9 steps
  1. Switching off your device

    1. Turn off your device by holding down the power button until the “Power off” option appears.
    2. Use your finger to confirm that you want to shut down your device and wait until the screen goes blank.

  2. Remove back cover

    To loosen the back cover, use a heat gun or an ordinary hair dryer. Warm glue is easier to loosen, allowing you to remove the back cover. The easiest way to loosen the back cover is to use a flat and flexible tool such as the iPlastix or iFlex.

    You will also need several picks to unstick the back cover all around.

    1. Heat the spot where you start and place a suction cup on the bottom of the back cover.
    2. Press a flat tool between the back cover and the frame and pull on the suction cup.

    The iPlastix is made of plastic, so it won't scratch the device. On the other hand, it's very soft and tricky to insert.

    Be extra careful, the back cover can break very easily. If necessary, apply the heat several times and try again. Removing the back cover might take half an hour. Take a little more time and work carefully to make sure you don't break anything.

    1. Once the tool is inserted, stick a pick into the gap to keep it open. Then run the tool around the entire edge to gradually loosen the glue.
    2. Then heat the next part and insert the picks one by one.

    The back cover glue is extra strong on the lower edge.

    1. Once the back cover is loosened, lift it very slightly. The fingerprint sensor underneath the camera is still connected with a cable.
  3. Disconnect fingerprint sensor

    1. After detaching the back cover, carefully lift it and disconnect the fingerprint sensor using the spudger.
    2. Then you can completely remove the back cover and set it aside.
  4. Remove midframe

    • 10 × 4.0 mm Phillips

    Then remove all the equally long Phillips screws from the logic board cover and store them together.

    This phone has only two different screw lengths. If some screws don't come off immediately, you can also use a pair of tweezers.

    1. The logic board cover with the NFC tag is latched in at the top.
    2. Pry it up a little and then take it out.
  5. Remove charging coil / NFC

    1. Carefully slide in a steel spatula where the wireless charging coil is glued to the NFC antenna and pry off the contact.
    2. Then unglue the side antenna unit using the spatula.
    3. Now slowly remove the entire flex cable from the cover.

    If the cable is hard to remove, you can use a heat gun to soften the glue.

  6. Attach charging coil / NFC

    1. Reattach the NFC antenna. Use the small plastic pins on the cover to position it correctly.
    2. Press the flex cable to the back of the cover to glue it on.
    3. Now put the plastic cover back on the NFC tag and press it on.
  7. Insert midframe

    2. Latch it in and press it in all around.
    3. Then fasten all the screws again.
  8. Connect fingerprint sensor

    • Fingerprint connector
    1. Before attaching the back cover, plug in the fingerprint sensor connector.
    2. Use a plastic tool to reach the connector.
  9. Attach back cover

    1. Before reattaching the back cover, check the glue. It should be sitting evenly on the back cover. You can remove any excess glue.
    2. Then press on the back cover.
    3. Heat the back cover again to bond the glue.
    4. You can press on the back cover with your fingers while the glue cools down.

    Please note that your smartphone's water ingress protection is no longer the same after you open it.
