Xiaomi Redmi Note 8 Pro is deservedly considered one of the most popular devices of its time, but even reliable equipment requires intervention over time. Broken glass, worn-out battery or problems with the charging connector are typical scenarios when the owner has to think about self-repair. However, the internal design of modern gadgets requires not only accuracy, but also a clear understanding of the sequence of actions so as not to damage fragile components.
Before you start disassembling the case, you need to realize that opening the device automatically deprives you of an official warranty if it was still in effect. The dismantling process in the Redmi Note 8 Pro model has its own features related to the design of the rear cover and the location of the plumes. In this article, we will take a detailed look at each step, from tool preparation to the final assembly, to minimize the risks.
The Redmi Note 8 Pro features a glass back panel, making it more risky than plastic counterparts. Incorrect heating or sloppy movement can lead to cracks that make further operation impossible without replacing the lid itself. So be patient and follow the instructions carefully.
Preparation of the workplace and necessary tools
Good workplace preparation is the foundation of a successful renovation. You'll need a spacious table with good lighting, where nothing will distract you. The chaos on the table often leads to the loss of small screws or accidental damage to components, so remove the extra items.
To work with the Xiaomi Redmi Note 8 Pro, you will need a specific set of tools that are not always in the home medicine cabinet. Using inappropriate items such as kitchen knives or thick needles is strongly discouraged, as they can damage internal cables.
- 🔧 Precision screwdrivers (cross-hatched) PH00, PH000 flat).
- 🔥 Hair dryer or heating pad for heating the adhesive layer.
- 💳 Plastic mediators or blade for opening.
- 🧲 Magnetic screw-sorting mat.
- 🧤 Antistatic gloves and tweezers.
Pay special attention to the Torx screwdriver, as the design of the smartphone uses screws with an asterisk. Conventional cross tools can lick the hats, which will turn a simple repair into a complex puzzle for drilling fasteners.
⚠️ Warning: Before starting any work, be sure to turn off your smartphone and make sure it is completely cooled if it has worked before.Working with a heated phone can cause burns or battery bloating if an accidental puncture occurs.
Removal of the back glass cover
The first and most important step is to remove the back panel. In the Redmi Note 8 Pro, it is attached to a two-part glue that requires pre-softening, and without heating, trying to remove the lid will lead to its destruction.
Use a hair dryer to warm up the perimeter of the device evenly. Keep the heat source 3-5 cm from the surface and move it constantly to avoid overheating one point, which can damage the display or internal components.
After the case is warm (about 60-80 degrees), carefully insert a plastic card or mediator into the junction between the frame and the glass. Move the tool around the perimeter, gradually cutting the adhesive layer.
💡
Use a suction cup to slightly lift the edge of the lid after heating, creating a gap for the insertion of the mediator, which will greatly simplify the beginning of the process.
It is important not to insert the tool too deeply so as not to touch the fingerprint scanner plume or other sensitive elements located at the edges. The fingerprint scanner in this model is integrated into the back panel, and its plume requires special care.
Dismantling internal components and protection against statics
After successfully removing the back cover, you have access to the main board and battery, but you can't rush to remove the modules, you need to turn off the power first.
First, unplug the plume from the fingerprint scanner, which can be glued to the inside of the lid, then move to the main board, where you need to turn off the display and battery connectors.
| Component | Type of connection | Location. | Features |
|---|---|---|---|
| Battery | Latched plume | The bottom of the fee | Requires careful deflection |
| Display. | Wide plume | Centre de la carte | Closed with a metal plate |
| Finger scanner | Thin plume | Cover/Paid | Very fragile, easy to break |
| Main camera. | schleife | Upper part | Locked by a screw. |
To access some of the plugs, you have to twist screws that lock metal shields, and remember the location of each screw, as they can have different lengths and threads.
⚠️ Warning: Never try to disconnect the plume by pulling the wire itself. Always use a plastic shoulder blade or nail to fit the connector vertically upwards.
☑️ Check before disconnecting the plumes
Replacement of the battery and work with the glue layer
In the Xiaomi Redmi Note 8 Pro, the battery takes up a significant part of the internal volume and is attached to a powerful two-way tape. Battery replacement is one of the most common reasons for disassembly.
To remove the old power, it needs to be heated to soften the glue. Use a dryer at low temperature, directing heat flow to the back of the device (if the cover is not yet removed) or gently warming the end.
To extract, use special pull strips or a thin line that must be carefully stretched under the battery. The movements must be smooth, without jerks, so as not to deform the battery.
Installing a new battery requires careful cleaning of the seat from the residue of old glue. Use isopropyl alcohol and a plastic card to remove the sticky layer.
How to safely remove the glue residue?
The new battery should be fixed with a special glue B-7000 or double-sided tape designed for electronics, which will prevent the battery from moving when falling.
Dismantling the display and camera module
If your goal is to replace the screen, then after turning off the plumes and removing the protective plates, you can start dismantling. In the Redmi Note 8 Pro, the display module is often changed in the assembly with the frame, which makes it easier to do.
When you're working with cameras, remember that optics are very sensitive to dust. Any speck of dust on the lens can ruin the quality of your photos. Try not to touch the glass elements with your fingers.
- 📸 Main camera: removed after the screw is unscrewed.
- 🔍 Macro camera and wide-angle: require turning off their plumes.
- 🤳 Front camera: located at the top, accessed through the notch in the screen (if it is not assembled with a frame).
When installing a new display, be sure to check its performance before final assembly and gluing. Connect the plumes, turn on the phone and check the touchscreen, colors and sensors.
⚠️ Warning: Display plume is one of the most vulnerable elements, and if it is damaged, the screen may stop working or display artifacts of the image.
💡
Always check the health of all the replaced components before final assembly and application of glue.
Device assembly and function testing
The final step is to build the Redmi Note 8 Pro in reverse order. Make sure all plumes are snapped to the characteristic clicks and the screws are swirled with the correct force.
Before sticking the back cover, wipe it and the frame with degreasing alcohol. Apply a new layer of glue around the perimeter, avoiding getting into the cameras and sensors.
After assembly, take your time to turn on the device.Let the glue grab for 15-20 minutes, pressing the edges with rubber harnesses or putting something heavy (but not on the screen).
Turn on your smartphone and do a full test: check the sound, vibration, operation of all cameras, Wi-Fi, Bluetooth and, of course, the fingerprint scanner.
