Disassembly of the smartphone Xiaomi Redmi Note 8 Pro can be required for various reasons: from the banal replacement of broken glass display to install a new battery or cleaning the speaker. This model, despite its popularity, has a rather complex design with glued elements, which requires the master to be more accurate and have a special tool. Any careless movement can lead to damage to the internal plumes or violation of the tightness of the case, so before starting work it is important to clearly imagine the sequence of actions.
The main challenge is to remove the back cover, which is attached to a powerful layer of glue, and carefully disconnect the numerous connectors. The interior space of the Redmi Note 8 Pro is tightly packed, and the camera module protrudes quite significantly, taking up a lot of space. You will need patience, since rush here is the main enemy of successful repairs. Next, we will take a detailed look at each stage of the dismantling so that you can perform the procedure safely for the device.
Tools and workplace preparation required
Before starting to disassemble the Xiaomi Redmi Note 8 Pro, you need to prepare the workplace. It should be well lit and free of unnecessary objects, so that small screws do not get lost. The optimal solution is to use a special mat to repair electronics with sections to sort the fasteners. Without proper preparation, the process can be delayed, and the risk of losing parts will increase many times.
To work, you'll need a specialized toolkit that includes not only screwdrivers, but also means to safely open the case. A standard home kit may not be enough, especially if it's about warming up the adhesive layer. Ignoring this step often leads to chipping on the glass or damage to the frame.
- 🔧 Screwdriver kits: cross (PH00, PH000) and hexagonal (for some screws frame).
- 🔥 Hair dryer or heatplate: for uniform heating of the perimeter of the back cover to the temperature 80-90 degree.
- 🃏 Plastic cards and mediators: for careful peeling of the cover without damaging the body.
- 🧲 Magnetic mat or organizer: for systematization of screws of different sizes.
- 🧤 Suction: to create an initial gap between the lid and the frame.
⚠️ Warning: Never use metal blades or knives to pluck the back cover.The metal can damage the plume of the fingerprint scanner that runs directly under the glass, or break through the battery, causing a fire.
Removal of the back cover and protection of components
The first and most important step is to dismantle the back, and the Redmi Note 8 Pro is assembled on double-sided tape around the perimeter, which softens when heated, allowing the device to open, starting with turning off the smartphone and removing the tray. SIM-cards to avoid short circuits or software failures in the process.
After removing the sim tray, turn on the dryer at average power and evenly warm the perimeter of the back cover for 2-3 minutes. Do not keep the hot air flow at one point for too long so as not to overheat the display matrix on the back side or the battery. Periodically check the temperature with your finger - the glass should become hot, but not burning.
Once the glue has softened, place the suction cup at the bottom of the lid, closer to the center, and pull up slightly, creating a small gap. In the resulting gap, carefully insert a plastic card or a thin mediator. Lead the tool along the perimeter, cutting the glue layer in translational movements, trying not to plunge the map deep into the interior so as not to touch the internal components.
💡
If the back cover cracked when removed, before installing a new one, be sure to remove all the fragments of the old glue from the frame, otherwise the new panel will lie loose and will backlight.
Be very careful on the top of the smartphone, where the main camera module is located. The fingerprint scanner plume is glued to the inside of the glass and is very short in length. A sharp opening of the lid at a large angle is guaranteed to cause this plume to break, after which the fingerprint scanner will cease to work.
Dismantling internal protection and disconnecting plumes
When you successfully remove the back cover, you'll see the inside of the smartphone, closed by a plastic shield, mounted by a lot of screws of different sizes that need to be twisted and laid out in a strict manner, and the chaotic folding of the screws will cause the long screw to be screwed into a short hole when you build it, which can cause the motherboard to break down.
Carefully remove the plastic pad, putting it on a plastic blade around the perimeter. Under it are the main nodes: battery, motherboard, main camera module and dynamic module. Before any physical impact on the components, you need to turn off the device by disconnecting the battery plume from the mother---WIDGET:checklist:Switch off:Deactivate battery plume |Remove the protective metal plate |Deactivate the display and cameras plumes |Extract the vibrator and speakers--->
First, the battery connector is disconnected, which is a critical step to keep things safe. Once the power is turned off, you can remove the metal shielding plate that covers the connectors of the display and the cameras. The screws of this plate are also of different lengths, so be careful when you unscrew them.
