How to disassemble Xiaomi Redmi: remove the back cover without breakdowns

Replacing the battery, cleaning the dust, or repairing the camera are common reasons Xiaomi Redmi owners have to remove the back cover. But the design of modern smartphones is far from the modular Nokia of the early 2000s: there are no removable panels on the latches, and the body is sealed and held together by dozens of hidden clips. One wrong move will crack on the plastic and the glass will split.

This article will help avoid errors, and we will take a look at all the steps of the process, from tool preparation to finishing, take into account the features of different Redmi models (from Note 10 Pro to Redmi 12), and also warn against typical pitfalls. Glass rear panels of models 2022-2026 require heating to 80-90°C - at a lower temperature, the glue will not soften, but at a greater temperature it will damage. OLED-screen.

If you've never taken a smartphone apart, you'd better go to the service, but if you've decided to do it yourself, follow the instructions carefully: every step is important.

What tools will you need

Without a dedicated kit, it is almost impossible to disassemble the Xiaomi Redmi.

• 🔧 Plastic mediators (2-3 pieces) - to separate the cover and the body. Metal blades scratch the frame.
• 🔥 A hair dryer or a thermo-air station to soften the glue, the hair dryer's power must be at least 1,600 watts.
• 🧲 Suction cup (diameter 4-5 cm) - helps to lift the lid after heating. Alternative: wide scotch.
• 🔍 A magnifier or magnifying glass – to see microclips and cables.
• 📏 Thin plastic scraper - to remove glue residues.
• 🧴 Isopropyl alcohol (90%+) — cleansing surfaces of glue before gluing.

For models with glass back panel (for example, Redmi Note 11 Pro)+) need to:

• 🧊 Gel packs – to cool the screen while the cover is heated (prevents damage) OLED).
• 🛡️ Protective film – pasted on the screen before work to avoid scratches.

Don’t use knives, screwdrivers or other metal objects, they will damage the body, and avoid cheap Chinese mediators, which often break inside the smartphone.

Preparing the smartphone for disassembly

Before removing the cover, follow the mandatory steps:

Turn off your smartphone and remove it. SIM-memory-card|Charge the battery to 30-50% (full charge is dangerous when heated)|Remove the cover and protective glass (if any)|Take a picture of the location of the screws (if you have already disassembled)|Place your phone on a soft surface (a towel or silicone mat)-->

Pay special attention to the battery. If it's swelling, don't heat the smartphone! Risk of lithium-ion batteries ignition at temperatures above 60°C is very high. In that case, you should contact the service immediately.

Also check if Find My Device is activated (in Settings). → Google → If the smartphone does not turn on after disassembly, this feature will help restore access to the account.

⚠️ Note: If your Redmi has factory graphics film installed (e.g., on the Redmi Note 12 Pro Speed), it cannot be heated above 70.°C, it melts and it sticks to the transmitter. Take the tape in advance.

Step-by-step: how to remove the back cover

The disassembly process can be divided into 4 key stages:

1. Heating the body - softening the glue.
2. The lid separation is a neat undermining by the mediator.
3. Disconnecting plumes – if the cover is connected to the board (relevant for Redmi) K50 newer).
4. Cleaning and preparation for the reverse assembly.

Let’s look at each stage in detail.

1. Heating of the shell

Use a dryer at the minimum air speed but the maximum temperature (if there is an adjustment) and keep it 5-7 cm from the back cover, evenly pacing the surface.

• Plastic cover: 2-3 minutes.
• Glass cover: 4-5 minutes (up to a temperature of 80-90)°C).

To check the temperature, you can use an infrared thermometer or water droplets: if they hiss and evaporate when you touch the cover, the glue has softened.

💡

If you don't have a thermometer, heat the lid to a point where you can't hold it with your hand for longer than 2-3 seconds, signaling that the glue is ready to separate.

2. Separation of the cover

Once heated, immediately attach the suction cup to the top of the lid (near the camera) and pull up. If the lid fails, do not apply force! Reheat for another 1-2 minutes.

Once the gap is in, insert a plastic mediator into it and slowly lead along the edge, separating the clips. 10/11 The clips are located on the perimeter, and on the Redmi 12 — And in the middle (under the logo).

