Modern smartphones like the Xiaomi Redmi 6 Pro have become an integral part of everyday life, but their glass cases are often the victims of falls. Broken glass is not just an aesthetic defect, but a potential security threat, since sharp shards can damage a finger when swiping. Replacing this component requires accuracy, but it is quite possible for a user with minimal experience in electronic repair.
Before we start, it is important to assess the extent of the damage: if only the outer glass is affected or the display module is affected. If the image is not distorted, there are no black spots, and the touch screen responds to touches throughout the area, then replacing the outer glass is the most economical solution. However, if the matrix is damaged, it is easier and more reliable to replace the entire module in the assembly, which will also be considered in the context of preparation.
The recovery process requires specific tools and supplies. B-7000 or T-7000 glue is a prerequisite for sealing the case and securing the glass to the frame. Do not try to use superglue or other household adhesives, as they can damage the plastic frame or leave irremovable white marks on the matrix.
Tools and workplace preparation required
The success of the operation depends on 80% of the quality of preparation. You will need not only the new glass (or module), but also a set of specialized tools that will ensure safe disassembly. The absence of even one element can damage the plumes or the housing. The workplace must be well lit, and the surface must be clean and free of dust.
To work with Redmi 6 Pro, you will need the following tools:
- 🔧 Screwdriver Set (Cross Phillips #00 and Torx) T5) screw-breaker.
- 🧸 Plastic mediators or shoulder blades for opening the body without scratches.
- 🌡️ Thermolenta or hair dryer for softening the glue under the back cover.
- 🧲 Magnetic mat for sorting screws of different sizes.
- 🧴 Degreasing agent (isopropyl alcohol) for removal of glue residues.
If you don't have a professional heating pad, a normal hair dryer will do the job, but you need to be careful about heating, evenly spreading heat around the perimeter of the back cover. Overheating can damage the battery or cause the battery to bloat, which is absolutely unacceptable. The optimal heating temperature is about 80-90 degrees Celsius.
☑️ Checking readiness for repair
Rear cover removal and access to internals
Xiaomi Redmi 6 Pro has a design where the back cover is glued to a metal frame. To remove it, you first need to twist two screws from the bottom, located on the sides of the charging connector, and then the cover should be carefully tucked into the mediator at the bottom and lead along the side faces, gradually peeling it off.
It is important not to insert the tool too deeply, so as not to damage the fingerprint scanner plume, which is often attached to the inside of the cover. If the cover is removed tightly, reheat the edges with a hairdryer. Do not make excessive efforts, as the glass of the cover can burst from the bending.
⚠️ Warning: When removing the back cover, be extremely careful with the fingerprint scanner plume. Damage to the fingerprint scanner will cause the unlock function to fail, and replacing this component requires precise calibration.
Once the lid is removed, you can access the insides of the smartphone, and the first thing you need to do is turn off the battery to prevent short circuits from going forward, and the battery plume is underneath a metal plate that's mounted with multiple screws, and disconnecting the power is a critical safety step.
Removal of frame and dismantling of damaged module
Unlike many modern smartphones, the Redmi 6 Pro does not attach the display module (or glass) to a plastic frame, but directly to the metal medium body. However, for ease of replacement, you often have to work with the frame if you change the glass separately. If you change the module assembled with a frame, the process is simplified.
To remove the "filling" you need to twist all the screws around the perimeter of the metal frame. The number can vary, so carefully inspect all the holes. Once the screws are removed, the board and battery are carefully removed from the housing. The fee is maintained on plumes that require delicate handling.
The main stages of dismantling:
- 🔌 Disconnection of display and touchscreen plumes from the motherboard.
- 🔩 Turning screws of board mounting and dynamics.
- 🔋 Careful battery recovery (if it interferes with access).
- 📱 Heating the screen perimeter to separate the old glass or module.
If you change only glass, you'll need a separator or a thin string (nichrome thread) to cut old glass off the matrix, a process that requires professional skills and equipment, because the risk of damage to liquid crystals is very high, and at home, you'll often change the module assembly, which eliminates the need to cut the glass.
Nuances of work with adhesive base
Installation of new glass and assembly of the device
Before installing a new component, you must carefully degrease the metal frame, so there should be no dust, villi or greasy fingerprints on the surface, otherwise there will be air bubbles or garbage cans under the glass. Use a lilaless napkin moistened with alcohol.
Apply a thin layer of B-7000 glue or use a pre-made adhesive base (if it comes with a kit) around the frame perimeter. Avoid getting glue into the speakers, buttons or camera holes. Carefully install a new module or glass, combining it with the openings for the talk speaker and front camera.
Compatibility and Component Characteristics Table for Redmi 6 Pro:
| Component | Type of connection | Difficulty replacing | The necessary tool |
|---|---|---|---|
| Back cover. | Glue base | Low. | Fen, mediator |
| Display module | Shore + Clay | Medium | Screwdrivers, sucker. |
| Battery | Connector + Clay | Medium | Fen, plastic card |
| Maternity fee | Lots of plumes. | Tall. | Sets of screwdrivers, tweezers |
After installing the module, you must fix it with money bands or special clips on the 15-20 You can take the time until the glue is in place. Don't turn the phone on right away, let the designs sit down. Then plug the display and touchscreen plumes into the board, making sure the connectors are in the right position.
💡
When connecting the display plumes, never press the center of the connector. Only press the edges of the connector so as not to damage the fragile contacts below.
Typical errors and troubleshooting
Even when following instructions, beginners often make mistakes that can lead to additional costs. One of the most common problems is a broken touchscreen after assembly, which can be caused by poor plume contact or damage to tracks when disassembled sloppyly.
If the screen is working but the image has stripes or spots, it is likely that the module itself was damaged during dismantling or strongly pressed by the screw. In this case, only replacing the module will help. Also a common problem is peeling off new glass after a short time, which indicates a poor cleaning of the frame from the old glue.
Possible problems and solutions:
- 📉 Touchscreen dead zones: Check the plume pressing density, re-installation may be required.
- 🌫 Dust under glass: You can only eliminate it by re-disassembling and purging.
- 🔊 Wheezing speaker: Check if the speaker got glue into the mesh during assembly.
- 🔋 Phone not turning on: Make sure the battery is charged and the battery connector is snapped to the end.
⚠️ Warning: If the phone starts to discharge quickly or warm up in the camera area after assembly, immediately disassemble it.It is likely that the camera plume or other component will be compressed or damaged, causing a short circuit.
Another important detail is calibration. In some cases, after the touchscreen is replaced, software calibration may be required, although on MIUI this happens automatically in most cases. If the cursor runs away, try resetting to the factory settings, saving the data beforehand.
Final inspection and recommendations
The final step is to check all the functions of the device before you finally stick the back cover. Turn on the phone and check the sensor at all corners of the screen, the brightness, color reproduction and operation of the front camera. Make sure that the proximity sensor is working correctly, otherwise the phone will not turn off the screen during the conversation.
If all tests are successful, you can stick the back cover. Put the glue on the frame, set the lid and re-fix the device with rubber bands for 30-60 minutes. Full polymerization of the glue takes about 24 hours, so on the first day avoid getting moisture and heavy loads on the body.
Self-repairing is a great way to save money and gain valuable experience. However, if you feel insecure at any stage, it is better to contact a service center.
💡
High-quality cleaning of the frame from old glue and the use of the right adhesive is the guarantee that the new glass will last a long time and will not peel off in a month.
