Xiaomi Redmi Note 10 is one of the most popular mid-range smartphones, but even it is not immune to breakdowns. The screen does not respond to touch, the battery is swollen, or the speaker began to wheez? In most cases, repairs can be done independently, saving on the service center. However, the dismantling of the Redmi Note 10 has its own features: fragile plumes, adhesive battery and the risk of damage to flexible plates if you carelessly handle.
In this article, you will find a step-by-step guide with photos of key steps, a list of tools you need, and practical tips on how to avoid typical mistakes. We will learn how to properly remove the back cover, disconnect the battery, dismantle the motherboard and other components without the risk of turning the phone into a brick. If you have never disassembled a smartphone before, start by reading the section on preparation: this will save you nerves and money.
Important: Disassembly will void warranty (if it is still valid).If your Redmi Note 10 is warranty service, first contact your Xiaomi authorized service center.
Preparation for disassembly: tools and security measures
Before you start a screwdriver, make sure you have everything you need. Inappropriate tools are the main cause of damage to the body and internal components. For example, using a metal mediator instead of a plastic one is almost guaranteed to scratch the frame, and a too thick suction cup can crack the glass.
Here is the minimum set you will need for safe disassembly:
- 🔧 Set of screwdrivers (cross-haul) PH00, flat 1.5 mm, five-pointed Y00 screw-tray SIM-map).
- 🧲 Suction cup (diameter 5-7 cm) for removing the back cover. It is better to choose a model with a metal ring.
- 📏 Plastic mediators (2-3 pieces of different thickness) or special blades for disassembling smartphones.
- 🔥 A hair dryer or a thermo-air station (for softening the glue) will suit a household hair dryer with temperature adjustment to 80-90°C.
- 🔋 Isopropyl alcohol (90%+) Cleaning contacts and removing glue residues.
- 📦 Container for screws (or magnetic mat) - in Redmi Note 10 there are more than 15 pieces of different lengths!
Also, prepare your workplace: a clean desk with good lighting, an antistatic mat (if any) and a spare battery in case your family has to unsolve. Don't work on the carpet or the couch - static electricity can damage the motherboard.
⚠️ Warning: If the Redmi Note 10 battery is swelling, don't try to puncture or bend it! The risk of fire is extremely high.
Step 1: Turn off and remove the back cover
The first stage is the most important. The Redmi Note 10 back cover is glued around the perimeter, and it needs to be carefully separated without damaging the plumes underneath. Start by turning off the phone: press the power button and select Turn off. If the screen does not respond, hold the power button for 10-15 seconds until forced shutdown.
Next:
- Heat the edges of the body with a hair dryer (70-80°C) for 1-2 minutes. Keep the hair dryer at a distance of 5-7 cm, evenly driving along the perimeter. This will soften the glue.
- Place the suction cup closer to the bottom edge (where the USB-C connector is). Pull up hard but smoothly, and a gap should appear.
- Insert the mediator into the gap and carefully guide it along the edge, separating the lid. Don't push too hard - the plastic is fragile!
If the lid doesn't lend itself, reheat the problem area. In Redmi Note 10, the fingerprint scanner plume runs under the top left corner, so don't pull it out, or you'll break the contacts.
☑️ Preparation for lid removal
Step 2: Battery disconnection
When you take the lid off, you'll see the battery covered with black film. First rule of repair: always turn off the battery before you run the board!
- Carefully tamper with and remove the protective film from the battery (it is weakly glued).
- Unscrew two screws that fix the metal plate over the battery plume (use the PH00 screwdriver).
- Plastic mediator to raise the battery connector (it is white) and disconnect it from the motherboard.
If the battery is swelling, don't try to pull it out by force, it's glued to double-sided tape.
- 🔥 Heat the case from the back (through the lid) to 60-70°C.
- 🧴 Tap the battery with a plastic spatula and gently pull up, pouring isopropyl alcohol under it to dissolve the glue.