Be careful in the zone:

• 📷 Camera module - flexible plumes pass here.
• 🔋 Battery – don’t press it with a mediator.
• 📶 Antenna lines (thin metal stripes at the edges).

3. Disconnection of plumes (if any)

On some models (e.g. Redmi) K60) the back cover is connected to the motherboard with a flexible plume for NFC If you pull the lid with force, the plume will break.

To avoid this:

1. After the lid is removed, find the plume (usually at the top).
2. Carefully tuck it with a plastic spatula and disconnect.
3. Remember the location - when assembled, the plume should stand back without inflections.

4. Cleaning and assembly preparation

Once the lid is removed, remove the glue residue from the case and the lid itself.

• Isopropyl alcohol - for dissolving glue.
• Soft brush - for cleaning dust from connectors.
• Scotch or double-sided tape – if you plan to glue the lid back without new glue.

For reliable fixation, it is recommended to use a special glue for smartphones (for example, B-7000 or T-7000). Apply it in a thin layer around the perimeter of the lid, avoiding hitting speakers and microphones.

💡

On Redmi models with wireless charging (for example, Redmi Note 12 Pro)+) The glue is applied point-by-point - otherwise the charging coil will not work.

Features of disassembly of different models Xiaomi Redmi

The design of the lid depends on the series and year of release, and the table below shows the key differences:

For models with IP53-protection (e.g. Redmi Note) 11S) After disassembly, you will need to replace the sealing pads, and you can buy them in repair kits on AliExpress or in specialized stores.

Common Mistakes and How to Avoid Them

Even experienced craftsmen sometimes make mistakes, and here are the most common ones:

• 🔥 Overheating of the screen - leads to yellow spots on the OLED (Burn-in defect: Always use gel packs for cooling.
• 🔧 Using metal tools – scratches the frame and leaves a shaving that can close the contacts.
• 🧲 Strong suction of the vacuum suction cup - on glass covers can cause cracks.
• 🔋 Battery damage -- if you puncture it, it can ignite. Never press on swollen areas.
• 📶 The breakdown of the antenna plumes leads to loss of the network. Before disassembling, study the layout of the plumes for your model.

Another common problem is the wrong assembly. If the lid is replaced, check:

1. Are all the plumes connected (especially the battery and display)?
2. No clamping on the flexible cables.
3. Whether the cover fits tightly – if there are gaps, antenna contacts may not work.

⚠️ Note: Redmi models with an infrared port (such as the Redmi Note 10 Pro) may stop working after disassembly, due to damage to the IR emitter, which is located under the top of the lid.

How to put the lid back together: the best options

The glue you choose will determine the tightness and strength of the structure, and here are the proven options:

For models with water protection (for example, Redmi Note 12 Pro)+) Make sure to use a sealant (for example, LOCTITE 577) for sealing joints, without it, protection IP53 will be broken.

When applying glue, follow the rules:

• 🎨 Apply a thin layer (0.5-1 mm) around the perimeter of the cover.
• ❌ Avoid getting into speakers, microphones and connectors.
• ⏳ Let the glue dry 5-10 minutes before final assembly.

When is the best time to contact the service

Some situations require professional intervention. Contact a service center if:

• 🔧 You need to replace the battery with adhesive-mounted models (e.g. Redmi). K60). The risk of damage to the board when self-replacement is very high.
• 💧 Smartphone hit the water – corrosion on the board can be invisible, but will lead to a short circuit.
• 📱 The screen does not respond to touches after disassembly – this may indicate damage to the display plume.
• 🔋 The battery is swollen - its replacement requires special equipment and safety knowledge.
• 📡 After assembly, the network or Wi-Fi is not working – most likely, the antenna is damaged.

The cost of dismantling in the service varies from 500 to 2000 rubles, depending on the model and complexity of the work.

• Replacement of the back cover with Redmi Note 10 — ~800 rubles.
• Redmi's disassembly K50 plume-off — ~1500 rubles.
• Diagnosis after unsuccessful self-disassembly — ~1,000 rubles.

If you do decide to do it yourself, but something went wrong, don't try to do it. You better consult a specialist before the damage becomes critical.
