Disconnect the SIM card reader cable by carefully pulling it out of the ZIF connector with a pair of tweezers.

Carefully bend the SIM card reader cable upwards to free the logic board.

Do not fold the cable sharply and only bend it to avoid cable damage.

During reassembly make sure the flap of the ZIF connector is in an upright position. Push the cable back into the ZIF connector and fold the flap down afterwards.
