Disassembly of a modern smartphone, especially the model with a monoblock case, always causes awe in the user who decided to repair himself. Xiaomi Redmi Note 6 Pro, despite its age, remains a popular device, and the need to replace the glass, battery or charging plume occurs often. However, the process of dismantling the rear panel here comes with certain risks, since it is glued around the perimeter and requires careful heating.
Before you start physical impact, it is important to understand that the tightness of the housing in this device is ensured by the adhesive layer, not screws or latches. Trying to simply tamper with the panel without prior preparation is guaranteed to lead to cracks in the glass or deformation of the frame. In this article, we will look in detail how to safely separate the back cover using available tools and observing safety precautions.
Your goal is to warm up the body evenly so that the adhesive composition is softened without overheating the display matrix and the internal components. Many people mistakenly believe that it is enough to pull hard, but in the case of the Redmi Note 6 Pro, this is a fatal error leading to glass breaking, and we will take every step from the preparation of the workplace to the final detachment of the plume.
Tools and workplace preparation required
You can't do a good job of disassembling without specialized, if inexpensive, tools. You need a heat source, which can be a professional thermal power plant, a normal hair dryer, or a hot water heater. For the Xiaomi Redmi Note 6 Pro, a hair dryer is the best option, because it allows you to pinpoint the gluing areas. You also need thin metal blades, mediators (plastic cards) and a suction cup.
Pay special attention to lighting and cleanliness of the surface. Small screws can easily get lost, and dust caught under the display or on the camera when assembled open will spoil the quality of photos or create bubbles on the screen. It is recommended to use a magnetic mat or container with sections to sort the fastener, as screws in this model can have different lengths and threads.
⚠️ Warning: Before starting any work, be sure to turn off your smartphone and remove the tray SIM-Working with the device on when the insulation of the tools is damaged can lead to a short circuit.
Keep your eyes and hands safe. When working with glue and heated glass, there is a risk of small fragments or splashes of molten adhesive. Safety glasses will be a useful addition to your arsenal, especially if you plan to use chemical solvents to remove old glue.
☑️ Disassembly tools
The process of heating the body and softening the glue
The most critical stage is heating.The glue used in the Redmi Note 6 Pro, becomes plastic at a temperature around 80-90 You need to heat evenly, driving a hair dryer around the perimeter of the back cover for a long time. 3-5 Do not keep the hot air flow in one spot for too long so as not to damage it. OLED-Matrix or not to melt internal plastic elements.
How do you know if the phone is going to warm up enough? Try to suction the edge of the glass carefully. If you feel resistance, but you see the glass play a little bit or move away, and then come back to its place, then the temperature is reached. If the lid feels "dead" glued, the heating procedure must be repeated. Cold glue cuts the glass like a razor, so insufficient heating is the main cause of broken rear windows.
There's a myth that you only need to heat the corners. In fact, the adhesive strip runs all over the perimeter, including the areas around the camera and the speakers. Pay special attention to the top where the camera modules are located, because there's a thicker layer of glue. Use a thermometer if your hair dryer doesn't have a temperature adjustment, so you don't go over the 100-degree threshold.
💡
Use an infrared thermometer to monitor surface temperature, and if the skin of the hand barely touches the body (about 45-50 degrees), the glue inside is still cold, and the body should be hot, but not burning to the point of pain.
After the initial heating, a thin metal blade or blade can be gently inserted into the junction between the frame and the glass, preferably in the area of the charging socket or upper speaker where there are no plumes. The movement should be sliding, parallel to the plane of the body, and not perpendicular to it, so as not to push the glass inside.
Technique of detachment of the cover and work with shoulder blades
Once you've inserted the first tool, don't try to crack the gap right away. Your job is to cut the adhesive layer around the perimeter. Put a second mediator next to the first one and slowly drive them along the long side of the body. You'll hear the characteristic sound of the adhesive being cut, which is a normal workflow. The main thing is not to make any sudden jerks.
In the area of the main camera module and fingerprint scanner (if it is on the lid, although in the Redmi Note 6 Pro it is on the back), you need to act with increased caution. Here the glass can be thinner, and under it there are important plumes. Use plastic cards instead of metal in these areas to minimize the risk of damage to flexible plumes or scratches on the internal components.
