Disassembly Xiaomi Redmi 6A: a complete analysis with photos and repair tips

Xiaomi Redmi 6A is one of the most popular budget smartphones of 2018, which is still in active use. However, over time, even such reliable equipment requires repairs, from replacing the battery to cleaning the connectors. You can disassemble the Redmi 6A yourself, but the process has nuances that you need to know about in advance.

In this article, you'll find a step-by-step photo guide, a list of tools you need, and unique tips for disassembling without damaging the plumes and body. We'll figure out how to properly remove the back cover, disconnect the battery, and get to the motherboard without damaging fragile elements. If you've never taken your smartphones apart, this guide will help you avoid typical mistakes.

Preparation for disassembly: tools and security measures

Before you start disassembling the Xiaomi Redmi 6A, make sure you have everything you need. Inappropriate tools are the main cause of damage to the body or internal components.

  • πŸ”§ Plastic blades (mediators) - for careful slashing of the lid and plumes.
  • ⚑ Screwdriver cross (PH00) β€” for the screws of the case and motherboard.
  • πŸ”‹ Screen suction cup - will help remove the back cover without scratches.
  • 🧲 Magnetic mat or container – to avoid losing small screws.
  • πŸ“± Hair dryer or thermoplatform - for softening the glue (optional, but useful).

Also prepare a clean workspace with good lighting. Redmi 6A has brittle plumes, so try not to work on a carpet or soft surface - static electricity can damage the board. If you disassemble a phone to replace the battery, completely discharge it before work begins: this will reduce the risk of short circuit.

⚠️ Warning: Do not use metal blades or knives to jack the lid! 6A It's made of plastic that's easy to scratch or break, and plastic mediators are safer and more efficient.

πŸ“Š You’ve already taken out smartphones before?
Yes, many times.

Step 1: Removing the back cover - how not to break the latches

The back cover of the Xiaomi Redmi 6A is mounted on plastic latches and a thin layer of glue. To remove it, start at the bottom edge (near the charging connector). Put the suction cup to the center of the lid and pull it up slightly. If the lid doesn't lend itself, gently apply it with a plastic blade as you move around the perimeter.

Pay special attention to the corners, where the most fragile latches are located. If you hear a crack, stop immediately: you are probably pushing too hard. It is better to warm the lid with a hair dryer (temperature ~ 60 Β° C) for 1-2 minutes, this will soften the glue and facilitate the process.

Warm up the back panel with a hairdryer (optional)

Attach the suction cup to the center of the lid

Carefully pull up, starting from the bottom edge

Push plastic blade around the perimeter, avoiding corners

Check if all latches are snapped before removing the lid completely-->

When you take the lid off, you'll see the battery glued to the case. Don't try to pull it out right away, you'll need to disconnect the power plume from the motherboard first. Notice the black film under the battery, which protects the board from accidental circuits. Don't hurt it!

Step 2: Battery Disconnection – Why It’s Critical to Do It First

The battery in the Redmi 6A is the most dangerous component in disassembly, and if it's not turned off, accidental closure of the contacts can disable the motherboard.

  1. Find the white power connector on the board (usually located near the bottom edge).
  2. Carefully slap the connector with a plastic spatula, pulling up. Don't use metal tools!
  3. Make sure the connector contacts are not bent or oxidized. If there is corrosion, clean them with alcohol.

Once the battery is turned off, you can start removing the motherboard, but remember, not all plumes are equally strong, for example, the camera plume and the fingerprint sensor (if you have one in your version) are extremely thin and easily break when you handle it carelessly.

⚠️ Note: If you are looking for Redmi 6A If you want to replace your battery, don't rush to pull out the old one right after you shut it down.

Step 3: Motherboard Removal – Where the β€œpitfalls” are Hidden

The Xiaomi Redmi 6A motherboard is mounted on 8-10 screws of varying lengths. Remember their location, the screws must fall into place when you assemble them, otherwise the board may warp. Start by unscrewing all visible mounts, then carefully raise the board with a shoulder blade.

Pay attention to the following nuances:

  • πŸ“Ά The antenna contacts (at the top of the board) bend easily. Don't pull a fee for this edge.
  • πŸ”Œ The display and sensor plumes are glued to the board, and they need to be disconnected after the board is raised. 1-2 mm.
  • πŸ”Š The speaker and microphone can stay in the case - do not pull them by force.

If the board fails, check if all the screws are screwed out. Sometimes the manufacturer hides one screw under a sticker or under a battery. 6A This type of screw can be under SIM-ATLANTE: Don’t forget to check it out!

Take a picture of the screws and plumes before removing the board, which will make it much easier to reverse assemble, especially if you are a beginner.

