Tools required for disassembly: iPhone tool kit, needle/paperclip or something similar.

  • First push your sim removal tool into the hole at the top of the phone. This will release the sim holder. If you don't have the original tool, use something like a paper clip.

  • You should now have the sim holder removed. Tip the phone up and you'll see two screws, circled below. Remove these.

  • Now attach a suction cup (comes supplied with our iPhone tool kit) near the bottom of the screen. If the screen is badly damaged, attach the suction cup to an area of the screen that is less damaged as this will help the suction cup grip better. Lift the suction cup up and the screen will raise up. You need to lift the bottom end of the screen as it is still attached by ribbon cables near the top.

  • You can now access a number of ribbon cables. The two circled, numbered 1 and 2, attach like a plug and socket. Just lever the connectors up, away from the circuit board, to unplug them.

  • You should now have access to the third ribbon cable. This is slightly different from the previous two and is called a zif connector. The black part opens and closes on a hinge. Flick this part over, towards the ribbon, and the ribbon will be free and you can pull the complete screen away from the rest of the phone.
