Getting started with the repair of your iPhone 11 Pro

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

19 steps
  1. Switching off your iPhone 11 Pro

    iPhone 11 Pro - Switching off your iPhone 11 Pro 01
    iPhone 11 Pro - Switching off your iPhone 11 Pro 02

    Before you start with the repair, we recommend that you test the basic functions of your iPhone 11 Pro using our checklist. This way you can verify after the repair if you have done everything right.

    Turn off your iPhone after testing to avoid a potential short circuit during the repair.

    1. Press and hold the sleep/wake and the volume button simultaneously for a few seconds to turn it off.
    2. Wipe the displayed slider "Switch off" from left to right.
    3. Within a few seconds your smartphone will shut down completely.


  2. Removing the Pentalobe screws

    • 2 × 6.7 mm Pentalobe

    The iPhone 11 Pro is opened via the display, which is hooked, glued and additionally attached to the rest of the case with two Pentalobe screws. The screws are attached to the left and right of the Lightning connector.

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

    We recommend that you use a screw storage to avoid losing any of the removed parts or screws. You can convert an old sewing box, for example. We at iDoc use our high quality magnetic pad on which you can arrange the parts as they were installed in the phone. This way you can avoid losing screws or mixing them up, which can lead to damage of the device.


  3. Heating up the screen

    Used tools

    In order to be able to remove the glued display 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 display 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 display

    When the glue of the display is sufficiently warmed up, you can start to loosen it carefully.

    Opening the iPhone 11 Pro will void the manufacturer's warranty, as well as the warranty for protection against dust and water of the IP68 classification.

    1. Start by placing a suction cup on the bottom edge of the display. Pull it slowly upwards to create a narrow gap between the display and the case.
    2. Then insert a flat stable tool into the gap to enlarge it. We recommend a hard plastic plectrum and the iFlex for this purpose.

    The hard plastic plectrum is only thinner at the corners. On the one hand this facilitates insertion, on the other hand this prevents you from inserting the plectrum too far into the device. The iFlex is made of extra thin, stable metal and has sharp edges. To avoid scratches on the frame of your device, we recommend that you start this step with the iFlex and continue with the hard plastic plectrum as early as possible.

  5. Detaching the display

    Used tools

    Once a gap is created, you can detach the display from the rest of the housing unit piece by piece.

    1. Move the hard plastic plectrum once completely around the display frame. 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.

    As long as it is still connected, never open the display more than 180°, so that the sensitive flex cables do not tear.
    1. When the display is completely detached, you can carefully open it towards the standby button. Lean it against a stable object to avoid overstretching the flex cables.

  6. Detaching the battery connectors

    • 2 × 1.5 mm Y-Type
    • Connector
    • 4 × 1.46 mm Y-Type
    • Connector

    As one of the first steps the battery should always be disconnected to avoid short circuits during the repair. The iPhone 11 Pro battery has two connectors, one on the logicboard and one on the lightning connector. The procedure is the same for both connectors:

    1. First remove the bracket plate over the battery connector by unscrewing the Y-type screws.

    When detaching connectors, always start from the side where there are no small components on the board. 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.
  7. Detaching the display connectors

    • 6 × 1.16 mm Y-Type
    • Connectors

    To be able to remove the display completely, the display connectors are detached from the logicboard. Removing the display makes it easier and safer to replace the battery, because the flex cables of the display are no longer in the way.

    1. First remove the bracket plate over the display connectors by loosening the Y-type screws.
    When detaching connectors always start from the side where there are no small components on the board. This way you avoid potential damage.
    1. Drive a spudger under the three connectors and carefully lift them off the logicboard one after the other.
    2. Then put the detached display to the side.
  8. Detaching the Lightning connector

    • 2 × 1.3 mm Y-Type
    • Connectors

    The battery of the iPhone 11 Pro is fixed in the case from three sides with adhesive tape. To make it easier to remove the adhesive strips, we recommend that you first detach the Lightning connector and remove the bracket plate over the Lightning cable set.

