Disassembly of the Xiaomi Redmi 6A smartphone can be required for various reasons, ranging from a banal battery replacement to a complex repair of the motherboard.This budget device, despite its availability, has a fairly dense layout, which requires the wizard to be attentive and accurate. Incorrect opening of the case often leads to damage to plumes or cracks in the glass, so it is important to strictly follow proven algorithms of actions.
Unlike modern flagships with waterproofing, the Redmi 6A is relatively simple, but there are some nuances: the back cover is made of plastic, which makes it easier to dismantle, but the adhesive layer can be quite aggressive. Before starting any work, make sure you have all the necessary tools and the workplace. In this model, the fingerprint scanner plume is glued to the body, and its damage is the most common mistake of beginners when the cover is not neatly raised.
The disassembly process requires patience. You don't need the skills of a professional engineer to perform basic manipulations like changing the battery or cleaning the charging connector. The main thing is to understand the sequence of actions and knowing the location of the hidden screws. In this article, we will look at each step in detail so that you can safely open your gadget.
Preparation of the workplace and necessary tools
Quality preparation is the key to successful repairs. To work with the Xiaomi Redmi 6A, you will need a specific set of tools that will avoid scratches and chips. Do not try to use kitchen knives or thick screwdrivers, as they can damage the plastic of the case or shielding plates.
First of all, make sure you have a good light source: small screws and thin plumes are poorly distinguishable in dim lighting, which increases the risk of error. It is also recommended to use an antistatic mat or just a clean, dry table surface covered with white cloth, so as not to lose fine details.
To remove, you will need the following tools:
- ๐ง Precision screwdrivers (cross-haired) PH000 and PH00)
- ๐น Plastic mediators or shoulder blades for opening the body
- ๐ฅ dryer or warmer
- ๐งฒ Magnetic mat or organizer for screws
- ๐งค Thin tweezers (preferably dielectric)
Special attention should be paid to heating. The glue holding the back cover is very hard at room temperature. Heating the case to 60-70 degrees Celsius will greatly simplify the process of separating the plastic from the frame. Use the dryer evenly, driving the air jet around the perimeter so that the battery or the display matrix does not overheat locally.

Dismantling the back cover of the smartphone
The first step in the process of opening Xiaomi Redmi 6A, is a withdrawal SIM-This is a mandatory procedure, because trying to tamper with the card mounted can damage the contact group or the tray itself.
After removing the tray, you need to warm up the perimeter of the back panel. Pay special attention to the corners, since there the glue freezes most tightly. Be careful in the area of the camera: excessive heating of the lens can cause fogging of the lenses from the inside or damage the optical stabilizer, if it is present in your modification.
When the body is sufficiently warmed, insert a thin mediator into the junction between the back cover and the frame. It is best to start from the bottom or side, away from the plume of the fingerprint scanner. Carefully guide the instrument along the perimeter, listening to the clicks of the detachable glue. Don't dip the mediator too deep so as not to touch the internal components.
โ ๏ธ Attention: At the top of the body, next to the camera lens, a fingerprint scanner plume passes. When lifting the lid, be extremely careful not to break this thin conductor.
Once all the latches are snapped, don't rush to pull the lid up abruptly. Smoothly lift the edge and check if there are any glued areas left. If the lid is difficult to put in, it's better to add a little more heat than to use physical force. Redmi 6A plastic is flexible, but when a sharp jerk can burst in the places where the screws are attached.
Disabling the plumes and removing the protective plate
After successfully removing the back cover, you will see the interior of the smartphone, the main motherboard, the metal plate, the battery and the main camera module, and at this point, it is important not to touch the plume contacts and the camera lenses with your fingers.
The first thing you need to do is turn off the battery, which is a critical safety step, so find the battery connector, which is usually located at the bottom or middle of the board, and gently disconnect it with a plastic blade, and only after it's turned off can you continue to work with other components.
Next, unscrew the screws that fix the metal plate over the boards. In Xiaomi Redmi 6A, their number can vary, but usually there are about 10-12 pieces. They can be of different lengths, so it is recommended to lay them out in the same order in which you twisted them, or use a magnetic mat with markings.
After removing the plate, access to the main plumes will open:
- ๐ฑ Display plume (the widest connector)
- ๐ Battery plume (already disabled)
- ๐ธ Main and front camera plumes
- ๐ Lower plume (charging, microphone, speaker)
- ๐ Side button plume and fingerprint scanner
Turn off the plumes by putting their connectors upwards, rather than pulling the wires themselves. FPC (Flexible Printed Circuit) connectors are very fragile. If the connector has a locking latch, it must be bent beforehand. In Redmi 6A, most connectors are fixed by a tight fit without additional locks, but require accuracy.
Nuances of connector work
Extraction of motherboard and modules
Now that all the connections are broken, you can start removing the motherboard, which is held on perimeter screws and possibly on additional mounts in the center. Carefully examine the fee: sometimes one screw can be hidden under a sticker or warranty seal (although in public sector seals are rare).
Pay attention to the antenna contact. Often, the pogo pin can get stuck in the back of the board or on the back, and if you pull the board abruptly, the contact can bend or break away, causing the network to receive a poor reception.
When retrieving the board, also keep an eye out for the fingerprint scanner plume. Even if you've unplugged it from the board, it can be glued to a frame or battery. Free it up by gently peeling off the two-way scotch. Xiaomi Redmi 6A has a scanner built into the back cover, so the plume goes from lid to board.
The main components that are now available for replacement:
- ๐ Battery battery (replacement when bloated or worn out)
- ๐ Lower board with charging connector (frequent breakdown)
- ๐ Polyphonic speaker and conversational speaker
- ๐ท Modules of the main and front cameras
- ๐ Vibromotor and button plumes
The Redmi 6A battery replacement often requires heating, as it is glued to a plastic frame with two strips of scotch. Use a suction cup or special tape to pull the battery out, preheating the back of it. Don't pierce the battery with a screwdriver!

