Description:
Steps:
- Use a spudger to disconnect the Lightning connector ribbon cable from its socket on the logic board.
- The Lightning connector cable is lightly adhered to a shield on the logic board. Use the flat end of a spudger to gently peel the cable up.
- Flip the Lightning connector cable up out of the way of the logic board.
- Disconnect the lower antenna connector from the base of the logic board.
- Use the flat end of a spudger to disconnect the audio control cable connector from its socket on the logic board.
- Disconnect the rear-facing camera cable connector from its socket on the logic board.
- A small piece of tape may obscure the logic board grounding clip. If so, use a pair of tweezers to remove the tape.
- Remove the following screws securing the logic board grounding clip to the rear case:
- 1.2 mm Phillips #000 in the top side-wall
- 2.5 mm Phillips #000
- Use tweezers to remove the logic board grounding clip.
- Remove the following screws securing the logic board to the rear case:
- Two 2.3 mm Phillips screws
- Three 2.7 mm standoff screws
- Standoff screws are best removed with a standoff screwdriver or standoff driver bit. A small flathead screwdriver can also do the job—but use extra caution to ensure it doesn't slip and damage surrounding components.
- Holding the phone level, lift the bottom end of the logic board up enough to grasp it with your fingers.
- Pull the logic board away from the rear-facing camera just enough to expose the gold contact cap under the top end of the board.
- Remove the gold-colored contact cap from the threaded post in the rear case, and set it aside.
- Flip the logic board up toward the volume control buttons to expose the antenna connector.
- Do not try to remove the logic board from the rear case yet, as it is still connected by an antenna cable on the back.
- Disconnect the antenna connector from the back of the logic board.
- Remove the logic board from the rear case.
