Xiaomi’s smartphones, including the Redmi 6A budget line, are known for their affordable price tag and robust design, but even they are not immune to mechanical damage or failure of internal components. Disassembly of the device may be required to replace a broken display, worn-out battery or, if necessary, deep cleaning of dust and moisture. Understanding the architecture of the case and the sequence of actions is critical to successfully complete the procedure without damaging the surviving parts.
The Redmi 6A's dismantling process has its own features, such as the plastic body and the arrangement of plume joints. Unlike more expensive models, it uses standard screws and latches, but requires careful handling of fragile components.
Despite the apparent simplicity of the design, rushing can damage the touchscreen plume or cracks in the back cover. In this article, we will take a closer look at each stage of disassembly, paying attention to the nuances that are often forgotten by beginners. Safety and attention to detail ensure the safety of your device.
Tools and workplace preparation required
To properly and safely disassemble the Xiaomi Redmi 6A smartphone, you will need a minimum set of tools that can be found in any radio store or ordered online. Using inappropriate items such as kitchen knives or thick needles can lead to irreversible damage to the body and internal boards. The main tool for working with screws will be a small cross screwdriver, usually marked as PH0 or PH00.
A plastic mediator blade or special opening tool is ideal for opening the case and snapping plastic latches. Metal tools should be used with extreme caution to avoid damaging the battery or closing contacts on the motherboard. You will also need a suction cup to neatly tear off the back cover if it is planted on glue, although this model is dominated by latches.
Be sure to prepare a container for sorting screws, as they can vary in length and thread. Mixed screws can damage the internal components when assembled. It is also recommended to use tweezers with curved ends to work with small plumes.
- 🛠️ Screwdriver cross PH0/PH00 hull-screw.
- 📱 Plastic blade (mediator) for opening the body without scratches.
- 🔍 Tweezers with dielectric coating for working with plumes.
- 🧲 Magnetic mat or organizer for sorting screws of different sizes.
Organizing space is key to success. Make sure there are no extra items on the table that can fall inside your smartphone or get lost. Good lighting will allow you to see the fine details and markings of the connectors.
⚠️ Warning: Before starting any work, be sure to turn off your smartphone. Working with the device on can short-circuit and failure of the motherboard.
Rear cover removal and primary access
The Redmi 6A has a non-removable back cover that is attached to the perimeter on plastic latches. Unlike older models, there are no screws hidden under plugs, which simplifies the initial stage. The process begins with the careful insertion of a thin tool into the gap between the frame and the rear panel.
Insert a plastic blade or thin metal scalpel (with caution) into the bottom of the device, next to the charging connector. Smoothly drive the tool along the side faces, hearing the characteristic clicks of the opening latches of the case. Do not try to open the lid from one edge - this will lead to breakage of the plastic.
Move around in a circle, gradually snapping the locks. Pay special attention to the areas around the camera and speakers where the latches can sit tighter. After passing the entire perimeter, the cover should be easily removed.
- 🔓 Start the autopsy at the bottom end of the device where it is located. USB-port.
- 🔄 Move along the long sides of the body, evenly freeing the latches.
- 🚫 Avoid sharp jerks so as not to break plastic fixtures.
Once the lid is removed, you will have access to the internal components, and immediately notice the state of the battery and the presence of traces of moisture or corrosion.
💡
If the back cover is glued and does not open with a shoulder blade, carefully warm the perimeter of the body with a hairdryer at a temperature not higher than 80 ° C for 1-2 minutes. This will soften the glue and facilitate opening.
Disconnecting the battery and removing protective screens
The first step after the back cover is to de-energize the device, which is a critical step for the safety of further manipulation, so find the battery connector on the motherboard and gently disconnect it by putting a plastic blade on the connector.
Then you remove the metal plate that covers the main display and touchscreen connectors, and it's mounted with a few screws that you need to unscrew and put into a prepared container, and there are plumes underneath that need to be handled carefully.
Use tweezers or a spatula to turn off the plumes. Move from bottom up or top down without putting too much effort. The plumes in Redmi 6A are thin enough to break when handled carelessly.
- 🔋 First, disconnect the battery connector from the motherboard.
- 🔩 Unscrew all screws holding the metal protective plate.
- 📉 Carefully click the plumes of the display and touch screen, lifting them up.