Then the main camera, wide-angle camera and macro plumes are sequentially turned off, they are of different sizes and locations, but they require the same gentle handling. The camera plumes are very thin and easily torn when sloppyly removed from the connector. Use a plastic blade to gently lift the connector up.
| Component | Location. | Type of attachment | Features |
|---|---|---|---|
| Battery | The bottom part | Glue base + connector | Requires warm-up to take off |
| Main camera. | Upper left corner | Planting place + train | Exceeds above the pay level |
| Display module | The front | Perimeter glue | The plume goes on pay. |
| Charging charges | The bottom part | Screws + connector | Linked by the main plume |
Replacement of the battery and work with adhesive bases
In the Xiaomi Redmi Note 8 Pro, the battery occupies a significant part of the internal volume and is attached to a powerful layer of glue. To remove it, you must first remove the plastic speaker cover located at the bottom of the smartphone.
To remove the old battery, it must be warmed up. Use a hair dryer by directing the flow of hot air to the battery area through the open back cover (if you have not removed it completely) or through the hole after removing the bottom cover. The temperature should not exceed 60-70 degrees, so as not to damage the battery itself and cause it to bloat.
⚠️ Attention: It is strictly forbidden to use metal tools to tamper with the battery. Puncture of the lithium polymer battery will lead to instant ignition and release of toxic substances. Use only plastic blades and special suction cups.
After warming up, insert a plastic card between the battery and the frame, trying to keep it parallel to the plane of the phone. Move the card in reciprocal motions, gradually cutting the adhesive layer. If the battery sits very tightly, add a little more heat, but do not overdo it. After removing the old battery, clean the frame of glue residue with alcohol or a special solvent.

Dismantling of the display module and the main board
Replacing the screen with the Redmi Note 8 Pro is one of the most common reasons for disassembly: the screen is mounted around the perimeter on the glue, and its plume passes through the cutout in the metal frame and connects to the board on top. To replace the module, you often have to remove the motherboard, because access to the screen mount is limited.
First, you need to unscrew all the screws that attach the motherboard to the case. Notice the screws around the charging connector and the dynamic module. After you unscrew all the screws, the board can still hold on to the plumes. Carefully raise the board, checking if all the connections are broken.
The display plume runs under the camera and the power supply, so it often requires removing or temporarily displacing other components to fully remove it. Be extremely careful with the touchscreen plume, which is very sensitive to crunch. When installing a new module, be sure to check its performance before the final sticking.
The new display module should be tried on, making sure there are no gaps. Before the final assembly, apply a new adhesive compound (B-7000 or a special adhesive frame) around the perimeter of the housing, which will ensure the necessary tightness and protection from dust.
Assembly of the device and verification of functionality
The Xiaomi Redmi Note 8 Pro is assembled in reverse order. Start by installing the motherboard and connecting all the plumes. Make sure each connector falls into place with a characteristic click. A loosely connected display plume can result in no image or bars appearing on the screen.
After all the internal components are connected, but before the screws are twisted and the back cover is glued, you need to perform a primary test. Connect the battery and press the switch on. If the smartphone is turned on, check the sensor, cameras, speakers, microphone and vibrator.
- 📱 Display Check: No Broken Pixels and Response to Touches Throughout the Area.
- 📸 Camera Test: Focusing, Flash Operation and Switching Between Lenses.
- 🔊 Sound: music playback, voice recording, conversational speaker work.
- 📶 Linkage: definition SIM-maps, signal level, Wi-Fi and Bluetooth.
💡
The final check of all functions before sealing the case is a mandatory step, which will save you time for re-disassembly in the event of a defect.
If all the tests are successful, turn off the phone, turn off the battery (if required to install the lid), and swivel all the screws into their seats. Then apply glue to the frame of the back cover and press it tightly. For better fixation, you can use rubber bands or a special press for 15-20 minutes.
