Peel up the black tape securing the silver ground strap to the metal framework.

The ground strap is very fragile. Be sure not to break it.

Turn the iPod over and peel the orange click wheel ground tab up from the metal framework.

Be sure to detach only the thin ground tab, not the wider click wheel ribbon.

Carefully push the logic board away from the metal framework. Use the squares as indicators of where to push. The logic board is secured to the framework with mild adhesive; be careful not to bend the logic board by pushing too much in any one spot.

The framework should now be free from the rest of the iPod.

Use a small iPod opening tool to flip up the black plastic tab holding the orange click wheel ribbon in place. The black tab will rotate up 90 degrees, releasing the ribbon cable.

Use a small iPod opening tool to loosen the click wheel cable from the logic board. Be careful not to bend the cable too much, or the electronics on the cable could be damaged.

Disconnect the click wheel cable from of its connector, and lift the entire click wheel assembly away from the logic board.

The click wheel should now be separate from the rest of the iPod.

Use a small iPod opening tool to flip up the brown plastic tab holding the orange hard drive ribbon in place. The brown tab will rotate up 90 degrees, releasing the ribbon cable.

Slide the orange hard drive ribbon cable directly out of its connector. The cable may be attached to the logic board with some adhesive. If the cable doesn't immediately come free, carefully pull up on the cable to loosen the adhesive.

Logic board remains.
