Getting started with the repair of your iPhone 12

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

16 steps
  1. Switching off your iPhone12

    iPhone 12 - Switching off your iPhone12 01
    iPhone 12 - Switching off your iPhone12 02
    iPhone 12 - Switching off your iPhone12 03

    Before repairing, we recommend that you use our checklist to test the basic functions of your iPhone 12. This way you can check afterwards if your repair was successful.

    Switch off your iPhone 12 after testing to avoid a potential short circuit.

    1. Press and hold the side and volume down key simultaneously for a few seconds.
    2. Wipe the displayed slider "Switch off" from left to right.
    3. Your phone will now shut down completely within a few seconds.
  2. Removing the Pentalobe screws

    • 2 × 6.8 mm Pentalobe

    As soon as you open your device, the warranty for protection against dust and splash water (IP68 classification) expires.

    The iPhone 12 is opened via the display, which is glued and additionally fixed with two pentalobe screws. The screws are located on the left and right of the Lightning connector.

    1. Unscrew the two pentalobe screws with a pentalobe screwdriver.
    2. Then put them into a screw storage.

    We recommend using a screw storage for your repair (e.g. an old sewing box). That way you can store all removed parts and screws safely and keep the overview. On our high-quality magnetic pad nothing slips and you can arrange everything in an organized way.

  3. Heating up the edge of the screen

    Used tools
    Heat gun

    In order to be able to remove the glued screen more easily after loosening the screws, first heat it up with hot air. Therefore, use a hot air device, such as a heat gun or a regular hair dryer.

    1. First place your iPhone on a soft, clean surface to avoid scratches on the case.
    2. Then heat the edge of the screen by running the heat gun evenly over it.
    As a rule of thumb, you should still be able to touch the screen without burning your fingers.
    Used tools
  4. Lifting up the screen

    When the glue of the screen is sufficiently warmed up, you can start to carefully detach it from the rest of the case.

    1. Start by placing a suction cup on the bottom edge of the screen. Pull it slowly upwards to create a narrow gap between screen and case.

    You can use the iSclack as an alternative to the suction cup. In comparison you have to use much less force to create a gap.

    1. Insert a flat stable tool into the gap to enlarge it. We recommend a hard plastic plectrumfor this purpose.

    Used tools

    Once a gap is created, you can detach the screen from the rear case piece by piece.

    1. Move the hard plastic plectrum once completely around the edge of the screen. Press it upwards at the same time to release the hooked lugs of the display from the rear case.

    You can reheat the glue with hot air at regular intervals to make it easier to remove.

    Never open the screen more than 180° while the sensitive screen cables are still connected. Otherwise, they could tear.
    1. When the screen is completely detached, you can carefully unfold it towards the volume buttons. Lean it against a stable object to avoid overstretching the flex cables.

  6. Removing the cover plates

    • 6 × 1.0 mm Y-Type

    To remove the screen completely, you have to detach the battery connector, the two screen connectors and the one from the earpiece which sits on the display unit. These are located under two cover plates.

    1. Unscrew the six Y-type screws from the two cover plates with a Y-type screwdriver and put them in your screw storage.
    2. Then carefully remove the two cover plates from your device with a pair of tweezers.

    The larger of the two cover plates is hooked in additionally.

  7. Detaching the battery connector

    • Connector

    After removal of the cover plates, all four connectors are exposed. To avoid a potential short circuit during the repair, you should always detach the battery connector first.

    When separating connectors, always start from the side where there are no small components on the logicboard. This way you avoid potential damage.

    1. Then use a plastic lever tool to move under the connector and carefully separate it from the board. We use a plastic spudger for this.

    When separating connectors, always start from the side where there are no small components on the logicboard. This way you avoid potential damage.
    1. Use a spudger to go under the three connectors one after the other and carefully pry them off the logicboard.

    Two of the connectors are on top of each other.

    1. Then put the detached screen aside.
