Disassembling the Xiaomi Redmi 6 is a process that requires careful understanding of the design of the device, as this budget device has its own build features. Unlike many modern models, it uses a classic scheme with a non-removable rear cover, which greatly complicates access to the internal components. The main difficulty is that the rear panel is glued to a powerful layer of glue, rather than fixed screws, which requires heat treatment and special tools.
Many users are faced with the need to open the case when replacing the battery, repairing the charging connector or replacing a broken display. It is important to understand that opening the Redmi 6 case automatically leads to a loss of warranty if it was still in force at the time of contacting the service. However, if you decide to act on your own, you will need not only patience, but also a quality set of tools for working with microelectronics.
In this article, we will take a detailed look at each stage of dismantling, from the preparation of the workplace to the removal of the motherboard, and following the sequence of actions will help you avoid damage to plumes and plastic elements, which can be very fragile after prolonged use.
Tools and workplace preparation required
Before any electronic manipulations begin, you need to provide a safe and comfortable workspace. You need a well-lit desk, preferably with an antistatic coating or just a clean surface where small screws are not lost. Quality lighting is critical, since many of the fasteners in Redmi 6 are microscopic in size.
To do the job, you will need specialized tools that can be purchased in radio parts stores or online. Using improvised tools such as knives or pins is highly undesirable, as there is a high risk of damage to internal components or scratching the case.
- 🔥 A hair dryer or thermophen to soften the glue under the back cover.
- 🔧 Set of screwdrivers (cross-haired) P2, P5 and flat) for screw twisting.
- 🏴 Mediator or thin plastic blade for snapping latches.
- 🧲 Magnetic mat or organizer for sorting screws of different sizes.
It is also recommended to have a suction cup on hand to help suction the back cover after heating.Isopropyl alcohol and a thin syringe may be needed to dissolve the glue residues when reassembled if you plan to use an old adhesive compound.
☑️ Preparation for disassembly
The procedure for removing the back cover of the smartphone
The most time-consuming step of dismantling Xiaomi Redmi 6 is to carefully separate the back from the metal frame. the Factory glue over time polymerizes and becomes very hard, so heating is a prerequisite for a successful start. Put the phone screen down on the soft fabric and evenly warm the perimeter of the back cover with a hairdryer for 2-3 minutes.
Don't try to remove the lid immediately after a short heating period, as the adhesive in the corners may remain solid. Once the body is warm to the touch, apply a suction cup at the bottom of the back panel and slightly pull up, while inserting the mediator into the gap.
⚠️ Warning: Do not heat your phone too much so as not to damage the battery or display on the back. 80-90 Celsius, when holding your hand on the surface becomes uncomfortable.
Move the blade or mediator along all sides of the device, trying not to immerse the tool too deep, so as not to touch the plumes that go to the side buttons. Plastic latches are located around the perimeter, and they must be carefully snapped, leading the tool parallel to the plane of the body.
What to do if the lid does not open?
Dismantling of the battery and protective panels
Once you successfully remove the back cover, you will have an interior space where most of the area is occupied by the battery. In the Redmi 6, the battery is also attached to double-sided tape, which requires re-application of thermal exposure. Before any action with the insides, the first thing you need to do is to disconnect the battery plume from the motherboard.
To do this, carefully bend the protective plastic lining covering the connectors and use a plastic blade to detach the connector. Power outage is a critical step to prevent short circuits from accidentally touching the contacts with a tool.
To remove the battery itself, use a hairdryer again, warming up the back of the device (now a metal frame on the inside). Under the battery are often special retractable tongues, but in budget models they may be missing or glued.
| Component | Type of attachment | Risk of damage | Tool. |
|---|---|---|---|
| Back cover. | Glue + latches | Tall (cracks) | Fryer, sucker. |
| Battery | Double-sided scotch | Medium (puncture) | Fen, plastic card |
| Maternity fee | Screws + plumes | Tall (trains) | Screwdriver, tweezers. |
| Screen. | Perimeter glue | Critical (breakdown) | Fryer, string |
Lift the battery with a plastic card or a spatula, and if you feel a lot of resistance, add a little more heat. Lithium polymer batteries are very sensitive to mechanical damage, and they can cause a fire to puncture.
Disassembly of the main board and removal of modules
Access to the motherboard in Xiaomi Redmi 6 opens after removing the battery and the bottom plastic panel covering the charging connector. the motherboard is fixed with several screws that must be twisted in a certain sequence to avoid skewing.
Look carefully at the board, and you'll see a few plumes connecting the main board to the lower sub-board, where the charging connector, microphone and main speaker are located, and these plumes are very thin and easily torn, so turning them off requires a hard hand and good tweezers.
First, disable all visible connectors, then unscrew the screws holding the board.Note that some screws may be hidden under stickers or rubber plugs. Once the mounts are free, the board is easily retrieved, but be careful with the main camera module, which can protrude.
- 📱 Turn off the display plume located at the top of the board.
- 🔌 Carefully remove the antenna connector if it interferes with the dismantling.
- 🔊 Remove the vibrator motor, which is often glued to the frame or held on latches.
When you reverse install the board, make sure all connectors are up before the click.A loose connection can cause the touchscreen, speaker, or network to fail.
💡
The main rule when working with the board is never pull the plumes, always take only the hard connectors or the board itself.
Replacement of the screen and touch screen: design features
The Redmi 6 model is used in IPS-It's almost impossible to replace the glass (touchscreen) separately from the matrix at home without special equipment, so you usually change the entire module assembled with or without a frame.
If you change a frameless module, you'll have to glue the old screen to a new body, or transfer components from an old broken module. This process requires heating the edges of the display and carefully separating the layers. The glue under the screen is unevenly distributed, and heating helps soften it for safe removal.
⚠️ Attention: When you remove an old screen, you are at high risk of breaking it. If the glass cracks, the shrapnel can fly apart, so use safety glasses.
The new screen should be tried on before installation, checking the touchscreen and images to the final sticker, plug the plumes, turn on the phone and make sure that there are no defects, only after successful testing, apply a new glue B-7000 or a special adhesive layer.
💡
Use rubber rings or stationery gums to tightly press the screen against the frame while the glue is drying for 1-2 hours.
Assembly of the device and verification of functionality
The final step is to build the Xiaomi Redmi 6 in reverse order. Make sure that all the screws are returned to their places, as the absence of even one fastener can lead to backlashes or creaks of the body during operation. Pay special attention to the stacking of the plumes: they should not be clamped or broken.
Before sticking the back cover, be sure to check all the functions: cameras, speakers, microphone, vibration and touch buttons. Testing on an open case will save you time if you find a broken component that needs to be replaced or reconnected.
To fix the back cover, apply a thin layer of special glue around the perimeter of the frame. Do not use superglue, as it can damage plastic or leave white marks that cannot be removed. After pressing the lid, leave the phone under the press (for example, under a stack of books) for a few hours.
