Smartphones series Redmi from Xiaomi deservedly popular due to the excellent ratio of price and quality, but over time, even the most reliable device may require intervention. Xiaomi Redmi 6 Pro, with a metal body and glass back cover, is a difficult object for dismantling, requiring accuracy and specific tools. Owners often face the need to replace the battery, broken screen or failed charging plume, and knowledge of the nuances of the design allows you to carry out the procedure as safely as possible.
The process of opening the body of this device is very different from the disassembly of more modern models with fully plastic bezels or glass sandwiches. Here the engineers took a combined approach: an aluminum frame serves as the basis to which the glass is attached to the rear and the display module in the front. The main difficulty is that access to the internal components is only opened after removing the rear panel, which is glued around the perimeter, and the body is held by many screws of different calibers, the entanglement of which can lead to damage the board.
Before you start taking action, you need to be clear about the risks: self-disassembly deprives you of an official guarantee if it is still valid, and careless movement of the scalpel can damage the plumes or the motherboard itself. However, if you are willing to act methodically and use the right tools, restoring the functionality of the gadget with your own hands will save a significant amount of money. In this article, we will discuss in detail each step, from warming the glue to the final assembly, to minimize the likelihood of errors.
Tools and workplace preparation required
A high-quality dismantling of the Redmi 6 Pro is impossible without a specialized set of tools, since the use of improvised tools like knives or needles often leads to scratches on the body or, worse, to a short circuit. You will need a set of precision screwdrivers, necessarily including cross bits PH00 and PH000, as well as a flat screwdriver for neatly cracking the plumes. Equally important is the suction cup to lift the back cover and thin plastic mediators that will not damage the adhesive layer of the adhesive and the adhesive components.
Special attention should be paid to the heating source, because the adhesive base that fixes the rear window softens under the influence of temperature and allows you to remove the panel without chipping. You can use a professional thermophen with temperature control, setting a value of about 80-90 degrees, or, in extreme cases, a conventional household heating pad, although the latter option will take longer. It is critical not to overheat the device above 100 degrees, as this can lead to bloating of the battery or deformation of plastic elements inside the case.
⚠️ Warning: Before starting any work, be sure to completely turn off the smartphone. Attempting to disassemble the on device with the connected battery is guaranteed to short circuit and the electronics fail.
The organization of the workspace also plays a key role in the success of the operation.It is recommended to use a magnetic mat or a set of containers for sorting screws, since the Xiaomi Redmi 6 Pro uses fasteners of different lengths that are easy to confuse.Install a good lamp so that light falls directly on the work area, eliminating shadows, and prepare tweezers with curved ends to capture small parts in the depth of the case.
Dismantling of the rear glass panel
The first and most important step is to remove the back cover, which in this model is made of glass and planted on glue. Put the smartphone off the screen down on the soft surface so as not to scratch the display, and evenly warm the perimeter of the rear panel for 2-3 minutes. Do not hold the hair dryer still at one point, constantly drive them around the circuit so that the heat is distributed evenly and the glass does not burst from thermal shock.
After warming up, carefully place the suction cup at the bottom of the back cover, closer to the Redmi logo, and pull up, creating a small gap between the glass and the frame. Insert a plastic mediator or a thin line into the resulting gap and begin to carefully lead around the perimeter, cutting the softened adhesive layer. The movements should be smooth, without sharp jerks, since plumes pass under the glass, which, if carelessly jerked, can easily be damaged.
Be very careful in the upper part of the case, where the camera and the main plumes are located. Do not try to open the lid completely like a book until you make sure that the glue has detached around the perimeter. It is best to snap one long side, then a short one, and only then gently lift the glass, gaining access to the insides of the device.
Disconnecting the battery and removing protective screens
Once the back panel is removed, you will see the inside of the smartphone, covered with black security stickers and metal screens. The first thing you need to do before you remove any screws is to find the battery connector and carefully disconnect its plume from the motherboard, using a plastic blade or nail, putting the connector upwards, which will turn the device off and protect you from accidental circuits when you go on.
