Insert the edge of a plastic opening tool under the EMI Shield near the bottom left corner of the Touch.

Pry upward to separate the plate from the adhesive securing it to the plastic inner case.

If the shield is still attached to the logic board, warm this area with a heat gun to loosen the adhesive, then separate the shield from the logic board using the opening tool.

There is a very thin ribbon cable here that connects the volume and power buttons to the logic board. Be careful when prying in this location as the cable is very fragile and could rip.
