In the top there is a connector where you have to lift the black part of the connector to remove the ribbon. I used tweezers to lift the connector and to remove the ribbon cable

Once the top ribbon is removed there is another cable connected in the middle. The phone will open up more to give you access. You will need to lift the black part of the connector to remove the ribbon. Again, I used tweezers. The screen assembly should now come away from the chassis
