We will start by removing the SIM / SD tray to be able to remove the case later.

To unlock the back shell, we introduce an opening tool between it and the frame. By making lever movements around the contour, we will be able to release the notches that hold it.

We remove the shields from the board to disconnect the interconnection flex, the battery and the flex from the screen.

To finish, we use a flat tool to pry and take off the battery.
