Using your thumb, slide the back panel away from the camera to expose the battery.

Grip the battery on its sides, opposite the direction of the white arrow.

Pry the battery up. It will pivot at the end with the white arrow. The battery will now be free.

Remove the 6 outer screws.

• The screws should be 3.5 mm in length.

Put the screws in a safe place as they are very small and easy to lose.

Snap off back the cover by gently prying around the top and bottom edges with a flat head screwdriver.

• It may help to slide the touchscreen upwards when removing the back panel.

The side buttons will become loose and are prone to fall out, so put these in a safe place.

Remove the back speaker by carefully lifting it up.

The speaker will still be attached to the circuit board by a wire and a small piece of clear plastic.

Disconnect the speaker by lifting the clear plastic piece at the end of the wire.

To free the circuit board, remove the black wire that is holding it down.

• You can remove the wire by gently prying up the gold terminator that is attached to the green circuit board. A gentle tug is all it will take.

The circuit board will still be held on by a blue and black ribbon that is removed by gently pulling it upwards.