If you feel that the lid is not moving away, do not use force. Go back to the heating phase. Often users make the mistake of picking the center of the lid, which leads to instantaneous cracking of the glass. Move strictly from the edges to the center, gradually clearing the perimeter. When all sides are passed, the lid should be removed with a slight movement of the hand or suction cup.
Even after unpicking, it remains fragile, and put it in a safe place with a soft cloth so that it does not accidentally drop or break against the hard surface of the table during further work with the insides.
Disconnecting plumes and access to internal components
Once you remove the back cover, you'll have access to the battery and the bottom board, but the motherboard is still covered by a plastic safety pad, and it's mounted on a lot of screws of different calibers, and you'll need to carefully unscrew all the visible screws, including those hidden under stickers or deep in the holes.
In the Xiaomi Redmi Note 6 Pro, the plume connecting the main board and the bottom board (where the charging connector is located) runs along the battery. Be extremely careful when lifting the protective plate: do not damage this plume, as replacing it requires a complete disassembly of the phone.
| Component | Location. | Risk of damage | Tool. |
|---|---|---|---|
| Display plume | Above, under a metal screen. | High (with careless screen removal) | Plastic spatula |
| Battery | Central part of the hull | Medium (puncture risk) | Suction, plastic. |
| Main camera. | Upper left corner | Medium (lens scratches) | Tweezers |
| Charging plume | Along the battery. | High (contact gap) | Plastic card |
To disconnect the connectors from the motherboard, use a plastic blade or nail. Metal tools are undesirable here, because you can accidentally close contacts on the board, which, if there is a residual charge in the battery (if it is not turned off first), can cause the power controller to fail. First disconnect the battery, then all the other plumes.
⚠️ Warning: Never pull the plume to disconnect the connector, and you need to press the connector (black plastic pad), not the flexible part of the cable, otherwise you will break the conductive tracks.
Frequent Dismantling Mistakes and How to Avoid Them
One of the most common mistakes is ignoring screws under stickers. In the design of the Redmi Note 6 Pro, some screws can be hidden under decorative elements or protective seals. Trying to remove the plastic lining without twisting all the screws will lead to breakage of plastic latches, which will then rattle or prevent the body from closing tightly.
Another mistake is to use aggressive chemistry to remove the old glue immediately after opening, so if you drip the solvent inside the case, the fluid can leak under the display or onto the motherboard, causing corrosion or detachment of the polarizing film of the screen, first make sure that all components are securely secured or protected.
Keep in mind the statics: Dry air indoors and rubbing tools can create a static charge that is dangerous for microelectronics, and it is advisable to work on an antistatic mat or at least periodically touch a grounded metal object to remove the charge from the body before touching the board.
What if the screw licked?
Also, users often forget about the fingerprint scanner plume if it is integrated into the back cover (in this model, the scanner is at the back, but the plume can go to the board). Sharply pulling the cover without checking connections is a sure way to break this thin wiring, after which the finger unlock function will stop working.
Building and final recommendations
The assembly process is reversed, but it has its own nuances: before installing a new or old back cover, you need to completely remove the residue of the old glue from the frame, this can be done neatly by cutting with a scalpel or using a special solvent without touching the painted parts of the frame, the surface should be perfectly smooth and fat-free.
To fix the lid, use a special electronics adhesive (e.g., B-7000 or T-7000) and apply it with a thin continuous line on the frame, avoiding camera and speaker lenses. After gluing the lid, it is advisable to lock the smartphone with rubber bands for 1-2 hours to polymerize the adhesive.
Checking your performance is a must before you get your screws rolled, turn on your phone, check your touchscreen, your cameras, your microphone, your speaker, your charging, if everything works, you can spin your screws and enjoy the results, and if something doesn't work, you better find the reason right away than take the phone apart.
💡
High-quality cleaning of the frame from old glue and the use of the correct adhesive is the guarantee that the phone will not creak, dust inside and retain moisture protection (at a minimum level).
Remember, self-disassembly takes away your warranty if it was still in effect. However, for the Redmi Note 6 Pro, which is already out of warranty terms for most users, it's a great way to extend the life of the device and save on the services of a service center.
