Steps:
- Remove the two 3.5 mm Phillips #00 screws from the bottom of the device.
- Caution: Ensure the device is off and unplugged if using the power adapter, as it is unsafe to remove the cabinet while on and will cause damage and potential harm to the user.
- Open the lid, and carefully remove the two 9.7 mm Phillips #0 screws from the inside of the front cabinet.
- Exercise caution while removing these screws, as damage to essential parts may occur and other minor damages may occur if the screwdriver slips.
- Open the battery cover, and gently remove the back cabinet with the iFixit Opening tool.
- The device will make a popping sound when removing the back cabinet. The back cabinet may feel as if it is not loose. However, as long as the back cabinet looks disconnected from the lid, it is safe to remove.
- Carefully desolder each connection and gently remove each connected wire.
- If you are unfamiliar with desoldering and soldering, please consult the iFixit Soldering Guide.
- Make sure the soldering iron is 50 watts as 30-40 watt soldering irons will not melt the solder on the PCB.
- Carefully desolder the next set of connections and gently remove the connected wires.
- Carefully desolder the last two groups of connections and gently remove the wires.
- Caution: Desolder all three marked connections at once before attempting to remove the wires, as they will not fully disconnect and cause damage to the device.
- Carefully remove the three inner screws as shown from the circuit board to loosen it.
- Remove the following screws in this order:
- A 3.4 mm Phillips #00
- A 4.6 mm Phillips #00
- A 9.7 mm Phillips #0. To remove this screw you must lift the PCB at the same time.
- Lift the PCB from the device.
- Make sure not to pull out any wires while lifting the board, as it could cause damage to the device.
- The PCB will already be desoldered from the motor (done through the steps to remove the PCB). Remove the belt from the motor by pulling the belt out and away from the motor and the gear it is around.
- Remove the two 1.9 mm screws with a Phillips #00 screwdriver.
- Remove the motor from where it is seated.
