Modern smartphones like the Xiaomi Redmi 5 Plus are highly integrated components, making them difficult to repair but feasible with experience. Disassembly of the device may be required to replace a broken display, worn-out battery or a failed charging connector. It is important to understand that any interference with the design of the gadget carries certain risks, so preparing the workplace and tools is a critical part of the process.
Before work begins, you need to free up space on the table, provide good lighting and, most importantly, completely turn off the device. Attempting to open a smartphone on can short-circuit and irreversible damage to the motherboard. In this guide, we will look at the stages of dismantling, paying special attention to fragile plumes and hidden screws.
Tools and workplace preparation required
A high-quality disassembly is impossible without a specialized tool that will avoid damage to the body and internal components. Standard set of home craftsmen is often insufficient, as the screws in smartphones have specific hats, and adhesive connections require careful heating.
First of all, you'll need a set of precision screwdrivers that includes the PH000 cross and PH00, and a slick screw for tweaking the elements. Equally important is a suction cup for neatly detaching the glass from the body without cracking. To work with small parts, you'll need plastic mediators or shoulder blades that don't conduct current or scratch the surface.
- 🔧 A set of screwdrivers with a magnetic tip for working with small screws.
- 🌡️ A hair dryer or heating platform to soften the glue under the display.
- 🧤 Antistatic bracelet to protect electronics from static electricity.
- 📦 Organizer for sorting screws of different sizes and types.
Particular attention should be paid to safety: working with lithium-ion batteries requires caution. If the battery is damaged or swelled, heating it can be dangerous, so in such cases you need to act as quickly and carefully as possible, avoiding punctures.
⚠️ Warning: Before starting any work, be sure to disconnect the smartphone from the charger and make sure it is completely off.Working with the device on when the back cover is removed can lead to a fatal short circuit.
The organization of the workspace is not just a matter of convenience, it's a necessity. Decompose all tools in accessibility, but in such a way that you don't accidentally swing them to the floor. Good lighting will allow you to see the microscopic connectors and the status of the contacts, which is critical when you build them.
Rear cover removal and primary access
The process of disassembling the Redmi 5 Plus begins with the removal of the rear panel, which is attached to the two-part adhesive around the perimeter of the body. Heating is a mandatory step, since cold glue holds the glass very tightly, and trying to tear it off by force will lead to glass breaking or deformation of the frame.
Use a hair dryer, evenly warming the perimeter of the back cover for 2-3 minutes. The temperature should not be extremely high, just warm the glass to a state where it is comfortable to hold in your hand, but the glue will become plastic. After heating, install a suction cup at the bottom of the back cover, closer to the logo, and pull up, creating a gap.
Insert a plastic mediator or a thin plastic card into the gap, drive the instrument along the edges, cutting the glue layer, and move slowly, avoiding sudden jerks, as the top of the case can be filled with plumes that go to buttons or antennas, which can be easily damaged by careless movement.
Once the lid is removed, you'll have access to the insides of your smartphone, and the first thing you need to do is remove the metal plate that covers the main nodes, and it's fixed by a few screws that you need to unscrew and fold into a separate cell of the organizer so you don't confuse it with the screws from the display module.
Disabling plumes and removing metal screens
The interior of the Xiaomi Redmi 5 Plus is densely filled with components, so access to most of them is blocked by metal screens. These screens not only protect the electronics, but also serve as radiators to remove heat from the processor and other heating elements.
Before removing any metal linings, make sure the battery is disconnected from the motherboard.The battery plume is usually on top and connected via a connector.Use a plastic blade to gently snap the connector, avoiding using metal tools that could damage the contacts.
Once the power is out, you can start dismantling the metal plates. The screws that hold them can be of different lengths, so it's important to remember or record their location. Often the screws under the camera are longer than those that attach protection to the processor.
- 📱 Carefully disconnect the main plume of the display, undercutting it with a nail or plastic spatula.
- 🔋 Remove the vibrator and speaker if they interfere with access to the screws of the central plate.
- 📷 Be careful with the main camera plume, it is very thin and easily breaks.
