Why to Disassemble Xiaomi Pro and What to Know Before Starting
Disassembling the Xiaomi Pro is a challenge that owners face when replacing a battery, repairing a screen or cleaning from dust. However, it is not as simple a procedure as it may seem. Modern Pro models (whether Redmi K50 Pro, POCO F5 Pro or Mi 12 Pro) have a complex design with adhesive joints, brittle plumes and moisture protection. One wrong move - and you risk damaging the motherboard or display.
In this article, we will take a step-by-step disassembly process based on the features of different models, list the necessary tools and tell you how to avoid typical errors, and you will learn when to contact the service center, and when you can manage yourself. Importantly, disassembling a smartphone deprives it of warranty — if your Xiaomi Pro is still in warranty service, first specify the conditions in the official service.
Before you start, answer three questions:
- Do you have experience with small electronics?
- Are you ready to be left behind after the slack?
- Do you have spare parts (such as a new battery or adhesive to build)?
If at least one question the answer is “no”, it is better to entrust the repair to professionals.
Preparation: tools and materials for disassembly
Without the right tools, it’s almost impossible to disassemble the Xiaomi Pro. Here’s the minimum set you’ll need:
- 🔧 Plastic blades (2-3 - for tidy fitting of the body. Metal tools can scratch the frame.
- 🔨 Pentalobe screwdriver P2 — for screws in the bottom of the smartphone (models) POCO Pro and Redmi Pro are often used such screws).
- 🔧 Phillips screwdriver #00 - for internal fastenings.
- 🧲 Magnetic mat or tray – so as not to lose small screws and details.
- 🔥 Dryer or thermal air station - for softening the glue (especially relevant when replacing the battery).
- 🧴 Isopropyl alcohol (90%+) — Cleaning contacts and removing glue residues.
- 📦 New glue tape (e.g., scotch, 3M 9448A) — post-assembly sealing.
Some models (such as the Xiaomi 12 Pro or Black Shark 5 Pro) may require special suction cups to remove the screen, and we recommend using an antistatic bracelet to avoid damage to the chips by static electricity.
⚠️ Warning: Do not use knives or other sharp objects to tweak the body! this is almost guaranteed to damage the plumes or body.

Step-by-step: how to disassemble Xiaomi Pro without damage
The disassembly process can be divided into three stages: removing the back cover, disconnecting the battery and accessing the internal components.
Step 1: Removal of the back cover
1. Turn off your smartphone and make sure it is completely discharged (this will reduce the risk of short circuit).
2. Heat the back cover with a hair dryer (temperature ~60°C) for 2-3 minutes to soften the glue. Keep the hair dryer 10-15 cm away so as not to overheat the plastic.
3. Insert a plastic blade into the gap between the body and the screen (usually starting at the bottom edge where the speakers are located). Carefully swipe the shoulder blade around the perimeter, separating the lid. If you feel resistance, warm up the place again.
The POCO F4 Pro and Redmi K60 Pro often have the back cover attached to the latches. If you hear a characteristic click, don't be alarmed, that's okay. The main thing is, don't put too much effort into it.
Step 2: Battery disconnection
When you take the lid off, you'll see the battery covered by a metal plate.
- Unscrew the screws that hold the plate (usually 4-6 pieces).
- Carefully slap the plate and put it aside.
- Unplug the battery plume with a plastic blade. Don't pull the wires! Better grab the connector on the side.
- If the battery is "glued" - again use a hair dryer to soften the glue, then tuck it with a spatula.
⚠️ Warning: Don't puncture the battery or bend it! lithium batteries can ignite if damaged.
Stage 3: Access to the motherboard and other components
Now we can start to disassemble the insides:
- Unscrew all the screws that hold the motherboard (there can be 10-15 pieces, depending on the model).
- Carefully disconnect all the plumes: display, cameras, buttons, etc. Remember or photograph their location!
- Remove the metal screen (if any) and remove the motherboard.
At this stage, you get access to all the key components: memory chip, camera module, Wi-Fi antennas, etc. However, remember: each plume is fragile, and its cliff can bring the smartphone down.
What to do if the screw is broken or jammed?
