Xiaomi Redmi 6 Pro is a popular smartphone of 2018, which is still used by many users. However, over time, it may require a replacement battery, speaker or even camera, and this requires removing the back cover. Unlike today's flagships with adhesive panels, the disassembly of this model has its own nuances: it combines latches, glue and brittle plumes.
This article will help you understand how to properly remove the lid without damage. We will look at the necessary tools, detailed sequence of actions, as well as common errors that lead to a fingerprint break or the rupture of flexible cables.
Preparation for disassembly: tools and security measures
Before you start removing the lid, make sure you have everything you need. The wrong tool is the main cause of chipping plastic or scratching a metal frame.
- 🔧 Plastic blade (preferably a set with different thicknesses - 0.2 mm, 0.4 mm and 0.6 mm!
- 🔥 A dryer or a thermo-air station (at least 800 watts) for softening the adhesive. Temperature: 70-90°C.
- 🧲 Suction cup (diameter 4-5 cm) for initial lid suction. Alternative - double-sided tape.
- 📦 A screw container (or magnetic mat) to avoid losing small parts.
- 🔍 Loop or magnifying glass for inspection of latches and plumes.
Also, prepare your workspace: a clean surface (better with a soft substrate), good lighting and an antistatic bracelet if you plan to work with a board. Don't disassemble your phone on a carpet or couch - static electricity can damage chips!
⚠️ Warning: If the phone has been in water or hit, disassembly may result in short circuits due to oxidized contacts.In this case, first dry the device in rice or silica gel for at least 48 hours.
Step-by-step: how to remove the cover from the Redmi 6 Pro
The process of removing the lid is divided into 3 stages: heating the glue, separation of latches and careful tweaking.
- Turn off the phone and remove it. SIM-You don't have to turn off the battery, it's done later.
- Warm up the adhesive around the lid with a hairdryer for 2-3 minutes. Keep the device 10-15 cm away so that the display does not overheat. Pay special attention to the corners and areas near the USB-C connector.
- Suction or tape, grab the bottom of the lid (near the speaker) and pull up. If the lid doesn't lend itself, reheat the problem area.
- Insert a plastic blade into the gap and slowly lead it along the body, snapping the mounts. Start at the lower left corner, there are fewer plumes.
The hardest part is the top of the lid, where the fingerprint scanner and the camera plumes go, and you can't use force here, if you feel resistance, check if all the latches are snapped. Redmi 6 Pro has 12 latches, 3 on each side and 6 on the perimeter.

When the lid is detached, don't remove it completely -- it's still connected by a flexible fingerprint scanner plume. Carefully lift and put aside, fixing the plume so that it doesn't break.
⚠️ Warning: If you see a bloated battery after removing the lid (it will be convex or white), immediately stop disassembling! This battery can not be pierced or bent - the risk of fire!
Hidden latches and typical errors in disassembly
The main problem with the Redmi 6 Pro is that it's invisible latches that are easy to miss.
- 🔹 The top right corner is next to the antenna plume, and the plastic fixture often breaks down here.
- 🔹 The bottom of the connector. USB-C — The most powerful latch that many forget to crack.
- 🔹 Left edge near volume buttons - here the plume of the fingerprint scanner is glued to the cover.
Typical Beginner Mistakes:
| Mistake. | Effects of consequences | How to avoid |
|---|---|---|
| Use of metal tools | Scratches on the body, damage to plumes | Only plastic blades with rounded edges |
| Overheating by a hairdryer (>100°C) | Display detachment, plastic melting | Keep your hair dryer at a distance, use a thermometer |
| The lid's jittery. | Fracture of the fingerprint scanner plume | Slowly drive the shoulder blade, checking resistance |
| Disassembly without battery shutdown | Short circuit when touching the board | Disconnect the battery immediately after removing the lid |
If you find that the fingerprint scanner is not working after you take off the cover, it's likely that the plume has broken off, and you'll need to solder it or replace the module. The service center charges you between 1,500 and 2,500. ₽.
💡
Before disassembling, take a picture of the location of all the plumes and screws, which will help to properly assemble the phone back, especially if the process is delayed for several days.
What to do after removing the cover: further actions
Once the lid is successfully dismantled, you'll have access to the internal components.
