    1. To protect your iPhone 11 from damage during repairs, turn it off completely. To do this, press and hold the Standby button and one of the two volume buttons for about three seconds.
    2. If the slider shows the message "Turn off", you can wipe it from left to right. Your phone will now shut down completely. This process takes about ten seconds.
  2. Removing the pentalobe screws

    • 2 × 6,8 mm Pentalobe

    Use a Pentalobe screwdriver (PL1) to open your iPhone 11.

    1. On the lower side of the housing, to the right and left of the Lightning connector, you will see two Pentalobe screws. Remove both and place them in a shared field on the magnetic pad.

    Once the device has been opened, the guaranteed protection against dust and splashing water according to the IP68 classification will expire.

    1. Place your iPhone 11 on a soft, clean surface. This will avoid scratches on the back of your device in this step.
    2. To lift the screen, you'll need a suction cup, a hard plastic plectrum and a hot air dryer. Is your glass very badly splintered? Then stick a strip of parcel tape on the glass in advance to protect yourself from splinters.
    3. To remove the glued screen from the frame, heat the edge of the display with your hairdryer to about 60° C (140° F) degrees.
    4. Now place the suction cup on the lower edge of the iPhone. Use the key ring on the suction cup to lift the display. At the same time, push the hard plastic plectrum between the case and display frame and press the case frame down. To remove the display adhesive, you must move the plectrum completely around the iPhone.

    The tool should not be inserted further than about 5mm into the device to avoid damaging any components inside the iPhone. This is especially important on the side of the standby button, as this is where the sensitive flex cables from the display are located.

    You can also use an iFlex instead of the hard plastic plectrum. However, this can leave scratches on the frame.

    1. Once you have passed around the device with the plectrum, you can now push the display upwards using the plectrum This will release the metal clamps from the frame.
    2. Now open the display to the side. To avoid overstretching the flexible cables, you can lean the display against a stable object or use the iHold.

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

    Used tools
    • 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. With a Y-type Y000 screwdriver you can remove the Y-type screws of the metal cover. Place all parts in a common field on the magnetic mat.

    With the iPhone 7 Apple introduced the Y-type screws. Maybe you also heard the term Tri-Point or Tri-Wing, which is a wrong name for this type of screws. To remove them, be sure to use a suitable screwdriver to avoid damaging the screw heads.

    1. Once the metal cover is removed, you can carefully take off all three connectors. To do this, use a plastic spudger, not a metal one. Put the spudger under the connector and lift it gently.
    2. Now you can remove the display. Don't be surprised if there are traces of glue on the frame and display.

    In the pictures we show you how to apply the adhesive frame using iPhone 8 as an example. iPhone 11 is very similar in its design, so the adhesive is applied in the same way.

    1. Remove the adhesive residue from the metal frame and display. This will ensure a proper fit of the adhesive frame.
    2. Now you're ready to apply the new glue frame. Remove the first protective film.
    3. First place the adhesive frame on one edge of the case. From there, you can apply it to the device bit by bit. Do not press the adhesive frame firmly until you are sure that it is in place. You can use the plastic spudger for this.
    4. Now remove the next large protective foil.
    5. Do not remove the last small protective film until you have connected the display and attached the cover plates. This way you avoid that something gets stuck on the adhesive frame.

    Pay attention to the correct positioning of the adhesive frame. The corners are different and help to find the right position.The iPhone is no longer 100% waterproof after repair!

    2. Afterwards, you can plug the two display connectors and the earcup connector back together.
    3. The connectors have to fit correctly in the device. You should not slide them over the slots on the Logicboard, otherwise you could damage the contacts.

    Check all the functions of your phone before you close it again, especially looking at the part you have replaced. Remember to also verify all other components: Are they still working as they did before the repair, for example, did you connect the display correctly?

    1. You can test the touchscreen of your display by selecting an app and moving it across the entire screen. If this works without any problems and the app follows everywhere, the touchscreen is fine.
