Disassembly Xiaomi Redmi 6 Pro: instructions with photos and warnings

Xiaomi Redmi 6 Pro is a popular budget smartphone of 2018, which is still in active use. However, over time, even the most reliable equipment requires repairs, whether it is a battery replacement, a display or dust cleaning. If you decide to disassemble the device yourself, it is important to do it carefully so as not to damage fragile components.

In this article, you will find step-by-step instructions with photos, a list of necessary tools and critical warnings to help avoid typical errors. We will also tell you which parts most often fail, and give you tips for replacing them. If you have never disassembled a smartphone, don’t worry: Redmi 6 Pro is a device with a medium level of disassembly complexity, and even a beginner can cope with the right approach.

Before you start, consider: self-disassembly will void the warranty (if it is still valid) and can lead to irreversible damage if you carelessly handle.

Preparation for disassembly: tools and security measures

Before you disassemble the Xiaomi Redmi 6 Pro, prepare the workplace and the necessary tools, which will save time and reduce the risk of damage to parts.

• 🔧 Plastic mediators or shoulder blades (2-3 pcs. - for careful smacking of the housing and disconnection of the plumes.
• ⚙️ A PH00 cross screwdriver is used to twist screws (usually 10-12 pieces).
• 🔥 A dryer or thermo-air station is used to soften the glue under the screen (if you plan to remove it).
• 🧲 Magnetic mat or organizer – so as not to lose small screws and details.
• 📱 Screen suction cup - will help to tamper with the display module.
• 🔌 Tweezers for working with small connectors and plumes.
• 🛡️ Antistatic bracelet (optional) – protects the board from static electricity.

Also, make a clean, well-lit workplace without carpets or fabric coatings -- they store static electricity. Better a hard-surface desk. If you're taking your smartphone apart for the first time, take a picture of each step, which will help you get the device back together properly.

⚠️ Warning: Don't use metal tools to tuck in plastic latches! This will cause chips and cracks on the body. Plastic mediators can be replaced with guitar mediators or bank cards (but they are less convenient).

Removal of the back cover: design features of the Redmi 6 Pro

Unlike many modern smartphones, the Redmi 6 Pro has a removable back cover, but it is not only attached to the latches, but also to the glue, which complicates the process, since if you take it off sloppy, you can damage plastic clips or tear antenna contacts.

Algorithm of action:

1. Turn off your smartphone and remove the tray for SIM-cards (use a paper clip or special key).
2. Heat the back cover with a hair dryer (~60°C) for 1-2 minutes to soften the glue. Don't overheat - the plastic can deform!
3. Insert a plastic mediator into the gap between the lid and the case (start at the bottom edge where the charging connector is located).
4. Carefully swipe the mediator around the perimeter, gradually disconnecting the latches. If the lid does not respond, warm up the problem area again.

After removing the cover, you will see:

• 🔋 Battery (stick to the body).
• 📶 Antenna contacts (thin metal strips - don't tear them off!)
• 🔊 Speaker and microphone (mounted on plastic frame).

⚠️ Warning: If you notice that the antenna contacts have come off after you remove the lid, don't try to glue them with superglue! Use a special conductive glue (e.g. Permatex) or contact the service.

Battery Disconnection: Why It’s Critical to Do It in the First Place

Before touching any components inside your smartphone, be sure to turn off the battery.This will prevent short circuits that could disable the motherboard or other modules. In the Redmi 6 Pro, the battery is glued to the body, so removing it requires caution.

Procedure:

1. Unplug the protective film (if any) from the battery connector - it is located at the top of the board.
2. Carefully put a plastic blade on the plume and unplug it from the connector.
3. If the battery is swelling, don't try to prick or bend it. This can cause fire, in which case it's better to replace the battery immediately (original article: MB03008, capacity 4000 mAh).

For full battery removal:

• Tap the battery with a plastic blade on the side (where there are no board components).
• If the glue is too strong, drop a few drops of isopropyl alcohol (90%+) under the battery - it will dissolve the glue without harming electronics.
• After extraction, clean the body of glue residues with alcohol or acetone.

💡

If the battery doesn't turn on after you change the battery, check if the battery plume is properly connected. Sometimes it may seem connected, but it doesn't really sit all the way.