- ⚠️ Do not use metal tools - the risk of short circuit!

Step 3: Dismantling the motherboard
The Redmi Note 10 motherboard is mounted on 12 screws of varying lengths (2 to 5 mm). Remember or photograph which screw you screwed from, and if you confuse it, you can damage the board when you build it. Start by unplugging all the plumes.
| schleife | Location. | Method of disconnection |
|---|---|---|
| Screen + sensor | Upper right corner of the fee | Push the black lock, then pull out the plume. |
| Main camera. | Upper left corner | Pull up carefully (without a fixer) |
| Charging connector | The bottom edge of the fee | Unscrew the metal plate, then disconnect |
| Speaker + microphone | Lower left corner | Smack the white connector with a mediator |
Once the plumes are unplugged, unscrew all the screws and gently raise the charge by the edges. Don't pull the plugs! If the board isn't taken out, check if there's any screw or latch left (the Redmi Note 10 has a hidden latch under the battery).
⚠️ Warning: On the back of the board are antenna contacts for wireless charging (in versions with support for Qi.
Step 4: Replace the screen and sensor
The Redmi Note 10 screen is integrated into a single module, so if you damage the glass or the matrix, they change everything completely.
- Remove the metal frame that attaches the screen to the body (8 screws PH00).
- Heat the display with a hair dryer (temperature 70 ° C) around the perimeter - this will soften the glue.
- Use a suction cup and plastic mediators to gently separate the screen. Start at the bottom edge.
Important nuances:
- 🔧 Screen frame screws of different lengths – remember their location.
- 📱 Screen plume is fragile - don't bend it more than 90°.
- 🔄 When installing a new screen, use a new two-way scotch (e.g., two-way scotch, 3M 9448A).
If the screen does not work after replacement, check:
- Is the plume properly connected (sometimes it is inserted "upside down")?
- Are there any damages on the board contacts (clean them with alcohol if necessary).
- Does the new screen match the Redmi Note 10 model (check the article with the seller).
💡
If you have broken pixels or bands after changing the screen, try reconnecting the plume 2-3 times. Sometimes the contacts oxidize, and just clean them with a stripe (caution!).
Step 5: Camera disassembly and dynamics
The camera module in Redmi Note 10 consists of four lenses attached to a common board.
- Unscrew three screws (length 3 mm) fixing the metal plate above the camera.
- Take the sleeve off carefully (it's short, don't pull too much!).
- Put a plastic blade on the module and pull it out of the nest.
The speaker and microphone are located at the bottom of the phone, to replace them:
- 🔊 Unscrew two screws holding the metal speaker grille.
- 🎤 The microphone is glued - put it on the mediator and disconnect the plume from the board.
- 🔧 When installing a new speaker, check the dust-retardant mesh – it often clogs and lowers the volume.
If the camera is not focusing or if it makes an error after disassembly, the plume or contacts on the board may have been damaged, in which case only replacing the entire module will help.
Assembly of the phone and checking of performance
The Redmi Note 10 is assembled in reverse order, but with a few rules in mind:
- 🔩 Screw the screws cross-cross to avoid skewed fees.
- 📲 Before final assembly, connect the battery and check all the functions: screen, cameras, speaker, sensor.
- 🔋 If the battery is new, charge it to 100% before the first assembly – this calibrates the controller.
Typical errors in assembly:
- 🚫 Forget to connect the fingerprint scanner plume (the phone turns on, but does not recognize the finger).
- 🚫 Retract screws - this can damage the thread in the body.
- 🚫 Do not clean the contacts of old glue, which is why the screen or battery work unstable.
If the phone does not turn on after assembly:
- Check if the battery and screen are properly connected.
- Make sure that all plumes sit tightly in the connectors (sometimes they fall out during transportation).
- Connect the charger – if the charging indicator is on, the problem may be in the power button.
💡
If you have a bug after you build it, you probably have an extra screw or a broken plume, and you take it apart and check all the connections.
