Disassembly Xiaomi Mi Max 2 is a technically complex procedure that requires not only a specialized tool, but also a deep understanding of the design of modern monolithic smartphones. The device has an impressive size and metal body, which imposes special requirements for accuracy at opening, since the risk of damage to the aluminum frame or internal plumes is higher than in plastic models.
Before you start dismantling, you need to be clear about the purpose of the intervention: whether it's replacing a broken display, installing a new battery or cleaning the speaker from dust. Unlike earlier Mi models, there is no removable back cover, and any access to the insides begins with heating the front panel and using a suction cup. The sealability of the case in the factory is provided by a glue layer that will require patience and accuracy to safely remove.
In this article, we will take a detailed look at each step of the process, from the preparation of the workplace to the final assembly, paying special attention to the nuances of working with plumes and fragile components, you will learn how to properly disconnect Flex cables and not damage the connectors on the motherboard, and also analyze the typical mistakes that beginners make when first familiar with the internal architecture of this βtabletβ.
Tools and workplace preparation required
The Xiaomi Mi Max 2 is not a good disassembly without the right equipment, and you need not just a set of screwdrivers, but a specialized toolkit that allows you to work with miniature electronics, based on a set of precision screwdrivers, including cross PH000 and PH00, as well as flat slats for bending contacts, you must have plastic mediators (scapules), a metal blade for primary opening and suction.
The second critical element is the heat source, the glue that holds the display unit melts at about 80-90 degrees Celsius, and the use of a household hair dryer is acceptable, but a professional thermostole or infrared heater will ensure uniform heating throughout the screen area, minimizing the risk of local overheating of the matrix, and you will need isopropyl alcohol to dissolve the adhesive layer and tweezers with antistatic coating.
β οΈ Warning: Using an open fire or building hair dryers with uncontrolled temperature can cause battery bloating or irreversible damage LCD-matrix.
Preparing the workspace is not just about putting things in order, it's about creating a safe zone for small parts. It's recommended that you use a magnetic mat or a cell organizer where each screw will lie strictly in accordance with the disassembly stage. Forget about the chaotic storage of the fastener in a pile: the Mi Max 2 uses screws of different lengths, and screwing a long screw into a short hole can punch through the motherboard.

Primary dismantling: Withdrawal SIM-hull-tray
The first step in the process of disassembling the Xiaomi Mi Max 2 phone is to remove the tray for the device. SIM-This action not only frees up the interior space, but also allows access to one of the screws hidden inside the tray, although in this model the main fastener is located around the perimeter. Carefully inspect the ends of the device for additional hidden screws under decorative plugs, although in the Mi Max 2 they are not, and the main emphasis is on the screws of the lower end.
Then there's the heating step: put your smartphone face up on the heated surface. It takes 3 to 5 minutes to warm up evenly depending on the power of the heat source. Periodically check the surface temperature with the back of your hand, which should be hot but tolerant to touch. Excessive heating is dangerous for the OLED/LCD matrix and the adhesive layers inside the touchscreen.
After warming up, carefully place the suction cup at the bottom of the screen, closer to the Home button (or the Mi logo if the button is virtual). Pull the suction cup up, creating a small gap between the glass and the frame. Insert a thin plastic mediator immediately into the resulting slit. Do not use metal tools at this stage, so as not to break the glass or scratch the aluminum frame.

