Use a spudger, opening tool, or a clean fingernail to flip up the black locking flap of the ZIF connector—this is the unlocked position.

Use tweezers or your fingers to gently pull the cable out of its socket by the blue tab.

To disconnect the cable, first try pushing on alternating sides of the JST connector, like small sliding connectors.

If that doesn't work, use a pair of tweezers to firmly grip the sides of the connector and pull straight away from the socket. Hold the tweezers closer to the connector to get a better grip.
