    • Carefully remove the board from the device by gently pushing on the screen from the front side. The battery, screen, and scroll wheel are all connected to the logic board. Be sure to support these components so they do not break.

    • Note the placement of two additional rubber pieces that cling loosely to the logic board. It is okay to let these pieces fall loose.

    • One is located below the scrollwheel.

    • Another is located behind the screen.
