Modern smartphones, despite their reliability, often require structural intervention. The Redmi 6A is no exception: the budget cost of the device often involves the use of materials that wear out over time. Replacing broken glass, battery or speaker is a procedure that many users prefer to perform on their own to save on the services of service centers. However, in order not to turn a minor repair into a complete replacement for the gadget, it is important to clearly understand the algorithm of actions.
The Xiaomi Redmi 6A disassembly process has its own peculiarities related to the design of the body and the location of the plumes. Unlike the flagship models, there is no moisture protection and complex screw system, but there are fragile plastic latches that require caution. In this article, we will take a detailed look at each stage of dismantling, paying special attention to the safety of components and the proper use of tools.
Before you start, you need to prepare the workspace, it needs to be well lit and the surface is clean and non-magnetic, so as not to lose small details. Redmi 6A uses a combined housing, where the back cover is part of the frame, which makes it easier to access the insides, but requires accuracy when opening. Take your time: every movement must be adjusted, because the cost of error can increase in the cost of a new display module.
Tools and workplace preparation required
Quality training is half the success. To disassemble the Redmi 6A, you'll need a minimal toolkit, which can be found in any specialty store or ordered online. Using inappropriate items like scissors or kitchen knives can cause damage to the body or, worse, injury to the hands.
The main tool will be a suction cup to lift the back cover. Since the lid in this model is plastic and is attached to the latches around the perimeter, a sharp jerk can break the mounts. Also an indispensable assistant will be a mediator or a plastic blade to snap clips. Metal tools are not recommended, as they are easy to damage the internal plumes or break the battery.
You'll need a set of screwdrivers to work with screws. The Xiaomi Redmi 6A uses asterisk screws like Torx, so a standard cross screwdriver won't work here, and you'll also need tweezers with curved ends to extract small parts and plastic plugs.
Here is a list of what you should have on hand before starting the procedure:
- 🔧 Sets of screwdrivers (required to have a Torx bit) T5 or T6).
- 📱 Plastic suction cup or smartphone opener.
- 🛠 Plastic mediator or spatula (spudger).
- 🧲 Magnetic mat or screw sorting container.
In the case of non-shallable smartphones, this means turning off the battery plume immediately after the first lid is removed.
⚠️ Warning: Never use metal blades to jack up the lid next to the battery.Puncture of a lithium-ion battery will cause instant fire or explosion.
Primary dismantling and removal of the back cover
So we start the immediate disassembly process. The Redmi 6A has a removable back cover, but it's not just a hand-held back cover, like in old phones with removable batteries, and it's a system of hidden latches all around the perimeter of the device, and your job is to evenly distribute the force to snap them off without breaking the plastic.
First, make sure the tray is SIM-If you try to open the lid with the tray installed, you can damage the locking mechanism or the tray itself. Once you remove the card, take the suction cup and attach it to the bottom of the back cover, closer to the center, but avoiding the camera area.
Make a slight tension with the suction cup upwards to create a microscopic gap between the lid and the frame. Insert a plastic mediator into this gap carefully. Don't try to push the body straight away -- your goal is to free one latch to access the rest.
Move the mediator along the edges, sliding through an imaginary glue line or snapping clips. Pay special attention to corners where the plastic is often thicker and stronger. Once all the latches around the perimeter have been passed, the lid will easily be removed.
☑️ Check before removing the lid
Once the lid is removed, you will have access to the main board, battery and connectors. At this stage, it is important not to make sudden movements, since some models may have a fingerprint scanner plume connected to the lid, although in the 6A it is usually located on the main board.
Disconnection of the battery and removal of the protective plate
Once the back cover is removed, the first thing you see is a black plastic panel covering the main board and the top of the battery, and it's a protective shield that also serves as a radiator and a lock of the plumes, and to access the internal components, it has to be dismantled.
The panel is secured by multiple screws. In the Xiaomi Redmi 6A, the number of screws can vary, but it's usually 10-12 screws around the perimeter and in the center. They all have the same size and type of slit (star).
After you've twisted all the screws, don't rush off the plate, there may be antenna contacts underneath, and then you can gently lift the plate with a pint or a mediator, and check if there are plumes underneath, and in this model, the plumes usually go under the plate, but they don't attach directly to it.
