Disassembling the Xiaomi Mi6 is a process that requires not only accuracy, but also a deep understanding of the design of the device. This flagship, released in 2017, is still appreciated for its characteristics, but time takes its toll: batteries wear out and screens break when falling. Self-repair can extend the life of the gadget and save a significant amount, but only if you strictly adhere to the technology.
Before you start dismantling, you have to prepare the workplace, you need a clean, well-lit surface so that no small screw piece gets lost in the dust, and ignoring this stage often leads to the assembly becoming a complex puzzle with extra details.
The main challenge with the Xiaomi Mi6 is its design: the back panel is made of glass and glued around the perimeter, and inside is a dense arrangement of components. Any careless movement can damage the plumes or cracks in the glass. The main risk area when opening is the plume of the fingerprint scanner, which is attached directly to the inside of the back cover and breaks when sloppy lift.
⚠️ Warning: Before starting any work, be sure to turn off the smartphone. Attempting to disassemble the enabled device is guaranteed to short circuit and the motherboard will fail.
Tools and workplace preparation required
For a good disassembly of the Mi6, a regular set of screwdrivers will not be enough. You will need specialized tools that will allow you to work with adhesive joints and miniature screws. Using inappropriate items such as knives or needles increases the risk of damage to the body at times.
First of all, get a heating element. This can be a special heater (pre-heater), a temperature-adjusted thermophen or, in extreme cases, a dense package of hot water. The glue that holds the back cover softens at a temperature of about 80-90 degrees Celsius. Without heating, the glass will simply burst under pressure of the mediator.
- 🔧 A set of precision screwdrivers (mandatory presence of cross-shaped) P2 and Pentalobe, if the lid on the screws, although in Mi6 more commonly used).
- 🔥 A heating pad, thermophene or electric tile for heating the adhesive layer.
- 💳 Plastic mediators, screen suction cup and thin metal scalpel (for primary suction).
- 🧴 Isopropyl alcohol and glue base B-7000 or T-7000 reverse-assembly.
Special attention is paid to the organization of space. It is recommended to use a magnetic mat or to arrange the screws in a strict sequence of twisting. Xiaomi Mi6 uses screws of different lengths, and if you screw a long screw into the hole for a short one, you can punch through the board, which would be a fatal mistake.
Removal of the rear glass panel
The beginning of the disassembly is always the most important. The back cover of the Xiaomi Mi6 is supported by a powerful layer of glue, which over time hardens even more, and your task is to evenly warm the perimeter of the device without overheating the display matrix on the front side.
Place your smartphone with the back panel up on the heating element. Heating time is 3 to 5 minutes depending on the power of the heat source. Periodically check the temperature with your finger (caution, it can be hot) - the glass should become noticeably warm, but not hot.
💡
Use a thermometer or an IR pyrometer if possible. The ideal temperature for warming the adhesive is 85°C. Exceeding 100°C can damage the internal plastic frames and deform the polymers.
After warming up, suck the suction cup at the bottom of the back cover, closer to the Mi logo, but not at the very edge. Pull up a little bit, creating tension, and insert a thin mediator or scalpel blade into the gap. Move the tool along the perimeter, cutting the adhesive layer.
⚠️ Note: Do not enter the instrument deeper 2-3 Inside the case, plumes and components start immediately. Deep immersion of the scalpel can damage the battery or the plume of the fingerprint scanner.
When you're past the perimeter, don't take the lid off abruptly. Turn the phone over and gently lift the glass to access the insides. Inside, you'll see a metal plate covering the fingerprint scanner plume, and it's screwed with one or two screws.
Unscrew the screws of the safety plate and remove it, and only then can you completely unplug the back cover, first disconnecting the scanner plume from the motherboard, and the scanner plume is a very fragile element, and if you damage it, you will be deprived of the fingerprint unlock function.
Dismantling the battery and motherboard
When you remove the back cover, you'll see the interior architecture of the smartphone, the motherboard that's covered with a black plastic cover, the battery on the top, and the battery on the bottom, and the top protection plate on the main nodes is removed to access the main nodes.
Carefully unscrew all visible screws that fix the plastic lining. Note that some screws may be hidden under stickers or rubber plugs. After removing the protection, disable the display plumes, touchscreen and main charging plume from the motherboard.
