Tutorial: Step by step

Step 1 Back case

First of all we must apply heat to the casing to soften the adhesive that holds it, and with the help of a fine enough tool we will open a small hole through which we will introduce one or more plastic spikes, with which we will take off all the edges of the housing.

Step 2 NFC antenna and wireless charging

We disconnect and detach the NFC antenna module and wireless charging.

Step 3 We disconnect battery

We remove the five Phillips screws (PH # 00) that hold the shield, and once removed we can disconnect the battery to work with greater security.

Step 4 Speaker

We extract the five screws that hold the speaker, and with the help of a flat tool we unhook it.

Step 5 Auxiliary board

We disconnect the two flex bridges that join the auxiliary plate and the motherboard, remove the three Phillips screws (PH # 00) that hold the damaged plate, and using a flat tool we will lift it.
