Why Xiaomi Phone Is Constantly Rebooting and How to Fix It

When your Xiaomi suddenly starts to reboot indefinitely, it can be taken by surprise at the most inopportune moment: the screen goes out, the logo appears, and the process is repeated over and over, making the device virtually unusable. This condition, often called "bootloop", causes panic among users, but in most cases the problem is solved without going to the service center.

The reasons for this behavior can range from a simple software failure to serious hardware problems, often a newly installed application, a crowded memory or a failed system update, and understanding the nature of the malfunction is the first step to successfully restoring the device.

In this guide, we will take a look at all possible scenarios and offer step-by-step instructions for eliminating cyclical reboots, learn how to distinguish between software errors and physical failures, and learn how to safely save data before performing radical actions.

The main reasons for the cyclical reboots Xiaomi

Before you start taking action, you need to analyze the background of the malfunction, and most often, a cyclical reboot is caused by a software conflict, it can be a system file that is corrupted during the recording process, or a third-party application that has embedded itself in the deep layers of the MIUI operating system.

Another common reason is a lack of space: when internal memory is critically filled, the system lacks the resources to function properly in the background, leading to an emergency shutdown and automatic restart, and the state of the battery should also be considered: if the voltage falls below the permissible minimum under load, the phone will go into reboot.

• 📱 Conflict of recently installed applications or system updates.
• 💾 Internal memory overflow or file system damage.
• 🔋 Battery wear or power controller malfunction.
• 🔌 Physical damage to the plume or control buttons.

⚠️ Note: If the phone starts to reboot immediately after falling or getting moisture, there is a high probability of physical damage to the board, in which case independent software methods may not help, and you will need a hardware specialist diagnosis.

Importantly, overheating of the processor can also trigger a reboot defense mechanism. If the device was running in high load mode (games, navigation) and suddenly went into a restart cycle, let it cool down before further manipulation.

Primary diagnosis and safe regimen

The first step in troubleshooting is to try to boot in Safe Mode, which allows you to start the operating system with third-party apps disabled, which helps identify the culprit, and if the phone is stable in Safe Mode, then it's one of the apps you installed.

To enter safe mode on most Xiaomi models, you need to press the shutdown button, and when the action menu appears, hold the "Stop" or "Stop" option for a long time. Some models require you to press the volume button immediately after the logo appears. If the device boots, check the task manager and remove suspicious programs.

If you can't enter safe mode or the problem persists, check the status of the control buttons. A sticky power or volume button can constantly send a signal to reboot. Carefully tap the body in the area of the buttons or try to slightly press them in different directions to free the mechanism.

Resetting settings via Recovery menu

When a standard boot is not possible, Recovery mode comes to the rescue, a special diagnostic interface built into the firmware that allows you to reset data, clean the cache and flash the device, which is entered into by a keyboard combination when the phone is turned off.

You usually need to press the power button and the volume button at the same time. Hold them until the Mi logo appears, then release the power, but keep the volume up. On the menu, the navigation is done with the volume buttons, and the choice is with the power button. You will need the Wipe Data item.

Select Wipe All Data and confirm the action. The process will take a few minutes. Once completed, select Reboot. If the problem was a software failure or damage to system files, the phone should start normally. However, remember that this method will completely destroy your personal data.

⚠️ Note: After resetting settings via Recovery on modern versions MIUI You may need to enter a password from a Mi Account that was previously associated with the device.

Fastboot and Mi Flash flash flash flashing

If the reset doesn't work, the last software method is complete flashing, and it uses Fastboot mode, which allows you to interact with the phone at a low level. You'll need a computer, USB-cable and utility Mi Flash Tool.

Download the current firmware for your model from the official website. Please note that for full recovery, it is recommended to use firmware such as Recovery or Fastboot marked "Clean All". Connect the phone turned off to the PC by holding the volume down button until the image of a hare in a hat or the inscription Fastboot appears.

Launch the Mi Flash Tool, select the folder with the unpacked firmware and click the "Flash" button. In the lower right corner, select the "Clean all" option to avoid conflicts with old files. The process can take from 5 to 15 minutes. Do not turn off the cable until the message of successful completion appears.

💡

Use the original. USB-cable USB 2.0 on the computer motherboard (back of the system unit). Ports on the front panel or hubs often give unstable power, which can interrupt the firmware.

This method is most effective at deep damage to the system partition, and it completely replaces the phone's software with the factory software, eliminating any software bugs, viruses, or consequences of failed superuser rights experiments.

Hardware problems and payment repairs

When all software methods are exhausted and the phone continues to reboot, it is a hardware malfunction. In Xiaomi smartphones, especially in the budget Redmi and Poco series, a common problem is the CPU or memory dump due to overheating or mechanical impact.

The power controller also often fails, and if the power distribution chip doesn't hold the voltage, the phone will go on an endless cycle of launch attempts, and you can only diagnose this at a service center using a multimeter and a power supply unit to measure the power consumption.

• 🔍 Tap. BGA-processor rations (requires rebolling).
• ⚡ Failure of the charge or power controller.
• 🔋 Battery bloating, putting pressure on the charge.
• 📉 Degradation of flash memory (eMMC/UFS), recording-defeat.

⚠️ Attention: Attempts to heat up the board with a hairdryer at home ("heating up the processor") give only a temporary effect and can finally finish the device.

Another hidden cause may be a short circuit in the circuits of the light or the vibrator, and if the current rushes to the maximum and goes into protection when connected to the power supply, then there is a circuit on the board, and it takes consumers to disassemble and disconnect in turn to find the faulty element.

Prevention and preservation of data

To avoid a recurrence of a cyclic reboot situation, it is important to monitor the state of the device: regularly clean the memory, do not allow storage to be filled by less than 1-2 GB. Avoid installing applications from unverified sources and questionable firmware assemblies.

Regular backups are your data loss insurance, use Mi Cloud, Google Photos, or local backups on your computer, and if you fail, you can quickly restore contacts, photos, and settings.

💡

Regular system updates and free space checks are the best prevention of software failures leading to reboots.

Also, keep your temperature up. Don't leave your phone in the sun, don't use heavy games while charging. Careful care will prolong your life and reduce your risk of critical system errors.
