Owners of Xiaomi Redmi 8 Pro smartphones often face the need to physically access the internal components of the device, which can be caused by a battery failure, a broken display or a desire to conduct a deep dust cleaning. Modern electronics require a special approach to dismantling, as manufacturers use water-resistant adhesive pads to seal the case.
The process of opening a monolithic case requires precision and the presence of a specialized tool. Wrong actions can damage the plumes or cracks on the glass back cover. In this article, we will look at each stage of dismantling in detail to minimize risks and perform the job efficiently.
Tools and workplace preparation required
Before you start dismantling a smartphone, you need to prepare the workplace, it should be well lit and free from unnecessary objects that can scratch the case or get lost, the ideal option would be an antistatic mat, but also a clean, flat surface of the table.
You'll need a toolkit to work with, which includes more than just standard screwdrivers. For the Redmi 8 Pro, it's critical to have a thin string or a special mediator to cut the glue under the back cover. Without this stage, further disassembly is impossible, since the cover is held solely on adhesive basis.
Here is a list of equipment that will ensure safe dismantling:
- 🔧 Precision screwdriver kit (cross-hatch) PH000, PH00)
- 🔥 Hair dryer or heat-heating station for heating glue
- 📱 Plastic mediators and screen suction cup
- 🧲 Magnetic screw-sorting mat
It is also highly recommended to use isopropyl alcohol or a special adhesive solvent, which will help soften the adhesive layer, making the process of detachment of the lid less traumatic to the glass, do not use aggressive chemistry that can damage the oleophobic coating or plastic elements.
Primary heating and separation of the back cover
The first step in the process of opening the Xiaomi Redmi 8 Pro is heating the perimeter of the device.The adhesive base holding the back panel at room temperature is very hard and can lead to chips when trying to fit the lid.
Turn on the dryer at the average temperature and evenly warm up the edges of the smartphone during 2-3 Do not keep the hot air flow in one spot for too long so as not to damage it. OLED-Periodically check the temperature with your finger - the glass should become noticeably warm, but not hot.
⚠️ Warning: Excessive heating can swell the battery or damage adhesives inside the display module.
Once warmed up, place the suction cup at the bottom of the back cover, closer to the edge. Carefully pull the suction cup upwards, creating a small gap between the glass and the frame. Insert a thin mediator or blade immediately into the resulting gap.
💡
Use isopropyl alcohol by dripping a couple drops into the gap, which will make it much easier to slide the tool and dissolve the glue.
Move the mediator along the perimeter, trying not to dive deeper than 3-4 mm. Inside the case, plumes can pass along the sides, which can easily be damaged by careless movement. Pay special attention to the areas around the camera module where the glue can be applied with a thicker layer.
Dismantling the protective panel and disconnecting the plumes
When you successfully remove the back cover, you'll see an interior space that's enclosed by a black plastic panel, and this part protects the motherboard and the battery from mechanical stress and dust, and it's secured by a lot of screws of different calibers.
You'll need a screwdriver with the smallest sting (usually a PH000) to unscrew all visible screws around the perimeter and in the center. Some screws may be hidden under stickers or decorative elements, so inspect the board carefully.
☑️ Procedure for removing screws
When you take the panel off, don't put it down. There are often antenna contacts on the inside of it that can get caught. Carefully put the plastic aside. You now need to turn off the power to the device before any further manipulation.
Find the battery connector on the motherboard. Using a plastic blade, gently snap the plume off. This is a critical step to prevent short circuits from accidentally touching other contacts with metal tools.
| Component | Type of attachment | Tool. | Risks. |
|---|---|---|---|
| Back cover. | Clay. | Fen, mediator | Slipped glass |
| Protective panel. | Screws (10-12 units) | Screwdriver PH000 | Carving failure |
| AKB slack | Clamp. | Plastic spatula | Contact break |
| Camera module | Screw + plume | Tweezers, screwdriver. | Lens contamination |
Battery extraction and glue handling
In the Redmi 8 Pro, the battery is located at the bottom of the body and is also fixed to double-sided tape. Trying to remove it without prior preparation can lead to deformation of the power cell, which is fire dangerous.
Use a hair dryer again to warm the bottom of the smartphone through an open space (if the back cover is removed) or through the screen (if the cover is still in place, but this method is less effective).
Use a plastic card or a special lever to gently lift the battery. Move slowly, starting from the bottom edge. If you feel strong resistance, add a solvent of glue.
⚠️ Warning: Do not pierce the battery body or bend it. Damage to the lithium polymer cell can cause ignition.
Once the old battery is removed, clear the seat of glue residues. The surface should be smooth and clean to securely fix the new cell. Set a new battery and plug the plume into the motherboard before clicking.
What to do if the battery is swelling?
Replacement of the display and touch screen
Replacing the screen with the Xiaomi Redmi 8 Pro is a more complex process that requires the motherboard to be completely dismantled. The display module in this model is glued to a metal frame, and often changes with it or requires re-adjustment.
To replace the screen, you need to unscrew all the remaining screws holding the board, and carefully remove it, turning off all the plumes (cameras, buttons, charging), then remove the frame with the broken screen.
The process of sticking glass onto a frame requires skill and special B-7000 glue or analogues. Apply a thin layer of glue around the perimeter of the new frame, install the module and press the load for several hours.
- 🧹 Carefully remove shards of old glass from the frame
- 🧴 Remove the surface before applying new glue
- ⏳ Let the glue dry at least. 2-4 pre-insertion
The assembly is done in reverse order. Make sure all the plumes are in their connectors to the end. The display module is the most fragile element, so press it evenly, without point pressure.
Assembly of the device and verification of functionality
The final step is to assemble the smartphone, put the plastic shield in place, and twist all the screws. Don't pull them over because the plastic might burst. Make sure that no wires are pinched.
Connect the battery and try to turn on the device. If the screen catches fire and reacts to touch, you can start gluing the back cover, apply a new layer of glue or use a ready-made adhesive base (B-7000, T-7000).
Press the back cover and lock the smartphone with rubber bands for 15-20 minutes for primary glue grip. After drying completely, wipe the case from the glue residue and check all the functions: speakers, vibrator, cameras and fingerprint sensors.

The quality sealing of the case is the key to the long service of the device after repair.
