How to disassemble Xiaomi Redmi Note 5A: step-by-step instructions

Disassembly of the Xiaomi Redmi Note 5A smartphone is often a necessity when the device stops working correctly or requires replacing failed components. The most common reason for referring to the “inners” of the gadget is a broken display module or bloating of the battery, which critically affects the safety of operation. Unlike flagship models with non-removable rear covers, the budget segment, which includes the Redmi Note 5A, has its design features that require careful approach.

The process of dismantling this device is not overly complex, but requires some skill and the presence of a specialized tool. Careless handling of internal plumes or disruption of the sequence of actions can damage the motherboard, which will make further repairs economically inexpedient. In this article, we will look at each step in detail, from the preparation of the workplace to the final assembly, so that you can perform the procedure efficiently and without unnecessary risks.

Before you start taking action, it is important to understand that the Xiaomi Redmi Note 5A (Riva model) is structurally different from its brother Redmi Note 5A Prime (Ugg model).The main difference lies in the materials of the case and the location of some elements, so before you start work, make sure that your instructions match your modification of the phone.

Tools and workplace preparation

The quality disassembly of any electronic device begins long before you pick up the screwdriver. You need to organize a spacious, well-lit workplace where the small details are not lost, and the risk of accidental fall of the smartphone will be minimized. The surface of the table should be flat and, preferably, covered with a soft antistatic mat or at least a clean sheet of white paper on which the screws are clearly visible.

To work with the Redmi Note 5A, you will need a standard mobile wizard toolkit, which can be purchased from any radio or electronics store. The lack of specialized equipment often leads to failure of the screw threads or damage to the plastic latches of the case, which greatly complicates the assembly process.

• 🔧 A set of precision screwdrivers (mandatory presence of cross-shaped) P2/P5 flat-slit).
• 🎴 Plastic spatula (mediator) or thin metal scalpel with caution.
• 🔥 Dryer or heat pad to soften the glue under the screen (if it is planned to replace it).
• 🧲 Magnetic mat or organizer for sorting screws of different sizes.
• 🧤 Antistatic gloves and tweezers for working with small plumes.

⚠️ Before starting any work, be sure to turn off the smartphone and remove SIM-card and memory card: Attempting to disassemble the switched-on device may short-circuit and cause irreversible damage to the power controllers.

Pay special attention to the condition of the tools. The sting of the screwdrivers should be magnetic, but not too strong so as not to damage the chips, and plastic blades should not have serrated dents that can scratch the frame of the case. Using a quality tool is a guarantee that you do not damage the external elements during dismantling.

Rear cover removal and initial inspection

Unlike many modern smartphones, the Redmi Note 5A has a removable back cover, which makes it much easier to access the internal components at the initial stage. However, this does not mean that the lid can be pulled off with force; it is held on plastic latches around the perimeter of the body, which easily break when sloppy handling. First, you need to turn the device down and carefully examine the ends for visible screws - in this model they are not, all the mount is built on clips.

Start the opening from the bottom corner, closer to the charging jack, gently inserting a thin plastic blade or mediator into the gap between the frame and the lid. Slowly guide the tool along the side face, hearing the characteristic clicks of the undocking latches. Do not use metal objects such as knives or wide screwdrivers, as they can leave deep scratches on the glossy plastic or, worse, damage the tail of the side button passing in the immediate vicinity.

Once all the latches around the perimeter are free, remove the back cover, access the battery, the main camera module, and the bottom of the motherboard, and at this point, it's important to visually assess the condition of the internal components, whether there are any signs of corrosion, battery bloating or unstuck plumes. Often, visual inspection helps diagnose the problem without deep disassembly.

💡

In order not to confuse the screws during assembly, spread them in the same order in which you twisted them, or use a magnetic mat with markings.

Removal of plastic protective panel

Under the rear removable cover, there's a large plastic panel that covers most of the interior space of the smartphone, protects the motherboard and other sensitive elements from dust and mechanical stress, and it's secured with a lot of screws of different sizes, so it's important to be as careful as possible and not to put too much effort into it if something isn't unscrewed.

The first thing you need to do is to unscrew all the visible screws that attach this pad. In the Redmi Note 5A, they can be as many as a dozen screws, and they're not just around the perimeter, but in the center, sometimes hidden under stickers or markings. Use a screwdriver with the right size of the sting so you don't rip the screw caps off, which will turn a simple repair into a difficult task to drill the fastener.

