Disassembly/Repair of the mobile device Infinix Zero X Pro with each step description and the required set of tools.

⚠️️ Before disassembling, do not forget to turn your phone off.

At the very beginning we need to remove the card tray.

For this we take a special tool, insert it into the hole and push out the card tray.

⚠️️ If the tray does not come out well, we can additionally use tweezers.

We need to heat the surface of the back cover to a temperature of about 70° C or 160° F. For this we use a heating mat you can use a hair dryer.

And after 5 to 7 minutes we can move on to disassembly.

To detach the back cover, we will use a plastic film, it can be a protective film from a new display or a film from the stationery store. We insert the film into the gap between the middle cover and the back cover and run it lengthwise cutting off the adhesive base.

Using a screwdriver Phillips 1.5 mm (PH #000), unscrew the six black screws.

Using a screwdriver Phillips 1.5 mm (PH #000), unscrew the one large silver screw.

If the screws are different:

ℹ️️ Be sure to note the location of the screws before disassembling. When assembling the device, screwing the screw in the wrong place may damage the device or its parts. To avoid damage, the removed screws and individual pieces (as gaskets or brackets) must be laid out in the appropriate order, or the screws and their holes in the phone must be marked with colored markers.

Using a screwdriver Phillips 1.5 mm (PH #000), unscrew the two silver screws.

Using a screwdriver Phillips 1.5 mm (PH #000), unscrew the one silver screw.

Please note that the screws are different from each other, in size, color and shape, so we recommend that you place them on a special surface in an easy-to-remember order, so that you do not confuse anything when reassembling. You can also take a picture of the screws before unscrewing them.

And we can detach the cover hiding the motherboard. Gently we pry up the edge in the right place and lift the cover.

It's strange, of course, but we have the cover detached with a large rear camera.

Disconnect the battery connector as soon as you can. Use a non-metallic or plastic tool to avoid any damage.

ℹ️️ The Infinix Zero X Pro model has a battery BL-44EX with a capacity of 4500 mAh (also known as a rechargeable battery).

And we move on to unscrewing the four black screws at the bottom. The screwdriver is the same 1.5 mm Phillips screwdriver.

⚠️️ The screws are also different from each other, so we need to remind you again that we recommend that you place the screws on a special surface in an easy to remember order for reassembly and they can also be photographed before unscrewing. And if the screws get stuck, we use tweezers.

Using a screwdriver Phillips 1.5 mm (PH #000), unscrew the two small silver screws.

Using a screwdriver Phillips 1.5 mm (PH #000), unscrew one screw, and we remove the small cover hiding the underscreen cable connector.

We disconnect the connector and bend the cable so it doesn't get in the way.

We need to disconnect the coaxial cable connector on the small antenna board and remove a part of the cable from the indentation in the cover.

And we can try to detach the cover with a loudspeaker. We find the right and convenient place to hook the cover and try to lift it off.

The cover is glued, on one side, we need to lift it carefully as not to damage anything.

Then we disconnect the connectors on the motherboard and sub-board and remove the inter-board cable.

ℹ️️ An arrow on the FFC cable (flexible flat cable) indicates its correct position.

We need to remove one screw securing the sub-board. The screwdriver is the same Phillips 1.5 mm, and this screw is also different from the previous ones.

After that we disconnect the coaxial cable connector.

To remove the sub-board, we need to first detach the vibration motor. Since the contact area of the vibration motor on this model comes from the top, unlike all the others.

We hook the vibration motor to the base and carefully unglue it.

And we can easily remove the sub-board.

On the sub-board we have a charging port, microphone and headset jack ports.

We can also peel off the copper heat dissipating coating on the front camera. We will remove the camera later.

After, we detach the two rear cameras and put them aside.

We disconnect the two connectors of the two coaxial cables and release the cables themselves from the clips fixing them on the motherboard.

And we unscrew the four screws securing the motherboard. The screwdriver is the same 1.5mm Phillips screwdriver.

⚠️️ The screws are also different from the previous ones, so it is really important not to mix them up when reassembling.

And we move on to disconnecting the display connector on the motherboard.

Finally, we can detach the motherboard. We also need to find the right place where we can pry it up and lift it.

As we can see the motherboard is held in the rear camera area. We need to carefully detach the rear camera from the display frame.

We turn over the printed circuit board. And we have to detach the front and rear cameras, but be extremely careful not to get thermal paste on the lenses when removing the cameras. We detach one front camera and one rear camera.
