Disassembling a smartphone is a process that requires not only technical skill, but also an understanding of the internal architecture of the device. Xiaomi Redmi 10 model has a typical budget design, but access to internal components here is limited by the use of adhesives and screws under non-standard heads. Before starting work, it is important to understand that opening the case automatically leads to the loss of official warranty, so weigh all the risks.
The main difficulty is the careful separation of the back panel, which in this model is glass and is attached to double-sided tape around the perimeter. Careless handling of heating elements or excessive force when bending can lead to cracks or damage to the plumes. Careful preparation of the workplace and the availability of specialized tools is the key to the successful completion of the operation without fatal errors.
In this guide, we will take a detailed look at each step of dismantling, from heating the case to turning off the plumes, you will learn which screws to unscrew first and how to safely disconnect the battery so as not to cause a short circuit on the board.
⚠️ Warning: Any manipulation inside the case of the switched-off device risks damaging the lithium polymer battery, and if the battery is punctured, a chemical reaction with smoke or fire may occur.
The process begins with the complete switching off of the smartphone and removing the tray. SIM-This is a critical step, because a forgotten SIM card can block access to the screws or be damaged during disassembly, and then you need to prepare the surface by covering it with an antistatic mat or clean fabric so that small details are not lost.
Tools and workplace preparation required
To properly disassemble the Redmi 10, a regular set of screwdrivers will not be enough. You will need specific tools that allow you to work with Torx screws and carefully tweak plastic latches. Lack of the right tool often leads to licking of the screw caps, which makes simple repairs a difficult task to drill the fasteners.
Pay special attention to the heating source. Using an open fire or too powerful industrial hair dryers is unacceptable, as it can damage the display matrix or melt the internal plastic elements of the case. The optimal temperature for softening the adhesive is 80-90 degrees Celsius.
- 🛠️ A set of precision screwdrivers (mandatory presence of bits) T5 cross-block P2)
- 🔥 A hot water heater for phones or a hair dryer with temperature adjustment
- 🎴 Plastic blades and mediators for opening the body
- 🧲 Magnetic mat for sorting screws of different sizes
Space organization is key. All screws should be arranged in a strict sequence of their extraction. Modern smartphones use screws of different lengths, and placing a long screw in the hole for a short one can lead to a failure of the PCB or damage to the inner layers of the screen.
Removal of the back cover and primary access
The first step is to heat the perimeter of the back cover, warm the end of the device evenly for 2-3 minutes, constantly checking the temperature with your finger to avoid overheating the glass, and once the body becomes warm to the touch, you can start creating a gap.
Use a suction cup to create a micro gap between the frame and the glass, then carefully insert a plastic mediator. Drive the tool along the perimeter, cutting the adhesive layer. Do not plunge the shoulder blade deep so as not to damage the tail of the side button or speaker located at the bottom.
Features of the glue composition
Once you successfully remove the lid, you will have access to the main board, the battery and the camera module. Notice the location of the screws that lock the decorative bar that covers the main connections. Some screws may be hidden under stickers or plugs.
| Type of screw | Location. | Tool. | Note |
|---|---|---|---|
| Torx T5 | Lower frame (2 pcs) | Screwdriver T5 | Locking down the lower part of the body |
| P2 Cross Cross | Battery protection fee | Screwdriver P2 | It requires care. |
| Torx T5 | Maternity board anchorage | Screwdriver T5 | Different lengths of screws |
| P2 Cross Cross | Camera module | Screwdriver P2 | Very small screws. |
Dismantling protective screens and disconnecting plumes
Once the back panel is removed, the plastic protective lining that covers the plume connectors must be removed, and it is usually attached to several screws around the perimeter and sometimes fixed to adhesive strips, and removed slowly, controlling the force.
The most important thing in the whole procedure is to turn off the battery, so before you touch any other components, find the battery connector and gently disconnect it with a plastic blade, which will turn the device off and minimize the risk of short circuit when working with other plumes.
⚠️ Warning: Never try to disable the plumes by pulling them by the wires. Take a hard plastic connector and pull strictly up or sideways, depending on the type of latch.
Then, the display, touchscreen, main and front cameras, and charging module are sequentially turned off. To remember the location, you can take a photo of the board before you start turning off. The display plumes are particularly sensitive to clamps, so you need to work with them with extreme care.
☑️ Disconnection procedure
When removing protective metal screens on the motherboard itself, use only plastic tools. Metal objects can slip and damage small ones. SMD-components or capacitors that make repairs economically inefficient.
Replacement of battery and battery
The battery in Redmi 10 is glued to the frame of the case is quite tight. To remove it, you will need to use heating again, but already directed to the bottom of the device, where the battery is located. Warm up the area around the battery for 3-4 minutes.
Use a suction cup or a thin line/plastic card to separate the battery. Strip the tool between the battery and the frame, trying not to damage the battery cell itself. If you damage the battery shell, its use will become dangerous.
When installing a new battery, be sure to apply a new layer of glue or use special adhesive tapes (B-7000 or analogues) to lock the battery.
💡
Before installing a new battery, check its voltage with a multimeter. If the voltage is below 3.5V, it is advisable to charge the battery with an external source before connecting to the board.
After installing a new power source, take your time to close the case, connect the battery plume to the board and check if the device is responsive to the charger, which will ensure that the new component is healthy before the final assembly.
Replacement of the display and touch screen
In the Xiaomi Redmi 10, the screen is assembled with a frame, which makes it much easier to replace the screen, you don't have to separate the matrix from the glass, risking crushing it, but the process requires completely removing all the internal components and transferring them to a new frame with the screen.
Start by removing the control board, dynamic speaker and vibrator from the old frame. Gently uncouple the elements using heating, and immediately fix them on the new frame. Pay special attention to the speaker grid, which is often glued and can break.
When you move the main camera module, make sure the lenses are clean. Dust trapped under the camera glass will create black spots in all the photos. If the camera is modular, just rearrange the entire unit.
💡
Replacing the screen assembled with a frame is a more expensive, but reliable way of recovery, preserving the factory tightness and geometry of the body.
Once you've moved all the components, put the device back together, but don't stick the back cover on yet, turn on the phone and check for the touchscreen in all corners, and check for broken pixels on the matrix, and only after you've made sure that it's working, you can start the final fixation.
Assembly of the device and verification of functionality
The final step is to assemble all the nodes in reverse order, make sure that all the plumes are snapped to a characteristic click and fixed with clamping slats, and an untied screw on the clamping bar can cause Worke to crash the touchscreen or communication module.
The back cover should be cleaned of the residue of old glue before installation. Use isopropyl alcohol and a plastic blade to remove contaminants. Apply the new B-7000 adhesive with a thin layer around the perimeter or use a pre-cut adhesive.
⚠️ Warning: Let the glue dry during 15-20 minutes before application, and after assembly, fix the body with rubber bands on 1-2 hour for full polymerization of glue.
Once assembled, perform a full test of functionality: check microphones, speakers, vibration, Wi-Fi and cellular. If all systems are working correctly, repairs can be considered successful.
