Introduction

You dropped your iPhone X in the water and want to remove the logic board to clean or repair it? In this tutorial, we'll show you how to remove the motherboard from your iPhone.

After liquid damage, we recommend that you clean the board to prevent further corrosion.

For each step there is a small video sequence that shows you exactly how to proceed with the repair. The videos can always be started via the play button on the right corner in the first picture at each step.

Since the glass itself is very difficult to remove, we recommend replacing the entire unit consisting of the stainless steel frame and the rear glass.

Make a backup of your iPhone before repairing it.

Be particularly careful when loosening the front camera and FaceID unit and the earpiece, as these cannot be replaced without losing the FaceID function.

17 steps
  1. Switching off your device

    1. Turn your iPhone off completely to avoid damaging it during the repair. Press and hold the Standby button and one of the two volume keys for three seconds, until the "Power off" slider appears.
    2. Swipe the slider from left to right. Now your iPhone will shut down completely, which can take about ten seconds.
  2. Removing the back cover screws

    • 2 × 6,8 mm Pentalob

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

    1. Remove the two pentalobe screws at the bottom edge of the back cover. They’re to the right and left of the Lightning connector. Put the screws in the same box of your magnetic pad.
  3. Removing the display

    1. Put your iPhone X 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 steel frame and the display frame and press down the steel frame.
    Do not insert your tool more than 5 mm into the gap, so you don't damage small parts inside the iPhone.

    If you are using an iFlex, switch to a plastic pick as soon as possible to avoid scratching the frame.

    1. 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 display flex cables.
    2. Now use the pick to push up the display so the tabs disengage from the steel frame. Then you can fold the display over to the side.
    3. Rest the display on a stable object to avoid straining the sensitive flex cables.

    Heat the outer edge of the frame several times if necessary.

    After being opened, your iPhone X loses its guarantee for dust and spray water protection (IP 67 rating).

    • 1 × 3,0 mm Y-Type
    • 3 × 1,0 mm Y-Type
    • 1 × 3,6 mm Y-Type
    • 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 Y-Type screwdriver (Y000) to remove the Y-Type screws. Then take off the bracket plate. Put all the parts in the same box of your magnetic pad.
    2. Note that the screws have different lengths

      Apple introduced Y-Type screws with the iPhone 7. They are often wrongly called Tri-Point or Tri-Wing. Use a matching Y-Type screwdriver for these screws so you don't strip the screw heads.

    3. Now very carefully pry off the battery contact by inserting a spudger under the connector.

    2. Use a spudger to separate the connectors for the display and the earpiece one by one.
    3. Be very careful when prying off the connectors using the spudger to prevent damaging anything.
    4. If all connectors are off, you can remove the display. There may still be glue residue on the frame and display.

    3. Secure the logic board by inserting the screws.
    4. Then connect all connectors. Take your time and proceed carefully. Position the connectors above their positions on the logic board and press carefully. The contacts should engage slightly. Don't slide the plugs back and forth and try not to push them tight with force. Use a spudger for the small plug at the top to push it down.

    2. Remove the first protective film layer of the frame sticker.
    3. Position the frame sticker carefully on one edge of the frame and attach it gradually. Make sure the frame sticker is positioned evenly and press it on. You can use the plastic spudger to press the adhesive on.
    4. Remove the next large protective film.
    5. You can leave the small protective films on for now and remove them when you've connected the display and attached the bracket plates. This prevents anything from sticking to the frame sticker before you install it. But you can also remove the films right away.

    Please make sure the frame sticker is positioned correctly. Each corner has a different shape, which you can use for orientation.An iPhone repaired with a frame sticker will be protected against dust and spray water, but it will not be 100% waterproof!
