We are now finally at the stage of removing the screen.

Flip the mid frame back over so that you are now looking at the front of the phone again. We will now need to use a hair dryer or heat gun to heat up the edges of the phone to loosen the glue that is holding in the screen and front buttons, to the mid frame

Once the glue has heated up enough you should be able to get a plastic prying tool between the glass screen and the plastic mid frame.

Slowly and carefully move your prying tool around the phone until the screen has been released from the mid frame. I found that the glue that holds the screen to the mid frame is not to strong, which is good.
