Step 2 Screws and SIM cards

To begin, with the help of the tool that should bring the phone or other fine-tipped tool, we will remove the tray where the SIM card is located.

When we remove the tray we can see the two Phillips screws (PH # 00) that hold the case.

Step 3 Back case

With a plastic tool we will leverage to release the notches that hold the case.

Step 4 Internal housing screws

We will proceed to remove the intermediate casing that is held by eight phillips screws (PH # 00). This housing is attached to the NFC antenna so we will not remove it yet.

Step 5 NFC housing and antenna

Take off the antenna of the battery to be able to remove it next to the intermediate housing.

Step 6 Disconnect components and screws from the motherboard

We will disconnect all the components of the motherboard and then remove the two Phillips screws (PH # 00) that hold it.

Step 7 Removing the motherboard

We lift the plate carefully and disconnect the flex from side buttons.

We remove the Phillips screw (PH # 00) that holds the flex of the sensor.

Step 8 Flex with proximity sensor

We take off the flex with care since below is the flex of the touch screen.
