37 steps
  1. Switching off your iPhone 7

    iPhone 7 - Switching off your iPhone 7 01
    iPhone 7 - Switching off your iPhone 7 02
    iPhone 7 - Switching off your iPhone 7 03
    1. In order to protect your device from short circuits during repair, you should switch it off completely beforehand.
    2. Press the sleep/wake button until the "Switch off" slider appears on the display.
    3. Wipe the slider from left to right.
    4. Your iPhone will shut down completely in about ten seconds.
  2. Removing the rear case screws

    • 2 × 3,3 mm Pentalobe
    1. Use a Pentalobe screwdriver to remove the two Pentalobe screws located to the left and right of the Lightning connector.
    2. Place the loosened screws in a screw storage.

    To avoid losing any of the disassembled parts or screws, we recommend that you use a screw store. You can use an old sewing box for this purpose. We at iDoc use a high-quality magnetic mat for our repairs, on which the removed parts can be arranged in the same way as they were installed in the phone.

  3. Heating up the display

    iPhone 7 - Heating up the display 01

    Used tools

    iPhone 7 opens from the display. This is strongly glued to the rest of the case and must be warmed up before opening.

    1. First place your iPhone 7 on a clean, soft surface to protect the back cover from scratches.
    2. Using a hot air tool, such as a heat gun or a regular hairdryer, run it over the edge of the screen from the outside to heat the adhesive.

    As a rule of thumb, heat your device only enough to make it comfortable to touch without burning your fingers.

    Used tools
  4. Lifting up the display

    Used tools

    Once the iPhone 7 is opened, the warranty for dust and splash protection as well as waterproofness is void.

    1. Once the display edge is well heated, you can place a suction cup on the display at the height of the home button.
    2. Pull the suction cup upwards to create a narrow gap between the aluminium frame and the display.
    3. At the same time, insert a flat, stable tool into the resulting gap. We use a hard plastic plectrum for this purpose.
    4. Try to enlarge the gap by pushing the aluminium frame down with the tool.
    Used tools
  5. Detaching the display

    Used tools

    Be careful not to insert the picks too far on the side of the sleep/wake button, to avoid damaging the flex cable of the display.

    1. Now move the pick once around the display and slightly lift the display up so that the noses come off the aluminium frame.

    Keep heating the edge of the display and leave individual flat picks in the frame, so that the glue doesn't rebond in the already loosened areas.

    Avoid laying the display flat, otherwise the sensitive flex cables can easily be overstretched. We therefore recommend leaning the display against a stable object.

    1. Once the display is completely detached, you can carefully flip it open towards the sleep/wake button.
    Used tools
  6. Disconnecting the battery connector

    • 1 × 2,4 mm Y-Type
    • 3 × 1,0 mm Y-Type
    • Battery connector

    Loosen the battery connector at the beginning of the repair. This will help prevent a possible short circuit and ensure that you don't accidentally turn on your iPhone 7 while you're working.

    1. Use a Y-type screwdriver to loosen the four Y-type screws and then remove the bracket plate over the battery connector.
    When detaching the battery connector start from the side where there are no small components on the board. This way you avoid potential damage.
    1. Now move a plastic lever tool under the exposed battery connector and carefully lift it off. We use a plastic spudger for this purpose.

    The battery is attached to the inside of the back cover with two adhesive strips. These can be pulled out by their tabs, which stick to the lower edge of the battery.

    1. First, use tweezers to remove the tabs of the adhesive strips from the battery surface.

    Hold the battery and iPhone firmly while pulling the last adhesive strip to prevent the battery from falling out of the device.

    1. Slowly pull the adhesive strips one after the other from under the battery. Keep them as flat as possible to avoid tearing.

    If one of the adhesive strips tears, we recommend that you use a battery spudger to carefully lever out the battery.

    1. Once the adhesive is removed, you can easily remove the battery from your iPhone 7 with your fingers.
  11. Removing the speaker

    • 2 × 1,3 mm Phillips
