To begin with we will have to remove the back cover. With the help of an opening tool, making lever movements, we will unhook the housing from the notches that hold it.

To remove the battery, we will disengage it by using the opening tool or simply with your fingers.

Before removing the intermediate housing we will remove the SIM and SD cards. To remove the SD card we can pull it with your fingers. To remove the SIM card, we will introduce a tip tool through the hole that it brings for the extraction.

After removing the eight Phillips screws (PH # 000) we will begin to unhook the notches that hold the casing to the chassis. Making lever movements, if possible from inside to outside, will be released.

The casing is well attached to the chassis, so we'll have to be careful. We must not forget the internal notches that are in the one where the battery was and that we will have to separate with care since they can be hooked on the base plate.

We only have to release the key of the hooks of the intermediate casing.
