When the beloved Xiaomi Redmi 5 suddenly stops responding to presses and refuses to start the operating system, it can be taken by surprise at the most inopportune moment.The screen remains black, the indicators are silent, and it seems that the device finally fails. However, before carrying the gadget to the service center, it is worthwhile to conduct a series of self-manipulations that often help to revive the smartphone without cost.
In most cases, the problem is not a fatal CPU or motherboard failure, but a software failure or a deep battery drain. Understanding the nature of the malfunction is the first step to successfully restoring the device. In this article, we will detail all the possible reasons why the Xiaomi Redmi 5 is not turning on, and provide step-by-step instructions for fixing each of them.
Many users panic early when they see a black screen, but statistics show that more than 70 percent of these cases are solved by software or simply replacing a charging cable. It is important to act consistently and carefully so as not to aggravate the situation. We will look at both simple "reboot" methods and more complex firmware procedures through the computer.
Diagnostics of hardware problems and power supply
The first thing to rule out when your smartphone doesn't react to the power is a power failure. Often, Redmi 5 doesn't turn on because the battery doesn't get power because of a damaged cable or adapter. Check if the charging light is on when you connect to the grid, even if the screen isn't lighting up.
If the indicator flashes red or does not light up at all, try replacing it. USB-The charging nest in the Redmi 5 can become loose over time, causing contact to disappear at the slightest displacement. Try to gently move the plug in the connector, holding the phone in a horizontal position.
In some cases, the problem is oxidizing the contacts or getting moisture inside the case. Even if the phone didn't fall into the water, high humidity in the room could lead to corrosion of the battery contacts. Oxidation creates high resistance, which prevents normal charge current.
⚠️ Warning: If you notice a bloated back cover or screen, do not attempt to charge the device at all.A bloated battery may ignite or explode when the current is applied.
To accurately diagnose the state of the battery, you can use a multimeter, if you have the skills to work with it. Normal voltage at the terminals of a serviceable Li-Ion battery should be from 3.7 to 4.2 Volts. If the device shows a value below 2.5-3.0 Volts, the power controller could block charging for safety reasons.
Software failure and system freeze
One of the most common reasons why Xiaomi Redmi 5 is not turned on is a critical failure in the Android operating system or the MIUI shell. The smartphone can be in a state of “cyclic reboot” or deep freeze when the processor is running, but the image on the display is not transmitted.
In this situation, a forced reboot helps, which requires holding and holding the power button for a long time — from 10 to 20 seconds. Some versions of the Redmi 5 require simultaneous clamping of the power buttons and increasing the volume.
☑️ Verification of the forced reset
If the phone vibrates but the screen is still black, it may be the display drivers or the screen module itself, so try to point the flashlight brightly at the screen when it vibrates: if you see a dim image of the interface, it means that the backlight of the display is burned, not the phone itself.
Often, the freeze occurs after an application update fails or dubious software is installed, in which case the system blocks the download to protect the data, and if the standard reboot does not help, you will need to switch to Recovery mode.
Enter Recovery and Hard Reset mode
Recovery mode is a special diagnostic interface built into the phone’s memory regardless of the main operating system. If the Xiaomi Redmi 5 does not turn on in normal mode, logging into Recovery often allows you to reset to factory settings and eliminate software conflicts.
To enter this mode, do the following: turn off the device completely (if it reacts), then press the power button and Volume Up at the same time. Hold them until the Mi logo appears, then release the power button, continuing to keep the volume.
| Action. | Navigation button | Confirmation button |
|---|---|---|
| Moving on the menu | Volume Up/down | - |
| Choice of menu item | - | Power button |
| Getting out of the regime | - | Reboot System |
| Data resetting | - | Wipe Data |
In the Recovery menu, the navigation is done with volume buttons, and the choice is confirmed by the power button. You need to find the Wipe Data or Clear User Data. Selecting this item will result in the complete deletion of all user data, so use this method only as a last resort.
What to do if the Recovery menu is in Chinese?
⚠️ Warning: Hard Reset permanently deletes all photos, contacts and apps. Before reset, make sure you have a backup of your data in the Mi Cloud cloud or on your computer.
After a successful reset, select Reboot or Reboot to System. The first download after the reset can last up to 5-10 minutes, as the system reconfigures the files. If the phone turned on and asked to choose a language, the problem is solved.
Fastboot mode and flashing the device
If the reset via Recovery did not help and Xiaomi Redmi 5 still does not turn on, it is possible that the system files of the bootloader are damaged. In this case, you will need to flash the device using a computer and the Mi Flash Tool utility.
To enter the Fastboot, turn off your phone and press the power button and Volume Down at the same time. The screen should show the distinctive Mi Bunny logo repairing the android, or the words FASTBOOT in orange.
💡
Use the original. USB-cable and connect the phone directly to the port USB 2.0 on the computer motherboard (back of the system unit) to avoid communication errors.
You will need ADB/Fastboot drivers, Mi Flash Tool and the firmware itself (ROM) for your model to run the firmware, and you should only download it from the official miui.com website, choosing either Recovery or Fastboot depending on the type of installation.

fastboot rebootFastboot's firmware completely erases memory and records a new copy of the system, a complex process that requires careful attention, and if the power is interrupted or the cable is removed during the recording process, the phone can turn into a brick, which can only be restored in a service center through a programmer.
It is important to note that the global firmware version in Chinese (or vice versa) may require an unlocked bootloader. If the bootloader is blocked, the Mi Flash program will give an error, and the phone will not turn on with the new firmware.
Display and plume problems
Sometimes the phone actually works: you hear notification sounds, you hear vibrations when you call, but the screen stays black. In the case of Redmi 5, this often indicates physical damage to the display matrix or the departure of the plume. The model has a modular design where the touchscreen and the display can be soldered or connected by a plume.
If the phone fell or was severely compressed, the plume could move away from the connector on the board. To test this hypothesis requires partial disassembly of the device. Once you remove the back cover, you can gently turn off and reconnect the display plume, making sure that the contacts are clean.
- 🔌 Connector waste: Frequent problem after falls, requires reconnection of the plume.
- 💥 Broken matrix: Even without cracks in the glass, the internal structure could have been broken.
- 🔋 Failure of the power controller: voltage on the backlight is not applied.
It's also worth checking the battery connector. When hit, the battery connector might have shifted, and the phone is running off the grid, but it can't see the battery, which interrupts the power cycle.
💡
If the phone is defined as a device when connected to a computer (the USB connection sound is emitted), but the screen is black, the display or its plume is most likely faulty.
When you need to go to the service center
There are a number of symptoms in which self-repair Xiaomi Redmi 5 is not only useless, but dangerous.If after all the manipulations with the firmware and reset the phone does not give signs of life, probably the motherboard failed.
One of the common hardware problems with this model is the chip or memory chip toppling due to overheating or mechanical stress, requiring professional equipment to perform the rebolling procedure (replace the solder under the chip) in a thermal-profile furnace.
⚠️ Warning: Attempts to heat up the board with a hairdryer at home often lead to the final failure of the device.
Also, the service should be contacted if the phone is identified by the computer as an unknown device with an error code, or if the smell of burning comes from the speakers or the charging connector. In such cases, the cost of repair can be comparable to the price of a used device, and it is more advisable to consider buying a new one.
Remember that the Redmi 5 is a device that was released a few years ago and its components can be exhausted. Natural battery wear and memory degradation are a natural process for any electronics.
