Xiaomi Redmi 6A is one of the brandβs most popular budget smartphones, released in 2018. Despite its simplicity of design, its disassembly requires accuracy and knowledge of key points, from the right tool selection to the sequence of removal of mounts. This article will help avoid the typical errors that lead to damage to the plumes, display or battery.
The Redmi 6A may need to be disassembled for a variety of reasons: battery replacement, dust cleaning, speaker or camera repair. However, it is important to understand that self-disassembly is insecure (if it is still valid) and fraught with risks. For example, damage to the flexible display plume is the most common problem when you carelessly remove the front panel. We will examine each step in detail, paying attention to the pitfalls.
Preparation for disassembly: tools and security measures
Before you start, make sure you have everything you need. The Redmi 6A is built on latches and screws, so you can't do without specialized tools. Here's the minimum set:
- π§ Plastic blade (or mediator) - to separate the body without scratches.
- βοΈ Screwdriver cross (PH00) β back-cover.
- π Suction - will help to tamper with the display (optional, but simplifies the process).
- π§² Magnetic mat or container β to avoid losing small details.
- πΈ Smartphone for photography - fix the location of plumes and screws.
Also, prepare your workspace: a clean, well-lit surface without carpets (screws are easily lost in the pile). If you're taking your phone apart for the first time, watch YouTube videos -- visuals will help you avoid mistakes. And remember, the Redmi 6A battery is soldered to the motherboard -- it requires a soldering iron or special equipment to replace it.
β οΈ Warning: If the phone has been in water or has been hit, disassembly may result in a short circuit.
Removing the back cover: how not to break the latches
Redmi back cover 6A It's mounted on latches and two screws under plugs. Start by turning off the phone and retrieving it. SIM-cards and microSD (if installed:
- Find the two screws at the bottom of the lid (near the microUSB connector) hidden under the stickers β gently tuck them in with a nail or a plastic spatula.
- Take the screws out and put them aside (they are of different lengths - do not confuse!).
- Insert the plastic blade into the gap between the lid and the body (start with the lower right corner) and carefully guide it around the perimeter, snapping the mounts.
The lid should be removed effortlessly. If it doesn't give in, don't push harder -- you've probably missed the latch. Check if all the screws are twisted and try again. Don't use metal tools, they leave scratches and can damage the plastic.

If the latches are too tight, slightly heat the cover with a hairdryer (not higher than 60 Β° C) - the plastic will become softer, and it will be removed easier.
| Phase | Tool. | Possible errors |
|---|---|---|
| Removal of stickers | Nail/scapula | Damage to the sticker (uncritical) |
| Screwing of screws | Screwdriver PH00 | Removing the slime (use a quality tool) |
| Cover compartment | Plastic spatula | Breaking the latch (move slowly) |
Battery Disconnection: Why Itβs Important to Do It First
When you take the lid off, you'll see the battery covered in black film, and the first rule of disassembling any smartphone is to turn off the power to avoid short circuits. In the Redmi 6A, the battery is soldered to the board, but you can temporarily disconnect it:
- Tap the battery plume carefully (it is under the film, closer to the top of the phone).
- Use a plastic spatula to lift the connector. Don't pull the wires!
- Secure the plume with tape in the disconnected position so that it does not touch the contacts.
If you're planning to replace your battery, consider this: it will require a soldering station and experience with microelectronics, and at home, it's best to limit yourself to cleaning contacts or diagnostics without completely removing the battery.
β οΈ Warning: If the battery is swelling (as seen from the deformation of the lid), do not attempt to pierce or bend it. This can lead to fire.

Motherboard removal: the procedure for disconnecting plumes
The Redmi 6A motherboard is mounted on multiple screws and connected to the display, camera, speaker and buttons via plumes to extract it:
- Unscrew all the screws around the perimeter of the board (there are about 10 pieces, of different lengths - remember where it was!).
- Disconnect the plumes in that order: π± Display plume (the widest, at the top). π· Main camera plume (thin, next to battery). π Dynamic plume (small, at the bottom of the). π The loop of the on/volume button (under the metal screen).
Carefully tuck the board with a plastic spatula and raise it at an angle of 45Β°. Don't pull vertically - you can damage the contacts!
If the board doesn't want to come out, check if all the screws are twisted. Sometimes there are additional mounts under it (for example, under stickers), also pay attention to the metal screen above the processor - it must be removed separately, twisting 2 screws.

Display module disassembly: when necessary
The Redmi 6A is glued to the frame with double-sided tape, and you'll need a hair dryer or heat gun to remove it, and a suction cup, and it looks like this:
- Heat the edges of the display with a hairdryer (temperature ~50-60Β°C) for 1-2 minutes.
- Suction stick to the bottom of the screen and pull up. If the display doesn't respond, repeat the heat.
- After separation of the edge, insert a plastic spatula and carefully lead it around the perimeter, cutting the glue.
Do not use wet wipes or aggressive solvents for cleaning, they can damage plastic parts. If you find corrosion on the board, it can be carefully removed with a toothbrush with isopropyl alcohol (concentration is not lower than 90%).
After cleaning, allow the parts to dry completely (at least 30 minutes) before assembly.This will prevent short circuits when switched on.
Phone Assembly: Reverse Sequence and Testing
To assemble Redmi 6A need in reverse order, but taking into account a few nuances:
- Make sure all the plumes are tightly connected (they should snap with a slight click).
- Screw the screws cross-curl to avoid skewing the board.
- Before final assembly, turn on the phone with the battery connected (but without the cover) to check the performance.
If the phone does not turn on after assembly, check:
- π Is the battery connected (sometimes the plume falls out when vibrating).
- π§ Are the screws not pulled (this can cause the circuit board to close on the body).
- π± Is the display properly connected (if the screen doesn't light up, but the phone vibrates when turned on).
If everything works, seal the screws on the back cover with new stickers (they are sold in repair kits) to protect them from dust and moisture.
β οΈ Warning: After assembly, check all the sensors: gyroscope, compass, proximity sensor. If they're not working properly, you probably forgot to plug in the plume or damaged the contacts.
