To begin we will have to unhook the back cover, for this we will use a suction cup and a fine tool, once we raise the casing we will be able to introduce some thicker tool. We must be careful with the flexes that are glued to the housing.

We disconnect and remove the two interconnection flexes.

We disconnected the flex from the battery, and removed the four Phillips screws (PH # 00) that hold it.
