We will start by removing the back support. For this we will slide the pins that we will find in the union with the housing and we can remove it.

In the back we will find a cover, which we will slide to get to the SD card. To withdraw it, we will press and it will be automatically expelled.

In the case we will find four Phillips screws (PH # 00) which we will remove to be able to remove it.

Now, to remove the case, we will leverage with the help of an opening tool. We will slide this between the frame and the casing to release the notches that hold it.

In this step we remove the twenty-four screws that hold the chassis to the frame, to later remove it.

Before removing the chassis, we will have to disconnect certain components. We will disconnect the flex from the touch screen and the LCD display. We will also disconnect the flex that connects with the flexes of the buttons and we will take off the microphone, flash and camera plate.

Now we can remove the chassis with the components.

Now we will heat the screen to soften the adhesive and thus it will be easier for us to take it off later. We will use the heat gun since due to the size of the device, it seems the most appropriate.

With the hot screen, we will slide a prong or other opening tool, all around the contour so that it is detached from the frame.

Finally, we will finish removing the adhesive in the area of ??the flex and then we will slide it through the hole in the frame.

Now, we can remove the four Phillips screws (PH # 00) that hold the display to the frame.
