CNMO were also the ones to dismantle the Xperia Z1, which we reported on back in September 2013. Obviously, apart from the 5.2-inch screen size of the Xperia Z2, the design remains largely the same as the Xperia Z1.

The Xperia Z2’s rear is also made of glass, much like the Xperia Z1. The process to remove the back shell remains the same.

To remove the back shell, you need to use a very thin metal bar, or something equivalent, to pry the bottom of the shell open. The rear shell is glued on, so you will need to gently poke the glue and then move across to pry the bottom open.

Do not rush the procedure, be very patient. This will take some time to do. Use your thin metal bar to pry open all sides to successfully remove the rear shell.
