iPhone 3GS Repair DIY Instructions

Taking the iPhone apart

  • Step 1

    Turn off the iPhone. Remove the SIM card by inserting a paper clip into the small hole at the top. Remove the two screws at the bottom. Push the suction cup onto the glass. Pull up to separate the glass.

  • Step 2

    Three cables will hold the two pieces together. Remove the first two using a paper clip. The third is beneath a tab under the first two cables. The last cable should be pulled out gently.

  • Step 3

    On the screen, remove six screws: two on one side, one on the bottom of the surface behind the glass, one visible on the other side and two under tape on that side.

  • Step 4

    To remove the LCD, use a paper clip on the sides to hook the bottom corner that has a circle, and pull out.

     

    Removing the broken glass

  • Step 1

    Using tweezers, remove the black tape behind the glass on each of the four edges.

  • Step 2

    Use a hair dryer around the edges of the glass for about 5 minutes to heat the glue.

  • Step 3

    Pry the glass from the plastic holder. Be sure to remove all the broken glass.

     

    Installing the glass

  • Step 1

    Put the adhesive strips at the top and bottom of the plastic holder.

  • Step 2

    On the new glass screen, remove all the film from the black bottom and top, leaving the protective film on the glass so no fingerprints will get inside. There will probably be two pieces of film on the black parts.

  • Step 3

    Line up the glass with the holder, making sure the cable goes under the holder. When the two pieces match up, press down to stick the glass to the adhesive strips.

  • Step 4

    Remove the film from the glass.

     

    Reassembly

  • Step 1

    Put the LCD back in the holder with all the holes for the screws aligned. Press it in place. Replace all the screws.

  • Step 2

    Press all the cables into place in the reverse order of their removal.

  • Step 3

    Align the two pieces — the screen and the unit — and press them together with the holes lined up.

  • Step 4

    Replace the screws and your SIM card.
