Modern smartphones like the Xiaomi Redmi 6 often require intervention in their internal design, which can be caused by a broken display, a failed battery or a faulty conversational speaker. Self-disassembly of the device allows you to save a significant amount of money on the services of the service center, but requires extreme care and accuracy.
Before work begins, the Redmi 6 has a plastic back cover that attaches to glue and latches, which makes it easier to remove, but requires caution when snapping so as not to damage the plumes. In this article, we will look at each stage of dismantling, from preparing the workplace to unplugging the motherboard plumes.
A well-conducted procedure ensures that the phone will work properly after assembly. It is important to prepare all the necessary tools in advance so as not to search for them during operation. Lack of the right tools can damage the body or internal components, so do not neglect the preparatory stage.
Tools and workplace preparation required
To successfully disassemble the Xiaomi Redmi 6, you will need a minimum set of specialized tools. The use of inappropriate items such as kitchen knives or thick screwdrivers is strictly prohibited, as they can damage fragile structural elements.
You'll also need a set of precision screwdrivers, usually like Phillips #00 or PH000, to twist screws that lock the internal modules, and you'll need an antistatic blade to help you safely detach the plumes and lift the components without leaving scratches.
- 🛠️ Precision screwdriver kit (cross-hatch) PH000)
- 📦 Plastic suction cup or mediator to open
- 🔌 Tweezers with dielectric tips
- 🔥 Hair dryer or heating platform (to soften glue)
The workplace should be well lit and free of unnecessary objects. Small screws have the property of flying around the table and getting lost, so it is recommended to use a magnetic mat or container with cells to sort the fastener by dismantling stages, this will help you not to confuse anything when you build it back.
💡
Use a magnetic mat or draw a diagram of the screws on a piece of paper, gluing them with tape – this will save you hours of searching when Assembly.
Removal of the back cover and primary access
The process of opening the Redmi 6 body starts with dismantling the back panel. Since it is glued around the perimeter, you need to preheat the glue. Use a construction dryer, warming the edges of the back cover for 1-2 minutes. The temperature should not be too high to melt the plastic, 60-70 degrees is enough.
After warming up, insert the suction cup into the bottom of the back cover and pull up slightly to create a gap. Insert a plastic card or mediator into the resulting gap. Lead the instrument along the perimeter of the case, cutting through the adhesive layer. Move slowly so that the fingerprint scanner plume does not damage if it is laid close to the edge.
⚠️ Warning: Do not try to cover the lid with metal objects! this will cause plastic chips and can damage the internal components located close to the body.
When all the latches are snapped, the lid can be easily removed. However, don't make sudden movements. Inside, there may be a plume connecting the fingerprint scanner to the motherboard. In the Redmi 6, the scanner is often located on the back cover, so be extremely careful when putting the panel aside.
What to do if the lid does not open?
Dismantling the battery and protection of the board
When you take the back cover off, you see the inside of your smartphone, and the first thing you need to do is turn off the power to avoid short circuits, find the battery connector on the motherboard, and gently disconnect it using a plastic blade or nail, which is a critical step before any further manipulation.
The battery in Xiaomi Redmi 6 is mounted on double-sided tape. You can use a suction cup or special plastic levers to extract it. It's dangerous to poke the battery with metal tools, a puncture can cause fire. If the battery sits very tightly, you can slightly warm up the case in the battery area with a hairdryer.
| Component | Type of attachment | Withdrawal tool | Features |
|---|---|---|---|
| Back cover. | Glue + latches | Suction, mediator. | It requires heating. |
| Battery | Double-sided scotch | Plastic spatula | Fire-prone when punctured |
| Maternity fee | Screws + plumes | Screwdriver PH000 | Many small screws |
| Screen. | Sticky frame. | Thermoplate, sucker. | Fragile module |
Once the battery is removed, you'll have access to the bottom of the case, where the motherboard's mount screws are located, and you'll have to unscrew them, and you'll also have to remove the plastic protective lining that covers the connectors and the plumes, which is usually held on a few screws and plastic latches.
☑️ Safe operation with the battery
Disconnection of plumes and removal of motherboard
The motherboard is the brain of your Redmi 6 smartphone, held by multiple screws and connected to the body by multiple plumes, including display plumes, touchscreen, volume and on buttons, and the main and front camera modules.
Start disconnecting the plumes from the most accessible ones. Use a plastic blade to lift the connector upwards. Don't pull the plume itself, just the thickened connector. A sudden movement can break thin conductive tracks, and it's almost impossible to repair them at home.
- 📷 Disconnect the main camera plume
- 📱 Carefully disable the display plume and touch screen
- 🔊 Remove the lower charge plume (charging)
- 🔌 Turn off the antenna cable (if it interferes with the cable)
Once you've shut down all communications, unscrew all the visible screws that attach the board to the case. Notice the screws under the stickers or rubber plugs. The board should come out freely. If anything disturbs, check again if all screws are twisted and if all plumes are turned off.
💡
The order of disconnection of plumes is not critical, the main thing is not to damage them mechanically and not to lose small screws that can fall out of the holes.
Replacement of the display module and touch screen
Replacing the screen with Xiaomi Redmi 6 is one of the most common reasons for disassembly. The screen here is glued to the frame of the case. To replace you need to completely remove the old frame with broken glass or carefully separate the glass from the frame, which is extremely difficult to do at home.
The easiest way to buy a framed screen is to move the motherboard, battery and speaker bottom board to a new frame, which will take less time and ensure that there are no problems with glue and tightness.
If you only change the glass (touchscreen), you'll need a separator or heat to separate the layers, which is a complex process that requires experience. When you install a new module, make sure that the protective film from the adhesive layer is removed, and press the screen tightly around the perimeter.
⚠️ Warning: Before turning on the phone after changing the screen, be sure to check the plume connection.Switching on with an unconnected or skewed plume can burn the power controller on the board.
Assembly of the device and verification of functionality
You do the reverse assembly. You put the motherboard in place, you twist the locking screws, you plug all the plumes into the right click, and you make sure that no plume is squeezed or placed on the sharp edges of the metal.
Connect the battery and try to turn the phone on without sticking the back cover. Check the touchscreen, sound, cameras and Wi-Fi. If everything is working correctly, you can stick the back cover. Use a special glue B-7000 or double-sided tape for phones.
Apply the glue thinly around the perimeter, press the lid and lock with rubber bands for 15-20 minutes before drying. After final assembly, wipe the screen and the body from the fingerprints. Your Redmi 6 is ready to go again.
Regular maintenance and careful handling will extend the life of your device, so you now know how to disassemble your phone, and you can fix minor malfunctions on your own, saving time and money.