If the bottom board is sitting tight, don't pull it at the charging plug. Unscrew all the visible screws and see if it's holding onto the glue. Forge the board on the opposite side of the connector.
Table of main characteristics and compatible modules
When ordering parts for Xiaomi Redmi 6A, it is important to know the exact model of your device, as externally identical smartphones can have different internal components.
| Component | Description / Model | Features of compatibility |
|---|---|---|
| Display module | IPS LCD, 5.45 inches | Compatible with Redmi 6A (M1803E6M) |
| Battery | BN46, 3,000 mAh | Universal for Redmi 6A, check the connector |
| Back cover. | Plastic, with a cutout under the scanner | It is important to have a hole under the fingerprint scanner |
| Lower plume | Micro-USB, microphone, speaker | Check the location of the screw holes |
Using non-original displays can cause the sensor to malfunction or brightness will be lower than stated. Xiaomi original matrixes have high-quality color reproduction and oleophobic coating. When buying, pay attention to the presence of a frame: modules can be sold with and without a frame.
If you change the bottom board (charging connector), make sure the version of the board matches yours. The differences may be in the location of the microphone or speaker mounts. Visually compare the new board to the old one before installing.
Assembly of the device and check of performance
The Xiaomi Redmi 6A is built in reverse order, but requires even more care. The main task at this stage is to properly stack all the plumes and not confuse the screws. Start by installing the motherboard and connecting the display plume.
Before you finally roll all the screws and stick the lid, you need to do a primary check. Connect the battery and press the power button. If your smartphone is on, check the touchscreen, sound, vibration and cameras, and this will save you time in case you forgot to plug in some plume.
Once you're sure you're working, turn off the battery again and continue building. Set a metal shield and twist all the screws. Then glue the body perimeter with new B-7000 glue or use double-sided tape to securely lock the back cover.
โ ๏ธ Warning: Do not turn on your smartphone immediately after the lid is glued if you have used liquid glue. 1-2 hours, otherwise the adhesive pairs may settle on cameras or display.
The final stage will be the installation SIM-Check if the phone sees the network, whether Wi-Fi and Bluetooth are working, if all functions are working properly, the assembly can be considered complete.

Quality assembly depends on the cleanliness of the contacts and the correct stacking of the plumes. Do not allow wires to break when installing the cover.
