15 steps
  1. Turning off your Device

    1. Turn off your iPhone 6 completely to avoid damaging it during the repair.
    2. Press the standby button for about three seconds until the slider appears.
    3. Wipe it to completely shut down your iPhone. This can take about ten seconds.
  2. Removing the enclosure screws

    1. To open the iPhone 6 you should use a pentalobe screwdriver.
    2. On the lower side of the body you will find two Pentalobe screws. They are located left and right of the Lightning connector. Remove them and place them in one square on your magnetic pad.

  3. Lifting the screen

    iPhone 6 - Lifting the screen 01

    iPhone 6 - Lifting the screen 03
    1. Lay your iPhone 6 on a soft, clean surface to avoid scratches on the backcover.
    2. With a suction cup and a hard plastic plectrum, you can lift the front screen of your iPhone 6. If the screen is heavily cracked, you should tape it entirely before lifting it. This way you can protect yourself from small glass splinters.
    3. Place the suction cup on the display - if possible directly above the Home button, alternatively next to it (see figure 1). Use the ring on the suction cup to lift the screen. At the same time, press the pletrum between the aluminium and display frame, pushing the aluminium frame downwards. This way you can lift the screen with the plectrum (see figure 2). This step requires some patience - you will probably need several attempts.
    4. When you have succeeded and the display can be lifted a little bit, work your way carefully on the outside until the two long sides are loosened (see figure 3).
  4. Disconnecting the battery connector

    After lifting the screen you should disconnect the battery contact. This way you can avoid a short circuit during the repair. It also helps ensure that your device does not accidentally turn on during repairs.


    1. Use a Phillips screwdriver to remove the Phillips screws that are attached to the battery connector (see figure 1). Take off the cover (see figure 2) and put all parts in the same container.
      1 x 3.2 mm Phillips screw
      1 x 2.3 mm Phillips screw
    2. Now carefully remove the battery connector. To do this, use the sharp end of the ESD spudger - go very gently under the plug (see figure 3). You do not have a spudger available? You can also try to remove the plug with your fingernail.
  5. Disconnecting the display connectors

    1. The silver cover is fixed with five Phillips screws. Remove them (see figure 1) and place the screws in one section of the magnetic pad. Then you can remove the cover.
      1 x 3.1 mm Phillips screw
      3 x 1.3 mm Phillips screw
      1 x 1.8 mm Phillips screw
    2. Now you see four overlapping connectors (see picture 2). Loosen them very carefully in the order shown below. To do this, gently go under the contact with the pointed side of the spudger and lift it up.

    1. The battery sits firmly in the body due to two adhesive strips. With your spatula you can loosen the two black ends of these from the battery (see figure 1).
    2. Now remove the adhesive strips. Therefore you have to work very slowly and keep the strips as flat as possible, at the height of the iPhone (See figures 2 and 3).
    3. Now take off the battery from the iPhone 6.

    1. To make sure your new battery fits securely inside your iPhone, you should apply new adhesive tape to the bottom of the battery.
    2. To do that, remove the blue protective film first.
    3. Now apply the adhesive tape to the back of the battery, taking care not to leave any tabs overlapping.
    4. Next, remove the small blue films from the black tabs and stick them to the edge of the battery.
    5. Remove the last remaining protective film. Now your battery is ready for the next step.
  10. Installing the battery

    1. Now attach new adhesive strips on the bottom of the battery so that it does not move in the future.
    2. Insert the battery into iPhone, but don't connect it with your device to avoid a possible short circuit.
  11. Installing the vibration motor

    1. Put the vibration motor back in its original place (see figure 1).

  12. Connecting the display

    1. Now attach the LCD connector (see figure 1). This usually requires several attempts. So no worries if it does not work the first time. However, it is important that you are extremely careful in your attempts so that the plug cannot be bent.

    2. When the connectors are attached securely, you can turn on your iPhone 6 again! Run a few functional tests and see if the LCD, touch screen, proximity sensor, front camera and earcup still work.
      If you see streaks on the display or the touchscreen is partially not working, the connectors are not connected properly.
    3. Put the cover on the connectors and fix it with the five screws (see figure 2).
      1 x 3.1 mm Phillips screw
      3 x 1.3 mm Phillips screw
      1 x 1.8 mm Phillips screw
  13. Connecting the battery

    2. Put the silver cover into the case and fix it with the screws.

  14. Attaching the display

    iPhone 6 - Attaching the display 01
    1. You're nearly there! Carefully put the display back into the housing. Be careful not to pinch any cables and make sure that the edge at the top of the screen really clicks into place.
    2. Now carefully push your screen on towards the home button so that it fits correctly in the frame.
  15. Fastening the enclosure screws

    iPhone 6 - Fastening the enclosure screws 01
    1. Take the last remaining Pentalobe screws and insert them into the lower side of the body.
      2 x 3.8 mm pentalobe screw
  16. Setting the time

    iPhone 6 - Setting the time 01

    Because the battery was disconnected from the iPhone 6 for a while, it is possible that the time is no longer set correctly and is now automatically set to "1:00 am 1/1/1970". This may cause problems with the connection to the cellular network.

    Connect your iPhone 6 to a wireless network to resolve this potential problem. When your device is connected to the Internet again, the time should reset itself. If it doesn't, try removing and reinserting the SIM card. Alternatively, it may help to turn Flight Mode on and off.
