To be able to remove the back cover, first we will have to remove the two Torx screws (T3) that hold the housing at the bottom and also the SIM / SD tray.
Step 2 Remove back casing
We will introduce a flat opening tool between the housing and the frame. Sliding this around the contour, we will release the notches that hold it.
Step 3 Remove speaker module
Remove the four Phillips screws (PH # 00) that hold the module and unlock it.
Step 4 Auxiliary plate
All that remains is to disconnect the components and remove the chassis plate.
