In this article, you will find a step-by-step guide with photos of key steps, a list of tools you need and tips on how to avoid typical errors. We will also tell you which parts of the Redmi Note 5 most often fail and how to replace them without risking to the rest of the components. If you have never taken out a smartphone, do not worry: with the right approach, even a beginner will cope with the task.
⚠️ Important: Disassembly of the smartphone Xiaomi Redmi Note 5 voids the warranty (if it is still valid).Be sure before work that the device is turned off and the battery is charged no more than 25% - this will reduce the risk of fire in case of accidental closure of contacts.
Preparation for disassembly: tools and security measures
Before you start disassembling, prepare the workspace and tools.The Redmi Note 5 has a plastic case with a metal frame, but that doesn't mean it's easy to disassemble without specialized fixtures.
- 🔧 Set of screwdrivers (cross-haul) PH00, flat 1.5 mm, five-pointed Y00 screw-tray SIM-map).
- 📱 Plastic mediators or shoulder blades (for separation of the body without scratches).
- 🔥 Dryer or thermoair station (to soften the glue under the screen if replacement is required).
- 🧲 Magnetic mat or container (to avoid losing small screws).
- 🔋 Insulation or capron tape (for fixing plumes during work).
Work on a clean desk with good lighting. It is advisable to use an antistatic bracelet to avoid damage to the chips by static electricity. If the bracelet is not, regularly touch metal objects (such as the computer system unit) to remove static charge.
⚠️ Warning: Do not use metal blades to separate the case - they can damage plastic latches inside the smartphone. Also avoid excessive heat with a hairdryer: temperature above 80°C can deform plastic or damage the battery.
Removal of the back cover: hidden latches and glue
The Redmi Note 5 body is mounted on a combination of glue and plastic latches. To remove the back cover, start with the tray. SIM-And you can take it out with a paper clip or a special key, and you'll see two screws under the tray, and you'll unscrew them with a cross screwdriver. PH00.
Next, warm up the hair dryer of the edge of the body around the perimeter for 1-2 minutes, holding the device at a distance of 10-15 cm. The glue will become more elastic, and the cover will be removed easier. Insert a plastic mediator into the gap between the body and the frame (start at the bottom edge where the USB-C connector is located) and carefully guide it along the perimeter, snapping the clips.
⚠️ Warning: Don't use excessive force when the lid is removed, because there are fragile antenna contacts inside that can be torn off. If the lid doesn't lend itself, warm up the problem area with a hair dryer again.
After removing the cover, you will see:
- 🔋 Battery with connected plume.
- 📷 Metal framed main camera module.
- 📶 Antenna contacts (black and gold stripes at the edges).
- 🔊 The speaker and microphone at the bottom.
☑️ Preparation for lid removal
Disconnection of the battery and work with plumes
The first thing you need to do after you take off the lid is to turn off the battery, and the battery plume is on the top of the battery, and it's attached to the motherboard with a small connector, and you need to gently put a plastic blade on it, pull it up, and never disconnect the plumes with metal tools, which can close the contacts and put the board out of action.
Now you can start to disable the remaining plumes:
- The plume of the display module (wide, in the center).
- The plume of the touch glass (thin, next to the display).
- Camera plume (black, in the upper left corner).
- The power button/volume loop (small, right).
⚠️ Attention: Redmi Note 5 plumes are extremely fragile. If you feel resistance when you shut down, don't pull. It may be an extra glue or a latch on the plume.
For convenience, take a picture of the location of the plumes before turning off or take notes on paper, which will help avoid confusion when reassembling.
What to do if the plume is broken?
Extraction of motherboard and child modules
Once all the plumes are turned off, you can remove the motherboard, which is mounted on 10 to 12 screws of different lengths (remember which screw was twisted from where!) Use a magnetic mat so you don't confuse them when you build them. The screws under the board can hide under stickers - gently tuck them in.
