How to open the back cover Xiaomi Redmi 6A: safe disassembly of the smartphone

The Xiaomi Redmi 6A is one of the brand’s most popular budget smartphones, but even it may need battery replacement, dust cleaning, or internal repairs over time. The main problem with self-repair is the risk of damaging the fragile back cover that attaches to the latches and adhesive layer. In this article, you’ll find detailed instructions with photos, video examples and life hacks on how to open the Redmi 6A case without scratches and cracks.

We'll take a look at three disassembly methods (with a mediator, a sucker, and no tools), tell you what mistakes lead to a latch break, and give you tips on how to choose tools, and you'll learn how to check the leakage after assembly, and what to do if the lid doesn't lock back, and if you've never taken a smartphone apart, don't worry: with the right approach, even a beginner can do it in 10 to 15 minutes.

Preparation for the disassembly: what will be needed

Before you start removing the lid, prepare the workspace and tools. Xiaomi Redmi 6A has a plastic case, but the latches are quite fragile - one careless movement can break them.

• 🔧 Plastic mediator (or guitar mediator) - for careful liding.
• 🧲 Suction (optional) - helps to evenly lift the cover without the risk of slipping.
• 🔥 Hair dryer or thermal air station - to soften the glue (if the cover does not lend itself to the adhesive).
• 📦 Container for screws – so as not to lose small parts (if you charge a fee).
• 🧴 Isopropyl alcohol (70%+) — glue-cleaner.

If you don't have special tools, you can do with a plastic card (for example, a discount card) or a toothpick, but the risk of damage to the case increases. Also prepare a soft fabric - it will come in handy to put the smartphone down with the screen and not scratch it.

Method 1: Opening the lid with a mediator (the safest)

This is a good way for most users to minimize the risk of damage, and the key is to be slow and effortless.

1. Turn off your smartphone and remove it. SIM-scatter-card.
2. Place the Redmi 6A screen down on a soft surface (such as a microfiber).
3. Start with the lower right corner (near the charging connector) - here the latches are weaker.
4. Carefully insert the mediator into the gap between the lid and the case and run it along the edge until you hear a characteristic click.
5. Repeat the procedure for the rest of the parties, without trying to immediately tear off the lid - it is held on 8-10 latches.

If the lid doesn't lend itself, don't force it -- it's likely the glue hasn't softened. In this case, use a hair dryer:

• 🔥 Heat the edges of the body for 30–40 seconds at minimum power (hold the hair dryer at a distance of 10–15 cm).
• ❄️ Let the plastic cool for 10 seconds – it will become more elastic.
• 🔄 Try again with the mediator.

Critical: On the Redmi 6A, the latches are asymmetrically positioned – they are thinner at the top (near the camera), so press less here.

Method 2: Use of suction cups (for experienced users)

Suctioning speeds up the process, but it requires precision and accuracy, and it's a good technique if you've already had experience disassembling gadgets.

1. Stick the suction cup to the central part of the lid (no closer than 1 cm to the edges).
2. Pull the sucker up smoothly, without jerks - a small gap should appear.
3. Insert a mediator into the formed gap and run them around the perimeter, freeing the latches.

⚠️ Attention: If the suction cup slips, it can scratch the lid or even break the screen. Do not use metal suction cups - only silicone or plastic.

💡

Before using the suction cup, slightly heat the cover with a hairdryer - this will increase the grip and reduce the risk of slipping.

This method is not suitable if:

• 🚫 The cover is already cracked or deformed.
• 🚫 There are severe scratches on the surface (suction cup will not hold).
• 🚫 You disassemble the smartphone in conditions of high humidity (suction cup will fall off).

Method 3: Untooling (emergency)

If you don't have a mediator or a sucker on hand, you can try opening the lid with your bare hands, but this is the riskiest way, only suitable for Redmi 6A with already weakened latches (for example, after previous disassemblies).

Instructions:

1. Lock the smartphone between the thumb and index finger behind the side edges.
2. With your thumbs, press the lower corners of the cover (near the USB connector), trying to "click" it.
3. As soon as there is a gap, put the lid on a nail or plastic card.

⚠️ Attention: This method breaks the latches in 60% of cases (according to statistics of service centers), if the smartphone is warranty or you plan to sell it, it is better not to risk it.

Frequent Mistakes and How to Avoid Them

Even with careful disassembly, users often make mistakes that cause latches to break, plumes to break, or leakage to lose, and the most common ones are:

Another common problem is that the lid doesn't come back down after assembly.

• 🔄 Deformed latches (need to be carefully aligned with tweezers).
• 🧴 Glue residues at the edges (remove with alcohol).
• 📱 Incorrectly stacked battery plume (check if it is squeezed over).

💡

If the phone doesn't turn on after assembly, it's likely that the battery or display has gone off, take it apart again and check all the connections.

What to do after a successful disassembly

When the finalmente lid is removed, don't rush to start repairing it.

1. Take a picture of the location of all the plumes and screws - this will help with the reverse assembly.
2. Check the integrity of the sealing gum (if any) – it protects against dust.
3. Clean the insides of the dust with a soft brush or a can of compressed air.

If you have disassembled a smartphone to replace the battery, consider:

• 🔋 The new battery should be the same capacity (3,000 mAh for Redmi) 6A).
• 🔌 Connect the battery plume last when all screws are swirled.
• ⚡ Calibrate the battery after replacement: fully discharge, then charge to 100% without interruptions.

If the purpose of disassembly is to clean up dust, pay attention to:

• 📸 Camera module (dust on the lenses worsens the quality of the photo).
• 🔊 Speaker and microphone (clogged with pile and particles).
• 📶 Antenna contacts (oxidation degrades network signal).

How to check the tightness after assembly

Once you've put the lid back in place, make sure it fits tightly.

1. Blow around the edges of the body - there should be no whistle (this is a sign of slits).
2. Shake your smartphone – you should not hear rattles (means that the screws are not twisted).
3. Turn on your smartphone and check it out: 📶 Network operation (if the antenna has departed, the signal will be weak). 🔋 Charging (if the battery plume is not connected, charging will not go). 📸 Camera (if the camera plume is clamped, there will be a black screen).

If the buttons are less responsive after assembly, it means that the lid is pressing on the mechanisms.

1. Remove the lid.
2. Check if a foreign object (for example, a piece of latch) has fallen under it.
3. Make sure the buttons are properly placed in the grooves.

💡

If the smartphone gets overheated after assembly, the heat on the processor is likely dry. Apply a new one (such as the Arctic MX-4) to normalize the temperature.