After removing all the screws, take a quick look at the panel, and underneath it, you can see plumes that go to the volume and turn on buttons that are located on the side of the panel. Carefully raise the edge of the panel and check if any connectors need to be disconnected. In this model, the button plumes are usually long enough, but it is better to be safe and act slowly so as not to break the thin conductors.

Battery shutdown and board dismantling

Once the safety panel is removed, you can access the main nodes of the smartphone. The first and most important step is to turn off the device. Find the battery connector on the motherboard and gently disconnect it. This is a critical step to prevent short circuits when working with other components, such as the screen or vibrator.

To turn off the plume, use a plastic blade or nail, pulling the connector from the bottom up. Under no circumstances pull the battery wires themselves, as they can break away from the contact area. After the power is turned off, you can start dismantling the motherboard itself, which is secured by several screws and sits tightly in its seats.

Carefully unscrew all the board mounting screws and remove the metal screen plate if present (in some Redmi Note 5A revisions it may be missing or replaced with a graphite screen). Then, taking the edge charge, slightly raise it and check if all the plumes are turned off. Pay special attention to the camera main module plume and display plume, which can be connected from the back side or at an angle.

⚠️ Warning: The motherboard is the most fragile element. Avoid bending and pressure on the center of the board where the processor and memory chips are located, as this can lead to microcracks in soldering (BGA) and the smartphone's downfall.

When removing the board, try to keep it horizontal so as not to damage the connectors. If the board gets stuck, check again for forgotten screws or entangled antenna contacts. Proper removal of the motherboard requires patience and precision of movement, since there are many small elements around it.

Replacement of the display module and battery

The two most common reasons for the Xiaomi Redmi Note 5A to disassemble are to replace a broken screen or worn-out battery. If your goal is to replace the display, then after removing the front bezels (which in this model often come with a touchscreen and a matrix), you need to disconnect the plumes from the motherboard. The screen is glued to the frame, so it will require heating to remove it.

To replace the battery, which in the Redmi Note 5A is removable, there is usually no difficulty. However, if the battery is swelled, it can be tightly pressed against the body or even glued. In this case, use a plastic card to carefully separate it from the body, avoiding punctures. Damage to the lithium-ion battery can lead to fire, so act extremely carefully.

• 🔥 Heat the screen perimeter with a hairdryer to temperature 60-80 degrees to soften the glue.
• 💳 Use a thin plastic card to separate the matrix from the frame.
• 🧹 Clean the frame of the remnants of old glue before installing the new module.
• 🔋 Check the contacts of the new battery for oxidation before installation.

When installing a new display module, make sure that the plumes are properly plugged into the connectors and fixed with pressing slats. Incomplete entry of the plume is a common cause of "dead" touchscreen or no image after assembly. Use original components or quality analogues, since cheap copies often have less resource and worse color reproduction.

💡

Quality cleaning of the frame from old glue is the guarantee that the new screen will hold reliably and will not backlash.

Assembly of the device and verification of functionality

The Redmi Note 5A is assembled in reverse disassembly, which means you first install the motherboard, plug all the plumes in, and screw the protective plates, and then you can install the battery and check the device's performance before you finally twist all the screws.

Turn on your smartphone and check the basic functions: sensor function, displaying colors on the screen, speakers, microphone, vibration and cameras. If everything works correctly, you can turn off the device and continue building. If problems are detected, you better fix them now, while the phone is not fully assembled.

Install the plastic safety panel by twisting all the screws into their seats. Make sure that no screw is left over - this may indicate an assembly error. Then gently snap the back cover, starting at the top and moving to the bottom, until a characteristic click around the perimeter.

The final stage will be the installation SIM-Successful assembly is not just about mechanically connecting parts, but also restoring the full functionality of the device. If you followed the instructions and used the right tool, your Xiaomi Redmi Note is a great choice. 5A ready for active operation.

⚠️ Warning: If the phone doesn't turn on after assembly, don't panic. Check if the battery plume and display plume are tightly connected. Often the problem is poor contact, not component breakdown.

💡

After assembly, wipe the body and screen with microfiber to remove fingerprints and dust accumulated during the repair process.
