Angle the rear case half away from the top of the front case half, pivoting the hooks out of their clasps.

Caution: Do not fully separate the halves. There is an antenna ribbon connected to the logic board from the back cover.

Disconnect the antenna ribbon cable from the logic board at the Zero Insertion Force (ZIF) connector. The brown portion of the connector lifts up to release the cable end.

The Back Cover is now removed. Congratulations.

Remove the connector for the earpiece speaker, located on the upper end of the logic board.

Turn the front cover over, gently prying the logic board away from the front cover. It will remain attached by two wires from the front of the board.

Work the microphone out of its socket on the front cover; it will remain attached to the logic board, its wires are soldered.

The logic board is now removed from the phone. Congratulations.

Turn the front cover over and shake the keys out of it. They should come free in a single piece.

Note: The keypad may accidentally come free while removing rear cover or logic board. It is best to remove the logic board to reinstall the key mat.

The key pad is now removed from the phone. Congratulations.