Motherboard removal: connectors and traps

The Redmi 6 Pro motherboard is mounted on 10 screws (of different lengths!) and several plumes, and the main difficulty is not to confuse the screws when reassembled, as too long a screw can damage the board.

How to charge:

1. Unscrew all screws (note: 2 screws near the chamber shorter than the others).
2. Carefully disconnect the plumes in the following order: 📷 Main camera 🔊 Speaker/microphone 📶 Antenna cables (3 pieces) 🔋 Charging connector /USB-Type C

Tap the board with a plastic spatula on the side (where there are no components) and gently lift.

Common mistakes when working with the fee:

• ❌ Use of metal tools → risk of closure.
• ❌ Use of force when disconnecting plumes → contact break.
• ❌ Tangled screws → board damage during assembly.

On the back of the board are located:

• 📱 Memory chip (if you plan to upgrade, please note that Redmi 6 Pro does not support memory replacement).
• 📡 Module Wi-Fi/Bluetooth (often fails when overheated).
• 🔌 Power controller (if the smartphone isn't charging, check this chip).

Screen Replacement: When It Is Needed and How to Do It Right

The Redmi 6 Pro display is one of the most vulnerable places, most often it is changed after falls, when cracks, broken pixels or a broken touchscreen appear. The cost of the original module (article: MB03010) is about 2500-3500 rubles, but you can find quality analogues cheaper.

Signs that the screen needs to be replaced:

• 🖥️ Vertical/horizontal bands on the display.
• 👆 Touchscreen does not respond to touch or works partially.
• 💥 Cracks, broken glass (even if the image is normal).
• 🔍 The lights are flashing or not turning on.

Replacement process:

1. Remove the back cover and turn off the battery (as described above).
2. Heat the screen with a hair dryer (temperature ~70°C) for 3-5 minutes to soften the glue.
3. Suction the display module on the bottom edge and carefully separate it with the mediator. Be careful - there are plumes under the screen!
4. Disconnect the plumes of the display and touch screen (they are located under metal protection - it must be unscrewed beforehand).
5. Install a new screen, plug in the plumes and check the operability before final assembly.

⚠️ Warning: If color distortions (such as pink) appear after the screen is replaced, you may have damaged the display plume, in which case you will need to replace the plume or module itself.

💡

When buying a new screen, pay attention to the version: for the Redmi 6 Pro, only modules with a resolution of 1080×2280 and a cutout for the camera ("monobrov") are suitable.

Common breakdowns and their diagnosis

If you've taken down the Redmi 6 Pro for repair, it's helpful to know which faults are most common and how to identify them.

You can use a multimeter in vertebrae mode to diagnose the circuit, for example, to check the power circuit:

1. Connect the black probe to the battery minus.
2. With a red probe, touch the contacts of the charging connector (the first and fourth contacts are plus and minus).
3. If the resistance tends to infinity, the chain is broken (the contact may be cut off).

If you're not sure about your soldering skills, it's best to entrust the board repair to professionals. Modern smartphones have multi-layered boards, and sloppy soldering can damage adjacent lanes.

Smartphone Assembly: How to Avoid Mistakes

Putting the Redmi 6 Pro back together is often harder than disassembling, and the rule is, go backwards and make sure all the plumes and connectors are tightly connected.

• 🔩 Screw the screws cross-curl to avoid skewing the board.
• 🔌 Before final assembly, check the operability of all modules (camera, speaker, touchscreen).
• 📶 The antenna contacts must fit tightly to the housing, otherwise the network signal will deteriorate.
• 🔋 Stick the battery onto double-sided tape (e.g., 3M 9448A) — it is more reliable than the original adhesive.

Typical errors in assembly:

• ❌ Forgot to plug the touchscreen plume → the screen is working, but doesn't respond to touch.
• ❌ Mixed screws → board deforms when twisted.
• ❌ Not tight enough closed back cover → there are gaps.

After assembly, turn on the smartphone and check:

1. Charging (plug the cable and make sure the current is running).
2. Sensor (take the test in Settings → About Phone → Diagnostics).
3. Camera (take a test shot).
4. Sound (call the speaker and microphone).

⚠️ Warning: If the smartphone gets too hot after assembly, turn it off immediately! most likely, there has been a circuit somewhere (for example, due to an improperly laid plume).
