Using a Phillips #00 screw driver bit, remove the 11 screws holding the plastic covers, loudspeaker, and NFC antenna on.

Using a guitar pick to break some light adhesive, remove the top two plastic plates, and the NFC antenna.

NOTE: If the adhesive is too strong, try applying more heat.

Remove the loudspeaker assembly. You may have to peel up a small piece of gold/copper tape holding the assembly to the battery.
