How to open Xiaomi Redmi Note 5: full disassembly instructions

Smartphones line Redmi Note from Xiaomi deservedly popular due to the balance of price and quality, but even reliable devices over time require maintenance. Owners of the Redmi Note 5 (also known as Redmi 5 Plus in some markets) often face the need to replace the battery, broken display or clean the speaker from dust. Self-opening the case allows you to save a significant amount on the services of the service center, but requires accuracy and understanding of the device gadget.

The process of dismantling components in this model is not trivial, since the manufacturer uses adhesives to fix the main elements. Incorrect opening can lead to damage to the plumes, cracks in the glass or, in the worst case, to the fire of the lithium polymer battery. Before starting work, you need to carefully prepare the workplace, provide good lighting and stock up with a specialized tool to minimize the risks.

In this guide, we will take a detailed look at each stage of disassembly, from the extraction SIM-You'll learn about hidden screws, the adhesive layers and the methods of safely warming the case. 80-90 Celsius, which softens the glue and allows you to open the smartphone without chipping. Following the instructions will help you successfully repair or replace components.

Preparation of the workplace and the necessary tool

Quality preparation for repair is the key to the success of the entire operation. To disassemble the Xiaomi Redmi Note 5, you will need not only a standard set of screwdrivers, but also specific devices that will help work with adhesive joints. Ignoring this stage often leads to the process being delayed or leads to the breakdown of fasteners.

The main tool will be a set of precision screwdrivers, including cross bits size PH000 and PH00, also indispensable plastic mediators, a sucker to lift glass and a thin metal scalpel or blade to cut glue. Remember to tweezers with curved ends for working with small plumes.

  • 🛠️ A set of precision screwdrivers (cross and flat)
  • 🔥 Hair dryer or thermoplatform for heating the body
  • 💳 Plastic cards or mediators for opening
  • 🧲 Magnetic mat or organizer for screws
  • 🧤 Antistatic gloves and suction cup

Special attention should be paid to the heating source. Using a household hair dryer may not be effective enough, so it is better to use a temperature-adjusted building hair dryer or a special thermoplatform. Overheating of the matrix or battery is not allowed, so temperature control is mandatory. All screws are better sorted immediately by disassembly stages, since they can have different lengths and threads.

Primary actions: extraction of the tray and heating of the case

The first step in the process of how to open the Xiaomi Redmi Note 5 is to remove the tray for the device. SIM-This must be done before heating, because the expansion of metal and plastic at high temperatures can jam the tray mechanism and you can't remove it without damage. Use a special paper clip or a thin screwdriver sting to press into the tray hole.

⚠️ Warning: Before starting any work, be sure to turn off the smartphone. Attempting to disassemble the enabled device can lead to a short circuit on the board and failure of the power controller.

Once the tray is removed, you need to warm up the perimeter of the back cover. The glue that locks the glass to the frame is very strong at room temperature. 2-3 minutes, keeping the hair dryer at a distance 3-5 Do not hold the jet of hot air for a long time at one point, so as not to damageOLED-matrix or not to overheat the battery.

The glue test is done by putting a suction cup or mediator into the corner of the body, and if the glass is slightly amenable to the characteristic crackling of the adhesive, you can open it. If the lid is dead, you should repeat the heating procedure. Patience is more important than strength at this stage.

Removing the back glass panel and accessing the insides

After sufficient warming, insert a thin mediator or blade into the gap between the frame and the glass at the bottom of the device. Carefully guide the tool along the perimeter, cutting the adhesive layer. Do not plunge the tool deep, so as not to damage the fingerprint scanner plume that runs close to the edge, or break antenna wires.

Go around in a circle, gradually peeling off the glass. Pay special attention to the top, where the camera module and flashes are located, where the glue can be applied more abundantly. When all sides are passed, gently lift the back cover. Don't pull sharply, check if there are any glued areas left.

  • 📱 Start the opening from the lower corner at the charging connector
  • 🔪 Move the blade parallel to the plane of the screen
  • ⚠️ Go around the camera area and the fingerprint scanner
  • 👐 Use a suction cup to create glass tension

Once the lid is removed, you will have access to the battery, the main camera module and the bottom board, and notice the black plastic plugs covering the screws and plumes, which may also need to be carefully tampered with and removed, and at this point you can see the fingerprint scanner plume, which requires special care when you go ahead.

