When your Xiaomi suddenly starts to reboot endlessly, it can be taken by surprise at the most inopportune moment: the screen goes out, the Mi or Redmi logo appears, the device vibrates, and the cycle repeats over and over again. This phenomenon is technically called bootloop, and it indicates a critical failure in the software or, less commonly, in the hardware of the gadget.
You don't have to panic, because most of the time, the problem is solved by software without going to the service center, but it's important to be consistent and not miss the diagnostic steps so as not to make things worse or lose important data. In most cases, the culprit is a conflict application, a crowded memory or a system update failure.
Before you start a radical reset, you need to understand the nature of the error, and if you can turn the phone on for even a short time, it makes it much easier, otherwise you have to use button combinations to log into a special recovery menu.
Primary diagnosis and safe regimen
The first step when a cyclic reboot is detected is to try to boot into Safe Mode, which disables all third-party applications, allowing you to determine whether a newly installed program is causing the system to crash, and if the phone is stable in Safe Mode, then the problem is in the software.
To enter this mode on most Xiaomi models, you need to wait for the logo to appear during boot and press the volume down button. On some versions of the MIUI or HyperOS shell, this item is available through the off menu if the system has time to start. Hold the button until the desktop is fully loaded, where the corresponding inscription will be in the corner.
If you're logging into Safe Mode, check the list of newly installed applications immediately, delete anything you downloaded before the problem occurs, especially if it's from unverified sources or modified versions of popular services, and it's often the ones that cause conflicts in system libraries.
💡
If the volume button does not respond when booting, try connecting the phone to your computer via USB-cable at this point – on some models, this helps activate the boot mode selection menu.
Analysis of hardware buttons and mechanical damage
One of the most common but often ignored reasons for an endless reboot is sticking the on or volume button. If the Power button is physically clamped or closed due to moisture, the phone will perceive this as a constant signal to reboot.
Often the problem lies in the protective case. Too tight or deformed case can press on the keys, creating constant pressure. Remove the case and try several times to quickly press the switch on to "swift" the mechanism if it is stuck. It is also worth blowing the connectors and buttons with compressed air.
⚠️ Warning: If the phone has recently fallen or been in contact with water, do not try to charge it or connect it to a computer. moisture inside the case can cause a short circuit that will cause permanent damage to the motherboard.
Check the volume button as well, as many Xiaomi smartphones use a combination of volume and power to log into Recovery. If that button is closed, the phone can spontaneously try to enter and fly out of recovery mode, creating the illusion of rebooting.
Cache cleanup and reset via Recovery Mode
If simple methods don't work, you'll need access to the Recovery menu, which is a special partition that boots independently of the main operating system, where you can clear temporary files that may have corrupted and cause a reboot cycle.
To enter the Recovery menu, turn off your phone (if it turns on) or wait for the lock screen, then press the Volume Up and Power buttons at the same time. Hold them until the Mi logo appears, then release the power button, but keep the volume up until a menu with several items appears in English or Chinese.
☑️ Checklist before data reset
In the Recovery menu, you can navigate with volume buttons and you can choose with a power button. You need to find Wipe Data and choose Wipe Cache. This is safe for your personal files, photos and contacts, as it only deletes temporary system files. After cleaning, select Reboot.
If cleaning the cache doesn't work, you'll have to resort to a more radical method, which is a complete reset. In the same Wipe Data menu, select Wipe All Data. This action will remove absolutely everything from the device, returning it to factory status. Make sure you have a backup if possible.
Memory problems and storage overflow
Modern Xiaomi smartphones are sensitive to internal storage. If there is less than 500 MB of free memory, the system can work unstable, which is expressed in freezes and cyclic reboots. Android operating system needs space for paging file and temporary operations.
If you’ve been logged in for even a few minutes, immediately delete heavy files like videos, messenger cache like Telegram or WhatsApp, and unwanted apps, freeing up even 1-2 GB of space can stabilize the processor and prevent crashes.
| Type of data | Impact on the system | Recommended action |
|---|---|---|
| Cash app. | High (may cause conflict) | Clean through the application settings |
| Media files (photo/video) | Average (seat occupation) | Move to PC or cloud |
| System error logs | Low (takes up space) | Remove through the cleaning menu |
| Offline maps | High (takes up a lot of space) | Remove unused regions |
It's also worth checking the status of the microSD card if it's installed. A damaged or incompatible card can cause a system to crash when you try to read the data from it. Take the card out and try to start the phone without it. If the cyclic reboot stops, the problem is solved by replacing the drive.
Why does a crowded memory cause a reboot?
Failures after firmware update and rollback version
Often, the problem occurs immediately after a MIUI or HyperOS system update. If a server connection is interrupted or file recording fails during the upgrade, the phone may go into an endless loop, in which case standard methods may not help, and you will need to flash it.
To solve the problem, you can try the rollback method, if it is available for your model, or install the current stable version of the firmware through your computer. This will require the Mi Flash Tool utility and the firmware file in.tgz format, which can be found on the official Xiaomi forum.
⚠️ Warning: Flashing through the Mi Flash Tool with Clear All will completely destroy all information on your phone. Use this method only if the data is already lost or stored in the cloud.
The process is this: download the firmware, unpack it, launch the Mi Flash Tool, connect the phone in Fastboot mode (pressing the power button and volume down), and select the firmware file. It is important to choose the clean all mode for clean installation, which will eliminate conflicts between old files and the new system.
Hardware malfunctions: battery and plumes
If software methods are powerless, consider hardware: an old or swollen battery may not produce the required current at peak load times (e.g., when the system is loading), causing a sharp drop in voltage and reboot, especially for devices older than 3 years.
It could also be a battery plume or a display that has gone out, and if the phone has been hit, the contact could be disrupted, and in some cases, it helps to gently press the back cover in the battery area during boot, but this is a temporary solution, and it requires disassembly and contact checks.
Another hidden problem is overheating of the processor. If the heat paste is dry or the radiator has gone, the phone can go into reboot as soon as the temperature reaches a critical point. Feel the case: if it is unnaturally hot even when it is off (when connected to the charge), this is a sign of hardware malfunction.
💡
If the phone only reboots when connected to a charger of a certain power, the problem may be in the power controller, which incorrectly regulates the charge current.
When you need to contact the service center
There are a number of symptoms in which self-repair is not only useless, but also dangerous. If the phone does not respond to buttons, does not vibrate or make sounds when connecting to a PC, the motherboard or memory chip may have failed.
Also, the reason for visiting specialists is a situation where the phone shows a logo, but the screen remains black or covered with artifacts (strips, ripples), this indicates problems with the display or video chip that cannot be fixed software.
If your device is less than a year old and has no trace of mechanical damage or moisture, any repairs should be done officially, and self-opening the case automatically voids the manufacturer's warranty obligations.