Step 4: Disassemble the screen when it’s really necessary

In most cases, you don't need to disassemble the Xiaomi Redmi 6A screen -- you just need to remove the motherboard to access most of the components, but if you need to replace the display, touchscreen or front camera, you'll have to go further.

The screen in Redmi 6A is glued around the perimeter, and to remove it you will need:

  1. Warm up the edge of the screen with a hair dryer (temperature ~70 Β° C) for 2-3 minutes.
  2. Substitute the screen with a plastic spatula, starting from the lower right corner (there are fewer plumes).
  3. Carefully separate the screen from the body, do not pull it completely - first disconnect the plumes!

⚠️ Attention: Display plume in Redmi 6A It's extremely fragile. If you tear it, the screen will stop working even if the display itself is intact.

If the goal is to replace the touchscreen, consider that the Redmi 6A has it glued to the display, and it's almost impossible to separate them without special equipment, so it's easier to buy a prefabricated module (display + touchscreen).

What to do if the screen does not separate?
If the screen still fails to warm up, try the following steps: 1. Increase the temperature of the hair dryer to 80Β°C (but not higher so as not to damage the plastic). 2. Use a thin guitar string or a special thread to cut the glue. 3. Check if there are untwisted screws left under the stickers or in the corners of the case. If nothing helps, it is better to contact the service - forced separation of the screen can lead to cracks or damage the plumes.

Step 5: Replacing the battery – how to avoid mistakes

The battery in Xiaomi Redmi 6A (BYD DM-43 or ATL DM-42) loses capacity over time, and replacing it is one of the most common reasons for disassembly. The new battery must be the same model, otherwise it may have problems with charging or working the smartphone.

Replacement process:

  • πŸ”‹ After the power plume is turned off, gently tuck the battery into a plastic spatula. It's glued, so act slowly.
  • 🧴 If the glue is too sticky, drop a little isopropyl alcohol under the battery - this will help separate it.
  • πŸ”„ Install a new battery, making sure the contacts match the connector on the board.

After you change the battery, don't turn the phone on immediately. First, assemble it completely, then charge it to at least 20%, which will help calibrate the power controller. If the new battery doesn't hold the charge, check if the power plume is connected correctly and if there is no swelling on the battery itself.

When buying a new battery for the Redmi 6A, pay attention to the production date. A battery that has been in storage for more than a year can already lose up to 20% of its capacity.

Building a phone: how to avoid typical mistakes

Building a Xiaomi Redmi 6A after disassembly is often harder than disassembling, and the rule of thumb is to do the reverse, from the motherboard to the back cover.

  • πŸ”© The screws have to fit in. If a screw doesn't screw in, don't push it. You're probably confusing it with another screw.
  • πŸ“Ά The antenna contacts on the board must fit tightly to the body, otherwise the network signal will deteriorate.
  • πŸ”‹ The battery plume should be connected last, before installing the cover.
  • 🧱 The lid latches should click when pressed. If the lid is dangling, check if all the latches are in place.

After assembly, turn on the phone and check:

  1. Does the touchscreen work (are there no dead zones)?
  2. Is the battery charged (the indicator should be on fire)
  3. Does the speaker, microphone and cameras work?

If something doesn't work, take the phone apart again and check the plumes are connected, and most often, problems arise from a poorly inserted display or battery connector.

FAQ: Frequent questions about the Xiaomi Redmi 6A disassembly

Can you make Redmi 6A without a hairdryer?
Yes, but it's more complicated. Without heating, the adhesives on the lid and battery will not go away well, which increases the risk of damage to the latches. If the hair dryer is not, use hot water in the bag (attach to the lid for 1-2 minutes) or work very carefully with plastic blades.
What if the phone does not turn on after assembly?
There could be several reasons: πŸ”Œ Not connected battery plume or display. πŸ”‹ The battery is defective or incorrectly installed. πŸ“± The motherboard is damaged (e.g. static electricity) Take the phone apart again and check all connections. If the board is damaged, you will need a diagnostic in the service.
What kind of adhesive should I use for the battery when replacing?
Better use 3M double-sided tape or special battery glue (like the B-7000) and don't put too much glue on it, it'll make it harder to disassemble the next one.
Can you replace the entire screen, not the entire module?
Technically possible, but extremely difficult. In the Redmi 6A, glass is glued to a display and touchscreen, and separation requires special equipment (laminator, UV glue) and it is easier and cheaper to replace the entire module at home.
Where to buy parts for Redmi 6A?
Parts can be found on: πŸ›’ AliExpress (cheap but longer delivery). 🏬 Local service centers (expensive but faster). 🌍 Sites like eBay or Amazon (there are original and unoriginal details) When buying a battery or screen, check for compatibility with the model. M1804C3DG (global version) or M1804C3DC (Chinese).
