When your favorite smartphone suddenly stops responding to your usual behavior, it always takes you by surprise: you press the power button, the screen lights up, the Mi or Redmi logo appears, and the boot process stops there. The device can vibrate, warm up or just glow for hours, but it never gets to the desktop. This phenomenon, known as bootloop, is one of the most common problems in the Chinese manufacturer's ecosystem.
The reasons for this behavior can range from a banal system failure to serious hardware malfunctions, often experienced by users after a failed firmware update, internal memory overflow or mechanical damage.
Before we take any drastic measures, it is important to understand the nature of the failure. If the Xiaomi phone is not turning on and hangs on the screensaver, this is a signal that the operating system cannot pass the initial check or download the necessary system files.
Diagnostics of the problem: software failure or hardware failure
The first step should always be a thorough diagnosis to separate software glitch from physical damage to components. If a device gets into βendless loadβ after a fall or contact with water, the probability of a hardware problem tends to maximize, in which cases software methods may be useless or even make the situation worse.
Notice the behavior of the charging indicator. If the LED does not light up or flashes red when you connect the cable, the problem may be in the power controller or the battery itself. However, if the phone responds to charging, but when you try to turn on it again goes into the restart cycle, it is a corrupt boot image or damage to the system partition.
β οΈ Warning: If the device body has visible signs of deformation and the screen is broken or cracked, self-activation can be dangerous.
Sometimes the problem is a sticky power button, and mechanical damage to the contact group causes the phone to receive a constant "Power" signal, which causes endless reboots. Check the tactile motion of the button: it should have a clear click and return to its original position.
Also worth remembering is the recent device-related activities: installing third-party launchers, obtaining Root rights, or modifying system files through Magisk often triggers instability, and if you've experimented with system settings, there's a greater than 90% chance of software error.
Basic methods of resuscitation without data loss
If the hardware is intact, we start with the least invasive methods, and the first and easiest way is to force reboot, which is different from a conventional shutdown, which is to drop the residual charge from the controllers and make the system re-initiate all the processes.
To do this, you need to press the power button and hold it for a long time, usually 10 to 20 seconds. The screen will go out, the device will vibrate, and the cycle will start again. If that doesn't work, try a button combination: press down Volume Down and Power simultaneously. Hold them until the logo appears or you go into Fastboot mode.
Another effective method is to "discharge to zero." Leave the phone with the screen on the screensaver until the battery runs out completely and the device shuts down itself. Then put it on charge (preferably with the original cable) and, not including, let it lie down for at least 30-40 minutes. Then try to turn it on in the standard way.
Often, the cause of the freeze is a crowded app cache or system debris. If the phone is still sometimes able to boot, immediately go to Settings β Memory and free up space. The critical threshold for stable Android is the availability of at least 10-15% of free memory from the total.

Use an original charger and quality cable. Cheap cables may not provide enough current to run the system in critical condition, creating the illusion of a discharged battery.
Using Recovery Mode to Reset Cache
If simple methods fail, you need to move on to deeper system tools, and Recovery Mode is a separate software environment that allows you to control the device independently of the main operating system, and that's where you can clear the cache or do a full reset.
To enter the Recovery menu on a device that is turned off (or forced to restart), you need to press the combination of Volume Up and Power. Hold the buttons until the logo appears, then release the power button, continuing to hold the volume. A multi-point menu should appear on the screen, controlled by the volume buttons, and the power button selects.
The first thing you should do is try to clear the cache. Find Wipe Cache or Wipe Cache Partition. This operation is safe for your personal data: it only deletes temporary system files that may have been corrupted. After cleaning, select Reboot and check your phone.
βοΈ The procedure in Recovery
It is important not to confuse cache cleaning with a full reset. Wipe Data or Factory Reset deletes all user information. Use it only if cleaning the cache has not helped and you are ready to lose contacts, photos and applications.
β οΈ Attention: In new versions MIUI HyperOS login to Recovery may require unlocking the screen or confirming through your Mi Account. If the phone is locked and not loading, this method may not be available without entering a password.
Fastboot Mode and Firmware via Mi Flash Tool
When software failures are too severe, Fastboot mode comes to the rescue, a low-level protocol that allows you to interact with the device bootloader directly from the computer, and it is through Fastboot that most often βcureβ phones hanging on the logo by completely flashing.
To get into the Fastboot, on the phone turned off, press Loud Down and Power. The screen will show an image of a hare repairing an android and the inscription will appear. FASTBOOT. Connect the device to the computer through USB-If the drivers are installed correctly, the Android Bootloader Interface will appear in Windows Device ManagerΒ».
To recover, you will need the Mi Flash Tool and a firmware file in.tgz (Fastboot ROM) format, not.zip (Recovery ROM). You can download the current firmware from official resources or trusted forums. Make sure that the firmware version matches your model (Chinese, global, European).
| Type of firmware | File extension | Method of installation | Data retention |
|---|---|---|---|
| Recovery ROM | .zip | Through the Update Menu or Recovery | Possibly (on update) |
| Fastboot ROM | .tgz | Through the Mi Flash Tool and Fastboot | No (complete removal) |
| Recovery (OTA) | .zip (automatically) | Through system settings | Yes. |
| EDL Mode | .mbn / .xml | Mi Flash (requires an account) | No (brick) |
The firmware process is as follows: unpack the firmware archive into the root of the disk (the path should not contain Cyrillic), run the Mi Flash Tool on behalf of the administrator, select the firmware file and press Flash.
