How to carefully remove the back cover from Xiaomi Redmi: instructions with photos and warnings

Disassembling the Xiaomi Redmi smartphone is a challenge that owners face when replacing the battery, repairing plumes or cleaning dust. However, improper removal of the back cover can lead to cracks in the case, damage to the adhesive layer or even failure of touch buttons. In this article, we will analyze three officially approved methods (for glue, snapping and screw covers), list the necessary tools and warn of typical errors that beginners make.

It's important to understand that the design of the lid depends on the Redmi model and the year of release. For example, the Redmi Note 10 Pro has a fully glued panel, whereas the Redmi 9A has a combination of latches and glue. We analyzed 15 popular models (2019-2026) and identified universal steps that will work for most devices. If you've never taken a smartphone apart, start by preparing the workplace and study the FAQ section, where you'll get a lot of questions.

1.Preparation: tools and safety

Before you start disassembling, make sure you have everything you need, and even one tool that is missing can cause permanent damage to the body or internal components, and here's the minimum set:

• 🔧 Plastic blade (or mediator) - to separate the lid and the body. Metal tools are prohibited!
• 🔥 Construction dryer (or thermo-air station) - for softening the glue. Optimal temperature: 60-80°C.
• 🧲 Suction cup (3-5 cm diameter) - helps to lift the cover after heating.
• ⚡ Screwdriver. T3/T4 — For screws (if you have them in your model).
• 📦 Container for screws - so as not to lose small details.

Also prepare the workplace:

• ✅ Lighting: bright lamp or table lamp.
• ✅ Surface: soft substrate (e.g., silicone mat).
• ✅ Protection: Turn off your smartphone and remove it SIM-map + memory-card.

⚠️ Note: If your Redmi is warranty-free, self-disassembly will void it. The manufacturer uses special seals on the screws that break when unscrewed.

💡

Before heating, paste the screen with tape - this will protect it from accidental scratches when the shoulder blade slips.

2. Determine the type of mounting of the lid

The design of the rear panel on Xiaomi Redmi varies depending on the series and year of release. Below is a table with the distribution by mount types:

To determine the type of attachment of your model:

1. Look at the bottom end of the case - if there are screws under the stickers, they need to be twisted out.
2. Try to easily press the lid near the seam - if it bends, there are likely latches.
3. For models with a glass rear panel (for example, Redmi Note 11 Pro+), the adhesive is always used.

3. Step-by-step instructions for adhesive covers

This method is suitable for most modern Redmi (Series Note, K, Pro). the main difficulty is to evenly heat the glue without overheating the battery.

Warm up the hair dryer around the perimeter (30-40 seconds)

Stick the suction cup at the bottom

Carefully pull the sucker up, creating a gap

Insert a plastic shoulder blade into the gap

Conduct the blade along the body, separating the glue

-->

Step 1. Heat. Turn the dryer on to the minimum power and direct the air flow to the edge of the cover (not the screen!). Keep it at a distance of 5-7 cm, constantly moving the hair dryer around the perimeter. Heat time: 1-1.5 minutes.

Step 2: Separate the lid. Stick the suction cup closer to the bottom edge (where the charging connector is located) and pull up. Once you have a gap of 1-2 mm, insert a plastic spatula.

Step 3. Perimeter pass. Slowly drive the blade along the body, separating the glue. If the lid fails, heat the problem area again. Don't force it! - this can lead to cracks.

⚠️ Attention: Redmi models K50 Note 12 Pro+ And there's an antenna grid underneath the lid, glued to the body. Don't pull it, just gently separate it with a spatula.

Step 4: Remove the glue residue, and after the lid is removed, the frame will have traces of glue, which can be removed.

• 🧴 Isopropyl alcohol (90%+ concentration).
• 🧼 Soap solution and soft brush (for plastic cases).
• 🔥 Dryer (heat and scrape off with a wooden stick).

Disassembly of the latches (without glue)

Redmi 9A, Redmi 8A and some budget options have plastic latches, so the key is not to break the clips, otherwise the lid will hang.

Step 1: Unscrew the screws. Turn the phone over and remove the stickers at the bottom (the screws are hidden below). Use a T3 or T4 screwdriver (depending on the model).

Step 2. Put the lid on. Put the plastic blade in the gap between the lid and the body (start at the lower right corner). Keep the blade gently along the edge until you hear the flicks of the reflective latches.

Step 3: Remove the lid. Once all the clips are snapped, lift the lid off the end. Don't pull it too hard, because there may be plumes (like a fingerprint scanner) stuck inside.

⚠️ Attention: Redmi's 9C redmi A1 The latches are not evenly positioned, there are more latches at the top.

💡

You can remove latch covers without heating them, but you're more likely to break clips, and if you're not sure, use a dryer at the lowest temperature to soften the plastic.

5. Common Mistakes and How to Avoid Them

Even experienced craftsmen sometimes make mistakes when parsing Xiaomi Redmi.We have collected the TOP-5 problems and ways to prevent them:

• 🔥 Battery overheating – keep the hair dryer at a distance and do not direct airflow to the center of the cover.
• 🔪 Using metal tools – even a small scratch on an aluminum frame can become a hotbed of corrosion.
• 🧲 Losing screws – fold them in a magnetic container or glue them to scotch in order of twisting.
• 📱 Damage to the plume of the fingerprint scanner - before removing the cover, check if it is glued.
• 💧 Getting alcohol on the screen - when cleaning the glue, use a brush, not cotton discs.

If you've already made a mistake:

• 🔋 Battery swollen after heating? immediately turn off phone and don't use it.Bloated battery is risk of fire.
• 🔊 Check if the plume or the antenna contact pad has come off.
• 📲 The screen is glitching, the display plume may have been damaged, it needs diagnostics in the service.

6 How to put the phone back together

Assembling Xiaomi Redmi after repair is no less responsible process than disassembly.

1. Contact cleaning: Before installing the cover, wipe the contact areas (for example, for an antenna or fingerprint scanner) with alcohol solution.
2. Apply new adhesive. Use 3M 9448A double-sided tape or B-7000 liquid glue for adhesive caps. Apply thinly, avoiding speakers and microphones.
3. Closing the lid. Start at the top, gradually pressing the lid against the body. Use a press (such as a stack of books) for 10-15 minutes to stick evenly.
4. Functional check. After assembly, turn on the phone and check: fingerprint sensor performance, communication quality (antenna), speaker and microphone sound.

⚠️ Warning: If the phone doesn't turn on after assembly, check: Is the battery connected (sometimes the plume leaves when the lid is installed), is the contacts on the motherboard closed (check visually), has the glue on the connectors.

7. Alternative methods (for experienced)

If standard methods have not worked (e.g., glue is too strong), alternative methods may be used. Use them at your own risk!

• 🧊 Freeze method. Put your phone in the freezer for 10 to 15 minutes. The glue will become brittle and the lid will be easier to separate. Risk: condensation can damage the board.
• 🧴 Apply acetone or white spirit around the perimeter of the lid (plastic case only!) Risk: damage to the paintwork.
• 🔪 Nichrome thread. Warm up the thread and run it under the lid, melting the glue. Risk: overheating of the internal components.

Models with a glued screen and lid (such as the Redmi Note 11S) may require a special machine to separate the panels, which is almost impossible to do without damage at home.

💡

If you plan to disassemble your phone frequently (for example, for upgrades), replace the factory glue with magnetic latches, which you can buy on AliExpress and install instead of the standard mount.
