We apply heat to the back shell, and with a fine enough tool we will open a small hole through which we will introduce one or more plastic spikes, and thus there will be less risk of scratching the shell.

We disconnect the flex bridge that connects the fingerprint reader and the motherboard.

We remove the eleven Phillips screws (PH # 00) that hold the intermediate casing, and with a flat tool we will unhook it.

We disconnect the battery to work with greater security.

With tweezers we will unhook the plastic cover that covers the push buttons, with the help of a fine tool we will detach the flex, and with a slightly more robust tool we will make a small lever from inside the hole to unhook the keys.
