15 steps
  1. Switching off the iPhone 11

    1. Turn your iPhone off completely to avoid damaging it during the repair. Press and hold the Standby button and one of the two volume keys for three seconds, until the "Power off" slider appears.
    2. Swipe the slider from left to right. Now your iPhone will shut down completely, which can take about ten seconds.
  2. Removing the pentalobe screws

    • 2 × 6,8 mm Pentalobe

    You need a pentalobe screwdriver (PL1) to open the iPhone 11.

    1. Remove the two pentalobe screws at the bottom edge of the back cover. They’re to the right and left of the Lightning connector. Put the screws in the same field of your magnetic pad.

    After being opened, your iPhone 11 loses its guarantee for dust and water protection (IP 68 rating).

  3. Loosening the screen

    iPhone 11 - Loosening the screen 05
    1. Put your iPhone 11 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 at the bottom of the display. While lifting the screen with the suction cup, insert the hard plastic pick between the frame and the display and press down the frame.
    Do not insert your tool more than 5 mm into the gap, so you don't damage small parts inside the iPhone.

    If you are using an iFlex, switch to a plastic pick as soon as possible to avoid scratching the frame.

    1. Because the display’s glued on, you have to slide the pick all around the iPhone between the 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 display flex cables.
    2. Now use the pick to push up the display so the clips disengage from the frame. Then you can fold the display over to the side. Rest the display on a stable object.

    Do not open the display further than a little more than 90 degrees to avoid damaging the sensitive flex cables.

  4. Disconnecting the display connectors

    • 5 × 1,1 mm Y-Type
    • Touch connector
    • LCD connector
    • Earpiece connector

    The three display connectors for the earpiece, LCD and touch screen are secured with a metal plate.

    1. Remove the Y-Type screws with a Y-Type Y000 screwdriver and lift off the cover plate. Place all parts on a single field of your magnetic mat.

    Apple has introduced the so-called Y-type screws with the iPhone 7. These are wrongly called Tri-Point or Tri-Wing. To loosen the screws, use a suitable Y-Type screwdriver to avoid damaging the screw heads.

    1. Now carefully lift off all three connectors. Use a plastic spudger for this purpose and get it under the plug very lightly and then gently lever it.
    2. If all connectors are off, you can remove the display. There may still be glue residue on the frame and display.

    • 3 × 1,1 mm Y-Type
    • Battery connector

    Now disconnect the battery to make the iPhone completely disconnected from the power source.

    1. Loosen the screws on the cover plate above the battery contact.
    2. Remove the metal plate and put all parts together on a square of your magnetic mat.
    3. Now carefully lever off the battery contact with a plastic spudger and bend it a little to the side.

    • 1 × 3,0 mm Standoff
    • 1 × 1,5 mm Phillips
    • Lightning connector
    • SIM card reader connector

    With the iPhone 11, the SIM card reader is again a single component as it was with the iPhone Xr and can be replaced individually.

    1. First remove the SIM card holder from the device.
    2. Then push the small pin back into the housing.
    3. Next, disconnect the large contact of the Lightning connector assembly. The SIM card reader connector is located below it.
    4. Loosen the two screws of the cover.

    For the Standoff screws there are special screwdrivers with a centering pin in the middle. With this the screws can be loosened easy. Alternatively, you can also use a narrow slotted screwdriver.

    1. Then remove the cover and separate the connector carefully with a spudger.

    • 2 × 1,5 mm Phillips
    1. Next, loosen the screws that hold the SIM card reader in the iPhone.

    A small metal clip is screwed down with one screw. Note the orientation of the clip so that you can reinsert it correctly later.


    1. When all screws are loosened, you can remove the SIM card holder from the device.

    • SIM card reader connector
    • 1 × 3,0 mm Standoff
    • 1 × 1,5 mm Phillips
    • Lightning connector
    1. Then plug in the connector of the SIM card reader. It's a bit more difficult to reach, so you can use a spudger to connect it. Make sure it clicks into place properly.
    2. Then put the cover plate back on and screw it on.
    3. Finally reconnect the wide connector.
    4. Insert the SIM card holder. You shouldn't feel any strong resistance, otherwise the card reader is not yet positioned correctly.
  10. Connecting the battery

    • 3 × 1,5 mm Phillips
    • Battery connector

    Finally you can connect the battery contact.

    1. Position it over its place on the logic board and press it down.
    2. Put the metal bracket on and screw it down.
  11. Attaching a new frame sticker (optional)

    iPhone 11 - Attaching a new frame sticker (optional) 04
    iPhone 11 - Attaching a new frame sticker (optional) 05

    In the pictures you can see iPhone 8. iPhone 11 is very similar and the glue is applied in the same way.

    1. To make sure that the new frame sticker will really stick, remove all glue residue and dirt from the metal frame.
    2. Remove the first protective film layer of the frame sticker.
    3. Position the frame sticker carefully on one edge of the frame and attach it gradually. Make sure the frame sticker is positioned evenly and press it on. You can use the plastic spudger to press the adhesive on.
    4. Remove the next large protective film.
    5. You can leave the small protective films on for now and remove them when you've connected the display and attached the bracket plates. This prevents anything from sticking to the frame sticker before you install it. But you can also remove the films right away.

    Please make sure the frame sticker is positioned correctly. Each corner has a different shape, which you can use for orientation.An iPhone repaired with a frame sticker will be protected against dust and spray water, but it will not be 100% waterproof!

    • Display connector
    • Earpiece connector
    • 5 × 1,1 mm Y-Type
    1. Place the display unit on the edge of the frame and rest it against a stable object, in order not to overstretch the sensitive flex cables. Make sure your device doesn't slide away.
    2. Connect the two display connectors and the connector for the earpiece.
    3. Make sure the connectors attach properly. Don't slip and bend the socket contacts on the logic board.

    Then insert the bracket plate and fasten with the screws of the same length.

    Before you finally close the device, you should test it to make sure that all functions work.

    Especially check the component you replaced. But also check if all other components still work correctly ( for example if the display is correctly connected).

    1. Test the touchscreen. Select an app and drag it all around the display. If the app follows your finger everywhere, the touchscreen is working correctly.
    2. Test the brightness of the display.
    3. You can call somebody to test the microphone, speakers, earpiece and proximity sensor.