⚠️ Warning: Never pull the plume itself. Only work on the hard connector, otherwise the current tracks will be damaged and the display will stop working.
Once all connections are disconnected, you can proceed to retrieve the main components, and make sure that no cables are stuck under the frame or other parts.
☑️ Safe shutdown
Extracting motherboard and essential components
Once all the plumes are turned off, the Xiaomi Redmi 6A motherboard becomes free, but can be held by screws around the perimeter or under the speaker. Carefully inspect the board for hidden fasteners. Often a single screw can hide under a sticker or in the corner of the case.
Carefully raise the charge to check if antenna contacts or other small connections are still connected. The main module is removed by moving upwards and slightly away from the connectors. Put the charge on an antistatic mat or a clean surface.
The board is usually removed and the top of the antenna, if it is not attached separately, and if you need to replace the charging connector or microphone, these components are often soldered on the lower board or connected by a plume to the main one.
| Component | Location. | Type of attachment | Features |
|---|---|---|---|
| Maternity fee | Upper part | Screws + latches | Requires a shutdown of 3-4 plumes |
| Battery | Central part | Adhesive tape | Hard to get out without heating. |
| Lower fees | Bottom of the hull | Screws. | Contains a charging connector |
| Dynamician | Lower corner | Screws + contact | It has a rubber sealer. |
When working with the motherboard, avoid touching the contacts with your fingers, as fat and sweat can cause oxidation. If you plan to replace the board, make sure the new version is compatible with your model.
How to check the integrity of the fee?
Replacement of the battery and work with the glue layer
In the Redmi 6A, the battery is glued to a plastic body with double-sided tape, a standard practice for modern smartphones, providing a tight fit but complicating replacement. Attempting to pull the battery out by force can damage and ignite it.
Use a dryer by warming up the back of the case (if the lid is removed) or directly the battery area through the open space. The temperature should not exceed 60-70 degrees so as not to damage the plastic cells.
Use a plastic card or a special blade to gently cut the glue under the battery. Move the tool parallel to the plane of the battery. Do not use metal objects that can puncture a lithium polymer cell.
- 🌡️ Warm up the battery area with a hairdryer during 2-3 minute.
- 💳 Tap the edge of the battery with a plastic card and slowly lead along the glue.
- 🧹 Clean the remnants of old glue before installing a new battery.
The new battery should also be fixed. Use a special glue B-7000 or double-sided tape for the batteries. Do not pour glue inside, just apply it around the perimeter or cross.
⚠️ Warning: If the battery is swelling, do not puncture it or bend it. Remove it with utmost care, using only plastic tools.
💡
Safe recovery of the battery is possible only after preheating the adhesive layer.Cold battery can crack or damage the housing when removed.
Assembly of the device and verification of functionality
The Xiaomi Redmi 6A is assembled in reverse order. Set the battery up, make sure it fits tightly. Connect the battery plume to the motherboard, but don't lock the board with screws just yet.
Turn on your smartphone by pressing the power button. If the device is on and shows the image, that's a great sign. Check the touchscreen, the speakers, the microphone and the vibration. Make sure the smartphone sees. SIM-map and Wi-Fi network.
If all the tests are successful, turn off the phone and continue building. Set a metal plate and twist all the screws. Close the case with the back cover, evenly pressing the perimeter until the latches click.
- 🔌 Connect the battery and turn on the phone for initial check.
- 📱 Test the sensor, sound and communication modules before final assembly.
- 🔩 Twisting all the screws of the protective plate and fix the cover.
Don’t ignore the pre-inspection phase: assembling a device with a faulty component will require re-disassembly, which increases the risk of damage.
Frequent errors in disassembly and their consequences
Inexperienced craftsmen often make mistakes that can cost a device life. One of the most common is the use of excessive force when breaking a lid or plumes. Redmi 6A plastic is fragile, and one wrong move can lead to cracks.
Another mistake is losing or entanglement of screws, long screws screwed into short holes can break through the board or the body, and always sort the fastener as you disassemble it.
Ignoring battery shutdown is a fatal mistake. Accidental closure of contacts with a tool can burn the power controller or other important nodes. Always work with a powered device that is powered down.
- ❌ Application of metal tools for picking inside the body.
- ❌ Ignoring heating when removing the battery.
- ❌ Assembly without prior performance check.
Be careful and use the right tools minimizes the risks, and if you're not confident, you should consult a professional.
