Xiaomi Redmi Note 8 Pro has become a real bestseller thanks to its powerful processor and excellent camera, but the glass rear panel, despite the premium, remains a vulnerable element of the design. Falls, bumps or simply careless handling often lead to cracks that not only spoil the appearance, but can cause moisture to enter the body. Owners often wonder whether you can replace the broken glass yourself, and the answer to it is yes, but the procedure requires accuracy and understanding the specifics of the device.
The dismantling process is different from older models with plastic covers, as it uses strong glue and double-sided perimeter tape. Removing the back cover is the first and riskiest step of any repair, whether it's replacing the battery, display or cleaning the connectors. Wrong actions at the start can damage the internal plumes or the newest part you plan to install, so it's crucial to prepare the workplace and the necessary tools in advance.
Before you start heating and using tools, you need to make sure that you have specialized equipment that minimizes the risks of damage. To work with the Redmi Note 8 Pro, you will need not only a standard set of screwdrivers, but also tools to safely heat the adhesive layer.
- ๐ฅ Hair dryer or heating platform for uniform heating of glass (temperature about 80-90 degree).
- ๐ณ Plastic cards, mediators or thin metal blades for peeling off.
- ๐งช Fluid B-7000 or a special glue for phones for final fixation.
- ๐ง Torx (star) and Phillips (cross) screwdrivers for screw dismantling.
Special attention should be paid to the suction cup, which will help create a primary gap between the case and the glass. If you do not have a professional heater, a household hair dryer will also cope with the task, but you need to warm evenly, constantly moving the nozzle around the perimeter to avoid local overheating of the matrix or battery.
โ ๏ธ Warning: Before starting any work, be sure to turn off the device! Attempting to remove the lid on the phone on can lead to a short circuit if the tool touches the contacts of the plumes or boards.
Workplace preparation and security measures
Space management is critical to the success of the operation. You'll need a clean, well-lit table, preferably with antistatic coating or just no pile. Small screws have the ability to fly around the room and get lost in the carpet, so prepare a magnetic mat or a few containers to sort the fastener.
Battery safety is priority number one. The Lithium Polymer batteries installed in the Redmi Note 8 Pro are sensitive to puncture and heat. If you smell fumes or see a bloated battery during the heating process, stop working immediately. It is also worth removing the SIM card and memory card before disassembling so that the slots do not damage when the case is deformed.
โ๏ธ Ready for repair
Keep in mind your personal safety: eye protection glasses can save you from small glass shards if the lid cracks when heated. Work in a ventilated environment, as the adhesive vapor and heating of plastic can produce a specific smell.
The process of heating and creating a primary gap
The glue used by Xiaomi to seal the Redmi Note 8 Pro softens at about 80 degrees Celsius.Warm the device's perimeter evenly for 3-5 minutes.Do not hold the hair dryer at one point for too long to not damage the oleophobic coating (if it survives) or overheat the display on the back side.
After heating, try to gently pull the suction cup upwards. If the lid doesn't lend itself, don't use excessive force, you'd better warm up for another minute. Your goal is to create a microscopic gap of 1-2 millimeters where you can insert a thin plastic card or blade.
โ ๏ธ Warning: Do not insert metal tools deep into the gap immediately. Inside, right under the glass, there are plumes of the display and side buttons that are very easy to cut or damage.
Once the suction cup is stuck and you feel a little movement of the glass, insert a plastic mediator into the gap that formed. Move slowly, sliding the tool along the edge to dissect the glue layer. If you hear the crunch of the glue, that's a good sign, then the process is going right.
What to do if the lid is not removed?
Perimeter cracking technique
As you move around the perimeter, use a second mediator or map to fix the areas that have been peeled off. Don't try to remove the lid from one side at a time. Move around the circle: bottom, sides, top. Pay special attention to the corners where the glue layer is usually thicker.
Be very careful in the area of the camera and scanner.
- ๐ช Use a thin blade only for the initial entrance, then work with plastic.
- ๐ Change the angle of the instrument if you feel strong resistance.
- ๐ก๏ธ If the glue is frozen and the tool stopped walking, warm up the problem zone again with a hairdryer.
When you pass the entire perimeter, the lid should move away fairly freely. Don't pull it sharply, check if there are any clutch points left in the center or near the main camera module.
Disabling the plumes and removing the cover
Even if the lid has physically detached from the frame, it's still connected to the motherboard by a thin plume of the fingerprint scanner. A sharp jerk is guaranteed to cause this plume to break and the scanner will stop working. Carefully lift the glass and find the connection.
The plume is usually fixed in a connector on a board or under a protective metal plate. Use a plastic blade or tweezers with dielectric tips to gently snap the connector, after which the back cover is considered completely free.
๐ก
When you turn off the plumes, always pull the connector itself, not the wires, and pulling the wires leads to a cliff at the base, which is extremely difficult to seal at home.
Now you can remove the glass completely and put it in a safe place, and it is recommended to immediately clean the frame of the case of residues of old glue using tweezers and, if necessary, a little isopropyl alcohol, but not pouring the inside of the phone.
Table of compatibility and differences of modifications
When ordering a new lid, it is important to consider the region of the device, and although visually they may be similar, there are nuances in the location of the holes under the logos or certification marks.
| Parameter | Global version | Chinese version | Indian version |
|---|---|---|---|
| Mi logo | Silver/Golden | Black/Absent | Silvery |
| Redmi's inscription | Got it (large) | Got it (large) | Got it (large) |
| Color options | Black, White, Blue, Green | Black, White, Orange. | Black, white, green. |
| The antenna holes | Standard. | Standard. | Standard. |
As you can see from the table, the main differences are in the markings. Make sure the part you order matches your color scheme and logo layout if you care about the original look. Technically, the covers are interchangeable if the device model matches.
Installation of a new cover and sealing
Before installing a new glass, you need to carefully clean the seat on the frame, the old glue is removed mechanically, and degreasing is carried out with alcohol or a special cleaner, and a new adhesive composition is applied to the clean surface.
The best choice is the B-7000 glue, which remains elastic after drying and allows you to reopen the phone if necessary.Apply the glue with a thin continuous line around the perimeter, avoiding getting into the camera lenses and on the speaker.
๐ก
The main secret of a high-quality installation is the uniform distribution of glue and the use of rubber bands or cargo to fix the lid for the drying time (at least 2-3 hours).
After applying the glue, carefully align the lid with the body, starting at the top where the plume is located. Connect the scanner plume, make sure it is in the groove before the click, and then press the glass around the edges. Excess glue that has protruded out, you need to immediately remove with a dry wipe until they freeze.
โ ๏ธ Warning: Don't turn on the phone right after assembly! 30-60 minutes, otherwise the pressure when heating the battery can squeeze the still not frozen glue inside the case or disrupt the geometry of the fitting.
