24 steps
  1. Removing the enclosure screws

    iPhone 5 - Removing the enclosure screws 01
    1. You need a pentalobe screwdriver to open the iPhone 5.
    2. Remove the two pentalobe screws at the bottom of the enclosure. They are located to the right and left of the Lightning connector. LPut the screws in the same compartment of your organizer tray.
      2 x 3.6 mm pentalobe screws
  2. Lifting the display

    1. Put your iPhone 5 on a soft, clean surface to avoid scratching the back.
    2. To lift the front panel, you need a suction cup and the hard plastic pick. If the screen is severely cracked, cover all of it with packing tape.
    3. Place the suction cup over the Home button (if possible) or next to it (see figure 1). While lifting the screen with the suction cup, insert the hard plastic pick between the aluminum frame and the display frame and press down the aluminum frame. Also use the hard plastic pick to raise the screen (see figures 2 and 3). This usually takes several attempts.
    4. As soon as you can lift the screen a little bit (see figure 4), you have to carefully work your way around the outside until it’s loosened on both sides (see figure 5).
    5. Once the display is fully detached, you can flip it up at the Home button. Note that the display cables are still connected to the logic board (see next step).
  3. Disconnecting the connectors

    iPhone 5 - Disconnecting the connectors 01
    iPhone 5 - Disconnecting the connectors 02
    1. First remove the three Phillips screws from the silver cover (see figure 1). Put the screws in the same compartment of your organizer tray.
      2 x 1.2 mm Phillips screws
      1 x 1.7 mm Phillips screw (not magnetic)
    2. Now you can disconnect the following three connectors (see figure 2). Be very careful.
    3. Place the pointed tip of the spudger very slightly below the contact and lift it up. Make sure you don’t break off the resistors that are soldered onto the logic board. In later batches of phones, the resistors are protected by a black plastic film.

      1 x 1.8 mm Phillips screw (funnel head)
      1 x 1.7 mm Phillips screw
    2. Now carefully lift off the battery connector by inserting the pointed tip of the ESD spudger slightly below the connector (see figure 3). If you don’t have a spudger, you can also try using your fingernail.
  5. Removing the battery

    1. Now remove the battery. It’s sometimes glued firmly in place. Insert the flat end of the spudger into the space between the battery and the logic board, and carefully lift the battery.
      The logic board is very sensitive. You can also lift the battery from the other side.If the battery’s really stuck on, use other leverage points to the right and left of the original spot to pry it off. If you still can’t detach the battery, you can use a heat gun to slightly warm the glue from the outside and soften it.
  6. Plastic tab

    iPhone 5 - Plastic tab 01
    1. Fold the plastic tab with the warning over and press it firmly onto the adhesive strip. This way, it won’t get in the way during your repair.
