Tutorial: Step by step

Step 1 Back case

To begin, we must apply heat to the back cover in order to soften the adhesive that holds it, and with the help of one or more plastic spikes we will take off all the edges of the case.

Step 2 Shield with NFC antenna and wireless charging coil

We disconnect the wireless charging coil, the NFC antenna, and we will remove the five Phillips screws (PH # 00) that hold the shield, and we can unhook the shield and take off the wireless charging coil.

Step 3 We disconnect the battery

We disconnect the battery to work with greater safety.

Step 4 Speaker module

We extract the four Phillips screws (PH # 00) that hold the module, and with the help of a flat tool we will remove the speaker module.

Step 5 Interconnection flexes

We disconnect and extract the two interconnection flexes that are above the battery.

Step 6 Drums

We disconnect the flex from the screen, we introduce a few drops of alcohol along the edge of the battery to soften the adhesive that holds it, and with the help of a suction cup and a tool we will make a slight lever to lift the battery that we have to replace.
