We start by removing the back cover. For this we can heat it to about 60ºC for about a minute. When it is hot, we introduce an opening tool to detach it and at the same time unhook it from the notches that hold it.

To remove the intermediate casing, first remove the seven Phillips screws (PH # 00) that hold it and then pry it off.

Finally, we disconnect the battery and take it off. To detach it, we will pull the black tabs that it brings in the lower part to remove the adhesive.
