Xiaomi Redmi Note 8 Pro is one of the most popular smartphones in the budget segment, but even it is not immune to breakdowns. Most often, users face the need to remove the back cover to replace the battery, repair the camera or clean up the dust. However, the design of the model has its own features: adhesive base, fragile latches and the risk of damage to the plumes. In this article, we will understand how to properly dismantle the cover, what tools you will need and how to avoid typical errors.
It's important to understand that disassembling your phone is insecure (if it's still in effect) and requires care. Even a little pressure in the wrong place can cause cracks in the glass panel or a break in flexible cables. If you've never disassembled a smartphone before, we recommend that you read the video instructions first or contact the service center. But if you decide to act on your own, follow our recommendations.
Training: tools and materials
Before you start disassembling, make sure you have everything you need, and not even one tool can make it difficult or damage.
- 🔧 Plastic mediators (2-3 - for gently putting the lid on. Metal tools can not be used, they scratch the body.
- 🔥 Hair dryer or thermo-air station for softening the glue. Optimal temperature: 60-80°C.
- 🧲 Suction cups (1-2 - Helps to lift the lid after heating. 3–5 centimeter.
- 📦 Screwdriver. T3 and T5 — for unscrewing screws inside the body (if deeper disassembly is required).
- 🧴 Isopropyl alcohol (90%+) — acetone or solvents should not be used!
- 📱 SIM card or tray – to block the power button when heated (see below).
Also, prepare your workspace: a table with good lighting, a soft substrate (like a silicone mat) and screw containers. If you plan to replace your battery or other components, order original parts in advance - fakes can fail in a few months.
⚠️ Warning: Do not use a household hair dryer at maximum power! The hot air flow can melt plastic elements inside the phone. The optimal distance from the hair dryer to the body is 5-10 cm, the temperature is not higher than 80 cm.°C.
Step-by-step instructions: how to remove the cover
The process of disassembling the Redmi Note 8 Pro consists of several steps, the main rule is to take your time and act consistently. Below is a step-by-step guide, taking into account the nuances of this model.
Step 1: Turn off and prepare the phone
Before disassembling, turn off your phone completely and remove the SIM cards from the tray. If the battery is swollen, do not turn on the device - it is dangerous! We also recommend removing the case (if any) and wipe the case from dust with a dry wipe.
Step 2: Heating the body
The Redmi Note 8 Pro cover is glued around the perimeter, so it needs to be softened.
- Insert a spare SIM card or tray into the SIM hole – this will block the on button and prevent accidental pressing.
- Heat the edge of the body with a hairdryer (not the center!) for 1-2 minutes, evenly driving the hairdryer around the perimeter.
- Check the temperature of the body with your hand - it should be warm, but not burning.
Step 3: Finishing the lid
After heating, gently attach the suction cup to the bottom of the phone (near the USB-C connector) and pull up slightly. If the lid doesn't lend itself, heat up for another 30 seconds.
Once a gap appears, insert a plastic mediator into it and slowly lead along the edge, separating the lid from the case. Be careful about the volume and on buttons - there are plumes!

Step 4: Disconnect the plumes (if necessary)
If you need to get to the motherboard or battery, after removing the lid, you will need to turn off the plumes:
- 📶 Battery plume - disconnects first (use a plastic shoulder blade).
- 📷 Camera plumes and fingerprint scanners are fragile, don’t pull the wires!
- 🔊 Dynamic plume - fastened on the latch, carefully lift it.
⚠️ Warning: If the phone doesn't turn on after the lid is removed, check if the battery plume has gone away. In 30% of cases, the "fault" after disassembly is due to poor battery contact.
Common Mistakes and How to Avoid Them
Even experienced craftsmen sometimes make mistakes when disassembling the Redmi Note 8 Pro. Here are the most common problems and ways to prevent them:
| Mistake. | Effects of consequences | How to avoid |
|---|---|---|
| Use of metal tools | Scratches on the body, damage to plumes | Use only plastic mediators |
| Overheating of the shell (>90°C) | Deformation of plastic, detachment of glass panel | Control the temperature with a thermometer or hand |
| Sharp compartment of the lid | Breaking the plume of the fingerprint scanner or camera | Grab the lid slowly, starting at the bottom edge |
| Pressing the centre of the cover | Cracks on the glass panel | Press only on the edges where the latches are located. |
| Ignoring glue residue | Poor fixation of the cover after assembly | Remove old glue with alcohol, apply new |
Pay special attention to the fingerprint scanner, which in the Redmi Note 8 Pro is built into the screen. If you accidentally pressed the display during disassembly, you may need to recalibrate the sensor (does in the security settings).

What to do if the lid is not removed?
Sometimes even after heating, the lid doesn't respond, and it can be related to:
- 🔥 Insufficient heating – try to increase the temperature to 85°C or extend the heating time.
- 🧴 Old glue - if the phone was operated in high humidity, the glue could "take" stronger.
- 🛠️ Deformation of the body - after falling, the latches can jam.
If the lid is not removed after 3-4 attempts, do not make excessive efforts! It is better to take a break for 10-15 minutes, let the glue cool, and then repeat the procedure. In extreme cases, you can use a thin guitar string (0.1-0.2 mm) to cut the glue around the perimeter, but this requires skill.

Assembly of the phone after repair
Once the repair is complete, you need to properly assemble the phone to avoid leakage and component problems.
- Check the plumes - all connectors should be tightly connected, without distortions.
- Clean the contacts - if there is old glue on the plumes or connectors, remove it with alcohol.
- Apply new glue – Use a thin layer of B-7000 or double-sided tape around the perimeter of the lid.
- Press the lid – after assembly, put the phone under the load (for example, a book) for 10-15 minutes.
- Check the functionality – turn on the phone and test the camera, fingerprint scanner, speakers.
If the phone does not turn on after assembly, check:
- 🔋 Connecting the battery (frequently the reason is a departed plume).
- 🔌 The on button contacts (may be contaminated or deformed).
- 📱 Integrity of flexible plumes (with a break will require soldering).
💡
If the fingerprint scanner doesn't work after assembly, try restarting your phone or resetting the sensor settings in the Settings menu → Passwords and security → fingerprints. 70% of the time, it helps.
When is the best time to contact the service?
Despite the fact that the dismantling of the Redmi Note 8 Pro is possible at home, in some cases it is better to trust the professionals:
- 💥 Bloated battery – the risk of fire if improperly removed.
- 📱 Cracks on the motherboard - soldering is required in an antistatic workplace.
- 🔧 Breakage of the charging connector - often associated with the separation of the contact platform.
- 💧 Fluid intake – ultrasonic cleaning and replacement of damaged components are necessary.
The average cost of dismantling in the service center is 500-1500 ₽, If you're in doubt about your skills, it's better not to take risks, because it's cheaper to repair than to replace damaged parts.
💡
The main rule when disassembling the Redmi Note 8 Pro is to take your time and use only plastic tools. Most breakdowns occur due to excessive effort or metal mediators.