Features of disassembling popular models Xiaomi Pro
The design of the Pro series smartphones can vary significantly depending on the model, and the following are key nuances for the most common devices.
| Model | Features of disassembly | Typical problems |
|---|---|---|
| Redmi K50 Pro | The battery is very glued, it requires a lot of heat, and the display module is connected to the frame with latches. | The latches of the screen often break when you take them carelessly, and the fingerprint scanner's plume is very fragile. |
| POCO F4 Pro | The back cover is glass, and there's a high probability of cracking when you disassemble it, screws under the cover of different sizes. | If you overheat the hair dryer, the glass can crack. The plume of the vibrating motor breaks easily. |
| Xiaomi 12 Pro | An IP53 case is a lot of glue and sealant, and the battery is split in two. | It's hard to separate the screen without damage, and when you assemble it, you have to seal all the joints carefully. |
| Black Shark 5 Pro | Additional screws under physical buttons (Game Triggers) liquid cooling system. | If the cooling tube is damaged, the smartphone will overheat. The buttons are easy to lose when disassembling. |
If you’re disassembling the Xiaomi Pro with water protection (like the Mi 11 Pro or 12S Pro), make sure to check the leakproofness after assembly with a waterproof test (for example, submerging the smartphone in water for a short time only after full assembly and gluing).
💡
Before assembly, clean all contacts with isopropyl alcohol - this will improve the connection and prevent corrosion.
Common Mistakes in Disassembly and How to Avoid Them
Even experienced craftsmen sometimes make mistakes that lead to a smartphone breakdown, and here are the most common ones:
- 🔥 Battery overheating - if you heat it with a hair dryer for too long, the battery can swell or even ignite.Optimum temperature — 60-70°C, no more.
- 🔧 Loss of screws — screws in Xiaomi Pro are often of different sizes. If you confuse them with places, you can damage the board.
- 📱 Train breaks -- display and camera plumes are particularly affected. Always pull the connectors on the side instead of pulling the wires.
- 💧 Moisture intake -- if you take your smartphone apart in a wet room, the contacts can oxidize.
- 🔌 Short circuit – if you touch the board with metal tools when the battery is on, it can put it out of action.
Another common problem is that the flexible power button cable is damaged, and it's located next to the board, and it's often glued, and when it breaks, the button will stop working, and it can be difficult to replace this tail separately.
⚠️ Warning: If the smartphone doesn't turn on after disassembly, don't panic. First check: Is the battery connected, is the display plume damaged, is all the screws in place (sometimes an untwisted screw closes the contacts).
💡
If you are not sure of your abilities, it is better to contact the service. Repair after an unsuccessful self-disassembly often costs more than the original problem.
Assembly of the smartphone after disassembly: nuances and verification
Building Xiaomi Pro is no less important than disassembling. Here are the key points:
- Check all the plumes - they should be tightly connected, without distortion.
- Apply new glue - if you were removing the battery or back cover, the old glue has lost its properties.Use 3M 9448A or a similar double-sided scotch.
- Twisting all screws – a missed screw can lead to poor contact or damage to the board.
- Do a test -- before you finish building, turn on your smartphone (without closing the lid) and check: Is the screen working, are the buttons responding, are the battery charging, are the cameras and speakers functioning.
If the smartphone overheats after assembly, you may have forgotten to connect the cooling system (relevant to Black Shark Pro) or installed the thermopaste incorrectly (in liquid-cooled models).
To check the tightness (if the model has water protection), you can use a moisture resistance test:
- Place your smartphone in a plastic bag with silica gel for 12 hours.
- If condensation appears inside the package, the tightness is broken.
When disassembly is inappropriate: cases for a service center
Not all breakdowns can be repaired on their own, but here are the situations where it is best to consult a specialist:
- 🔧 Damage to the motherboard – if the smartphone is not turned on, is not detected by the computer and does not respond to charging, the cause may be a short circuit or burnt out chips.
- 📱 Fractured screen with matrix damage – Replacing the display module in Xiaomi Pro often requires gluing the glass layer, which is difficult to do without experience.
- 💧 Liquid intrusion - even if the smartphone turned on after drying, corrosion could damage the contacts.
- 🔋 A bloated battery is dangerous, a battery like this can't be pierced or heated, but it's better to take it to a service for recycling and replacement.
It’s also worth considering that some models (such as the Xiaomi 13 Pro) have hidden screws under the stickers. If you don’t notice them, the body will not fully understand, and if you try to force you risk breaking the latches.
The cost of repair in the service may seem high, but it is often justified. For example, replacing the screen with the Redmi K60 Pro in the official service will cost 15-20 thousand rubles, while a self-replacement with the risk of damage to the matrix can result in 30 + thousand rubles.
💡
If your Xiaomi Pro is guaranteed, the disassembly will cancel it, in which case always contact an authorized service center.
