Remove the six 4.5mm #000 Phillips screws.
Step 6
Forcing the cover may cause cracked plastic.
- Start at a corner using a spudger to pry rear case from front display.
- Migrate spudger towards top on both sides, or use a plastic opening tool for ease.
- When detaching the top, free each side short of center and apply pressure at both corners and center to slide back cover down.
Step 7
Remove and separate the rear case from the phone.
Step 8 | Antenna Cable
Remove the antenna cable from the motherboard using a spudger tool.
- Pry up one end of the cable from the motherboard's connector.
- Next, pry up the other end of the cable from the antenna array's connector.

Use a spudger or plastic opening tool to carefully lift the black NEC chip, which is attached to a ribbon cable.
- Lift the camera assembly gently from the plastic housing.
Step 12 | Motherboard
Careful not to pry against the connector — risk of further damage.
- Use a spudger to slide under highlighted connectors, starting disconnection.
- Pry from underneath up, excluding motherboard socket, for complete disconnection.
Step 13
Use care when handling the motherboard, as it is fragile and easily damaged.
- Support the device with one hand, placing your other hand under the motherboard to prevent it from falling.
- Lift the motherboard upward carefully using your fingers to avoid applying excessive force.
