Use the pointed end of a spudger to disconnect the Wi-Fi diversity antenna by prying its connector straight up from its socket.

The socket of this connector sits loosely between the speaker and the Taptic Engine and it's a bit fiddly to disconnect the cable. To make the disconnection easier, you can use an opening pick to hold down the connector socket during this procedure.

Reconnecting this cable can be tricky. Make it easier by using tweezers to hold the flex cable so the connector aligns with its socket. Then, gently press straight down on the connector with the flat of your spudger until it clicks into place.