Next, you have to dismantle the metal plate that covers the motherboard and the plume connectors, and it's fixed by multiple screws of different sizes, so it's important to remember or record their location, and once you remove the plate, you'll have access to the main plumes of the display and touchscreen, which you also need to turn off by putting their connectors up.
| Type of screw | Location. | Number of | Appointment |
|---|---|---|---|
| Long. | Fee angles | 2 pcs. | Fixing the basic framework |
| Medium. | Centre de la carte | 2 pcs. | Metal screen attachment |
| Short. | Near the camera | 1 pc. | Fixing the plume |
| microvitamin | Dynamician | 2 pcs. | Fixing of the multimedia module |
Once all plumes are turned off, you can retrieve the motherboard, but this will require removing the upper plastic antenna frame if it interferes with access. In the Redmi 6 Pro, the design allows you to access most nodes without fully removing the board, but to replace the charging connector or speaker you will have to work in the depths of the case.
Replacement of the battery and work with adhesive base
The battery in Xiaomi Redmi 6 Pro is located at the bottom of the case and is also fixed to double-sided tape, which makes it difficult to remove. Under no circumstances do not try to tamper with the battery with metal objects, as a puncture of the lithium-ion cell shell can cause fire or a chemical reaction.
Use plastic cards or special blades to carefully separate the battery from the frame. Move the tool parallel to the plane of the battery, gradually moving deeper. If the battery is difficult to remove, you can use a small drop of isopropyl alcohol injected under the edge of the battery, which will weaken the adhesion of the glue.
☑️ Check before installing a new battery
When installing a new power supply, make sure that the contact area on the plume is clean, and press the connector tightly until the characteristic click. Use a new layer of glue or special adhesive strips, which often come complete with quality batteries. Old Scotch is better removed completely so that the new one is flat and reliable, to fix.
Removal of the display module and touch screen
Replacing a broken display or touchscreen is the most common reason for disassembling smartphones. In the Redmi 6 Pro, the display module is glued into a frame, and its replacement requires either heating around the perimeter of the screen or using a thin string (molybdenum thread).
Once you warm up the perimeter, you insert a thin mediator, and you start the process of breaking the glass off the frame, and you move slowly, passing through the entire circuit several times, gradually increasing the depth of penetration of the tool, and it's important not to push the center of the screen, because this can lead to cracks in the already damaged glass or damage to the matrix under it.
⚠️ Warning: When working with the display, avoid dust between the new glass and the frame, as it will be almost impossible to remove the dust after gluing without redisassembling.
If you change only the touchscreen and the matrix is intact, the process is complicated by the need to separate the layers with a separator and remove the old glue (OCA) from the matrix, which requires high skill and special equipment, so at home, you often change the module assembled with a frame, which is much easier and more reliable.
Access to charging connector and dynamics
Replacing the USB Type-C charging connector or speaker in the Xiaomi Redmi 6 Pro doesn’t always require full motherboard removal, but access to these components is limited.The charging connector is located on a separate board at the bottom of the case and connected to the motherboard through a wide plume that runs under or along the battery.
To get to the bottom board, you need to remove the plastic speaker plug, which is usually held on screws and glue. Be careful: the speaker in this model also has an O-gaming gum, which you need to carefully install in a new place so that the volume does not go down or leaks.
What if the phone does not charge after the plug is replaced?
When installing a new connector, make sure that the screws of the clamping bar are twisted evenly, otherwise the contact may be unstable. After assembly, it is recommended to check the charging, headphone connection and microphone before final sealing of the case.
Assembly of the device and verification of functionality
The Redmi 6 Pro is built in reverse order, but requires a special attention to the sequence of actions. First, all the internal components are installed, the plumes are connected and the device is checked in an open form, only after making sure that the touchscreen responds, the sound works, and the camera takes a photo, you can start the final fixation.
Apply a new layer of glue around the perimeter of the back cover or use a pre-made adhesive frame (B-7000 or analog). Carefully align the cover with the body starting at the top and press tightly around the perimeter. For better adhesion, you can use rubber harnesses or heavy objects, leaving the smartphone to dry for several hours.
💡
Use rubber harnesses or stationery gums to tightly press the back cover against the body during drying of the glue. This will ensure uniform fit and no gaps.
The final test involves testing all the proximity, light, vibrator and communication module sensors, and if all the functions are working correctly and the screen has no lights and dead zones, the disassembly can be considered a success.
💡
Quality assembly depends on the purity of the internal surfaces and the correct timing of the screw tightening - do not drag the mounts, so as not to tear the thread in the aluminum frame.
