How to disassemble Xiaomi Redmi 5 Plus: step-by-step instructions

Many owners of the popular budget smartphone Xiaomi Redmi 5 Plus (also known as Redmi Note 5 Pro in the global version) sooner or later face the need to open the device. This can be due to the replacement of a broken display, worn-out battery or failure of the microphone. Self-disassembly requires accuracy, understanding of the design and the presence of a special tool, but it is quite feasible at home with the observance of technology.

But you have to understand that any interference with the internal structure of the gadget carries risks. Unlike modern models with adhesive frames, here the design is more friendly to repair, but has its nuances. The main difficulty lies in the correct snapping of the plumes without damaging the contact areas on the motherboard. Before you start, be sure to evaluate your skills and make sure that you have the necessary tools at hand.

Preparation of the workplace and tools

The Xiaomi Redmi 5 Plus’s high-quality disassembly begins well before the first movement of the screwdriver.You’ll need to organize a clean, well-lit workplace where nothing will distract from the process. Small screws and parts are easy to lose, so it’s recommended to use a magnetic mat or cell containers to sort the fastener by dismantling stages.

The toolkit should be minimally sufficient, but of high quality. Cheap metal blades can scratch the body or even damage the screen, so it is better to use specialized plastic.

• 🛠️ Set of screwdrivers (cross Pentalobe and Phillips) for screws of different caliber.
• 🔧 Plastic mediators or suction cup to open the body.
• 🧤 Antistatic gloves to protect electronics from static voltage.
• 💡 Lupus or magnifying glass for working with small connectors.

Pay special attention to safety. Although battery voltage is not fatal, short circuiting can cause fire or damage to the board. Disconnect the battery as soon as access to its connector becomes available. This is the golden rule of repairing any portable electronics that will keep the device from burning out the power controller.

Removal of the back cover and primary access

Unlike the flagship models with glass panels, the back cover of the Redmi 5 Plus is made of metal and is mounted on latches around the perimeter. SIM-This is a must-do step, and ignoring it can damage the contacts inside the slot when you try to lid the slot.

Using a plastic blade or a mediator, walk gently around the perimeter of the device. Don't put too much effort into it: you should hear the characteristic clicks of the clips opening. Move from the bottom end, gradually moving to the top, where there are usually more latches.

⚠️ Warning: Do not use metal knives or blades to lid the metal may slip and damage the display or breach the battery, causing it to ignite.

Once all the latches around the perimeter have been snapped, don't rush to open the lid abruptly. Inside, there may be plumes attached, such as from the fingerprint scanner button (if the model supports this feature in your version) or antenna contacts. Carefully lift the edge and visually inspect the insides for connectors.

Dismantling the main board and components

When you remove the back cover, you get access to the main interior, and it's where the motherboard, the battery, and the bottom board with the charging socket are located, and the first thing you need to do is remove the plastic protective lining that covers the connectors of the display and touchscreen plumes, and it's usually secured with multiple screws.

When you unscrew the fasteners, you gently remove the metal plate, you'll see wide plumes underneath, you'll use a plastic blade to turn them off, you'll need to move upwards, not sideways, so you don't damage the contacts, and once you turn off the plumes, you can start removing the board itself.

The board is attached with multiple screws of different lengths. It's critical to remember or write down which screw was twisted from where. Wrapped a long screw into a short hole can break through the tracks on the board, making repairs economically inefficient. Once all the screws are twisted, the board is easily retrieved with tweezers.

Replacement of the battery and lower board

The battery in the Redmi 5 Plus takes up a significant part of the body volume and is usually glued to the frame with double-sided tape. To remove it, you can not use sharp objects. It is recommended to gently tuck the edge of the battery with a plastic card or use special heating (dryer) at a minimum temperature to soften the glue.

The lower board, where the Micro-USB connector (in some versions) or Type-C, as well as the main speaker, also requires careful attention. Often, an antenna cable (coaxial wire) passes through special grooves and is attached with latches, which must be flicked with tweezers before removing the board.

When installing a new battery, make sure the contact pad is clean. If the old battery had a charge controller soldered to the board, soldering it requires soldering iron and flux skills, and in most cases, the entire battery module changes.

Assembly of the device and verification of functionality

The assembly is done in reverse disassembly, but before you finally snap the back cover, you need to do an initial health check, plug the display and touchscreen plumes, then press the switch on. If the screen catches fire and reacts to touch, you can continue.

Put all the screws in their places, keeping the length and type of thread. Don't pull the screws: plastic can crack, metal can break the thread. The effort should be moderate, sufficient to fix the components. Pay special attention to the screws around the connectors.

The final step is to install the back cover, combine the protrusions at the top of the body (near the camera) and press the edges until you click the characteristic perimeter, and make sure there are no gaps through which dust can penetrate.

💡

The main check before assembly is a touchscreen and sound test, and if a defect is found after full assembly, you will have to disassemble the device again, which increases the risk of damage to the components.
