Step 2 Back case

We start by removing the back cover for what we will use a plastic opening tool. Inserting it between the casing and the frame we can go separating them.

Step 3 Battery and SIM card

We will remove the battery helping us with the opening tool.

If it costs us to remove the SIM card we can push it with a tool.

Step 4 Intermediate housing screws

In this step we simply remove the twelve Phillips screws (PH # 00) that hold the housing to the phone's chassis.

Step 5 Heat screen

In this step we will need to heat the glass to soften the glue and thus be able to remove the screen more easily.

Below we will see two ways to perform this step.

We will use a high thermal retention blanket (HOT GLASS) to heat the glass.

Insert the HOT GLASS in the microwave for the time specified in the instructions.

To heat it evenly, it is necessary to interrupt the microwave every 30 seconds to distribute heat throughout the HOT GLASS with your hands.

The gun emits VERY hot air, use with caution.

We recommend the use at minimum power and short bursts, since excess heat can damage the equipment.

Warm the screen to soften the glue and be able to easily peel it off.

Step 6 Take off screen

With the hot screen, we will introduce a prong between it and the frame to take them off.

Step 7 Intermediate housing

Taking advantage of the battery gap, we will introduce an opening tool between the chassis and the housing to separate them.

Step 8 Side keys

To remove the buttons we will simply press them until they are unlocked.
