When your Xiaomi reboots endlessly, it can throw any owner off balance. Five minutes ago, the device was working normally, and now the screen goes out, the Mi or Redmi logo lights up, and the process repeats itself over and over again. This phenomenon, known in the technical environment as bootloop or cyclical reboot, can be caused by both a software failure and a serious hardware malfunction.
Before you panic and bring your device to a service center, you need to make a good diagnosis. Often the problem lies in the conflict of a newly installed application or overcrowded memory, which can be eliminated on your own without deep knowledge of programming. However, ignoring symptoms early on sometimes leads to more complex consequences, including complete loss of data.
In this article, we will take a look at all the possible reasons why Xiaomi’s smartphone is going into rebound, and offer step-by-step instructions for restoring system health. You will learn how to use Recovery mode, what to do with volume buttons, and when to apply radical reset measures.
The main reasons for the cyclical reboot Xiaomi
Understanding the root of the problem is half the success of solving it. Most often, the endless reboot of Xiaomi Android devices is associated with software conflicts. This can be an incorrect application that tries to start the system process and causes a kernel crash.
Hardware factors can also be taken into account: If the phone falls or is exposed to moisture, the problem can be oxidation of the contacts of the display plume or damage to the memory chip. The switch is another common culprit: if it sticks or falls inside the case, the device receives a constant signal to restart.
⚠️ 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 when power is applied, which will permanently disable the motherboard.
System partition overflow is a classic situation for low-cost models with little internal memory: When the free space runs out completely, the MIUI or HyperOS operating system cannot create the temporary files and logs needed for stable operation, which leads to a crash restart.
Diagnostics through the Engineering Menu and Recovery
The first step to determine the type of malfunction is to log into a special recovery menu, which will allow you to understand whether the touchscreen and display are responding at all, or the problem is wearable. To enter, you need to completely turn off the device (if it does not turn off, press the power and volume button for 10-15 seconds before vibration), and then press the key combination.
Depending on the model and version of the shell, the combinations may vary, but the standard for Xiaomi is to hold the Volume Up Volume button along with the Power button.
☑️ Actions when entering Recovery
If the menu is loaded and you can navigate through the volume buttons, the display and the main power circuits are fine, and in this case, the problem is likely software, and if the phone continues to be retarded even when you try to log in to Recovery Mode, the probability of hardware failure increases by up to 80%.
Decoding of Recovery Menu Items
Methods of programmatic system recovery
If the diagnostics confirm that the device is responding to commands, you can try software treatments, the most gentle option is to clean the cache, which does not affect your personal photos, contacts and applications, but deletes temporary files that may have been corrupted.
From the Recovery menu, select Wipe Data, then Wipe Cache (the name may vary depending on the menu version, sometimes it's just Wipe). After you complete the procedure, select Reboot -> Reboot to System.
A more radical method is a factory reset, and note that this step will remove all data from the phone's internal memory, and only use it if backup is impossible or the data is worthless.
⚠️ Note: Before you run Wipe Data, make sure you remember the password from your Mi Account. After resetting, the phone will require authorization to an account that was previously synced for security purposes (protection against theft).
To reset the Wipe Data menu, select Wipe All Data and confirm the action. The process can take a few minutes. Once completed, the device will reboot as new.
💡
Wipe All Data eliminates 90% of software errors caused by system file failures or application conflicts, but requires a backup.
Problems with the on button and physical repairs
One of the most insidious reasons Xiaomi is endlessly rebooting is sticking the power button. Mechanical wear, dust or moisture causes the contact inside the button to close permanently, which the system perceives as the user holding the button and goes into a reboot cycle.
You can diagnose this problem visually and tactilely. Press the button: it should have a clear click and return to its original position. If the button is difficult to move, it fails or does not make a click, the problem is probably in the mechanism.
A temporary solution might be to tap the button area neatly or press it repeatedly to try to "curl" the mechanism, but this is only a temporary measure, requiring the device to be disassembled and the button plume or a separate microswitch replaced.
| Symptoms. | Probable cause | Method of decision |
|---|---|---|
| The phone turns off itself. | Battery wear and tear | Battery replacement |
| Camera launch reboot | Lack of memory / Mistake of software | Cache cleanup/Reset |
| Cycle after fall | Display plume departure | Reconnecting the plume |
| Reboot in your pocket | The button (Ghost touch) | Replacement of the switch |
Fastboot and Mi Flash flash flash flashing
When the soft methods don't work, you have the "heavy artillery" of flashing the device in Fastboot mode, which allows you to completely rewrite the memory partitions, eliminating any software errors. USB-cable and utility Mi Flash Tool.
First, you need to download the current firmware for your model from the official website or proven resources (for example, miui.com). It is important to choose the version of Recovery or Fastboot (with the extension.tgz) corresponding to the region of the device (Global, China, EEA).
1. Turn off the phone.
2.Clasp Volume Down + Power before the hare appears in the cap (Fastboot mode).
3. Connect the phone to the PC.
4. Launch the Mi Flash Tool and choose the path to the unpacked firmware.
5. Press Refresh, then Flash.When you do the firmware, the phone can reboot several times, which is normal, but you don't have to shut down the cable or shut down the software, and if it's successful, it will boot into the clean system.
💡
Use it. USB-port built directly into the computer motherboard (back of the system unit), rather than the front panel or USB-hub to avoid communication breaks when firmware.
What to do if nothing helps
There are times when neither reset nor flashing works. The phone continues to hang on the logo or go into the rebound immediately after booting. This is a sure sign of a hardware malfunction of the eMMC or UFS memory. The memory chip has a limited resource of rewrite cycles, and over time it can degrade.
The problem can also be in the power controller, where if it delivers unstable voltage to the processor, the system will go into protection and reboot, and it is almost impossible to fix such failures on its own without soldering equipment and circuits.
In such a situation, the only correct solution is to go to an authorized service center, and attempts to heat the memory with a hairdryer or “dilk” the board at home often lead to the final death of the device.
