Take off the back cover using one or more plastic tines, if necessary we could apply a little heat to soften the adhesive that holds it.

Remove the fourteen Phillips screws (PH # 00) that hold the intermediate housing, remove the tray from the cards and we can unhook the case.

We disconnected the battery for safety.

To finish we will disconnect all the components that are connected in the auxiliary plate that we have to replace, and we will take it off with the help of a sufficiently fine tool.
