    • 2 × 3,3 mm Pentalobe-Schraube

    You need a pentalobe screwdriver (PL1) to open the iPhone 7.

    1. Put your iPhone 7 on a soft, clean surface to avoid scratching the back.
    2. To lift the front panel, you need a suction cup, a hard plastic pick and a heat gun. If the screen is severely cracked, cover all of it with packing tape before you continue.
    3. The screen is glued to the frame. Use a heat gun to heat the outer edges of the display to about 60°C (140°F).
    4. Place the suction cup over the Home button (if possible) or next to it. 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. Because the display’s glued on, you have to slide the pick all around the iPhone between the aluminum frame and the display frame. Don’t stick the pick in too far on the side where the Sleep/Wake button is because that could damage the flexible flat display cables.
    5. Now use the pick to push the display toward the Lightning connector so the tabs come out of the aluminum frame. Then you can fold the display over to the side.
    6. Set the display on the aluminum frame so you don’t stretch the flexible flat cables too much.

    If necessary, heat the outer edges of the display a few times. Don’t forget that the flexible flat cables for the display are on the side with the Sleep/Wake button. The display is also hooked onto the edge of the earpiece.

    • Battery Connector

    Before starting the repair, disconnect the battery contact to prevent short circuits and avoid accidentally turning on your device during the repair.

    1. Use a tri-point screwdriver (Y000) to remove the four tri-point screws. Then take off the cover. Put all the parts in the same section of your magnetic pad.
    2. Now carefully lift off the battery contact by inserting a spudger slightly below the connector. If you don’t have a spudger, you can also try using your fingernail.

      • Front camera bracket (lightly glued in place)
      • Sensor bracket (lightly glued in place)
    2. Peel the protective film off the new display and remove the seals.

    • 6 × 1,0 mm Tri-Point-Schraube
    1. Press down the flexible flat cable. Place the silver rear panel on the back of the new display and screw it in place. Don’t tighten all the screws yet because you still need to position the rear panel.
    There’s still glue on the back of the rear panel, so make sure you place the rear panel exactly over the screw connections.
    1. Once the rear panel’s positioned right, you can tighten the screws.

    The silver looking chip on the cable need to be exactly positioned. Otherwise you will have a spot on the display at this location. If so, adjust the position of the cable.

  22. Setting the time

    iPhone 7 - Setting the time 01

    When the battery is removed from the device, the iPhone loses the time and sets itself to 1:00 a.m. on 1/1/1970. You could have trouble connecting to the cellular network if the time isn’t set.

    After a repair, complete the following steps:

    1. Synchronize your iPhone with iTunes or connect to a WLAN network and wait until the time is set.
      The time won’t be set automatically unless you enable this feature in the settings.
      Settings > General > Date & Time > Set Automatically
    2. Remove the SIM tray with the SIM card and reinsert it.
    3. Activate airplane mode on the device and then deactivate airplane mode.
      Settings > Airplane Mode
