To remove the back cover, we introduce an opening tool between the frame and the housing. By leveraging we will be able to unhook it.

Remove the adhesives that cover the base plate.

Now we disconnect the cameras and the interconnection flex and desoldamos the microphone.

We desoldered the battery, the speakers and the coaxial antenna cable.

Finally, we desoldered the Hall sensor and the side buttons. Now it would only be necessary to remove the screws that hold the base plate and disengage it.
