Use the tip of a spudger to pry up and disconnect the screen press connector.

Repeat this process for the front sensor press connector.

During reassembly, align each connector carefully over its socket and press down with your fingertip or flat end of a spudger—first on one side, then the other—until it clicks into place. Don't try to force the connector into place. If you're having trouble, reposition it and try again.
