Before we start, we will remove the stylus.

Using a plastic opening tool, we will disengage the housing from the notches that hold it.

We must not forget to remove the SIM and SD cards before continuing dismantling.

With the opening tool we will lever the bottom of the battery to disengage it and thus be able to remove it.

To remove the intermediate housing, first we will have to remove the 15 Phillips screws (PH # 0) that hold it. After removing the screws, with the help of a pick or other opening tool, we will unhook the housing from the notches that hold it.

After removing the intermediate housing, we will have access to the antenna cables. Now we just have to disconnect both ends of each cable to be able to remove them.
