    1. Put your iPhone SE on a soft, clean surface to avoid scratching the back.
    2. To lift the display, you need a suction cup and a hard plastic pick. If the screen is severely cracked, cover all of it with tape before you continue. Risk of injury due to broken glass.
    3. Place the suction cup over the Home button if possible (otherwise, put it next to the button). While lifting the display with the suction cup, use the hard plastic pick to press down the aluminum frame. At the same time, insert the hard plastic pick between the aluminum frame and the display. This usually takes several attempts.
    4. Once a little gap has opened up between these two parts, you can open it further by slightly turning the pick.
    5. As soon as you can lift the display a few millimeters, you have to carefully work your way around the outside until it’s loosened on both sides.Don’t take off the display all the way. You have to disconnect the Home button first.
    6. There’s a metal cover blocking the Home button. Carefully detach the cover using a pair of tweezers.
    7. As soon as the cover is off, you can disconnect the Home button from the flexible flat Lightning cable.

    2. Carefully detach the battery contact using the spudger. Insert the pointed tip of the spudger slightly below the connector. If you don’t have a spudger, you can also try using your fingernail.

    2. Carefully pull the black end of the adhesive strips at a very flat angle to detach the battery. You can also separate the two adhesive strips and then remove one after the other. Hold the battery and your device in place the whole time.The adhesive strips could tear. If that happens, you can heat your device with hot air and then use the spudger to carefully pry out the battery.

    1. You need to put on two new adhesive strips to attach the battery to the back cover. The adhesive strips have to be positioned so the two tips end just before the flexible flat volume cable, and the strips are centered between the logic board and the outer wall opposite it.
    2. Use your fingers to firmly press the adhesive strips onto the back cover so they won’t get stuck on the red film when you pull it off.
    3. Remove the red protective film.
    4. Position the battery so that it’s centered on the adhesive strips. You can also use the black end of the adhesive strips to orient yourself. The battery has to line up exactly with the white adhesive strips. Make sure there’s enough space between the battery and the logic board for the battery connection.
    5. Fold over the black end in the middle.
