  • Using the flat metal spudger and curved metal spudger, make a wedge between the plastic back cover and the inner frame

  • Using the second spudger, slowly work your way around the perimeter of the device

Place the screws on the magnetic mat to avoid losing them. Use a 3.0 Phillip’s head screwdriver to remove the 10 1.2mm Phillip’s head screws in the plastic frame that held the motherboard and battery. Use a 3.0 Phillip’s head screwdriver to remove the 3 0.5mm Phillip’s head screws in the plastic frame that held the motherboard and battery.