The most critical thing is to turn off the battery. Find the battery connector on the motherboard. It's on the top, under the protective plate. Carefully tuck the connector into a plastic blade or nail as you move parallel to the board. Never pull the plume up behind the wires, which can cause the contacts to break.
After the battery is turned off, the device is completely de-energized, and you can safely continue to work without fear of short circuits when the contacts are accidentally touched by the tool.
Why turn off the battery first?
Dismantling of the main board and auxiliary modules
Now that the power is off, you can start removing the main board, which is mounted by screws and is held by the dynamic speaker and vibrator contacts, and you first need to release all the plumes that go to the board.
Carefully disconnect the plumes of the main and front camera modules, as well as the display plume, which can be pressed with metal locks. If you have a lock, you need to bend it up first. The plumes are very thin and fragile, so you need to pull them strictly by the thickened connector, not by the flexible part itself.
At the bottom of the board are the contacts that dock with the bottom board (sub-board) where the charging connector is located. Often the board is simply removed up after unscrewing all the screws. However, in the Redmi 6A, the design may require the removal of some elements beforehand.
And you can see the audio speaker module and the front camera module, and some versions can be integrated into the screen, some can be mounted onto the frame, and if they're on the frame, they need to be carefully removed with tweezers after the board is removed.
The table below will help you navigate the sequence of actions when working with components:
| Component | Location. | Type of attachment | Features |
|---|---|---|---|
| Basic fee | Upper part | Screws + grooves | Lots of small plumes |
| Battery | Centre/Near | Glue + connector | Requires heating to remove |
| Lower fees | Bottom of the hull | Screws. | Contacts of dynamic dynamics |
| Vibromotor | Lower corner | Glue/Getting | Small size. |
When removing the board, try to keep it by the edges, avoiding touching chips and contacts with your fingers. Fat marks can oxidize over time.
Replacement of the display module and work with the frame
If your goal was to replace the screen, the process is a little different. In the Xiaomi Redmi 6A, the display module is often sold with the frame. This makes it much easier: you don't have to separate the glass from the frame, which requires special equipment.
To replace, you will need to transfer all components from the old frame to the new one.This includes: the main board, the charging lower board, the battery, the vibrator, the auditory speaker and the side buttons (volume and on).
The side buttons are small parts that are easy to lose. They are plastic or metal slats that transmit the pressing of the microswitches on the board. When you move, make sure they stand in their grooves and don't hang around.
The battery in older devices is often held on double-sided tape. To remove it without damage, the body needs to be slightly warmed up (for example, with a hairdryer or on a warm mat) to a temperature of 40-50 degrees. The glue will become softer, and the battery can be removed by putting a plastic card on it.
When you install a new module with a frame, first fix the battery and the bottom board, then install the main board and connect all the plumes. Only after checking all the connections can you screw the protective plates.
⚠️ Note: When moving volume buttons, make sure that rubber or plastic pushers are not lost. Without them, the buttons on the body will be pressed idly without turning the sound on or off.
Device assembly and initial start
The assembly is done in reverse order, but requires even more care, and the main task is to properly fit all the plumes into your channels so that they are not clamped with a frame or screws. A compressed display plume can lead to stripes on the screen or complete absence of the image.
Start by installing the bottom board and battery. Make sure the charging connector matches the hole in the case. Then gently stack the main board, hitting the screws into the holes. Twisting the screws without undue effort to avoid breaking the thread in the plastic.
Plug the battery plume last before installing the protective plate. After connecting the plate, check if all screws are twisted. Then put on the back cover starting on one side and press the perimeter until the characteristic snap of the latches.
Now you can turn on the device. If the screen catches fire, the image comes up, and the touchscreen goes on, you've done it. Check the cameras, the speaker, the microphone, the vibrating response.
💡
If the phone doesn't turn on after assembly, don't panic. Often the problem is a poorly inserted plume of the display or battery. Disassemble the device again and reconnect all the connectors, making sure they snap to the end.
If the phone turns on but doesn't respond to touch, check the touchscreen plume, and sometimes you need to remove the protective film from the new screen if it's still on the inside.
💡
Good assembly is not just about screws that are twisted, but also about plumes that are properly stacked, and any inflection or clamping can cause a failure after a week of use.
