In this article you will find a step-by-step instruction taking into account the design features of Redmi. 6A, We will look at the tools you need (including budget-friendly ones) and the unique tips for preventing damage to plumes and latches, and we will look at both the classic suction cup and mediator method and the alternatives for those who don't have specialized tools. Special attention is paid to typical errors, due to which clips break or the screen is damaged.

Preparation for disassembly: tools and security measures

Before you start removing the lid, make sure you have everything you need. - Xiaomi Redmi 6A It is attached to a combination of glue and plastic latches, so without the right tools, the risk of damage to the body or internal components increases significantly.

Minimum set for safe disassembly:

  • πŸ”§ Plastic spatula (mediator) - required to separate the body without scratching!
  • 🧲 Suction cup (3-5 cm in diameter) - helps create the initial effort to detach the lid, will fit even from the old holder for the phone.
  • πŸ”₯ Hair dryer or thermo-air station - for softening the glue (temperature not higher than 60)Β°C to avoid damaging the battery!).
  • πŸ“¦ The screw container - at Redmi 6A They're not many, but they're easy to lose, and you can even have a plastic bottle lid with painted compartments.
  • 🧴 Isopropyl alcohol (70%+) β€” for cleaning glue residues and degreasing the surface before reassembling.

If you don’t have specialized tools, you can replace them:

  • πŸ’³ Instead of a mediator – an old bank card (cut corners so as not to scratch the case).
  • 🧊 Instead of a sucker - scotch 2-3 cm wide, glued cross-cross on the lid (pull at the ends at the same time).
  • β˜€οΈ Instead of a dryer – a heating pad or sunlight (put the phone on the heating battery for 5-10 minutes).

⚠️ Warning: Do not use knives, screwdrivers or other metal objects to lid!Even a slight pressure can lead to cracks in the plastic or damage to the plume of the touchscreen that runs along the left edge of the body.

Design of Xiaomi Redmi 6A: What you need to know before a demolition

Redmi 6A (The codename cactus has a typical design for Xiaomi budget smartphones: the back cover is attached to 8 plastic latches around the perimeter and a thin layer of glue:

  • πŸ”‹ The battery is glued - it does not need to be disconnected to remove the lid, but with sloppy movement, the connector can be damaged.
  • πŸ“Ά The antenna tapes are located on the upper and lower edges - they are easy to tear off if you pull the lid too sharply.
  • πŸ”Œ The touchscreen plume runs along the left side and is fixed by a metal frame!
  • 🎀 The microphone and speaker are fixed on the lid - they can be accidentally torn off if you do not monitor the effort.

Unlike the flagship models, the Redmi 6A There's no waterproof seal, so the lid is relatively easy to remove, but plastic latches become brittle over time -- if you've taken the phone out before, be extra careful.

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

Follow this algorithm to minimize the risks, and it'll take 10 to 15 minutes if you're properly prepared.

Step 1: Turn off and heat your phone

Before disassembling, be sure to turn off Redmi 6A (press the power button and select Turn it off:

  1. Put the phone down on a flat surface.
  2. Heat the back cover with a hairdryer for 1-2 minutes, keeping it at a distance of 5-7 cm.
  3. Check the temperature with your hand – the cover should be warm, but not hot.

Step 2: Creating an initial gap

Apply the suction cup to the bottom of the lid (near the Micro-USB connector) and pull up. If there is no suction cup:

  1. Put the cross-cotch tape on the lid.
  2. Pull all four ends at the same time, creating a uniform effort.

As soon as there is a gap (even 1-2 mm), insert a mediator into it.

Step 3: Separating the lid around the perimeter

Carefully drive the mediator along the edge of the body, starting at the bottom.

  • ➑️ Walk on the right side (there are no plumes, the risk is minimal).
  • ⬆️ Go up to the top edge where the volume and power buttons are. Be careful, there's antenna tapes going through!
  • ⬅️ The left side is the most dangerous. Don't push hard so you don't damage the touchscreen plume.

β˜‘οΈ Check before full removal of the cover

Done: 0 / 4

Step 4: Complete removal of the lid

When all latches are disconnected, carefully lift the lid from the bottom side at an angle of 30-45.Β°. Don't pull it too hard, there may be some glued areas inside, if the lid doesn't lend itself:

  • Check if there are any unclicked clips left (usually in the upper corners).
  • Warm up the problem area with a hairdryer again.
  • Use the second mediator to distribute the effort evenly.

⚠️ Warning: If after removing the lid you see that the plume of the touchscreen has moved away from the connector, do not try to insert it back yourself - this requires a special tool (tweezers with plastic tips) and experience.

πŸ’‘

If the lid is not attached to the latches after removal, check their integrity. Often the problem is the deformed clips - they can be carefully straightened with tweezers, heating the hair dryer for plasticity.

