Xiaomi Redmi Note 8 Pro is a popular smartphone with a durable metal body and glass back, but even it is not immune to breakdowns. Battery replacement, camera repair or dust cleaning require removal of the lid, and wrong actions can lead to screen cracks or damage to plumes. This article will help you understand how to properly dismantle the rear panel without specialized tools (or with a minimum set), which pitfalls await beginners and how to avoid typical errors.
It's important to understand that the design of the Redmi Note 8 Pro is different from the budget models of Xiaomi, it uses perimeter duct tape + latches, not just clips, as in plastic cases. This complicates the process, but with the right approach, the lid is removed in 10-15 minutes. We will analyze two methods, using a suction cup and a mediator, and an alternative method for those who do not have professional tools.
Preparation: what will be needed for the disassembly
Before you start, make sure you have everything you need, and not even one tool can turn a simple procedure into a nightmare with broken glass or broken plumes.
- π§ Plastic mediator (or guitar mediator) β for separation of the body without scratches.
- π§² Suction cup (better with a metal ring) - helps to suction the lid evenly.
- π₯ Hair dryer or heat gun - softens the glue (temperature 60-80)Β°C).
- β‘ Screwdriver. T3 or T4 β screw-off.
- π¦ Container for screws - so as not to lose small details.
If you don't have a suction cup, you can replace it with a flat screwdriver with a seal on the tip (so you don't scratch the body), and instead of a hairdryer, hot water in a plastic bag will work, you can put it on the back for 2-3 minutes. The main thing is not to overheat: at temperatures above 90 Β° C, the glue can dry even more.
Step-by-step: remove the cover with a suction cup and a mediator
This method is considered the safest for the Redmi Note 8 Pro, as it minimizes the risk of glass damage.
- Turn off the phone and remove it. SIM-The battery should be charged no more than 30 percent, which will reduce the risk of fire in the event of an accidental circuit.
- Heat the edges of the body with a hair dryer for 1-2 minutes, holding it at a distance of 5-7 cm. Pay special attention to the area near the buttons and the USB-C connector - there the glue usually holds stronger.
- Stick the suction cup closer to the bottom edge (where the charging connector is) and press it to fit tightly.
- Pull the suction cup up with moderate force while inserting the mediator into the resulting slit. Don't pull too hard - the glass may crack!
- Swipe the mediator around the perimeter, gradually separating the lid. At the corners and near the buttons, you do not need to bend the mediator - it is better to carefully cut back and forth.
If the lid doesn't lend itself, reheat the problem area. Don't try to tear it away by force, it will break the fingerprint scanner plume (it goes from the back to the motherboard). In the Redmi Note 8 Pro, this plume is especially fragile!
βοΈ Checklist before lid removal
Alternative method: without suction cup and hair dryer
If you don't have tools, you can do with the tools you need, but you're at a higher risk of damage.
- Stick tape to the back of the cross-over, leaving the corners free, which will help hold the shrapnel if the glass cracks.
- Insert a plastic card (for example, a credit card) into the gap between the lid and the case at the USB-C connector. Carefully drive it along the edge, trying to "click" the clamps.
- Repeat the process for all sides, lifting the lid a little bit. If you hear a crunch, stop immediately!
This is only suitable for emergencies. Without heating, the glue remains strong, and there is a great chance of breaking the plume of the fingerprint sensor or damaging the antenna contacts (they are located on the sides of the case). If the lid does not respond after 3-4 attempts, you better use a hair dryer or contact the service.
β οΈ Warning: Never use metal objects (knives, screwdrivers) to lash the lid! Even a small scratch on an aluminum frame can become a hotbed of corrosion, and Gorilla Glass 5 glass cracks with a probability of 80 under uneven pressure%.
What to do after removing the cover: the first steps
When the lid is finally separated, don't be too quick to put it aside.
- πΈ Take a picture of the location of the plumes β this will help to properly assemble the phone back.
