Disassembly Xiaomi Redmi 6A: how to remove the back cover without damage

Xiaomi Redmi 6A remains a popular choice among budget devices even years after its release, its reliability and maintainability allow you to extend the life of the gadget yourself, whether it is replacing a dead battery, cleaning from dust or repairing a speaker. However, disassembling the case is the first and most important step, where a mistake can cost a broken latches or a damaged plume.

Many users are afraid to disassemble the Redmi 6A because of rumors about a “disassembled” body or the risk of damaging antenna lines. In fact, with the right approach and a minimum set of tools, you can remove the lid in 10-15 minutes. The main thing is to understand the design features of the model: there is no removable battery, like in old smartphones, and the back panel is attached to latches and glue. In this article, we will analyze three proven methods of disassembly, assess their pros and cons, and also explain how to avoid typical errors.

If you've never taken a smartphone apart before, don't worry: the Redmi 6A is one of the friendliest models for beginners, but remember that even a minor oversight (such as excessive effort to unplug the plume) can lead to a loss of warranty (if it's still valid) or component failure. Before you start, evaluate your strength and prepare the workplace.

Preparation for disassembly: tools and security measures

Before you pick up the screwdriver, make sure you have everything you need. The Redmi 6A's minimum disassembly toolkit includes:

• 🔧 Plastic mediator or guitar mediator (thickness 0.3–0.5 mm) – for separation of the body.
• 🔨 The screwdriver (PH00 or PH0) — screw-twisting.
• 🧲 Suction (optional) - helps to lift the cover after heating.
• 🔥 Hair dryer or thermo-air station - for softening the glue (temperature not higher than 60)°C!).
• 📦 Container for screws - so as not to lose small details.

⚠️ Warning: Never use metal tools (knives, blades) to separate the body! They easily cut through plastic and damage antenna lines under the lid. Also avoid overheating - if the glue does not lend itself, repeat the heating procedure rather than increase the temperature.

The workplace should be well lit and free of static electricity. Put a clean cloth or silicone mat on the table so you don't scratch your smartphone. If you're working with a battery, remember that even when it's off the board, it can keep a charge -- don't puncture it or put it under mechanical stress.

💡

Before disassembling, take a picture of the location of all the plumes and screws, which will help to assemble the smartphone back without errors, especially if you are a beginner.

Method 1: Unheating without heating (for beginners)

This is a good way to do it if the glue on your Redmi 6A hasn't dry yet (like a new smartphone or a recent one), and the advantage is that it has minimal risk of damage to components because it doesn't use high temperatures, but it does require patience and care.

Algorithm of action:

1. Turn off your smartphone and remove it. SIM-scatter-card.
2. Insert a plastic mediator into the gap between the back cover and the frame of the case. Start with the lower left corner (there are usually fewer latches).
3. Carefully drive the mediator along the edge, gradually snapping the mounts. Do not immediately try to tear off the lid - this will lead to breakage!
4. When all the latches open, lift the lid at a 45° angle and unplug the fingerprint plume (if any in your modification).

⚠️ Warning: If the lid doesn't lend itself, don't force it! Most likely, the glue is already dry and you'll need a heating method. Trying to "pull out" the lid can damage antenna lines or battery connector.

Method 2: Heated disassembly (for "stiff" covers)

If the smartphone was in use for a long time or was subjected to temperature changes, the glue under the lid could harden, in this case, heating is the only safe way to disassemble. The main rule is not to overheat! The optimal temperature is 50-60 ° C, heating time is 2-3 minutes.

Step-by-step:

• 🔥 Heat the back cover with a hair dryer, keeping it at a distance of 5-7 cm Movements should be circular so that the heat is evenly distributed.
• 🧲 While the lid is warm, apply the suction cup to the top (above the camera) and slightly pull up.
• 🔧 Insert the mediator into the resulting gap and carefully lead it along the edge, snapping the latches.
• 🔌 After removing the cover, immediately disconnect the battery plume (it is under a black protective film).

Critically, don't heat your smartphone for more than 3 minutes in a row! Overheating can damage your battery or melt plastic parts. If the lid doesn't lend itself, let the device cool for 1-2 minutes and repeat the procedure.

What to do after removing the lid: next steps

When the lid is finally removed, the Redmi 6A’s interior design will open up in front of you.

• 📸 Camera module - attached to two screws.
• 🔋 Battery - glued to the body, the train goes to the motherboard.
• 🎤 The speaker and microphone are located at the bottom.
• 📶 Antenna lines – thin metal tracks around the perimeter.

⚠️ Note: If you are disassembling a smartphone to replace a battery, remember that the new battery must be of the same capacity (3000 mAh) and with a similar connector. Using non-original batteries can lead to swelling or fire!

Before you unplug the plumes, take a picture of their location. For example, the display plume in Redmi 6A is attached with a fragile clamp, which is easy to break if pulled in the wrong direction. To detach, gently press the clamp with a plastic blade and pull the plume up.

Common Mistakes and How to Avoid Them

Even experienced craftsmen sometimes make mistakes when disassembling the Redmi 6A. Here are the most common of them and ways to prevent them:

🔹 Broken cap latches. Cause: excessive force in the separation of the body. Solution: Use a thin mediator and heat the lid before disassembling.

🔹 The battery plume was damaged, and the reason was to try to disconnect the plume without removing the protective film, so that you can always carefully remove the black insulation tape above the connector first.

🔹 Lost screws. Reason: no organizer for small parts. Solution: use a magnetic mat or a container with cells.

🔹 The reason is: too long to heat with a hair dryer. Solution: heat in short intervals (30 seconds) with breaks to cool down.

If you do damage a piece, don't panic. Most of the components of the Redmi 6A (battery, camera, speaker) can be ordered separately on AliExpress or in service centers, the main thing is not to turn on your smartphone if you notice a bloated battery or burnt tracks on the board.

💡

The most common mistake in disassembling the Redmi 6A is to try to tear the lid off without first heating or using a mediator, which causes the latches to break 90% of the time.

Build a smartphone: the reverse process

Putting the Redmi 6A back together is usually easier than disassembling, but there are nuances to it.

• 🔌 Connect the plumes in reverse sequence: first the battery, then the display, and then the additional modules (camera, power button).
• 🔧 Twisting screws with moderate effort - pulled mounts can damage the board.
• 🧴 If you use a new glue for the cover, apply it in a thin layer around the perimeter, avoiding the antenna area.
• 📱 Before final assembly, check the performance of all buttons and sensors.

After assembly, turn on the smartphone and test:

1. Quality of communication (call, mobile Internet).
2. Camera and microphone.
3. Charging the battery.
4. Tactile recoil of the buttons.

If something is not working properly, disassemble the device again and check:

- Correct connection of the plumes.

- Integrity of antenna lines.

Absence of foreign objects inside the enclosure (for example, plastic debris).
