Replace the broken screen on Xiaomi Redmi Note 8 Pro with your own hands

Xiaomi Redmi Note 8 Pro was rightly considered the king of the mid-range at one time, offering a great AMOLED screen, powerful camera and performance. However, the display glass remains the most vulnerable part of the design, and an accidental fall often leads to cracks or a complete failure of the matrix. Screen replacement is one of the most difficult procedures in modern electronics repair, requiring accuracy, special tools and understanding of the internal device.

In this article, we will discuss in detail the process of replacing the display module with the Redmi Note 8 Pro, consider the necessary tools and steps. It is important to understand that self-repair always carries risks, but if you follow the technology, you can return the device to life and save a significant amount of money on the services of the service center.

Before you start dismantling, you need to make sure that there is a quality spare display, the market is saturated with copies, and the choice of original or as close as possible in quality. OEM-The copy will be a crucial factor for the future of image quality and touchscreen performance. Below are detailed instructions that will help you go this way from preparation to first switching on.

โš ๏ธ Warning: Before starting any work, be sure to turn off the smartphone. Attempting to replace the screen on the device on can lead to short circuit and failure of the motherboard.

Tools and workplace preparation required

To work with the Xiaomi Redmi Note 8 Pro, you will need not only a standard set of screwdrivers, but also specific devices for working with adhesive joints. The preparation of the place must be done carefully: provide good lighting and use an antistatic mat or a clean surface covered with fabric, so that small screws are not lost.

The main tool to separate the glass from the body will be a heating element. Because the display is glued around the perimeter, it must be heated to a temperature of about 80-90 degrees Celsius. Using an open fire or too powerful heat sources, such as a building dryer at maximum power from a close distance, can damage the plastic elements of the frame or overheat the battery.

  • ๐Ÿ”ง Precision screwdrivers (cross-hatched) PH000, PH00) and slings for screws of different calibers.
  • ๐Ÿ”ฅ A heating pad (separator) or a building hair dryer with a thermostat for heating the glue.
  • ๐Ÿ’ณ Plastic cards, mediators or special blades for opening the case without damage.
  • ๐Ÿงฒ Magnetic mat or organizer for sorting screws by disassembly stages.
  • ๐Ÿงด B-7000 glue or double-sided tape to fix the new display.

Special attention should be paid to the suction cup, which will help create an initial gap between the glass and the frame. If you do not have a professional separator, you can use a regular home hair dryer, but the process will take longer. It is important not to overheat one point for too long, evenly spreading the heat around the perimeter of the device.

Rear cover removal and removal of components

The process of disassembling the Redmi Note 8 Pro begins with the removal of the rear glass panel. Unlike many modern smartphones, there are no screws hidden under the plugs, but there is a risk of damaging the glass if you do not open it neatly. Heat the back cover around the perimeter for 2-3 minutes, then gently lift the edge with a sucker and insert a plastic card.

Swipe a map or blade along all the faces, gradually cutting through the adhesive layer. Do not try to open the lid with a jerk, as inside it may be glued to plumes or elements, although in this model the main electronics are protected by a metal frame. Once the lid is removed, you will see the NFC logo, which is often located on the inside of the glass, and access to the main board.

The next step is to remove the metal protective frame that covers the battery and connectors of the plumes, and it is fixed by many screws of different sizes, so it is extremely important to remember or record their location. Once all the screws are unscrewed, the frame is easily removed, opening access to the battery and the loops of the display.

The first step inside the case is to turn off the battery, find the battery connector on the motherboard and gently disconnect it with a plastic blade, only then you can safely turn off the display and touchscreen plumes, avoiding damage to the golden contacts.

Removal of the old display module

The most critical thing is to separate the broken display from the plastic bezels. The screen in the Xiaomi Redmi Note 8 Pro is held on a powerful adhesive layer. Heat the front of the device to soften the glue, and start gently tweaking the edges of the display with a thin string or a special knife.

Move slowly, controlling the depth of penetration of the tool so as not to damage the plastic frame itself or the parts under the display.If the screen cracks badly, the glass may crumble, so it is recommended to pre-seal the surface with a wide transparent tape to hold the fragments together.

Once the module is separated from the frame, it must be carefully removed. Often the plume may be slightly glued to the frame, so use a plastic card to snap. Make sure that there are no pieces of old glue or glass left on the frame, as this will prevent the new screen from being evenly installed.