- 🔋 Replacing the battery is the most common cause of disassembly. In the Redmi 6 Pro, the battery is glued, so it needs to be carefully tucked in and disconnect the power plume.
- 📷 Cleaning or changing the camera. Dust on the module often causes blurred photos. Use a lilaless napkin and alcohol.
- 🔊 Repair speaker or microphone. In this model, the speaker is mounted on two screws, and the microphone is mounted on glue.
- 📡 Replacement of the antenna module (if the network signal is missing) Requires soldering or replacement of the flexible cable.
If your goal is to replace the display, then after removing the cover you need:
- Disconnect the battery (disconnect the plume from the motherboard).
- Heat the screen around the perimeter with a hairdryer (60-70 ° C).
- Substitute the screen with a plastic spatula, starting at the bottom edge.
- Disconnect the display plume and touchscreen (they go separately!).
The main rule is to check all the plumes for integrity before the final fixation of the lid. If the phone does not turn on after assembly, there is likely a problem in the battery connector or the display plume.

Alternative ways to remove the cover (if nothing helps)
Sometimes the Redmi 6 Pro lid gets so tight that standard methods don't work, so you can try alternative approaches.
- 🧊 Cooling method: Put your phone in the freezer for 10 to 15 minutes. The glue will become brittle, and the lid will move away easier.
- 🧴 Special solvents (e.g. 99% isopropyl alcohol) Apply a few drops around the perimeter and wait 5 minutes. The glue will soften, but there may be a sticky trail.
- 🔪 Nichrome thread (for the experienced) Heated thread melts the glue, but requires precision - you can damage the plumes.
If you decide to use a solvent, remember:
⚠️ Attention: Alcohol or acetone should not be on the display, they corrode the oleophobic coating. Apply the liquid only to the end of the lid with a syringe.
As a last resort, if the lid is not amenable and the phone is not guaranteed, you can contact the service. The average cost of dismantling the Redmi 6 Pro in workshops is 500-1000. ₽. However, please note that some services disclaim responsibility for damages caused by previous repair attempts.
How to avoid damage when assembling back
It's often harder to assemble a phone than to disassemble it, and here are the key points to consider:
- Check all the latches, they should click clearly when the lid is closed. If the latches are broken, the lid will dangle.
- Make sure the plumes are not twisted, especially with the fingerprint scanner and the camera.
- Apply a new glue (e.g., B-7000) around the perimeter of the lid for tightness. Without glue, the phone will lose its dust protection.
- Check the buttons, they should be pressed with a characteristic click, and if the button falls, it means that it has got garbage under it or it is set curved.
After assembly, turn on the phone and check:
- 📶 Network operation (calls, mobile Internet).
- 🔋 Charging (plug the cable and make sure the current is going on).
- 📸 Camera and fingerprint scanner.
- 🔊 Speaker and microphone (record voice message).
If something's not working, don't panic. Maybe the train has gone off. Take the phone apart again and check all the connections. 80 percent of the time, the problem is solved by reassembling.
💡
The key is to take your time, and even experienced craftsmen spend up to 20 to 30 minutes checking the plumes and latches to avoid re-disassembly.
When the disassembly is inappropriate: signs of serious breakdowns
It's not always worth it to repair yourself, but here are some of the best times to go to the service or buy a new phone:
- 💥 A bloated battery with a white coating on the board is a sign of electrolyte leakage. It requires a complete cleaning and replacement of the battery with a check of the power chains.
- 🔥 Scorched chips on the motherboard (black spots, the smell of burning) means short circuits, and repairs will cost more than a new phone.
- 💧 Traces of corrosion after water hits, and even if the phone turns on, oxidation will eventually lead to more breakdowns.
- 📱 A crack on the motherboard, usually after a fall, repairs are only possible with a replacement board, which is not cost-effective.
If you notice any of these signs, estimate the cost of repair. For the Redmi 6 Pro, a critical amount is more than 5000-6000. ₽ — In this case, it is more profitable to buy a used phone of the same model or a new budget model Xiaomi.
Remember: self-repair will void the warranty (if it is still valid) and check the serial number warranty status on mi.com before disassembling.