Pay particular attention to the plume connecting the mainboard to the lower board (where the charging connector is located) that runs under or along the battery and can be glued. Gently unzip it using blunt-ended tweezers, and disconnect it from the connector.
⚠️ Warning: Never pull the plumes. If the connector doesn't snap easily, check if there's a latch that needs to be bent up before you take it out.
Removing the screens opens up access to key components, and now you see the motherboard, the camera module, and the top of the body, and at this point, it's important not to lose small screws or damage the fragile paths on the boards.
Replacement of the battery and work with adhesive joints
The battery in the Redmi 5 Plus takes up a significant portion of the internal volume and is often attached to double-sided tape. Over time, the glue loses its properties or, conversely, hardens, making it difficult to remove the battery.
If you plan to replace the battery, first completely discharge the old one, if possible, to minimize the risks of retrieval.Heat the back of the smartphone (already without a lid) on a heating platform at a temperature of about 60-70 degrees Celsius for a few minutes.
What to do if the battery is swelling?
Use a thin plastic card or a special hood (pull-tab) if it was provided by the manufacturer (often green or blue tongues under the battery). Movements should be progressive, sawing, but without strong pressure to the center of the battery. Metal tools are prohibited, as a puncture of the cell will cause fire.
When installing a new battery, make sure that the contact pad at the bottom of the case is clean. If there is any old glue left, carefully remove it.The new battery usually has an adhesive base; remove the protective film and press the battery tightly against the case, holding for a few seconds to grasp.
Removal and replacement of the display module
The display module Xiaomi Redmi 5 Plus is a complex design consisting of a matrix, touchscreen and frame. In most cases, the repair module changes in the assembly with the frame, which greatly simplifies the process, since it does not require gluing the glass and bulking small parts.
To remove the module, you need to twist all the screws around the perimeter of the frame. The number can vary, so carefully examine all sides. After removing the screws, the module is held only by the adhesive layer and plumes.
| Type of component | Difficulty replacing | Risk of damage | The necessary tool |
|---|---|---|---|
| Back cover. | Low. | Tall (glass shattering) | Fryer, sucker. |
| Battery | Medium | Medium (puncture) | Plastic cards |
| Display module | Medium | Medium (trains) | Screwdrivers, shoulder blades. |
| Maternity fee | Tall. | Tall (electronics) | Complete set |
Carefully lift the module, making sure that all the plumes are turned off. If the module changes to the assembly with the frame, you need to move some elements from the old module to the new one: for example, the auditory speaker, proximity sensor and front camera, if they were not installed by the spare parts manufacturer.
💡
Before installing a new display, always conduct a test connection ("feed on weight") to make sure that the matrix and touchscreen are serviceable until glued.
When installing a new module, make sure that the plumes are stacked smoothly and not be framed. Incorrect stacking of the plume can lead to stripes on the screen or inoperability of the touchscreen after assembly.
Smartphone assembly and final check
The Xiaomi Redmi 5 Plus is assembled in reverse disassembly, but there are some nuances: it is important not to pull the screws, especially those that attach metal protection over the processor, so as not to damage the board, and you also need to make sure that all the connectors are snapped to a characteristic click.
Apply new glue or use special adhesive tapes (B-7000 or analogues) around the perimeter of the body before installing the back cover. Spread the adhesive evenly and press the cover tightly, fixing it with rubber bands for 15-20 minutes before initial grasping.
- ✅ Check the operation of all buttons (volume, on) for sticking.
- ✅ Make sure the speaker and microphone are not covered with glue or misaligned parts.
- ✅ Check Wi-Fi and cellular service as antenna contacts should fit tightly to the board.
Once assembled, turn the device on and do a full diagnostic, check the screen response, camera performance, charging and sound, and if all functions are working correctly, the repair is considered a success.
⚠️ Warning: If the smartphone doesn't turn on after assembly, don't try to charge it right away. Disassemble the device again and check to connect the battery plume and the main display plume. Often the problem lies in an incompletely inserted connector.
The final step is to clean the case of glue and fingerprints, and a clean and serviceable smartphone is ready for further use.
