We will start by removing the back cover. With an opening tool, preferably plastic to avoid damaging it, we will unhook the notches that hold it.

To remove the battery, we can use the opening tool. Introducing this by the notch that the battery brings, it will be easy for us to lift it.

To remove the SIM and SD cards, we simply have to pull them.

To remove the intermediate housing remove the eleven Phillips screws (PH # 00). Now, with the help of an opening tool and a suction cup to better grip the mobile, we will separate the chassis housing.

You have to be careful when removing the chassis since we can take off the screen. Make sure you see that what comes out is the chassis.

In order to remove the motherboard, we will disconnect the components. We disconnect the flex from the screen, the front camera and the audio connector.

With the components already disconnected, we will disengage the plate from the hooks of the chassis.

To remove the flex, first we will remove the rubber that covers it. Now we just have to take off the flex of the chassis and remove it by sliding it through the hole in it.
