Xiaomi smartphones deservedly popular due to the successful combination of performance and affordable price, but over time, any device requires maintenance. The question of how to disassemble the Xiaomi Redmi Note 8 phone becomes relevant when you need to replace a broken display, a failed battery or cleaning the speaker from dust. Self-repair saves significant funds, but requires accuracy, patience and understanding of the design device.
The process of dismantling the Redmi Note 8 has its own features associated with the use of a plastic back cover and lack of moisture protection, which facilitates access to the insides, but requires caution with the plumes. Before starting any manipulations, it is extremely important to turn off the device and prepare the workplace to avoid losing small screws. In this article, we will take a detailed look at each stage of disassembly, highlight the key nuances and warn about the potential risks so that you can conduct maintenance safely for the gadget.
The Redmi Note 8 is not capable of disassembling properly without the right tools to minimize the risk of damage to the body or electronic components. You will need a set of precision screwdrivers, including the P2 and P00 cross, as well as special suction cups and mediators to open the body. You should not use ordinary household knives or rough tools, as they can leave deep scratches on the plastic or damage the plumes.
The organization of the workspace is just as important as the availability of tools, because a lost cog can make it impossible to assemble the device back. It is recommended to use a magnetic mat or container with cells to sort the fasteners by dismantling stages. Also, remember the bright light source and, preferably, a magnifying glass or a magnifier for working with small connectors.
- 🔧 Setting screwdrivers (P2, P00, flat) - the main tool for dismantling screws.
- 🧲 Magnetic mat or organizer - for systematization of fasteners.
- 🔥 Hair dryer or heating plate - to soften the glue under the screen.
- 📱 Plastic blades and suction cup - for a careful opening of the body.
Special attention should be paid to the condition of the tools: the screwdriver sting must be intact so as not to lick the screw heads, and the sucker must be hermetically attached to the surface. Using a poor-quality tool often leads to damage to the thread or chipped plastic, which complicates further assembly. If you plan to repair often, it makes sense to invest in a professional set.
Removal of the back cover and primary access
The first stage of dismantling Xiaomi Redmi Note 8
⚠️ Warning: Do not overheat the body too much, as plastic can deform and internal components can suffer from high temperatures.
After warming up, insert a suction cup at the bottom of the back cover and pull up slightly to create a gap. Insert a plastic mediator into the resulting gap and, as you slid along the perimeter, snap the clips and separate the lid from the frame. Move slowly, trying not to damage the fingerprint scanner plume if it is glued to the lid, although in this model it is often integrated into the side button.
What to do if the lid does not open?
If the lid fails to warm up after the lid is heated, don't use force. Add a little more heat, but watch the temperature. You can use a special adhesive solvent (such as a B-7000 or isopropyl alcohol), carefully introducing it into the slit with a thin needle to dissolve the adhesive layer. Be careful not to let the liquid get inside on the board. Successful removal of the lid opens up access to the main board, the battery and the camera module, but do not rush to disassemble further. Carefully inspect the insides for visible damage, the battery, after you open the main plate, or the main plate is already clear from the mounting stage, after you have enough access to remove the main components. To remove it, you need to twist out several screws located around the perimeter and in the center using a screwdriver marked P00. It is important to remember the order of twisting the screws, as they can be of different lengths, and to confuse them means to damage the board when assembly. The key is to properly disable the plumes, since careless handling leads to a break in the contacts. The first thing you need to turn off the battery to de-energize the device and avoid short circuit. To do this, carefully tuck the battery connector with a plastic blade, trying to avoid damaging the board itself.

Use plastic cards or special tapes to safely extract the battery, gradually separating the glue from the case. The lower board on which the charging connector is located USB The Type-C and microphone are mounted with multiple screws and connected to the main board by a plume, and when replacing this module, it is important to properly place the plume in the guide channels so that it does not rub or clamp when assembled. Often the problem with charging is solved by replacing this part or cleaning contacts from oxidation. 🔋 New battery – make sure the voltage and capacity match the original. 🧹 Isopropyl alcohol - for cleaning contacts and removing glue residues. 🩹 Double-sided Scotch – for reliable fixation of the new battery. 🔌 Charging module – it is better to use the original or high-quality analogue. ⚠️ Warning: Never break or bend the battery, which can cause instantaneous ignition of the lithium electrolyte, and the new battery is installed in reverse sequence: You degrease the surface, you put on a new tape, you put in a battery, you plug in a connector, and then you can set the bottom board, you can straighten the plumes carefully and lock them with screws. Make sure all screws are twisted to the end, but without excessive effort to avoid breaking the thread in the plastic. 📊 What most often fails in Redmi Note 8?Scrashed screen:Battery:Not working charging:Problems with the speaker Removal and replacement of the display module Replacement of the screen on Xiaomi Redmi Note 8 is one of the most difficult procedures, as the display module is glued around the perimeter to the plastic frame. The main board, battery and vibrator must be removed to take access to the screws holding the display frame. After unscrewing all the fastening elements, the screen frame is separated from the rest of the case. The old broken screen is separated from the frame by heating and a thin string or blade, after which a new module is glued to the cleaned frame. The display glue (B-7000 or analog) is applied in a thin layer along the perimeter, after which the module is tightly pressed and fixed with rubber bands to the payline to the plate, after the snapping of the new slabel is so installed, the device can be re-upped to the sor the device, after the slashing of the display is so that the device is not slit the wired to the device to the wiring wiring wiring wiring wiring wiring wiring wiring wiring wiring wiring wiring wiring wiping wiring wiping wiring wiring sle or resetting. Before the final assembly of the body, it is recommended to conduct a test turn on to ensure the performance of the touch and image. 💡Quality replacement of the screen is possible only with a complete cleaning of the frame from the old glue and the use of a good adhesive, otherwise the module will backfire or peel off. The final stage - the assembly of the Redmi Note 8 - requires care to remember to connect all the plumes and twist all the screws. Start by installing the main board, connecting the battery and checking the on and volume buttons. Make sure all connectors are snapped to the characteristic clicks and the plumes lie flat, without clatters.The back cover is installed in place after pre-application of a new layer of glue or use of special adhesive tapes around the perimeter. Press the lid tightly on all sides and, if necessary, put the phone under the press (or under a stack of books) for 15-20 minutes for better adhesion. Don't turn the device on immediately, let the glue grab a little. After assembly, perform a full functionality test: check the operation of the cameras, speakers, microphone, Wi-Fi, Bluetooth and fingerprint sensor. If all systems work correctly, you can consider the repair successfully completed. If you find faults, you will have to re-disassemble the device to find the cause. What to do if the phone does not turn on after assembly? First of all, check the circuitry, as well as the circuit board, they often help with the switch on the circuit, and make sure that the circuitry in the circuitry, they did not have a circuitry, if they did not check the circuitry in the circuit, if the circuit, they did not use the circuit, and make sure that the circuitry, they did not use the circuitry, if they did not use the circuitry in the circuitry, they were damaged in the circuitry, and if they did not use the circuitry, they did not use the Can you disassemble the Redmi Note 8 without a hair dryer? Theoretically, it's extremely risky: the plastic of the back cover can crack, and the adhesive layer will break unevenly. The hair dryer or the heating plate significantly reduces the force required to open, making the process safer for the body and internal components. Which glue is better used to glue the screen? The optimal choice is the glue gel B-7000 or T-7000, which remains elastic after drying and allows you to disassemble the device again if necessary. Superglues can not be used, as they can become brittle or damage the matrix.
