Modern smartphones are becoming more difficult to maintain, and the budget Xiaomi Redmi 6A is no exception, despite its affordable cost. Many users face the need to intervene independently in the internal device of the gadget: whether it is replacing a broken screen, installing a new battery or cleaning the speaker from dust. Opening the case is the first and most important step on which the success of all further repairs depends.
In this guide, we will discuss in detail the process of dismantling the back cover, which in this model is not removable, which is often misleading for beginners. You will need not only rubbing, but also the right set of tools to not damage plastic latches and plumes. Redmi 6A has a characteristic design, where access to components is opened only after careful separation of the back panel from the frame.
Before you start physically impacting your device, make sure you are fully aware of the risks. Mistakes can damage the motherboard or impair the tightness of the case. We have prepared a structured instruction to help you minimize these risks and successfully complete the task.
To get started, you’ll need a basic toolkit, which can be purchased from any electronics store or ordered online.Don’t try knives or sharp metal objects, as they can slip and damage the internal components or your finger.
- 🔧 Plastic blade (mediator) for snapping latches.
- 🌡️ Hair dryer or heating platform for softening glue.
- 🧲 Magnetic mat or screw container.
- 📱 Suction cup for careful pulling of the cover.
The quality of the tools directly affects the result: Cheap plastic blades can break at the most inopportune moment, leaving a piece of plastic inside the case, so it is better to use proven kits for repair.
⚠️ Warning: Before starting any work, be sure to turn off the smartphone. Attempting to open the device on can lead to a short circuit and irreversible failure of the electronics.
Preparation of the workplace and heating of the body
The success of the operation depends largely on preparation. The adhesive layer that holds the back cover of the Xiaomi Redmi 6A is very hard and durable at room temperature. If you start pulling the lid without first heating, the plastic can crack and the panel itself can deform.
Use a household dryer by setting the average temperature of the air flow. Do not bring the dryer too close to the surface of the phone so as not to overheat the display matrix or battery. Warm the perimeter of the device evenly for 2-3 minutes, constantly moving the hair dryer in a circle.
💡
Check the temperature of heating with your hand: if the body is hot to hold in your hand, but does not burn, then the temperature is optimal for softening the glue.
Pay special attention to the corners of the case, because it's usually the most glue concentrated, and once heated, the device will feel warm to the touch, signaling that it's ready for the next stage. Take your time, let the heat penetrate into the adhesive layer.
- 🔥 Heat the body evenly from all sides.
- ⏱️ Heating time is from 2 to 4 minutes.
- 🖐️ Check the temperature with your finger so as not to overheat.
Some craftsmen use special heating pads, but the hair dryer is the most affordable and effective tool at home, the main thing is to control the temperature and not make sudden movements with a jerk.
Rear cover separation process
Once the glue is softened, you can start the most delicate step: insert the suction cup into the bottom of the back cover, closer to the edge, and slightly pull up, creating a small gap between the lid and the frame.
Don't try to open the body with one jerk. Your job is to move slowly and progressively along the perimeter of the body. The Redmi 6A has a lot of plastic latches that give off the characteristic click when you snap. Move smoothly, feeling resistance.
☑️ Autopsy action plan
If you feel strong resistance, don't use force. Go back to heating the problem area. Often users break the lid in the area of the camera or volume buttons where the structure is reinforced.
⚠️ Note: Do not enter the instrument deeper 3-4 Inside are plumes and components that are easily damaged by the sharp edge of the shoulder blade when deep dived.
When all the latches around the perimeter are freed, the back cover will be easily removed. Put it in a safe place, preferably on a soft cloth, so as not to scratch the glossy surface, and now you will have access to the insides of the smartphone.
Access to internal components and screws
When you take the back panel off, you'll see that most of the interior nodes are covered with a black plastic cover that protects the motherboard and battery. This cover is also attached to screws and latches. The Xiaomi Redmi 6A uses a standard small cross screwdriver.
Carefully inspect the perimeter of the protective cover. The screws can be hidden under decorative stickers or have different sizes, it is recommended to lay the screws in the order in which you twist them, or use a magnetic mat with markings.
| Component | Type of attachment | Location. | Features |
|---|---|---|---|
| Back cover. | Glue + latches | Perimeter. | It requires heating. |
| Protective plate. | Screws (cross) | Center of the hull | Different sizes of screws |
| Battery | Adhesive tape | The bottom part | Eat through the tongue |
| Maternity fee | Screws + plumes | Upper part | Careful with the plumes. |
After you unscrew all the visible screws, don't rush to remove the protection, swipe the perimeter to snap the plastic locks, and then you can gently lift the plastic lining.
Hidden screws.
Under the cover, you'll find connectors connecting the battery, the display and the control boards, and you're now ready for further manipulation, whether it's a battery replacement or a cleaning.
Work with battery and plumes
The first thing to do after removing the protection is to turn off the battery, which is a critical safety step, so find the battery connector that goes to the motherboard and gently disconnect it with a plastic blade.
The Redmi 6A has a battery that is glued to the body with double-sided tape. Don't try to pick it out with a screwdriver - this can cause puncture and fire. Use special screeds or just heat the case again to loosen the glue, and pull on special tongues if you have any.
- 🔋 Turn off the battery plume first.
- 🌡️ Heat the lower part of the body for unsticking the battery.
- 🚫 Do not pierce or bend the battery.
- 🧹 Clean the seat from old glue.
When you're working with the display and touchscreen plumes, be very careful. They're very thin and easily torn. If you're planning to replace the screen, disconnect all the visible connectors from the board.
⚠️ Attention: Lithium polymer batteries are sensitive to mechanical damage and a damaged or bloated battery must be disposed of at special reception points.
Once all components are turned off, the motherboard can be fully removed if repairs require it, usually held on multiple screws and carefully removed after all connections are released.
Device assembly and inspection
You do the reverse assembly. You install a new battery or a refurbished module, you plug all the plumes in until you click right away. Make sure the connectors are flat and tight.
Before the final sticker on the back cover, it is recommended to run a test run. Connect the battery and press the power button. If the smartphone is turned on and the image on the screen appears correctly, you can proceed to the final assembly.
💡
Always test the run before the final gluing of the case to avoid re-disassembly in case of error.
Apply a new layer of glue (B-7000 or special glue for electronics) to the frame of the case. Spread it evenly in a thin layer and press the back cover. Lock the device with rubber bands for 15-20 minutes before drying.
Twisting all the screws of the protective plate, keeping order. Don't pull the screws over so as not to break the thread in the plastic racks of the case. Xiaomi Redmi 6A is ready for use again.
