Modern low-end smartphones like the Xiaomi Redmi 6A often require hardware interventions for a variety of reasons: it can be replacing a broken display, installing a new battery, or cleaning the speaker from dust. Self-repair saves a significant amount of money if you approach the matter wisely and accurately.
The process of disassembling this device has its own peculiarities related to the design of the body and the location of the internal components. Unlike the flagship models, there is no moisture protection, but there are plastic latches that require careful handling, the correct sequence of actions will avoid damage to the plumes and breakage of plastic mounts.
Before you start, you need to make sure you have the basic tools and the right workplace. Good lighting and no static electricity are key to a successful operation. In this article, we will take a detailed look at each stage of dismantling so you can safely reach the internal nodes of the gadget.
Tools and workplace preparation required
Quality repair preparation is half the success. To disassemble the Redmi 6A, you'll need a minimal but specific toolkit, which can be purchased from any radio parts store or ordered online. Using inappropriate items like knives or thick needles can result in scratches on the body or damage to internal boards.
First of all, get a set of screwdrivers, which necessarily include the bits Phillips #00 and Phillips #000, which are used to twist the screws of the motherboard and speaker, and also critically important plastic blade (mediator) to open the case without damaging the plastic.
💡
Use a magnetic mat or spread the screws in the order of their twisting - this will help not to confuse the fasteners of different lengths during assembly.
Additionally, prepare tweezers with curved ends for working with small plumes and a suction cup for neatly unsticking the back cover. It is not superfluous to have a thermophen or a construction hair dryer if the back panel is glued too strongly, although this model is dominated by latches.

- 🪓 Plastic blade or mediator for opening
- 🧲 Tweezers with antistatic coating
- 🌡️ Suction and hair dryer (optional for softening glue)
Primary actions and removal of the back cover
Start disassembling Xiaomi Redmi 6A This is a basic safety rule, and ignoring it can short circuit the board. SIM-cards and memory cards so as not to damage them in the process of work.
The back cover of the smartphone is fixed around the perimeter with plastic latches and perhaps a small amount of glue. To remove it, carefully insert a plastic blade into the gap between the frame and the lid at the bottom of the case, closer to the charging connector. Do not use metal tools, as they can split the plastic.
⚠️ Note: Do not try to cover the corners of the device immediately - there are plumes and antennas that are easily damaged if you carelessly move.
Swipe the blade along the side faces, sequentially snapping the locks. Move slowly, feeling the resistance of the plastic. When all the latches are released, the lid will easily be removed. If it is held tight, you can slightly warm the perimeter with a hairdryer at a temperature of 80 degrees.
Dismantling of protection elements and battery
When you take the back off, you'll see an interior space that's covered by a plastic frame that's mounted with a number of screws of different sizes that you need to unscrew, and you'll be careful that the screws can be hidden under stickers or placed in recesses.
The next critical step is to turn off the battery, and the battery plume will fit the motherboard either on the bottom or side, depending on the board revision, and then you can carefully tuck the connector into a plastic blade, so you can keep the plug on the board intact, and then you can continue disassembling.
To extract the battery itself, the Redmi 6A often has a special exhaust belt (tongue) in it, if it is not available, gently shovel the battery on the opposite side of the plume, and do not compress or puncture the lithium polymer battery, which can cause fire.
- 🔋 Turn off the battery plume first thing
- 🔩 Unscrew all visible screws of plastic frame
- 🧩 Carefully remove the battery using the exhaust tongue
☑️ Safe operation with the battery
Removal of motherboard and modules
The motherboard in Xiaomi Redmi 6A is located at the top of the case and is closed with a metal screen or additional plastic protection. To access the main connectors, you need to remove the upper plastic bar, which is also held on screws and latches.
Notice the plumes that go to the main board: the display connector, the button plume, the lower board plume and the cameras. Each of them has its own lock lock, and before removing the plume, you need to bend or move the lock, if it is designed.
Once you've shut down all communications, unscrew the screws that hold the board itself, which are usually few, but they can be of different lengths, remember or photograph the location of each screw, and the board should be pulled out with tweezers, grabbing the edges without touching the contacts.
Nuances of plume work
The main camera module deserves special attention, it can be mounted with a screw or simply inserted into the connector, and when you remove the camera, hold it by the metal body, avoiding touching the lens with your fingers, since the greasy spots will be difficult to remove.
Disassembly of the lower part and replacement of speakers
The bottom of the smartphone contains a polyphonic speaker, a vibrator and a charging board with a microphone. The speaker in the Redmi 6A is often combined with a plastic case and glued with double-sided tape. It requires careful peeling off to replace it.
The sub-board connects to the motherboard with a wide plume that runs along the side face, often covered by plastic rails, and when assembled, it is important to properly stow this plume so that it does not rub against the body.
The vibromotor is usually located next to the speaker or on the charger board, it is connected by a separate contact connector or soldered, and if the vibration is lost, check the contact first, and then change the motor itself.
| Component | Type of attachment | Difficulty replacing | Risks. |
|---|---|---|---|
| Battery | Glue/Language | Low. | Puncture fire |
| Display module | Glue/Frame | Tall. | Breaking glass, plume |
| Maternity fee | Screws/Steams | Medium | Damage to connectors |
| Polyphonic Dynamics | Glue/Spins | Low. | Loss of leakage |
⚠️ Warning: When installing a new speaker, make sure that the speaker mesh matches the hole in the body, otherwise the sound will be quiet and hoarse.
Assembly of the device and verification of functionality
The Xiaomi Redmi 6A is built in the exact opposite order. Start by installing the motherboard and connecting all the plumes. Make sure each connector is up before the click and is locked. A loosely connected display plume can cause stripes to appear on the screen.
Secure all the screws of the plastic frames, but don't drag them over. The plastic in budget models is quite fragile and can crack with excessive force. After installing all the internal components, plug in the battery and try to turn the device on without closing the back cover.
Check the touchscreen, the cameras, the microphone, the speakers and the vibrations. If all the functions are working correctly, you can gently snap the back cover around the perimeter. Press the corners and faces to the characteristic snap sound.
💡
The basic principle of assembly is that you don't have any extra parts, and if you have a screw or a plastic element left after you build it, then the assembly is not done correctly.
Frequent mistakes in self-disassembly
One of the most common mistakes is to use force where you want to be careful, and if you don't remove it, you probably haven't twisted out some hidden screw or snapped the latch, and if you use excessive force, you're breaking the plastic ears of the mounts.
Another mistake is ignoring the order of screws twisting, screws of different lengths that are not installed in their holes can pierce the board or plume right through, causing a short circuit. Always sort the fastener into groups.
Also, users often forget to turn off the battery before disconnecting other plumes, which can cause the power controller or backlight to burn, and the first action after opening is to turn off the battery.
- ❌ Using metal tools to tamper with plastic
- ❌ Ignoring the sequence of disconnection of plumes
- ❌ Trying to bend the fee for ease of access