Table of screws Xiaomi Redmi Note 5:
| Type of screw | Size | Number of | Location |
|---|---|---|---|
| Cross PH00 | 3.5 mm | 6 | Perimeter of the charge |
| Cross PH00 | 2.5 mm | 4 | Under the battery. |
| Five-pointed Y00 | 1.5 mm | 2 | Tray SIM-map |
| Flat. | 1.2 mm | 2 | Camera attachment |
After removing all screws, carefully gently apply the board with a plastic blade from the edge where the USB-C connector is located. Don't pull the charge for the corners - this can damage the soldering contacts. If the board does not lend itself, check if all screws are twisted (sometimes they are hidden under stickers or plumes).
⚠️ Warning: The Redmi Note 5 board has a Qualcomm Snapdragon 636 chip, which is sensitive to static electricity.
💡
If the screw fell to the floor and was lost, do not use a screw of another length instead - this can damage the board when tightening. It is better to temporarily fix the board with tape or buy a new set of screws (they cost a penny).
Replacement of common parts: screen, battery, camera
Most often, three components fail in Redmi Note 5: the screen (due to falls), the battery (after 2-3 years of operation), and the camera (pollution or damage to the module).
1. Screen replacement
The Redmi Note 5 display module is glued around the perimeter to remove it:
- Warm up the screen with a hair dryer (temperature 60-70 ° C) for 3-5 minutes.
- Tap the glass with a plastic blade from the bottom edge (where the speaker is located).
- Carefully drive the blade along the edge, separating the glue. Do not delve the blade more than 2 mm - there are plumes under the screen.
The new screen is set in reverse order, use fresh glue (e.g. B-7000) and press the module evenly for 10-15 minutes.
Replacement of the battery
The battery in the Redmi Note 5 is glued to the body to extract it.
- 🔥 Warm up the battery with a hair dryer (not higher than 50)°C!).
- 🧹 Tap the battery with a plastic shovel on either side and pull up.
- 🔋 Do not use the battery, it can cause a fire!
Stick the new battery to a double-sided tape or special glue for batteries.
3. Replacement of the camera
The camera module is mounted with two screws and a plume. Unscrew the screws, unplug the plume, and remove the camera. When you install a new one, make sure there is no dust under the module, it can get inside the lens.
💡
When replacing a screen or battery, always use new glue. The old glue loses its properties after heating and will not provide reliable fixation.
Frequent Mistakes and How to Avoid Them
Even experienced craftsmen sometimes make mistakes when disassembling the Redmi Note 5, and here are the most common ones and ways to prevent them:
- 🔌 Train damage – use only plastic tools and do not pull the plumes behind the wires.
- 🔥 Overheating the board with a hairdryer – keep the hairdryer at a distance of 10-15 cm and do not heat one area longer than 30 seconds.
- 🔋 Short circuit – before work, turn off the battery and do not touch the contacts with metal objects.
- 📱 Loss of screws – use a magnetic mat or container with cells.
Another common problem is the wrong build, when the smartphone doesn't turn on or all the functions aren't working after the repair.
- Check all the plumes for the reliability of fixation in the connectors.
- Make sure all screws are twisted (but not pulled!).
- After assembly, turn on the smartphone and check the work of all sensors (sensor, gyroscope, camera).
If the Redmi Note 5 doesn't turn on after assembly, but the indicator is on when charging, the problem is most likely the power plume or the battery. If the indicator doesn't burn, check the motherboard for short circuit.
Reverse Assembly and Testing
The assembly of the smartphone is carried out in reverse order, but with some nuances:
- Start by installing the motherboard and spin all the screws (don’t forget the ones hidden under the stickers!).
- Connect the plumes in the following order: battery → display → sensor → camera → buttons.
- Lay the plumes so that they do not overflex and do not touch the sharp edges of the body.
- Stick the back cover, evenly pressing it around the perimeter (you can use a heavy book as a press for 10-15 minutes).
After assembly, turn on the smartphone and check:
- 📱 Sensor operation (swipe your finger across the screen).
- 📷 Camera (take a test shot).
- 🔊 Speaker and microphone (call another phone).
- 📶 Network and Wi-Fi (Make sure antennas are connected correctly).
⚠️ Warning: If the smartphone overheats or discharges quickly after assembly, check if the screws on the motherboard are tightened.Excess pressure can cause short circuit or chip damage.
💡
After replacing the battery or screen, the smartphone may require calibrating the battery. To do this, completely discharge it, and then charge it to 100% without interruption.