If the suction cup is not held on broken glass, stick a wide transparent tape over the screen - this will create a smooth surface for clutch and hold the fragments.
Move the mediator along the perimeter, cutting the adhesive layer. The movements should be sliding, parallel to the plane of the screen. Don't try to push the glass up, it will lead to its destruction. Pay special attention to the corners where the glue often remains in large quantities. If the mediator stopped sliding, warm up the device again.
Opening the hull and shutting down the plumes
Once the adhesive layer is passed around the perimeter, you can gently lift the display module. Don't open it completely like a book, because inside are short plumes connecting the screen to the motherboard. A sharp jerking motion is guaranteed to cause the Flex cables to break, which can cost more than the screen itself.
Put the phone down front or lock the screen upright with a suction cup and a load. Your job is to access a metal screen that covers the connectors. In the Xiaomi Mi Max 2, this screen is usually secured with multiple screws. Unscrew them and carefully remove the metal plate using a suction cup or plastic blade.
Under the screen, you'll see the main connectors: the display plume, the touchscreen plume, and the bottom board plume. Use a plastic blade or nail to turn them off. Metal tools are prohibited here, because you can damage the contacts on the board. First, turn off the battery to turn off the device, and then the rest of the plumes.
βοΈ Safe shutdown of plumes
β οΈ Warning: After the battery is turned off, the device may not turn on when you first connect to a charge. This is normal - just leave it on the charger on the charger. 15-20 minute.
Detailed disassembly: Motherboard and components
Once all communications are disconnected, the display module can be completely separated from the body and put away to a safe place, now you have access to the main board, battery and daughter board. The motherboard in the Mi Max 2 is secured by screws and covered with additional metal screens that protect the processor and communication modules.
To remove the motherboard, you need to unscrew all the visible screws that attach it to the frame. Pay attention to the screws hidden under the stickers or in the depths of the holes. You also need to turn off the antenna contacts (usually they are spring-loaded and pinned with screws or simply inserted into the connectors).
The table below shows the main components that require attention in deep disassembly:
| Component | Location. | Features of attachment |
|---|---|---|
| Main camera. | Top of the pay | Inserted into the connector, can be glued |
| Speaker (earpiece) | Upper end | Sticked, connected to contacts. |
| Vibromotor | Next to the buttons | Sticked, plume under the connector. |
| Imprint scanner. | Lower part (on the plume) | Requires careful deflection |
When working with cameras and sensors, be extremely careful. Optical sensors are sensitive to dust and fatty traces - never touch the lenses with your fingers. If the lens gets dust, use a pear to clean the optics, but do not rub it with a cloth without special liquid.

Replacement of the battery and lower board
The battery in Xiaomi Mi Max 2 takes up a significant part of the internal volume and is attached to bilateral tape. Over time, the glue loses its properties, but often the battery is held tightly enough. In no case do not try to tamper with a metal blade or screwdriver - a puncture of the lithium polymer cell will cause an instant fire.
Use a plastic card or a special blade with a cutout to extract safely. Wet the edges of the battery with isopropyl alcohol profusely through the gaps and wait a few minutes for the solvent to penetrate the adhesive layer. Move the tool parallel to the back cover, gradually separating the battery.
The sub-board contains a USB Type-C charging connector (in some Micro-USB revisions, but the Mi Max 2 features Type-C), a main microphone and antenna contacts. It is connected to the motherboard via a main inter-carpage plume. When replacing, make sure that the new plume has the same length and location of contacts, as even a millimeter mismatch will make assembly impossible.
- π The new battery must have a voltage. 3.85V or 3.87V.
- π§© The charging plume often comes complete with a microphone and speakers.
- π§Ή Be sure to clean the frame of the remnants of old glue before installing a new battery.
β οΈ Warning: If the battery is swelling, do not press it. Place it in a refractory container and dispose of it at a specialized battery reception point.
Assembly of the device and verification of functionality
The assembly is done in reverse disassembly. Before the final fixation of the display, it is strongly recommended that an initial check be made. Connect the plumes of the display, touchscreen and battery to the motherboard, but do not glue the screen. Turn on the device and check the operation of the image, sensor, sound, microphone, cameras and charging.
If all functions are working correctly, you can start the final assembly. Apply a new adhesive (B-7000 or analog) in a thin layer on the frame of the case. Let the glue dry slightly (2-3 minutes) so that it does not squeeze out when pressed. Carefully combine the display module with the frame and tightly press around the perimeter.
For reliable fixation, use rubber harnesses or stationery gums, wrapping them around the phone in several directions. Leave the device to dry for at least 2-3 hours, preferably overnight. Complete polymerization of the glue and restoration of leakage take up to 24 hours, so on the first day avoid moisture and dust.

The main mistake in the assembly is to try to press the screen hard at once, and the glue needs time to grasp, otherwise the module may shift or a gap may appear.