☑️ Procedure for disconnecting plumes
Now you can take the battery out. In the Xiaomi Mi6, it's also glued. Under the battery, there's often a plume of the main speaker, so you have to be very careful. Use a plastic blade soaked in isopropyl alcohol and slowly put it under the battery, making sawing movements.
Do not try to push the battery over the edge with force, this can cause it to puncture and fire. If the battery is swelled, you need to work with it with double caution, trying not to damage the shell.
| Component | Type of attachment | Risk of damage | Tool. |
|---|---|---|---|
| Back cover. | Clay (B-7000) | Tall (glass shattering) | Suction, mediator. |
| Maternity fee | Screws + plumes | Medium (steel break) | P2 screwdriver, tweezers |
| Battery | Glue + frame | Critical (fire) | Scapula, alcohol |
| Screen (OLED) | Glue + frame | Tall (matrix fight) | Thermophen, sucker. |
To remove the motherboard, you also need to remove the sub-board where the charging connector is located, which is mounted with screws and a plume, and after disconnecting all connections, the board is freely removed from the case.
💡
Follow the shutdown sequence: always turn off the battery first to turn off the system before working with other plumes.
Replacement of the display and touch screen
Xiaomi. Mi6 fixed AMOLED-The display, which is the most expensive component of the smartphone after the motherboard.Screen replacement is often required after falls, even if the outer glass is intact, but the matrix went in stripes or broke from the inside.
The process of replacing the display begins with the complete dismantling of all the internal components described above, the screen is glued into the metal frame of the case, and to remove it, the body must be warmed up again around the perimeter of the front panel.
Use a thin string or a special glue cutting knife to separate the matrix from the frame. The movements should be smooth, without jerking. The old screen will most likely be permanently damaged, but your goal is not to damage the frame of the case.
⚠️ Warning: When installing a new display, make sure that there are no pieces of old glue or glass left on the frame. Any unevenness will cause the new one to become a new one. AMOLED-The screen will crack at the first press or assembly.
The new display should be checked before the sticker is inserted. Connect the plumes to the motherboard without pasting the screen, and launch the smartphone. Check the touchscreen, the presence of broken pixels and color reproduction. Only after successful verification, apply a new layer of glue and fix the module.
Assembly of the device and verification of functionality
The Xiaomi Mi6 is assembled in reverse order, but requires even more care. Before gluing the body, you must carefully clean all surfaces of old glue. Use alcohol and a lilaless wipe for degreasing.
Apply a thin layer of special adhesive (e.g., B-7000) to the frame of the case. Don't apply too much glue, otherwise the excess glue may squeeze in and damage the components, or stain the new screen. Let the glue dry a little (2-3 minutes) before the final press.
What if the phone does not turn on after assembly?
Put all the screws in their places, keeping them in length and type. Rotate them cross-wise to ensure that the boards fit evenly. Once the back cover is installed, lock the smartphone with money bands or a special clip for 15-20 minutes to polymerize the glue.
After assembly, turn on the device and conduct a comprehensive check: display test, camera, microphone, speakers, vibrator and communication modules (Wi-Fi, Bluetooth, GSM). Pay special attention to the fingerprint scanner, as its plume suffers most often.
Frequent mistakes and expert advice
Self-repair is always a risk. Even experienced craftsmen sometimes make mistakes, let alone beginners. One of the most common problems is damage to plumes when tweezers are not handled carefully. Always take the plumes by the thickened edges, never pull the track itself.
Another common mistake is ignoring the heat sink. When assembled, make sure that the graphite pads and copper thermoplastic are installed in their places. In the Xiaomi Mi6, the cooling system is compact, and the lack of contact can lead to overheating of the processor and trotting.
- 🚫 Do not use superglue (cyanacrylate) to stick the lid – it emits fumes that settle on cameras and sensors, disabling them.
- 🔋 When replacing the battery, try not to bend it too much, lithium polymer cells are sensitive to deformation.
- 🧹 Before closing the case, blow the insides with compressed air to remove dust and villi.
If you feel insecure at any stage, it's best to stop, the cost of making a mistake may exceed the cost of a service center, but if you decide to go all the way, calmness and mindfulness are your main tools.
💡
Keep all packaging materials from new parts, and if a new part is defective, it can only be returned or exchanged in the original packaging.
The properly assembled Xiaomi Mi6 will work like a new one, delighting with the speed and quality of shooting. Repairing with your own hands gives not only savings, but also confidence in the quality of the work performed.
