How to disassemble Xiaomi Redmi Note 5 Plus: a detailed guide

Smartphone Xiaomi Redmi Note 5 Plus has proven itself as a reliable device, but even the highest quality equipment over time requires maintenance. Most often users are faced with the need to replace a broken display or battery. Self-disassembly allows you to save a lot of money, but requires accuracy and understanding of the internal structure of the gadget.

Before you start dismantling, it is important to realize that opening the case automatically voids the official warranty. If your device is still in warranty service, it is wise to contact an authorized service center. However, if the warranty has already expired or the case is not warranty, you can proceed with self-repair.

In this article, we will take a closer look at each step of disassembling the popular Redmi Note 5 Plus, learn about the tools, sequences and hidden nuances that beginners often miss.

Preparation of the workplace and tools

The Redmi Note 5 Plus is not a good disassembly without proper preparation. You need to organize a clean, well-lit space where small screws will not get lost in the pile of carpet or dust. The ideal option is an antistatic mat, but a regular table with a smooth surface will also work.

The minimum toolkit is required, which can be purchased from any electronics store or ordered online. The main tool will be a set of screwdrivers, including cross bits of Phillips size #00 and #0.

• 🔧 Plastic spatula (mediator) or suction cup for neat opening of the case without scratches.
• 🔧 Tweezers with curved ends for extracting small details and working with plumes.
• 🔧 A hair dryer or thermoribbon for pre-heating of the adhesive layer (if the screen is already broken).
• 🔧 Containers for sorting screws, as they can differ in length.

Pay special attention to safety. Be sure to turn off your smartphone before you start work. If the screen is broken and does not respond to touch, try pressing the power button and the volume button for a forced reboot, then wait for the switch to turn off.

⚠️ Note: Do not use metal tools (knives, needles) to smack the lid or screen, as there is a high risk of damage to the battery or plumes, which can lead to fire.

Removal of the back cover and primary access

Xiaomi Redmi Note 5 Plus has an all-metal body, making the opening process slightly more difficult than plastic counterparts. The rear panel is attached not only to the screws, but also to the adhesive base around the perimeter. You need to start by twisting the two lower screws located on the sides of the charging connector.

Once the screws are removed, take the suction cup and attach it to the bottom of the back cover. Pull it a little over yourself, create a gap, and insert a thin plastic blade in there. Driving the tool along the side faces, gradually releasing the clips. The movements should be sliding, without sharp jerks.

When the perimeter is passed, don't try to pull the lid off sharply. There may be resistance at the top, closer to the camera module. Carefully lift the edge and inspect the insides. Make sure the fingerprint scanner plume (if it is present and connected to the board) isn't stretched, although it often comes in a separate plume in this model.

Dismantling the protective plate and disconnecting the plumes

When you remove the metal back, you'll see the interior layout, and the central part is a large plastic or metal plate covering the main components, and it's fixed by many screws of different sizes, so it's important to remember their location.

Use the Phillips #00 screwdriver to unscrew all the visible screws on the plate. Notice the screws in the corners and around the main camera module. After removing them, gently tuck the plate with a plastic blade and remove it. Now access to the motherboard and battery is open.

The first and most important thing is to turn off the battery plume, and then find the battery connector on the board and gently disconnect it with a plastic blade, and this will turn off the device and keep the electronics from shorting as you go along, and then you can turn off the other plumes, the display, the cameras and the buttons.

When you turn off the plumes, be gentle. The connectors in the Redmi Note 5 Plus are tight enough, but fragile. Pull them up from the bottom or side, avoiding pressure on the circuit board itself. If the connector doesn't lend itself, check if there's a metal bracket on the top.

Removal of the battery and replacement of components

The battery in Xiaomi smartphone is fixed to two-way scotch. It requires heating to safely extract it. Use a hair dryer to warm up the back of the case (if the lid is still in place) or a front panel (if you shoot through the screen) in the battery area to a temperature of 60-70 degrees.

After warming up, use a plastic card or a special spatula to ignite the edge of the battery. Move slowly, helping yourself to heat. It is strictly forbidden to puncture the battery or bend it, as this will cause the battery to fail and possibly ignite the lithium cell.

If you change the screen, after you turn off the plumes and remove the frame (which is held on the glue and screws around the perimeter), the display module can be separated from the body. The new screen is installed in the reverse order: first connect the plume to the circuit board off, then test the work, and only then fix with glue.

Assembly of the device and check of performance

The Xiaomi Redmi Note 5 Plus is assembled in reverse order. Set a new battery or screen with the plumes attached beforehand. Make sure all connectors fall into place with a characteristic click. A loosely inserted plume is a common cause of a broken touchscreen or microphone.

Tighten the protective plate, keeping the screws in order. Long screws can not be screwed into short holes - this can damage the board or the body. Tighten the screws without undue effort, so as not to break the thread in the metal bushings.

Before the final back cover sticker, do the initial test. Connect the battery and try to turn on the smartphone. Check the sensor, speakers, microphone and cameras. If everything is working correctly, apply a new glue around the perimeter of the lid and press it tightly, locking it with rubber bands for 15-20 minutes.

💡

Use the B-7000 glue to fix the lid – it remains elastic after drying, making it easy to open the phone in the future, unlike superglue.

Typical errors and precautions

Beginners often make mistakes that lead to additional breakdowns, and one of the most common is damage to the backlight plume when the screen is taken off carelessly, and this plume is very thin and runs close to the edge of the matrix, so maximum concentration is required.

Another mistake is ignoring the heat when removing the battery, trying to uncook a cold battery by force causes it to deform, and a deformed battery is dangerous to use and must be disposed of, which will incur additional costs.

Also worth remembering is static electricity. Although modern boards are protected, there is a risk of breakdown. Try not to touch the contacts on plumes and boards with your fingers. Work in dry rooms and use antistatic gloves if you have any.

⚠️ Warning: If the phone doesn't turn on after assembly, don't panic. Check if the battery plume is connected and if it sits tightly in the connector. Often the problem lies in poor contact.
