Hi! My name is ***** ***** I'm happy to help!
The back is glued on, so you will need a heat gun or hairdryer to melt the glue. Turn your device off before beginning. Apply heat around the bottom of the back cover, careful not to leave the heat source in one place. You'll need a suction cup most likely to pull the back separate from the housing.