- π© Unscrew 10 screws (they are of different sizes!) with a screwdriver T3. Put them in a container in groups.
- π±οΈ Unplug the battery plume with a plastic blade. Never pull the wires!
- π Check the integrity of the sealing rubber around the camera β if it is torn, dust will hit the lens.
In the Redmi Note 8 Pro, the fingerprint scanner plume is attached to the lid, so when it is removed, it automatically detachs from the motherboard. Don't be afraid, that's okay. The main thing is, don't bend the plume and pull it.
| Element | Number of screws | Type of screwdriver. | Notes |
|---|---|---|---|
| Back cover. | β | β | It's on glue + latches. |
| metal plate | 10 | T3 | Rotors of different lengths! |
| Battery plume | β | β | Detached by a spatula |
| Camera. | 2 | T3 | Rubber-stamped screws |
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 mistakes and ways to prevent them:
- π₯ Overheating of the body - if you hold the hair dryer too close, plastic clips inside can deform.Optimum temperature: 70Β°C (holding the hand, but not holding it for long).
- π₯ A sharp lid pulling - the glue can pull the fingerprint sensor plume behind it. Always check if anything is clinging to the body.
- π Forgetting to disconnect the battery -- if you accidentally close your contacts, your phone can burn!
- π± Confuse screws when Assembly - in the Redmi Note 8 Pro there are screws length of 3 mm and 5 mm. If you screw a long screw into a short hole, you can damage the motherboard.
Another common problem is that the seal rubber around the chamber is damaged, and if it breaks, moisture and dust will get in, causing the lens to fog or corrosion of the contacts, and when you assemble it, make sure that the rubber is flat and not twisted.
1. Is the battery plume connected?
2. whether the metal plate is correctly installed (it closes the power contacts).
3. Whether the fingerprint scanner plume is bent (it can block the activation).-->
How to glue the lid back: tips and materials
If you remove the lid for repair, you need to fix it properly when you build it, and services use a special 3M double-sided tape or B-7000 glue, but there are alternatives:
- π¦ Original adhesive layer β if you carefully removed the old tape, it can be reused (warm up with a hair dryer before sticking it on).
- π§΄ Moment "Crystal" glue - is applied in a thin layer around the perimeter, but requires drying 2-3 hours.
- π Bilateral Scotch width of 5-8 mm - glued only on the edges, without overlapping on the connectors.
Sticking order:
- Clean the edges of the case and cover of old glue (use isopropyl alcohol).
- Apply new glue or tape, leaving the areas near the connectors and buttons free.
- Line the lid and press it, starting at the top (where the camera is).
- Warm up the edges with a hair dryer (50β60Β°C) for better grip.
- Put your phone under a press (such as a stack of books) for 10-15 minutes.
β οΈ Warning: If the lid wobbles or moves away in corners after assembly, then there's not enough glue. Don't use superglue or PVA, they can damage the plastic and make subsequent disassembly impossible.
When is the best time to contact the service
Not all breakdowns can be repaired on your own, but here are some cases where disassembling the Redmi Note 8 Pro at home is unnecessarily risky:
- π Cracked glass cover β when removed, it can crumble, injuring your hands or damaging internal components.
- π Charging problems β if the phone isnβt charging, the cause may be a burnt-out controller, not a battery.
- πΆ Lack of network β often associated with damage to antenna contacts, which are easy to tear off during careless disassembly.
- π Cyclical reboot β indicates motherboard problems requiring equipment diagnostics.
The average cost of dismantling in the service is 800-1500 rubles (depending on the region). If you are not confident in your abilities, it is better to pay professionals than risk damage to the display plume (it will cost 3000-5000 rubles). Xiaomi service centers use ultrasonic baths to safely remove glue and special devices for uniform pressing of the lid.
π‘
The main rule: if the lid does not respond after 3-4 attempts, do not put more effort. In 90% of cases, this leads to expensive repairs. It is better to consult specialists or buy a non-original back panel (cost - from 1200 rubles).