What to do if the cover is not removed

Sometimes even after heating and using the suction cup, the Redmi cover 6A It's not amenable. Causes and solutions:

Problem.Possible causeDecision
The cover does not move even after heating.Too much glue (maybe the phone has already been repaired)Increase the heating time to 3-4 minutes or use a more powerful hair dryer
The slit appears, but the lid is not completely removed.There are unclicked clips (usually in the upper corners)Walk the mediator again, paying attention to the corners
Suction's not holding.The surface of the cover is contaminated or scratchedRub the lid with alcohol and try pasting scotch instead of suction cup
The lid cracked when it was removed.Use of a metal tool or excessive forceYou'll have to replace the lid. Use Scotch for a temporary solution.

If none of the methods worked, it is possible that the lid was glued to a double-sided high-strength tape (for example, after a previous repair).

  1. Heat the case to 60-70Β°C (carefully so as not to damage the battery!).
  2. Use a thin guitar string or fishing line (0.2–0.3 mm) to cut the glue around the perimeter.
  3. Movements should be sawing, without pressing on the body.

This method requires patience, but it is the most effective for "stick-to-stick" covers.

Reverse Assembly: How to properly install the cover back

Putting the lid back in often raises more questions than removing it. The main rule is, don't press the center of the lid, it can damage the internal components.

  1. Clean the surfaces of glue and dust residues with isopropyl alcohol and a lilac-free wipe.
  2. Check the latches on the lid and body – they should be whole and not deformed.
  3. Line the cover on the Micro-USB connector and buttons (they should match the cutouts).
  4. Push the edges around the perimeter, starting at the bottom, and you'll hear clicks, and the clips will click.
  5. Check the density of the fit: if the cover is wobbling, then not all latches are fixed.

If the cover is not held tightly, double-sided scotch (for example, can be used, 3M 467MP or 3M 468MP). Stick it in thin strips around the perimeter of the case, avoiding areas near connectors and buttons. Do not use superglue or other aggressive adhesives - they can damage the plastic or make the next disassembly impossible.

⚠️ Warning: After assembly, turn on the phone and check the operability of all components: πŸ”Š Speaker and microphone (record voice note). πŸ“Ά Antenna (check the signal level of the network). πŸ”‹ Charging (plug the cable and make sure the phone detects charging). πŸ‘† Touchscreen (swipe your finger all over the screen) If something doesn't work, it means that the plume or connector was damaged during the disassembly.

πŸ’‘

If the phone doesn't turn on after assembly, don't panic! First check if the battery connector has moved away (it could have shifted when the lid was installed).

Alternative methods of removing the lid without tools

If you don't have a sucker, a mediator or a hair dryer, you can try using the tools you can use, which are less reliable, but in an emergency, you can use them to:

Method 1: Scotch + credit card

  1. Stick a wide cross-cotch tape onto the back cover.
  2. Heat your phone by putting it on a heating battery or under a lamp for 10 minutes.
  3. Pull all four ends of the tape at the same time, creating a uniform effort.
  4. Once a gap appears, insert a cropped credit card and guide it around the perimeter.

Method 2: Dental floss

Thin dental floss (better waxed) can replace the mediator:

  1. Push the thread into the gap between the lid and the case (start with the Micro-USB connector).
  2. Move the "saw" walk along the perimeter, gradually deepening the thread.
  3. Do not pull the thread at an angle - only parallel to the body!

Method 3: Disassembly through the screen (extreme case)

If the lid is categorically not removed, and the phone is no longer on warranty, you can go from the opposite:

  1. Remove the screen (it is attached to latches and glue, but usually comes off easier than the cover).
  2. Disconnect the screen and battery plumes.
  3. Get the motherboard out - after that the lid is removed without effort.

This method is risky and only suitable for experienced users!

If you're taking Redmi down 6A to replace the battery, after removing the lid do not rush to tear off the old battery - first disconnect its connector from the motherboard!

Frequent Mistakes and How to Avoid Them

Even with careful disassembly, you can make mistakes that will lead to breakdown, and here are the most common ones and ways to prevent them:

  • πŸ”¨ Using metal tools -- scratches the body and can close contacts on the board. Solution: Wrap the screwdriver with tape or use a plastic blade.
  • πŸ”₯ Overheating of the body - temperature above 70Β°C deforms the plastic and damages the battery. Solution: Heat the lid to a warm state (not hot!) and take breaks.
  • πŸ’₯ Sharp lid, rips antenna tapes and plumes. Solution: Move the mediator smoothly, without jerking.
  • πŸ”‹ Forgetting to disconnect the battery before working with the board. Solution: Always turn off the battery first thing, even if you just take the lid off.
  • 🧩 Loss of screws at Redmi 6A Solution: Use a magnetic mat or a container with compartments.

Another common mistake is to put the lid back incorrectly, so if the latches don't click, don't push the lid down, check their position again, and correct them with tweezers if necessary.