โš ๏ธ Warning: When working with a broken screen, use safety glasses. Small pieces of glass can fly into the eyes, leading to serious injuries.

Cleaning the frame and installing a new screen

Installing a new display requires a perfectly clean frame surface. Carefully remove the residue of old glue using alcohol or a special solvent. Any speck of dust or irregularity can cause the new screen to fit tightly, affecting moisture protection (although it is already weak after repair) and appearance.

Apply a thin layer of B-7000 glue around the perimeter of the frame, or use a pre-painted double-sided tape if it comes with the display.Do not apply the glue too close to the inner edge so that it does not squeeze out on the matrix itself when pressed.

Carefully place the new display module in the frame, combining all the faces. Make sure that the plume is displayed in the right direction and not bent. Press the screen around the perimeter and fix it with rubber rings or loads for the time of drying the glue (usually 15-30 minutes).

While the glue is drying, you can plug the display plume into the motherboard for pre-screening. Don't screw the board, just plug the connectors in and press the switch button. If the image appears and the touchscreen responds to touch, you can continue building.

What to do if the new screen is not working?
If the screen doesn't light up after installation, check the connector's density. Sometimes you need to press a little harder to the characteristic click. Also check if there's any debris between the contacts. If the problem isn't solved, maybe the new module itself is faulty or the plume is damaged during installation.

Smartphone assembly and calibration

Once successfully tested, assemble the device in reverse order. Set the metal safety frame, twisting all the screws into their places. Pay special attention to the screws around the connectors, as their length may vary, and twisting a long screw into a short hole can damage the board.

Connect the battery and put the back cover in place, preheat its edges to activate the glue. Press the edges of the case hard to ensure reliable fixation. Once the phone is turned on, you may need to calibrate the touchscreen if you notice inaccuracies in operation.

To calibrate in the Xiaomi engineering menu, type ##64663## in the dialer. Select "Touchpanel" and follow the instructions on the screen, drawing lines around the perimeter, which will help the system redefinite the boundaries of the workspace.

The quality of the gluing frame and display directly affects the durability of repairs - do not save on glue and drying time.

Possible problems and solutions

Even with careful operation, there can be unforeseen difficulties, and users often find that after assembly, the proximity sensor stops working or a dead zone appears in the corner of the screen, in most cases, this is solved by reconnecting the plumes or resetting the settings.

If the touchscreen "gluts" or spontaneously presses, check whether the plume is transmitted by a pinch bar. It is also worth eliminating the influence of a poor-quality charger, which can interfere with the capacitive layer of the screen.

  • ๐Ÿ”‹ Fast discharge โ€“ possible if the power controller was damaged during disassembly or the sensor is turned off.
  • ๐ŸŽจ Unnatural colors โ€“ a sign of an unoriginal matrix or incorrect color reproduction settings in the menu.
  • ๐Ÿ“ถ Weak signal โ€“ if the antenna contact was shifted or damaged when the frame was removed.

In rare cases, a screen change may require a flashing device, especially if memory or display controller has been affected. However, for the Redmi Note 8 Pro, this is more the exception than the rule.

Why does the phone run out quickly after changing the screen?
This can be due to several factors: First, a new display (especially a non-original one) can consume more power; second, the battery plume or connector may have been damaged during disassembly; and third, the battery calibration file may have been lost, which is solved by resetting battery statistics or flashing.
Can you replace only the glass, leaving the matrix?
Theoretically, yes, but in practice, it's not practical for the Redmi Note 8 Pro. The OCA laminating requires expensive equipment (separator, laminator, vacuum camera) and skills. It's easier and more reliable to buy a finished module assembled with a frame.
How to check the originality of the display?
The original Xiaomi displays are labeled to match the model code. Also, the original always has uniform backlight, saturated colors and perfect touchscreen performance without delay. Copies often have thicker bezels and a yellowish shade of white.

Use only high-quality adhesive compounds designed for electronics. Conventional superglue (cyanacrylate) releases pairs that settle on the matrix and create a whitish coating, spoiling the image.

Replacing the screen with the Xiaomi Redmi Note 8 Pro is a task that requires patience and accuracy. If you are in doubt, it is better to trust it to the professionals, but with straight hands and a good tool, you can successfully cope with the repair yourself.
