Disassembly Xiaomi Redmi 6A: how to carefully remove the back cover and not break the latches

The Xiaomi Redmi 6A is one of the brand’s most popular budget smartphones, but its maintainability leaves much to be desired. The back cover of the model is attached to latches and adhesive layer, making it difficult to disassemble without damage, and this instruction will help remove the panel carefully, even if you have never taken your phones apart before.

The main problem with removing the Redmi 6A cover is the brittle plastic clips around the perimeter of the body, which are easy to break if you use excessive force or use the wrong tools. In this article, we will analyze the correct disassembly technique, list the necessary tools and explain how to avoid typical errors that lead to cracks in the body or damage to the plumes.

We'll focus on workplace preparation and safety precautions, like why you can't take your phone apart on a carpet or how to store your screws properly so you don't mix them up when you're back-assembling. If you're planning to replace your battery, speaker or camera plume, this guide is the first step to a successful repair.

Preparation for disassembly: tools and safety

Before you start removing the lid, make sure you have everything you need, and the absence of even one tool can cause permanent damage to plastic latches or flexible plumes inside the housing.

Here is the minimum set that will be required:

• 🔧 Plastic blade (or mediator) - for tidy lid lashing. Metal tools leave scratches!
• 🧲 Magnetic mat or screw container – to avoid losing small details.
• 🔥 Hair dryer or thermal air station - for softening the adhesive layer (temperature not higher than 60)°C).
• 📸 Smartphone for photography – fix the location of plumes and screws before turning off.
• 🧴 Isopropyl alcohol (90%+) — cleaning the residue of glue after removing the cover.

Also prepare the workplace:

• 🪑 Use a table with a flat surface, preferably covered with an antistatic mat.
• 💡 Lighting should be bright – backlighting on both sides will help to avoid shadows.
• ⚡ Turn off the phone and remove it. SIM-map + Memory card (if installed).

⚠️ Warning: Don't take Redmi apart 6A If you have humidity above 60 percent or in a dusty room, the impact of dust particles on the motherboard can cause you to short-circuit the subsequent assembly.

Step-by-step: how to remove the back cover

The process of dismantling the Redmi 6A cover consists of 5 key steps. Follow them strictly in order to avoid missing important details.

Step 1. Heat the body.

The adhesive layer that holds the lid becomes elastic at a temperature of 50-60 ° C. Use a dryer at minimum power, evenly warming the back panel for 2-3 minutes. Keep the hair dryer at a distance of 10-15 cm so as not to overheat the battery.

Step 2: Separation of the cover

Put a plastic blade in the gap between the lid and the body at the charging connector. Carefully drive the tool along the edge, alternately snapping clips. Don't force - if the lid doesn't respond, warm it up again.

Step 3: Latching work

The Redmi 6A has 8 plastic latches: 2 on each side and 4 on the top (near the camera). The most fragile ones are the top! Separate the lid slowly, starting at the bottom edge. If you hear a crack, stop and check if the clip has broken.

Step 4: Disabling the battery plume

When you remove the lid, the first thing you do is unplug the battery plume (it's under a black protective film). Use the shoulder blade to gently lift the connector. Don't pull the wires!

⚠️ Warning: If the phone turns on accidentally after the battery is turned off (for example, due to a static discharge), this can burn the motherboard.

Step 5: Complete removal of the lid

Now you can remove the back panel completely. Notice the two adhesive tapes on the sides of the battery -- they also need to be carefully separated. If the tapes break, replace them with new ones when you reassemble them.

Common Mistakes and How to Avoid Them

Even experienced craftsmen sometimes make mistakes when disassembling the Redmi 6A. Here are the most common of them and ways to prevent them:

Another common problem is damage to the waterproofing gaskets. 6A They're placed around the volume and power buttons, and if the gasket breaks, the phone will lose its moisture protection (although it doesn't have an official one). IP-Replace it with a new one before assembly.

And many people forget about the antenna contacts on the back cover, which connect to the motherboard through spring connectors, and if you take them off, they can bend, which will cause the network signal to deteriorate.

1. whether the battery plume is connected (a common mistake is forgetting to connect it back).

2. Are there any foreign objects under the lid (screws, scraps of duct tape).

3. whether the antenna springs are properly installed (they should fit snugly to the contacts on the board).-->

What to do after removing the cover: further actions

Once the lid is successfully removed, you will be able to access the main components of the Redmi 6A.

• 🔋 Battery replacement is the most common cause of disassembly.Redmi 6A The battery is glued, so it must be carefully tucked and disconnected the plume before extraction.
• 📸 Camera Repair – If the module is not focusing or gives blurry pictures, check its plume and contacts on the board.
• 🔊 Cleaning speaker - dust and dirt often accumulate in the grille of the lower speaker. Use a soft brush or compressed air.
• 📶 Replacement of antenna module – if the phone is not catching the network well, the problem may be in the damaged antenna tracks on the lid.

1. Unscrew 4 screws that hold the metal frame of the screen.
2. Disconnect the plumes of the touchscreen and display (they are located under a black protective film).
3. Warm up the glue around the perimeter of the screen with a hairdryer (temperature 70 ° C) and gently tuck the display with a plastic card.

Replacing a charging connector or microphone would require a complete disassembly of the phone to the motherboard, which is more complex and requires experience — if you are not sure of your abilities, you should contact the service.

Before any part changes, always check their compatibility! For example, the battery for the Redmi 6A will not be suitable for the Redmi 6A due to different connectors.

Phone Assembly: How to Put Everything Back in Place

Reconstruction of the Redmi 6A is as much a process as disassembly. Here are the key points to pay attention to:

1. Checking latches and adhesive layer

If the plastic clips break, they can be replaced with similar ones from the repair kit (sold on AliExpress).The adhesive layer on the cover is better updated - use double-sided 3M 9448A Scotch (0.25 mm thick).

2. Connecting plumes

First, connect the battery plume, then the rest (fingerprint scanner, speaker, camera) make sure the connectors are snapped to the end, check the contacts for oxidation, clean them with a stripe if necessary.

Installation of the cover

Start at the top where the antenna contacts are located. Press the lid carefully so that all latches fall into place. Don't push too hard, fragile plastic can crack.

4. Post-assembly test

Before you turn the screws, turn on the phone and check:

• Does the touch screen work (are there any dead zones)?
• Do the volume and power buttons function?
• Is there sound in the speaker and microphone?
• Does the phone catch the network (check the signal indicator).

⚠️ Warning: If the phone overheats or discharges quickly after assembly, you may have damaged the heat paste on the processor, which should be replaced with a new one (e.g., Arctic). MX-4).

Alternative methods of disassembly (if nothing helps)

Sometimes the Redmi 6A lid doesn't respond even after warm-up and careful tweaking, and in these cases, you can try alternative ways:

Method 1: Use of thread

Drain a thin kapron thread (like guitar strings) between the lid and the body, carefully saw it with the adhesive layer, moving the thread back and forth, which requires patience, but minimizes the risk of damage to the latches.

Method 2: Screen suction cup

If the lid is a little bit off, but it's not completely removed, use a smartphone suction cup. Stick it to the center of the lid and pull it up while putting the edge on the shoulder blade, which works well if the glue is already softened.

Method 3: Disassembly through the screen

The last option is, if the lid is stuck dead, you can start disassembling from the front.

1. Warm up the screen with a hair dryer (70°C).
2. Push the display with a plastic card, starting from the corner.
3. Disconnect the screen plumes and remove the metal frame.
4. Get the motherboard - after that the cover is removed without obstacles.

This is a risky method, because it's very likely to damage the display or the plumes, and only use it if other methods have failed.
