Xiaomi Mi 6A series smartphones have proven to be reliable devices, but over time, even the most durable equipment requires intervention. Replacing broken glass, installing a new battery or cleaning speakers are tasks that often arise for gadget owners after a year or two of active use. Many users are afraid to start self-repair, fearing damage to fragile plumes or break the latches of the case.
However, if you act carefully and have the right set of tools at hand, the dismantling procedure becomes quite accessible even for beginners. The key here is to understand the design of your particular device, since in the Xiaomi lineup there are often models with different types of rear mounting. In this article, we will discuss the dismantling process in detail, paying special attention to the nuances of working with adhesive base and plastic elements.
Before you start physically affecting the body, you need to prepare the workplace, you need a clean surface with good lighting, where dust and small parts do not get into, and you should not ignore this stage, because a lost cog or a villi that gets inside can negate all repair efforts.
Tools and workplace preparation
The success of any electronic repair operation depends on 80% on the quality of preparation. To remove the lid on the Xiaomi Mi 6A, you will need a specific but affordable toolkit. Using inappropriate items such as kitchen knives or thick needles can lead to permanent damage to the frame and internal components.
First of all, get a suction cup. It's the most important element for the primary detachment of the panel. If you don't have a professional suction cup, you can use a similar tool from the smartphone repair kits that you sell in any electronics store, and you'll need mediators or plastic blades, which are necessary for walking around the perimeter of the case.
- 🔧 Set of screwdrivers: mandatory presence of a cross screwdriver PH000 or PH00 screw-twisting.
- 🌡️ Hair dryer or thermophen: necessary for heating the adhesive layer, without this step to remove the lid of the whole is almost impossible.
- 🧤 Protective gloves: help avoid fingerprinting on internal components and protect against cuts against glass.
Pay special attention to the source of heating. Household hair dryer may not give enough temperature, so it is better to use a temperature-adjusted building hair dryer or at least a powerful hair dryer at maximum mode. The temperature regime should be adjusted so that the glue softens, but not melt the plastic of the case.
Features of the design of the Xiaomi Mi 6A
Understanding how your smartphone works is critical before you start disassembling. Xiaomi models, including the 6A series, often use a combined mounting method: screws are hidden under decorative elements, and the panel itself is held on double-sided scotch or a special adhesive. Unlike older phones with removable batteries, here the back cover is part of the supporting structure.
Inside the case, there are sensitive plumes connecting the main board to the camera module, speakers and buttons. Sloppy movement of the blade can damage the connectors, which will cause individual functions of the phone to fail even after successful assembly. Often manufacturers have a speaker plume at the bottom, closer to the charging connector.
⚠️ Note: In some versions of Xiaomi Mi 6A The fingerprint scanner can be integrated into the back cover, so before you completely separate the panel, make sure you don't damage the plume connecting the scanner to the motherboard.
Also consider the body material. If you have a plastic version, it's more flexible, but more easily scratched by tools. Glass versions require even more caution when heated, as a sharp temperature drop can cause cracks. Always check the model for hidden screws under the logo or at the bottom of the frame.
The process of heating glue and primary detachment
The most important step is to soften the latching layer. The glue used in modern smartphones has high adhesion at room temperature. To remove the lid on the Xiaomi Mi 6A without damage, you need to evenly warm the perimeter of the device.
Turn on the dryer and direct the hot air to the ends of the smartphone. Keep the tool 3-5 centimeters from the surface, constantly moving it to avoid local overheating. The process takes 2 to 5 minutes depending on the power of the device. Plastic or glass should become warm, but not hot enough that they can not be held in the hand.
💡
Use an infrared thermometer if you have one. The optimal heating temperature for the edge of the case is 60-70 degrees Celsius. Exceeding 80 degrees can damage the display or battery.
