We start by removing the SIM / SD tray and removing the lower screws of the housing.

We introduce an opening tool between the frame and the screen. By doing a bit of leverage we will be able to disengage it easily.

In this step, we remove the shield that covers the battery connector to which it is attached. We will be careful when removing it so as not to damage the flex.

We also remove the adhesives that cover the other two connectors.

We disconnected the interconnection flex and the flex of the display. At the top of the plate, we unplug the flex from the digitizer and remove the six Phillips screws (PH # 00) that still hold it.

We can undo the plate. Before removing it, we will have to disconnect the coaxial antenna cable.

Now we will have to remove the receiver, the battery and the lower module with the auxiliary plate and the home button for which you can consult the respective guides.

To unstick the screen of the chassis, you can consult this other guide: https://goo.gl/WgVSMg
