    • Using a plastic opening tool or spudger, pry apart the front case from the back. There are many access points, but the best spot to insert the spudger is around the "TALK" button.

    • Avoid using the metal spudger. When working with electronics, it's important to choose a tool that's ESD-safe to avoid accidental damage to the device. The regular black nylon spudger or a plastic opening tool should be used whenever possible.
