Broken display glass or vertical stripes on the matrix are typical problems faced by owners of the Xiaomi Redmi 5 Plus smartphone after several years of active use. The device, released in late 2017, is still popular due to its balanced characteristics, but its housing design involves the use of adhesive joints, which complicates the process of self-repair.
Before you start dismantling, it is necessary to clearly understand that the replacement of the touchscreen and matrix in this model is only made in the assembly.Separate glass gluing at home is impossible and requires specialized equipment to separate the layers. If your Redmi 5 Plus has ceased to respond to touch or the image is completely absent, you will need a new assembly module.
In this guide, we will discuss in detail the procedure for replacing the display, paying special attention to working with plumes and careful handling of plastic elements of the case. The correct approach to repair will not only restore the gadget to its original appearance, but also avoid additional damage to internal components, such as a charging plume or speaker.
Tools and workplace preparation required
To work with the Xiaomi Redmi 5 Plus, you will need a set of precision screwdrivers, since the screws in this model come in different sizes and types of slits. The standard toolkit usually includes cross screwdrivers of different diameters and a plastic blade.
Special attention should be paid to heating elements. The back of the phone is glued around the perimeter, and to remove it safely, you need to soften the adhesive layer. The use of a hair dryer or heating panel is a prerequisite for maintaining the integrity of the metal body and preventing cracks in the glass.
- 🛠️ Screwdriver Set (Cross Phillips #00, #0)
- 🔥 Hair dryer construction or household heating pad (temperature up to 100)°C)
- 🧤 Suction and mediator (plastic card)
- 🧲 Magnetic screw-sorting mat
⚠️ Warning: Do not use a knife or sharp metal objects to pluck the lid, as this may damage the antenna inserts or battery failure.
Prepare a clean, well-lit workplace. Small parts like screws and plugs are easily lost, so having a magnetic mat or cell container will make the assembly process much easier. It is also recommended to check the new display module for external defects before starting work.
☑️ Preparation for repairs
Removal of the back cover and removal of the battery
The Redmi 5 Plus disassembly process begins with the extraction of the tray for the SIM-This is a standard safety procedure to avoid short circuits when the device is accidentally turned on.
Heat the edges of the phone evenly for 2-3 minutes. The temperature should not be extremely high so as not to damage the internal components, but sufficient to soften the glue. Carefully insert the suction cup into the bottom of the lid and, pulling up, create a small gap where you immediately insert the plastic card.
Swipe the card or mediator around the perimeter of the case, gradually separating the lid from the frame. Take your time feeling the resistance of the glue. Once the lid is removed, you will see a battery pack that is also attached to double-sided tape. Use a plastic blade to remove it, putting the battery on for special notches.
Why can't you pull the battery?
The critical step is to disconnect the battery plume from the motherboard, before removing the plastic protective bar that is screwed up by multiple screws, and only after the power is turned off can you safely continue working with other components.
Disassembly of the main board and disconnection of plumes
Once the device is de-energized, the main nodes are dismantled. The Xiaomi Redmi 5 Plus motherboard is covered with a metal screen and plastic plugs. You will need to carefully inspect the device and unscrew all the visible screws, fixing the board and modules.
Notice the plumes that connect the display to the board. They can be located in different places depending on the modification, but most often they are at the top, carefully bend the locking connectors and extract the plumes with tweezers.
| Component | Type of attachment | Features of withdrawal |
|---|---|---|
| Maternity fee | Screws + plumes | Requires removal of all side covers |
| Display plume | ZIF-connector | Bow the black or white bar |
| Management fee (lower) | Screws + plume | Connected to the charging connector |
When working with connectors, use antistatic gloves or dielectric-coated tweezers. Static electricity can damage sensitive electronics. If the screws are too tight, use a quality screwdriver to keep the slime from licking the slime.
⚠️ Warning: The plumes in Redmi 5 Plus are quite thin and fragile.Don't put too much effort into bending or detaching them, as it's almost impossible to repair a broken plume.
💡
Take a picture of all the screws and plumes before you remove them, which will help you avoid confusion when you reassemble them, especially if you don’t have a magnetic mat.
Removal of the old display module
When the motherboard and the bottom board with the charging connector are disconnected, you can start removing the display itself. In the Redmi 5 Plus model, the screen is glued into the front bezel, which in turn can be part of the overall design or a separate element, depending on the version of the case.
If you bought a module assembled with a frame, the task is simplified: you only need to transfer all the internal components (motherboard, speaker, vibrator, lower board) from the old broken module to the new one. If the module is frameless, you need to carefully unstick the old screen from the metal base.
It's going to require heating again. Warm up the front of the phone, trying not to overheat the matrix if it's still partially functioning. Use a suction cup and a mediator to separate the glass from the body. Move slowly, cutting through the adhesive layer.
- 🌡️ Evenly warm the face panel with a phenome
- 🧩 Separate the dynamic module from the body
- 🧹 Clean the frame from the remnants of old glue
- 🖐️ Degrease the surface before installing a new module
Cleaning the frame of the old glue is a critical step, and the surface must be perfectly smooth and clean, so that the new module will lie flat and hold securely, and use isopropyl alcohol and soft fabric for final processing.
Installation of a new screen and assembly of the device
Before the final assembly, test the new display, plug the plumes into the motherboard, plug the battery temporarily, and turn on the phone, check the touchscreen, the presence of broken pixels, and color transmission.
If everything is working correctly, turn off the power and proceed to install. Apply a new layer of B-7000 glue or use pre-applied glue on the module (if any). Carefully combine the module with the frame and press tightly around the perimeter.
The assembly is done in reverse order, the internal components are installed first, the boards and the protective slats are screwed up, and the special attention is paid to the stacking of the plumes, they should not be clamped or broken.
Assembly sequence:
Installation of speaker and vibromotor
Installation of the motherboard
3. Connecting the display and touchscreen plumes
4. Installation of the lower board (USB)
Fixing of protective metal slats
Connecting the battery
7. Installation of the back coverWhen twisting screws, observe a moderate puff moment. Too much pressure can damage plastic threads or crack glass. Make sure all screws fall into place, especially those that fasten the charging connector.
⚠️ Warning: Do not turn on the phone immediately after assembly without mounting the back cover.This can lead to short circuit if metal elements of the cover touch the contact board.
💡
Quality frame cleaning and proper plume stacking are two of the main factors of success when replacing the screen with Redmi 5 Plus.
Typical errors and operating tips
Even with careful follow-up, beginners often make mistakes, and one of the most common is that the plume is damaged when the back cover is installed. If the lid is difficult to get up, don't push it, but check if all the components are properly stacked.
Another common problem is poor touchscreen contact after assembly, which can be caused by dust falling under the connector or insufficient latching of the lock, in which case the disassembly procedure must be repeated.
After changing the screen, allow the glue to dry for 1-2 hours before actively using the phone or putting on a case, which will ensure maximum strength of the connection and prevent the exfoliation of the edges in the future.
- 🚫 Do not use your phone while drying glue
- 🧼 Regularly wipe the screen with a soft cloth
- 📱 Use protective glass for prevention
- 🔋 Watch the temperature of the device when charging
Compliance with these simple rules will extend the life of your Xiaomi Redmi 5 Plus and the new display. Electronics repair requires patience and accuracy, but the result is worth it.