After warming up quickly but carefully, install the suction cup on the bottom of the back cover, stepping about 1-2 cm from the edge. Pull the suction cup up, creating a vacuum, and simultaneously insert a thin plastic blade or mediator into the resulting micro-gap. Don't use the force of the jerk, act smoothly.
| Phase | Heat time | Tool. | Risk |
|---|---|---|---|
| Initial warming up | 2 minutes. | Fen | Low. |
| Introduce the shoulder blade | 30 seconds | Suction cup + Mediator | Medium (scratches) |
| Longitudinal section | 1 minute (warming) | Scapula | Tall (trains) |
| Final withdrawal | - | Hands. | Medium (cracks) |
Technique of safe opening of the perimeter
When the blade has entered the gap, the process of separating the layers begins, and your task is to hold the tool along the perimeter, cutting the adhesive layer. Move slowly, feeling resistance. If the blade is too tight, do not press harder, you better warm the area again with a hairdryer.
Be careful where you go in the corners of the case, and that's where the glue accumulates, and that's where the most vulnerable elements are, and the plastic latches, if they're in your modification, give off the characteristic click when you unbutton them, and don't be afraid of that sound, but don't put too much effort into it.
☑️ Safe opening of the hull
As you move around, gradually increase the gap. You can use a second blade to fix the already detached areas and prevent the glue from grabbing back, and it's important not to bury the tool more than 3-4 millimeters inside the case so as not to touch the battery or board.
Disabling the plumes and the final withdrawal
When you've walked around the perimeter, don't rush to tear the lid off abruptly, at which point it can only hold on one or more plumes, gently lift the bottom of the lid and inspect the interior space in good light.
If you see thin flexible cables going from the main board to the modules on the lid (camera, flash, scanner), they need to be turned off. Use a plastic blade or blunt-ended tweezers. Connectors are usually pressed on top or have a side latch.
⚠️ Attention: Never pull the plume itself! You need to turn off the connector by gently lifting it upwards. The pulling force will tear the thin conductive paths inside the cable.
After all communications are turned off, the back cover should be removed freely.Put it in a safe place, preferably on a soft fabric, with the outside down so as not to scratch the gloss or glass.Now access to the insides of the Xiaomi Mi 6A is completely open.
What to do if the plume is broken?
Typical errors in disassembly
Even experienced craftsmen sometimes make mistakes, let alone beginners, and one of the most common problems is trying to remove the lid cold. Without proper heating, the glue remains hard, and the application of force leads to cracks in the back panel or deformation of the frame.
Another common mistake is using metal tools (knives, scalpels) to slid the lid. Metal slips easily and can short contacts on the board or damage battery insulation, which can cause fire. Always use only dielectric tools made of plastic.
- ❌ Ignoring screws: Trying to open the lid without twisting the hidden screws (if you have them in your version) is guaranteed to break the plastic racks.
- ❌ Excessive heating: Overheating of the battery can cause it to swell or fail, as well as detachment of the oleophobic coating on the screen on the other side.
- ❌ Loss of screws: small fasteners can easily roll under the table. It is recommended to use a magnetic mat or spread the screws in order of their twisting.
Be careful of the little things. If something doesn't go as described in the manual, stop and double-check the information. Forced process is the main enemy of successful repairs.
Assembly and restoration of leakage
After the necessary repairs (replacement of the battery, cleaning the speaker) comes the assembly stage. Just snap the lid back, it will hang around and dust. You need to restore the adhesive layer.
To do this, use a special glue B-7000 or T-7000, or a pre-prepared double-sided tape for phones. Carefully clean the frame and the lid of the old glue with alcohol or a special cleaner. Degreasing is a must for good adhesion.
💡
The quality of cleaning the frame from the old glue directly affects the final tightness and density of the adhesive back cover.
Put a thin strip of glue around the perimeter of the frame, avoiding cameras and speakers. Put a lid on it, put all the holes together, and press the edges tightly. You can use stationery gums to fix it, wrap it around the phone. 15-20 minutes until the glue is grasped.
