhone 8 - Lifting the display 04
    1. Put your iPhone 8 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 press down the aluminum frame. Because the display’s glued on, you have to slide the pick all around the iPhone between the aluminum frame and the display frame. Don’t stick the pick in too far on the side where the Sleep/Wake button is because that could damage the flexible flat display cables.
    5. Now use the pick to push the display so the tabs come out of the aluminum frame. Then you can fold the display over to the side.
    6. Set the display on the aluminum frame so you don’t stretch the flexible flat cables too much.

    If necessary, heat the outer edges of the display a few times. Don’t forget that the flexible flat cables for the display are on the side with the Sleep/Wake button. The display is also hooked onto the edge of the earpiece.

  4. Disconnecting the battery contact

    • 2 × 2.6 mm Phillips
    • 2 × 1.0 mm Phillips

    Before starting the repair, disconnect the battery contact to prevent short circuits and avoid accidentally turning on your device during the repair.

    1. Use a phillips screwdriver (Ph00) to remove the four phillips screws. Then take off the cover. Put all the parts in the same section of your magnetic pad.
    2. Now carefully lift off the battery contact by inserting a plastic spudger slightly below the connector.
  5. Disconnecting the display connectors
