Xiaomi Redmi Note 8 Pro is one of the most popular smartphones in the budget segment, but its maintainability leaves much to be desired. The back of the device is glued to the body, not fixed with screws, as in older models. This makes it difficult to access the battery, speaker or camera. In this article, we will discuss how to open the cover of the Redmi Note 8 Pro without damage, what tools you will need and what to look for to avoid turning a smartphone into a brick.
The procedure requires care: the wrong exposure can lead to cracks in the glass, damage to the plumes or tearing off the antenna contacts. We collected proven methods from the masters of service centers, and added video instructions and a table with alternative methods. If you have never disassembled smartphones, you better go to the professionals. But if you decide to act on your own, follow our recommendations.
Preparation for disassembly: tools and security measures
Before you open the Redmi Note 8 Pro cover, prepare the workspace and tools.
- 🔧 Plastic mediator or guitar mediator (thickness 0.3–0.5 mm) – for separation of the cover.
- 🔥 A building (or powerful household) hair dryer – to soften glue.
- 🧲 Suction cup (better with a ring) - to lid the lid after heating.
- ⚙️ Screwdriver. T3 — screw-off.
- 📦 Plastic tray - for storing small parts.
Also, stock up on isopropyl alcohol (90%+) to help remove glue residues after disassembly. Never use metal tools (knives, screwdrivers) to slap the lid, guaranteed to result in scratches or cracks on the glass. If you don't have a hair dryer, alternative heating methods (discussed below) are less effective.
⚠️ Warning: Heating of the smartphone over 60°C can damage the battery. Don't direct hot air to the screen or camera -- just around the perimeter of the back cover.
Before starting work, turn off the smartphone and remove SIM-If the battery is swelling, you should trust the technicians to disassemble it, because the risk of short circuit or fire is too high, and check if the warranty is expired: self-opening the case will void it.
Step-by-step: how to open the lid without damage
The most reliable way is to heat the adhesive layer and then carefully undercoat the lid.
- Heat the body. Set the hair dryer at 50 to 60°C and warm the back cover evenly around the perimeter for 3 to 5 minutes. Keep the hair dryer at a distance of 5 to 7 cm to avoid overheating the plastic.
- Put the lid on. Suction the suction cup onto the top of the lid (near the headphone jack) and pull up. Insert a plastic mediator into the slit.
- Walk around the perimeter. Carefully use a mediator along the edge of the lid, separating it from the body. Take your time, the glue may be unevenly softened.
- Remove the lid. When the mediator passes through the perimeter, the lid will be removed effortlessly, and if you feel resistance, reheat the problem area.
Once you remove the lid, you'll see 12 T3 screws that attach the metal plate. Don't unscrew them right away, first disconnect the battery plume to avoid short circuit, and then you can apply a plastic blade to the black connector on the motherboard.

⚠️ Warning: If the lid doesn't respond to heat, don't use excessive force. The glue may not have softened enough. Reheat for another 2-3 minutes, paying attention to the "stubborn" areas (usually the corners near the camera).
Alternative ways to open the lid (without a hair dryer)
If you don't have a hair dryer, you can use other methods of softening the glue, but they're less effective and require more care.
| Method | Advantages | Deficiencies | Heat time |
|---|---|---|---|
| Warmer or warm water | Available at home | Risk of moisture, uneven heating | 10-15 minutes |
| Iron through fabric | Heats up large areas well. | It's hard to control temperature. | 5-7 minutes |
| Hot air from the oven | Uniform heating | Risk of overheating, it is inconvenient to fix the smartphone | 8-10 minutes |
| Chemical solvents (alcohol, acetone) | Softens the glue without heating | May damage plastic or rubber seals | 15-20 minutes |
When using chemical solvents, apply them only on the seam between the lid and the body with a cotton swab. Isopropyl alcohol is safer than acetone, but acts more slowly. After applying any solvent, thoroughly wipe the body with a dry wipe.

Frequent Mistakes and How to Avoid Them
Even experienced users sometimes make mistakes when disassembling the Redmi Note 8 Pro.
- 🔋 The battery was not turned off before work, which can lead to short circuits when contacts accidentally close.
- 📸 The camera plume has been damaged. It's very fragile -- don't pull it or bend it.
- 🔊 They've cut off the antenna contacts, they're glued to the lid, and they come off easily when you're not taking them off.
- 🔩 We've got screws mixed up in the build. The Redmi Note 8 Pro uses screws of different lengths -- remember which ones you're going to get from.
To avoid problems, take a picture of each stage of disassembly, especially the location of the plumes and screws. If you remove the cover to replace the battery, pay attention to the adhesive tape underneath - it must be carefully removed so as not to damage the charging controller.
1. Is the battery plume connected?
2. Are the contacts closed on the motherboard?
3. whether the metal plate is properly installed (it must fit snugly to the body).-->
What to do after the successful opening of the lid?
When the lid is removed, you will have access to the main components of the Redmi Note 8 Pro:
- 🔋 Battery (capacity 4500 mAh, article) MB-EU-BATRZM-01).
- 📸 Main camera (4 modules: 64 MP) + 8 MP + 2 MPs + 2 MPs).
- 🔊 Speaker and microphone (located at the bottom of the microphone).
- 📶 Antenna modules (stick to the cover).
If the purpose of disassembly is to replace the battery, remember: the new battery must be original or from a proven manufacturer (for example, ZMI or Baseus). Cheap analogues can swell or not hold a charge. After replacing, be sure to calibrate the battery: completely discharge the smartphone, then charge to 100% without interruption.
To clean your guts of dust, use a soft brush or a spray of compressed air. Don't blow with your mouth, the moisture from your breath may settle on the board. If you notice corrosion on your contacts, clean them with a blower or alcohol.

After any disassembly, check the tightness of the case.Redmi Note 8 Pro has no official water protection (IP-The seals around the perimeter of the lid prevent dust from entering, if they are damaged, replace them or apply a thin layer of silicone lubricant.
Smartphone Assembly: How to Stick the Cover Back
Putting the Redmi Note 8 Pro back together is harder than disassembling, and the main challenge is to ensure that the lid is evenly glued to avoid slits.
- Clean the edge of the case and cover of the old glue with isopropyl alcohol.
- Apply the new adhesive (B-7000 or double-sided 3M 9448A) with a thin layer around the perimeter.
- Carefully combine the cover with the body, starting with the headphone jack.
- Tightly press the lid and fix it with rods or heavy books for 10-12 hours.
Don't turn on the smartphone right after assembly -- let the glue dry completely. If the lid is still going away after gluing, it's not uniformly applied, and then you'll have to repeat the procedure.
⚠️ Warning: Do not use superglue or Moment glue - they can damage the plastic and make subsequent disassembly impossible. Also avoid glue with aggressive solvents (such as cyanoacrylate), as it can leak inside and damage the plumes.