    1. Remove the bracket plate over the Lightning connector cable set. To do so, loosen the two Y-Type screws and put it aside.
    When detaching connectors, always start from the side where there are no small components on the board. This way you avoid potential damage.
    1. Then separate the two connectors of the Lightning connector by carefully lifting them off the logicboard with a spudger.
  9. Removing the Taptic Engine

    • Connector
    • 1 × 4.10 mm Standoff
    • 1 × 1.33 mm Y-Type
    • 1 × 1.75 mm Y-Type

    We also recommend that you remove the Taptic Engine to make the battery replacement easier and safer.

    When detaching connectors, always start from the side where there are no small components on the board. This way you avoid potential damage.
    1. First, detach the Taptic Engine connector by carefully lifting it off the USB board with a spudger.
    2. Loosen the three screws that hold the Taptic Engine in place.
    3. Eventually you can remove it from your iPhone.

    Used tools

    The battery is glued in with three adhesive strips. These can be pulled out by their tabs, which are attached to the edge of the battery.

    1. To begin, remove the black tabs of the adhesive strips from the edge of the battery using tweezers.
    Hold your phone and the battery firmly while pulling the last adhesive strip so that the battery cannot fall out of the device.
    1. Pull the adhesive strips slowly one after the other from under the battery. Pull them out as flat as possible so that they do not tear.
    If one of the adhesive strips tears, you must carefully lever the battery out of the rear case without bending it with the help of a flat, stable tool. We use either a battery spudger or the flexible iPlastix for this purpose.
    1. When all the adhesive strips are released, you can remove the battery.

    2. Then press the battery firmly onto the bottom of the rear case.
  14. Inserting the Taptic Engine

    • 1 × 4.10 mm Standoff
    • 1 × 1.33 mm Y-Type
    • 1 × 1.75 mm Y-Type
    • Connector

    After the new battery is installed, the Taptic Engine can be inserted again.

    1. Place it in its original position at the bottom of the rear case and fix it with the screws.

    Never use force when connecting connectors. Damage to a connector or slot can cause a whole component to fail

    Always make sure to use the correct type and length of screws, otherwise damage to the device may occur.
    1. Afterwards, reattach your connector on the lightning connector by carefully pressing it until it clicks into place audibly and perceptibly.
  15. Attaching the Lightning connector

    • Connectors
    • 2 × 1.3 mm Y-Type

    Also reconnect the Lightning connector and fix its cable with the cover plate.

    1. Attach the two connectors on the logicboard by gently pressing them until you hear and feel them click into place.
    2. Position the bracket plate over the flex cable and screw it to the edge of the rear case.
  16. Attaching the display connectors

    • Connectors
    • 6 × 1.16 mm Y-Type

    At this point you can reconnect the display to the logicboard.

    1. Lean the display back against a stable object to avoid overstretching the flex cables when connecting them.

    Never attach connectors by force. Damage to a connector or the slot can lead to the failure of an entire component.

    1. Attach the three display connectors by carefully pressing them one after the other on the logicboard.
    2. Position the bracket plate over the attached connectors and fix it with the six Y-type screws.
  17. Attaching the battery connectors

    • Connector
    • 4 × 1.46 mm Y-Type
    • Connector
    • 2 × 1.15 mm Y-Type

    After the display, the battery can be reconnected as well. You should always connect it last to avoid short circuits during the repair. The procedure is again valid for both battery connectors:

    1. Carefully press the battery connector on the board so that it clicks into place audibly and noticeably.
    2. Position the bracket plate over the connector and screw it on.
  18. Testing your iPhone 11 Pro

    To make sure that the repair was successful, we recommend that you test your device before you glue and screw it back together. For this purpose use our checklist again.

    If something went defective after the repair, check again if everything is properly installed and connected.

  19. Installing the display
