Removing the motherboard

1. The bottom of the motherboard (arrow) is connected to the USB port.
2. Carefully tilt the board up by 180° so you can get at the contact. Don’t pull too hard on the board.
3. Using the spudger, carefully disconnect the contact from the PCB.
4. Remove the board.

There's a small plastic pin in the opening of the SIM tray. Make sure it doesn't fall out.
