  • 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

  • Check for clicking sounds as you are prying the back cover away from the frame

I don't think it is necessary to remove the three 0.5mm screws. Note: the right-most orange circle should be placed instead of the red circle above the two larger orange circles - those are the 0.5mm screws which secures a small plate under the plastic cover which is in NOT physically (but electrically via two metal contacts) to the mainboard.
