    1. Place your iPhone 7 on a clean, soft surface. This will protect the back of your iPhone from scratches.
    2. Have a suction cup, a hard plastic plectrum and a hot air device (a normal hairdryer will also work) ready. With this you can lift off the display. If the glass is broken very badly, you should also use parcel tape - tape off the whole screen before you continue.
    3. The screen is glued to the frame. To loosen the glue, use a hairdryer and heat the outside edge to about 60°C (140°F).

    You may have to repeat this step several times. On the side on which the standby button is located are the Flex cables of the display. Additionally, the display unit is hooked to the edge of the earcup. Once the iPhone is opened, the warranty for dust and splash water protection of the IP67 classification is no longer valid.

    1. If the edge of the display is well heated, you can place the suction cup above the Home button. If this is not possible, place it next to it. Now lift the front screen using the key ring on the suction cup. At the same time, insert the hard plastic plectrum between the screen and the aluminium case and press the case down.
      The display is completely glued. Therefore, the plectrum must be led completely around the iPhone. Be careful not to insert the hard plastic plectrum too far into the device on the side of the standby button to avoid damaging the flex cables of the display.
    2. Now lever the display upwards using the plectrum. This will release the lugs from the aluminium frame. Then you can open the display to the side.

    Never fold the display more than 180° to avoid overstretching the sensitive flexible cables. So don't lay it flat, but lean it diagonally against a stable object. Alternatively, you can use the iHold Evo tool to hold the display securely.

    • Battery Connector

    At the beginning of the repair, loosen the battery contact. 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. Using a Y-type screwdriver (Y000), remove the four Y-type screws and then lift the cover. Place all the parts in a common field of the magnetic mat.
    2. Now you can carefully lift off the battery contact. Use a plastic spudger and go under the plug very gently. If you don't have a suitable tool at hand, you can also try it with your fingernail.

        We will show this step using iPhone 8 as an example; the process is the same for iPhone 7.

        1. Remove all adhesive remains from the metal frame and the display. This will ensure that the new adhesive frame will fit properly.
        2. Remove the first protective film from the adhesive frame.
        3. Now attach the adhesive frame - first on one side, then gradually apply it to the whole device. Only when you are convinced that the frame is in place you should press the frame down with your fingers.
        4. Remove the remaining protective film.

        The corners of the adhesive frame are shaped differently and thus give you an orientation for the correct positioning.

        Although you apply a new adhesive frame onto your iPhone 7, it won't be 100% waterproof after repair.

        1. Put the display on the side of the frame and lower it onto the iPhone.
        2. Push the display toward the Sleep/Wake button so the tabs click into place.
        3. Then press the entire display into the frame.

        We can’t guarantee that it will still be waterproof. You’d have to reglue the display to make sure of that.

        1. Now fasten the last two Pentalobe screws left and right of the Lightning connector.
      31. Setting the time

        iPhone 7 - Setting the time  01

        If your iPhone is disconnected from the battery, it automatically resets the time to "1:00 am on 01.01.1970". This may cause problems connecting to cellular networks.

        To solve this problem, you should connect to a WLAN network after the repair. With an existing Internet connection, the time will come back on its own. If this does not work, remove the SIM card and reinsert it. Alternatively, it may help to switch the flight mode on and off again.