What to do if the glass cracks at the opening?
If the back window cracked but didn't crumble, you can gently glue it with transparent tape on the outside so that the shards don't get inside. Full repairs will require replacing the back cover as structural integrity is lost. New fiberglass can be ordered separately or removed from the donor device."> Battery removal and disconnection of the plumes In the Redmi Note 5 model, the battery is glued to the body quite firmly, which is a common practice for modern smartphones. Before trying to remove the battery, it must be switched off from the motherboard. To do this, use a plastic jacket, a plug-in, and a plug-in. Warm up the battery area a little bit (no more). 60-70 Pull the tongue if you have one, or gently smack the battery with a flat tool from different sides, and it is strictly forbidden to pierce or bend the battery, as this will cause it to ignite. Component Type of fastening Risks when removing Tool Back Cover Glue around the perimeter Broken glass, torn plume Fen, mediator Battery Bilateral Scotch Puncture, fire, suction swelling, heating the Motherboard screws + plume break, screwdriver board chip, Screen tweezers (module) Clay + Frame Broken matrix, cracks Thermoplatform After removing the battery, examine its condition. If you plan to install a new battery, be sure to apply a new layer of glue or double-sided tape to fix it. Old glue is better removed carefully with alcohol or a special solvent so that the new battery is kept secure and does not hang inside the case. Working with the motherboard and camera module The motherboard in Xiaomi Redmi Note 5 is located at the top of the device and is closed with a metal screen and plastic casings. To access the main connectors, you need to twist all the visible screws that hold the protective plates. Usually there are about 10-12 pieces, and they can be of different lengths, so remember which screw from where. After removing the protection, access to the display plumes will open up, and the tap is made from the main cable, then the main one is made from the cable. The main camera module is mounted with screws and sits tightly in its nest. When removing, be careful with the lens — do not touch the lens with your fingers, so as not to leave fat marks, which will then affect the quality of the photo. The camera plume is very thin and easily tears when handled carelessly. 📸 Turn off the main camera plume first 🔌 Carefully disconnect the wide plume of the display 🔩 Remember the location of the board protection screws 🧼 Clean the camera lenses with microfiber only ⚠️ Warning: When removing the motherboard, make sure that the antenna wire (usually black or white coaxial cable) running from the board to the bottom of the case is turned off. Replacement of the display and assembly of the device The most difficult operation is often to replace the display module. In the Redmi Note 5, the screen is glued to a frame, and it requires either unsticking the old broken module (which is very time-consuming and risky), or re-gluing the entire frame. The easiest way to buy a module assembled with a frame and transfer all the components: board, battery, cameras and charging boards. The repainting process takes longer, but ensures no gaps and dust. After transferring all components to a new screen frame, check the operability of the touchscreen and images by connecting the plumes before finally fixing the cover. Make sure all screws are twisted and the plumes are inserted into the connectors before you click. The final stage of assembly is to glue the back cover. Clean the frame of the residue of the old glue with alcohol. B-7000 or T-7000 perimeter. Press the lid and fix the device with rubber bands on 1-2 Don't turn on the phone right away, let the glue grab. 💡Quality assembly depends on the purity of the adhesive surfaces and the right timing of the screws tightening. Don't pull the screws over to avoid ripping the threads in the plastic bushings. How long does it take to completely disassemble the Redmi Note 5? For an experienced master, the process takes 20-30 A newcomer doing this for the first time should pawn. 1-1.5 You can open the phone without a hair dryer, and you can theoretically use isopropyl alcohol, which is run under the lid with a syringe, but without heating, the glue remains very rigid, and the risk of breaking the glass or damaging the frame increases significantly. Which glue is best used for assembly? The optimal choice is silicone-based adhesives like the B-7000 or E-8000. They remain elastic after drying, which will make it easier to re-disassemble in the future, unlike superglue. What if the phone doesn't turn on after assembly? First, check the battery plume and main plume connection. Make sure the battery is charged. If the phone vibrates, but the screen is black - possibly damaged by the display plume or the screen itself.
