How to disassemble Xiaomi Mi A6 (6A) without damage: instructions with photos and nuances

The Xiaomi Mi A6 (also known as the Mi 6A in some regions) is a compact smartphone with good hardware, but over time even it may need repairs: battery replacement, plug cleaning, or motherboard diagnostics. Disassembly of this device has its own peculiarities due to the adhesive mounting of the rear cover and fragile plumes. In this article, you will find a step-by-step photo instruction, a list of necessary tools, as well as critical nuances that even experienced craftsmen miss.

Before you start, consider: self-disassembly Xiaomi 6A is warranty-free (if it is still valid) and can damage plumes or chips if you have never disassembled smartphones, practice on an old device or contact the service center. However, if you decide to repair yourself, our recommendations will help avoid mistakes.

Unlike Xiaomi’s flagship models, which often use latches, the Mi A6 has a perimeter-plated back cover and adhesive-based battery, which complicates the process, but with the right approach, disassembly will take no more than 30 to 40 minutes, the main thing is to take your time and follow the instructions Step-by-step.

Preparation for disassembly: tools and security measures

To disassemble the Xiaomi Mi A6, you need a specialized set of tools, and using improvised tools (knives, screwdrivers of the wrong size) is almost guaranteed to damage the body or internal components.

• 🔧 Plastic mediators (2-3 pieces) - for careful liding.
• 🔨 The screwdriver. PH00 — rear-cover.
• 🔋 Suction (optional) - helps to lift the cover after heating.
• 🔥 Hair dryer or thermo-air station - for softening the glue (temperature not higher than 60)°C!).
• 🧴 Isopropyl alcohol 90%+ — glue-residue.
• 📦 Container for screws - so as not to lose small details.

Pay special attention to the temperature regime when the case is heated. Overheating above 70 ° C can damage the screen or battery. The optimal range is 50-60 ° C. Also, never use metal tools to lash the lid - this leads to microcracks on the camera glass or antenna lines.

⚠️ Warning: If your smartphone battery is swelling, don't heat the case or try to disassemble it yourself! A bloated battery can ignite when it's mechanically exposed.

Step 1: Removing the back cover - how not to damage the glue and plumes

The most critical step is to separate the back cover, and in the Xiaomi Mi A6, it's glued around the perimeter, and underneath it are fingerprint plumes and antenna contacts, and if you act rudely, you can tear them or leave some glue on the lid, which makes it difficult to reverse assemble.

Algorithm of action:

1. Turn off your smartphone and remove it. SIM-map.
2. Heat the back cover with a hair dryer for 2-3 minutes, evenly driving around the perimeter.
3. Insert a plastic mediator into the gap between the lid and the case (start at the bottom edge where the USB-C connector is).
4. Carefully drive the mediator along the edge, gradually lifting the lid. If you feel resistance, warm up the place again.

When the lid is 1 to 2 mm up, don't try to tear it completely off, and underneath it are the fingerprint scanner plumes and the flexible antenna cables, which you have to unplug before the lid is completely removed.

• 🛠️ Unscrew 2 screws fixing the metal plate over the print plume.
• 👆 Carefully tuck the plume with a plastic spatula and disconnect it from the connector.

If the glue is too strong, you can use isopropyl alcohol: apply a few drops in the gap and wait 1-2 minutes - it will dissolve the glue. But do not overdo it: alcohol can damage rubber seals.

Step 2: Removing the battery – why you can’t pull the wires

The battery in the Xiaomi 6A is glued to the body, and improperly removing it is one of the main causes of short circuits.Never pull the wires or connector - this can tear off tracks on the board or damage the power controller.

Procedure:

1. Unscrew 4 screws that fix the metal plate over the battery.
2. Disconnect the battery connector with a plastic spatula (not metal!).
3. Tap the battery with a plastic card or a special battery retrieval tool. Start at the edge where there are no board components.
4. If the battery is not amenable, apply a few drops of isopropyl alcohol under it and wait 5 minutes.

⚠️ Warning: If the battery is blown up, do not use alcohol - it can leak in and cause a chemical reaction.

After the battery is removed, check it for swelling or corrosion. If the battery capacity has fallen below 70% of its nominal capacity (the original capacity is 3080 mAh), it is better to replace it. The new battery should have the same parameters (voltage 3.85V, capacity 3000-3100 mAh).

Step 3: Unconnecting the motherboard - which screws can not be lost

The Xiaomi Mi A6 motherboard is mounted on 12 screws of different lengths, easily confused, and an incorrect puff during assembly can damage the board, and we recommend taking a picture of the location of each screw or stacking them in order in the container.

Disassembly order:

1. Disconnect all plumes: 📱 Main display plume (fixed with a metal latch). 🔊 Dynamics and microphone plume. 📶 Antenna cables (3 pcs, glued to the board).

USB-C

Carefully tuck the board with a plastic spatula from the edge where there are no components.

When removing the board, be careful with flexible antenna cables — they are glued to it and can come off. If you need to replace a USB-C or 3.5 mm audio connector, they are soldered on the board, and this will require a soldering station with a thin sting.

💡

If the screw doesn't unscrew, don't force it -- it can rip the slits off. Instead, drop WD-40 or alcohol on it, wait 5 minutes and try again.

Step 4: Disassemble the front panel - screen and buttons

Xiaomi. 6A It's glued to a frame, and replacing it is one of the most difficult operations. OCA-With adhesives that are optically transparent, you'd better trust the professionals to do that, but if the screen is cracked, but the touchscreen is working, you can try replacing it yourself.

For screenshots:

1. Warm up the front panel with a hair dryer (temperature 50–60 °C).
2. Insert a plastic mediator into the gap between the screen and the frame (start at the top edge).
3. Carefully drive the mediator along the edge, separating the glue, if the screen cracks, paste it with tape so that the fragments do not fly apart.
4. Disconnect the screen plumes and touchscreen (they go together, but split on the board).

Another common problem is that antenna lines get damaged when you sloppyly remove the lid, and they're on the sides of the hull, and they look like thin copper tracks, and if one of them breaks, the 4G or Wi-Fi signal gets degraded.

💡

The most vulnerable part of the Xiaomi 6A disassembly is the fingerprint scanner plume, which causes the sensor to lose functionality, and replacing the plume requires soldering on the board.

Build a smartphone: what to pay attention to

The Xiaomi Mi A6 should be assembled in reverse order, but with a few key points in mind:

1. Before installing the battery, clean the contacts on the board and battery with isopropyl alcohol.
2. Stick the back cover onto a new double-sided tape (e.g. 3M 9448A) the old glue loses its properties after heating.
3. Tighten the screws cross-cross to avoid skewing the board.
4. After assembly, check the operation of all sensors (gyroscope, accelerometer, compass) in the engineering menu (#4636##).

If after assembly the smartphone does not turn on:

• Check if the battery connector is connected.
• Make sure that the display plumes and touchscreen sit tightly in the connectors.
• If the charging indicator does not burn, the problem may be in the USB-power-connector.
