How to unplug the plume in the Xiaomi Redmi phone: a step-by-step guide

Disassembling a modern smartphone is a process that requires not only accuracy, but also a clear understanding of the internal architecture of the device. If you are faced with the need to replace a broken display, turn off a swollen battery or simply conduct a deep cleaning of dust, you will inevitably have to face the task of detaching the plume in the Xiaomi Redmi phone. Wrong actions at this stage can damage the connectors on the motherboard, which will turn a simple repair into an expensive procedure for restoring electronics.

In modern models such as the Redmi Note or Xiaomi Mi series, manufacturers use different types of mounts and plume arrangement. Some connectors are fixed with metal clipplates, others are simply inserted into the connector with force, and others have special latch locks. Understanding the type of connection is critical before any manipulation, since the force applied to one type can be destructive to another.

Before you start dismantling, you need to prepare the workplace, you need good lighting and an antistatic mat or just a clean, dry surface, so working without grounding and special tools increases the risks, especially if the room is dry.

Required tools and workplace preparation

Quality repairs begin with the right tool. You don't need industrial equipment to work with Xiaomi components, but the kit must be specialized. Use of improvised tools such as kitchen knives or pins is strongly discouraged, as they can damage fragile body elements or close contacts.

The main set of the master should include the following subjects:

• 🔧 Torx screwdriver set (usually) T5 and T6) and cross-bars for the hull screws.
• 🛠 Plastic blades (spoogers) and mediators for opening the body without scratches.
• 🌡 Thermal dryer or heating pad for softening the glue under the back cover.
• 🧲 Magnetic mat or organizer for sorting screws of different sizes.

Special attention should be paid to mediators. Metal tools can only be used to work with metal shields, but they are forbidden to touch directly plumes or connectors. Plastic does not conduct current and does not leave microscopic particles on contact groups, which preserves the tightness of the connection after reassembly.

⚠️ Warning: Before starting any work, be sure to turn off the device completely. If the phone does not respond to buttons but makes sounds or vibrates, try to discharge the battery to zero or gently turn off the battery first thing if the design allows you to do this without full indiscriminateness.

Types of connectors and plumes in Xiaomi smartphones

There are several types of connections inside Redmi smartphones, and knowing how they work helps avoid touch-like breakdowns, most often through wide flat plumes that are inserted into the board's connectors.

There are three main types of mounts you will encounter:

• 🔌 Press-fit: The plume is simply inserted into the connector before clicking and fixed by friction. To turn it off, you need to gently tuck it with a plastic blade from the end.
• 🔒 Latch (Latch): above the connector is a movable bar, which must be bent up before removing the plume.
• 📎 Pressure plate: the plume is covered with a metal bracket on the screws, which must be twisted out before accessing the contacts.

The most vulnerable are the latch connectors. If you try to pull the plume without throwing the latch, you are guaranteed to damage the connector on the board. In Redmi Note 9/10/11 models, a combined type of mount is often found, where some of the plumes are covered with a common metal protection, screwed to the frame.

Sequence of disassembly of the Redmi body

The process of accessing the internal components depends on the design of the particular model. Most modern Xiaomi have a glass or plastic back cover glued around the perimeter. Start by heating the edges of the body with a hairdryer to a temperature of about 80-90 degrees Celsius, which will soften the glue and allow the case to open without chipping.

Then you should act on the algorithm:

1. Remove the tray. SIM-map.
2. Warm up the perimeter of the back cover evenly, without holding the hair dryer for a long time at one point.
3. Insert the suction cup into the bottom of the lid and create a tension.
4. In the resulting gap insert a plastic mediator and lead them along the edges, cutting the adhesive layer.

Once the lid is removed, you will have access to the inside, and in some models, such as the Redmi K or Poco series, there may be an additional decorative plate with a logo under the back cover, which also needs to be carefully removed, only after that you will see the motherboard and the main plumes.

Technology of safe shutdown of plumes

The most critical thing is to physically shut down the connectors, and it's not the force that matters, it's the right technique, so if you see a plume covered with a metal plate, first twist the screws that hold it, and the screws can be of different lengths, so remember or plot them.

To turn off, use a plastic blade or a special antistatic tweezer. The plume should not be smeared for the flexible part itself (it is easy to tear), but for a rigid plastic tip or a special tongue, if it is provided by the design. The movement should be directed upward, parallel to the plane of the board, without distortion.

The table below shows the features of working with different nodes of the smartphone:

If the plume is not amenable, don't use excessive force. Examine the connection again: you may not have noticed the locking element or screw that holds the pinning bar. In Xiaomi models with moisture protection, the connectors can be further sealed, which requires more careful tweaking.

⚠️ Warning: Never pull the plume over its thin, flexible part, which causes the internal conductors to dissect, and visually the whole connection stops transmitting the signal.

Specifics of working with the battery and display

Turning off the battery is often the first step in serious repairs to turn off the board.In Redmi smartphones, the battery is usually glued to a frame or back cover on double-sided tape.Be sure to unplug the battery plume from the motherboard before attempting to retrieve.

To safely turn off the battery plume, use a plastic card or spatula. Tuck the connector from the bottom up. If the battery is connected through a wire connector (in older models), act even more carefully to avoid pulling the wires from the soldering. After disconnecting between the battery contact and the board connector, it is recommended to lay a dielectric (a piece of plastic) to avoid accidental switching on.

When working with the display, the situation is more complicated. The matrix plume and touchscreen are often under a metal screen that is screwed to the middle frame. You will have to twist all the screws around the perimeter of the board. Note that in some Xiaomi models, the fingerprint scanner can be integrated into the display plume, and it is required to turn off before the screen is completely removed.

💡

Use isopropyl alcohol to clean the contacts. If the plume was off long ago, the contacts could form an oxide layer that degrades the signal. Wipe the contacts with a soft lilaless napkin soaked in alcohol.

Frequent errors and precautions

Beginners often make mistakes that lead to additional costs, and one of the most common is trying to turn off the plume under voltage. Even if the phone is software-enabled, there may be a residual charge on the board, and shorting the pintweezers can burn the power controller.

Another mistake is to use metal tools where plastic is needed, and metal can slip and break through the insulation of adjacent components, or leave a micro-crack on the ceramics of capacitors, and it is also dangerous to heat the battery area with a hairdryer if it is already connected, which can cause it to swell or ignite.

To minimize the risks, follow these rules:

• 🔋 Always turn off the battery first as soon as you access it.
• 🙅‍♂️ Do not use force where there should be movement with light effort.
• 👀 Visually check the integrity of the plume before installing a new module.

Assembly and performance check

After you have done the necessary manipulations (replace the screen, clean or turn off), you start the assembly phase, you put the plumes in reverse order, you need to insert the connector smoothly, without distortion, and you need to press on a quiet but clear click, indicating that you are fixing.

So, don't rush to swirl all the screws and glue the lid right away. First, plug the battery and the display, then press the switch. If the screen catches fire, the touchscreen and the sound work, you've done a good job. Only after a successful test can you fix the board with screws and return the case to its original state.

If the phone doesn't turn on or the sensor isn't working properly, don't panic. It's likely that the plume is not fully inserted or squeezed. Re-disassemble the device and check the density of the connection. Sometimes it helps to gently wipe the contacts with a blower to remove the static charge.

⚠️ Warning: If the phone starts to discharge quickly or warm up in the camera/processor area after assembly, turn it off immediately.This is a sign of a misplaced plume or short circuit that could damage the motherboard.

💡

The secret to success is patience. Take your time to pull the screws and pull the plumes. Every movement must be conscious and the tool must be appropriate, and this will save you money on buying new parts.
