    • Make sure you remove the battery first. You will see that there are 14 screws on the back of the inner case. Use the Phillips head screwdriver to remove each of the screws, make sure to put the screws in a safe place where they will not get lost.

    • Once you have removed all the screws, you can begin removing the inside cover.

    • Insert the opening tool using a sliding motion into one of the corners and move it along the edges of the inside cover. This will loosen the edges and the inside cover will pry apart from the shell.

    • In this next step it is easy to pry the wrong piece. Make sure to pry at the metal platform that the sister board sits on, not the orange printed circuit board itself.

    • Using your prying tool, pry at the right red marked corner, making sure to pull at the metal platform under the circuit board. Once it is raised slightly, pull along the underside until the left red mark. This should loosen the board and allow it to be removed.

    • If it's still unable to be removed, try to pry at the orange mark, making sure to pull at the same metal platform.

    • The logic board is connected to the under side of the phone with a bit of adhesive. Using a spudger, place it under the logic board from the top right corner and gently slide it toward the center orange mark where the adhesive is. Apply a little bit of pressure parallel to the logic board and the Logic board should loosen from the phone.
