How to disassemble the Xiaomi Redmi 6 phone: a detailed guide

Disassembling a modern smartphone is always a balance between accuracy and determination. Xiaomi Redmi 6, released in 2018, became popular due to the ratio of price and performance, but over time requires intervention in the “iron”.

The process of dismantling this device is not elementary, because the Chinese manufacturer used hidden screws and adhesive pads. Quality preparation of the workplace and the availability of a specialized tool is the key to success. Wrong actions can damage the plumes or even fire the battery, so it is important to understand the sequence of actions.

In this guide, we will take a detailed look at each step, from turning off the power to removing the display module, where the screws hide under the stickers and how to safely unplug fragile connectors. Even if you are a beginner, following the instructions will allow you to carry out repairs with minimal risks.

⚠️ Warning: Before starting any work, make sure that the battery level is below 25%.Working with a fully charged battery significantly increases the risk of fire or bloating if accidental damage to the housing.

Tools and workplace preparation required

The Redmi 6 is not a successful disassembly without the right toolkit. Unlike older push-button phones, modern monoblocks require precision, and you'll need not just a screwdriver, but a whole arsenal for delicate work.

First of all, prepare a suction cup or a thin plastic spatula (mediator). Metal tools are strongly discouraged, as they can easily damage the glass or short contacts on the board. Also an indispensable assistant will be a hair dryer for heating the adhesive layer.

Organize the space so that small details are not lost. The screws in Xiaomi smartphones can vary in length even within the same lid, and their entanglement threatens to break the motherboard.

• 🔧 A set of screwdrivers with Torx nozzles T5 cross-and-cross PH000
• 📱 Plastic blade or mediator for opening the body
• 🌡️ Hair dryer or heating platform for softening glue
• 🧲 Magnetic mat or organizer for screws
• 🧤 Antistatic gloves (optional, but desirable)

Make sure you have good lighting. Small plumes and connectors are not visible in dim light, which increases the risk of error. Safety should be a priority, so remove flammable objects from the access area.

Primary steps: SIM removal and rear cover dismantling

We begin the direct analysis of Xiaomi Redmi 6. The first step is the extraction of the tray for the SIM-Use a paper clip or a special needle with a pressure in the hole on the bottom end. Do not try to pull the tray out with your nails so as not to damage the mechanism.

Then comes the most difficult step, which is to separate the back cover, and it's attached to a double-sided tape around the perimeter, turn on the hair dryer and warm the edges of the body evenly for 2-3 minutes, and don't hold the hair dryer too close to melt the plastic.

After heating, insert a plastic card or a shoulder blade into the junction between the frame and the lid. Carefully guide the tool along the perimeter, gradually snapping the adhesive layer. Sharp movements can lead to cracks in the glass.

💡

If the lid fails, do not use force. Reheat the problem area with a hair dryer for 30-40 seconds. The glue should become elastic.

When the lid is removed, you'll see the internal layout. Notice the state of the battery: it should not be bloated. At this point, you can see the main nodes that need to be handled carefully.

Disassembly of the internal structure and removal of protection

Under the back cover is a metal frame or plastic panel covering the motherboard. Redmi 6 is often a plastic pad, which is also secured by screws, and their number can vary, but usually there are about 10-12 pieces.

Carefully inspect the perimeter and the centerpiece, some screws may be hidden under serial number or warranty seals, and their removal may result in a loss of warranty, but repairs often require this.

After you twist all the screws you see, gently lift the shield, underneath it is the motherboard, the main camera module and the top plume, and proceed slowly, because short plumes can be attached to the panel.

• 🔍 Look for screws under stickers at the bottom and top
• 📷 Be careful with the main camera plume.
• 🔋 Check the integrity of the battery connector before removing the protection
• 🧩 Disconnect the speaker antenna wire if it interferes with access

It is important not to damage the antenna cable, which often passes under protective elements, and its damage will lead to deterioration of the quality of communication and Wi-Fi.

Disabling the plumes and retrieving the battery

This is a critical point of the procedure. Before you take out the battery, you need to turn off the device, find the battery connector on the motherboard, and gently disconnect it with a plastic blade.

Only after the power is turned off can you start to use other components, disconnect the plumes of the display, touch screen and cameras, and they are fixed by special latches that you need to bend upwards, not pull to the side.

The battery in Redmi 6 is glued to a frame. Use a suction cup or special sticky tape to extract it. Strip the tapes under the battery and pull them over yourself, gradually separating the battery.

⚠️ Warning: Metal tools are strictly forbidden to use to smack the battery.Puncture of a lithium-ion battery causes instant ignition and release of toxic gases.

If the battery is swelling, be especially careful, the pressure inside the housing can be high, in which case the replacement should be carried out in a well-ventilated room.

Removal of the display module and touch screen

The display module is the most fragile and expensive element. In Redmi 6, it can be assembled with a frame or separately. If you change only the glass, the process requires a separator and skill, but it is easier to completely replace the action module.

After turning off all the plumes going to the screen, the module is held only by glue around the perimeter. Again use heating, but more carefully so that you do not damage the matrix if you plan to use it again (although this rarely works).

You can push the module around the perimeter, evenly distribute the force. If one side moves more easily, don't just pull on it, warm up the opposite edge. A sharp jerk can tear the plume of the touchscreen.

The new module should be checked before installation, connect the plumes to the board without gluing the screen, and turn on the phone, check the sensor and the presence of broken pixels.

Comparison of the features of the Redmi 6 components

When replacing parts, it's important to understand what components you're working with, and different smartphone revisions might have different parts, even though the basic architecture is the same.

As you can see from the table, the battery is the most voluminous element. The BN42 is the standard for this series. Always check the labeling when buying parts.

The cameras, despite having two modules, are shot in a similar way, and the key is not to lose the rubber seals around the lenses, they protect against dust.

Device assembly and final inspection

You build it in reverse order, but with a lot of care, so you can install a new battery and connect it to the board right away, and make sure that the phone responds to the push of the power button.

Put all the plumes in your channels so that they are not squeezed by a frame. Incorrectly stacked plume is a common cause of a broken touchscreen or microphone after assembly.

Stick the back cover using fresh glue or double-sided tape. Press the edges around the perimeter evenly and let the device lie under the load (not too heavy) for about 30 minutes.

• 🔌 Connect the charger and check the indication
• 📞 Make a test call to check the speakers
• 📸 Open the camera and check the focus.
• 📶 Make sure Wi-Fi and Bluetooth work

If all systems are working properly, you can consider the repair complete. Don't rush to twist all the screws at once - it is better to check the device in the open first.

⚠️ Warning: If the phone doesn't turn on after assembly, don't panic. Remove the lid again and reconnect the battery connector. Often the problem is that the plume is not fully inserted.
