Users of Xiaomi, Redmi and Poco smartphones often experience a situation where the device suddenly turns off and immediately turns on again, showing the brand logo. This phenomenon is called reboot or cyclic reboot. For the owner of the gadget, it is always stressful, because it is not clear whether the data is lost or whether the phone will work at all.
In most cases, this behavior is a protective mechanism of the MIUI or HyperOS shell, responding to a critical software error. However, sometimes the cause lies deeper, in hardware failures or damage to system files after a failed update. Understanding the nature of the process is the first step to successfully restore the device.
Next, we will discuss in detail why there is an endless download cycle, what actions are absolutely not allowed to be performed at this moment and how to correctly diagnose, you will learn to distinguish between a software failure and a serious breakdown, and also receive step-by-step instructions for returning the device to life without going to the service center.
Causes of cyclical discharge
The phenomenon of Xiaomi constantly rebooting can be triggered by a variety of factors, most often the culprit is an unsuccessful firmware update that is interrupted at the most inopportune moment, resulting in system files being corrupted and the operating system cannot properly complete the initialization process.
The second most common cause is third-party application conflicts, and if you recently installed a program from an unverified source or updated the system component manually, it could have implemented the code that causes kernel panic.
Hardware problems can also be ignored: CPU overheating, battery bloating, or short circuit in the power supply chain are often perceived by the controller as a critical error, in which cases software treatments may be useless and require the intervention of an engineer.
- 🔋 Battery discharge: insufficient charge to complete the loading process.
- 📱 Mechanical damage: the fall could have moved the plume of the display or motherboard.
- 💾 Overflowing memory: lack of free space blocks the work of system processes.
- 🦠 Viral software: malicious scripts disrupt the work of the bootloader.
⚠️ Warning: If the phone starts to warm up in the area of the camera or processor before the start of reboot cycles, immediately stop trying to turn on.This may indicate a thermal breakdown of the battery, which is dangerous for safety.
Diagnostics of loader status
Before we go into radical action, we need to understand the state of your device's bootloader. A bootloader is a small program that runs to the operating system and checks the integrity of its components. If the phone responds to the push of buttons, then the hardware is alive and the chances of salvation are high.
Try to pinch the key combination to enter Fastboot mode. Usually this is the volume button and the power button held simultaneously in the off state. If you see a bunny fixing an android on the screen or the Fastboot inscription, the hardware is intact, in this mode you can reflash the device or reset the settings.
What do the color of the indicator mean?
Also, check Recovery mode. To log in, press the volume and power button. If you see a menu with a selection of languages or Wipe Data and Reboot, the recovery section is intact. That's good news, because it allows you to reset without connecting to a computer.
| Regime. | Button combination | Appointment |
|---|---|---|
| Fastboot | Loudness - + Nutrition | Firmware, unlock. |
| Recovery | Volume + + Nutrition | Data reset, update |
| Safe Mode | Loudness - (when loaded) | Diagnostics of applications |
Forced reset methods
The easiest and safest way to try to exit the reboot cycle is to perform a forced reboot, which helps to reset static electricity and clear the RAM of temporary errors that could cause the freeze.
To perform the procedure, you need to press the power button and hold it for a long time, usually 10 to 20 seconds, the screen must go out, after which the Mi or Poco logo appears, and you need to release the button only after the logo appears.
☑️ Algorithm of actions when hanging
If conventional retention doesn't work, try combination methods. Some Xiaomi models have the power button and any volume key simultaneously pressed. It's important not to panic and give the device time to react, as the processor may be busy with background recovery tasks.
- 🔄 Long-term pressing: hold power for up to 30 seconds.
- 🔌 PC Connection: Sometimes Connecting Cable USB Starts the charging process and wakes up the system.
- ❄️ Cooling: If the phone is hot, let it cool before trying to turn on.
⚠️ Warning: Do not shake or tap the device to try to revive contacts, which can cause the memory chips to detach, making recovery impossible at home.
Resetting settings via Recovery Mode
If a software failure prevents the system from booting, the only way out is often a complete reset via the recovery menu, which will delete all user files, photos and apps, returning the phone to factory status, and is the only way to save the device if the user partition file system is damaged.
To enter the Recovery menu, turn off the phone (if it turns on, press the power before it turns off). Then press the volume button and press the power button without letting it go. Hold both buttons until the logo appears, then release the power, but keep the volume up until the menu appears.
In the menu, you can navigate with volume buttons (up-down), and the choice is confirmed by the power button. You need to find Wipe Data or Clear Data, then select Wipe All Data. Confirm the action by selecting Confirm. After the process, select Reboot.
💡
A full reset via Recovery removes all data, but eliminates 90% of the software errors that cause a cyclical reboot.
The formatting process can take a few minutes. Don't interrupt it or remove the battery if it's removable. Once rebooted, the phone will look like new, you'll need to set up your Google account and your Mi Account in the first place.
Recovery via Computer and Mi Flash
When built-in methods are powerless, a computer comes to the rescue. The official Mi Flash Tool allows you to reflash your device in Fastboot mode. This method requires the availability of ADB and Fastboot drivers, as well as downloaded stock firmware for your model.
Download the firmware from the official miui.com website or verified sources. It is important that the firmware version is no lower than the one that was before, otherwise Anti-rollback protection will work, which can permanently lock the device. Unpack the archive in the root of the C disk so that the path does not contain Cyrillic.
fastboot devicesConnect your phone in Fastboot mode to your computer. In the command line, type the command above. If the computer sees the device, you'll see the serial number. Run the Mi Flash Tool, select the path to the firmware and press the Flash button. Select the mode. clean_all cleaned.
💡
Use the original. USB-cable USB 2.0 on the motherboard (back of the system unit), as the ports of the front panel or hubs often give unstable power, which interrupts the firmware.
Prevention and safe use
To prevent the reboot problem from recurring in the future, you need to follow the rules of electronics operation. First of all, watch for free space in memory. If the internal storage is more than 90% full, the system begins to work unstable, which can lead to write errors and subsequent failures.
Update your applications and system regularly, but only through official channels. Do not install modified MIUI or custom cores unless you have a deep knowledge of Android development. Any interference with the system partition increases the risk of errors.
- 🛡️ Antivirus: Check your phone periodically for malware.
- 🔋 Charging: Use only certified power supplies and cables.
- 🌡️ Temperature: Avoid using your phone in direct sunlight.
