Xiaomi phone reboots itself without stopping: full guide

The situation of Xiaomi’s smartphone endlessly rebooting, forcing the owner to watch the Mi or Redmi logo, is one of the most stressful for the user.This phenomenon, known as bootloop, can occur suddenly after a system update, installing a questionable app or a physical hit, at which point the device becomes virtually useless, blocking access to contacts, photos and important data.

The main challenge is that the causes can be both software failures of the file system and serious hardware malfunctions of the motherboard. Understanding the nature of the reboot cycle is the first and most important step to successfully restore the device to health. In 80% of cases, the problem is solved by software reset or firmware without requiring replacement of expensive components.

The next step depends on whether the screen responds to touch and whether it manages to get into the recovery menu. If the Xiaomi phone itself reboots without stopping, you need to act in cool blood, consistently eliminating possible factors of failure, ranging from simple software conflicts to complex diagnostic procedures.

Diagnostics of the state: software failure or hardware failure

Before you start to act, you need to determine the extent of the disaster. If the device has time to show the lock screen or desktop before rebooting, this is a good sign that indicates a software conflict. Often the culprits are newly installed applications that are incompatible with the current version of MIUI or HyperOS.

However, if the Xiaomi phone itself reboots at the stage of the logo or black screen, the situation can be more serious. Hardware problems are often associated with overheating of the processor, battery bloating or the failure of the contacts of the plumes.

Notice how the device behaves when connected to the charger: If the phone vibrates but the screen remains black, or if it shows a charging icon and immediately goes out, this may indicate a deep battery discharge or a power supply failure.

Forced reset and safe mode

The first and safest method of combating freeze is forced reboot, which differs from a conventional shutdown in that it hardware interrupts all current processes and releases residual voltage in the control circuits. For most Xiaomi models, you need to press the power button and hold it for 10-15 seconds.

If the device reacts to prolonged pressing with a vibration and logo, there is a chance that the system simply “hangs” in the background. After turning on, try not to unlock the phone immediately, but let it lie down for 5-10 minutes. If the cyclic reboot stops, immediately back up important data, as the problem may recur.

If the phone has time to boot to the desktop, but after a minute goes back to the rebuke, you need to start Safe Mode. In this mode, the operating system blocks the launch of all third-party applications, allowing you to determine whether any of them is the cause of the failure.

• 🔘 Press the power button before the off menu appears on the screen.
• 🔘 Press and hold your finger on the “Switch Off” icon (or “Reboot” icon").
• 🔘 In the window that appears, confirm the transition to safe mode.
• 🔘 After downloading, remove the last installed applications.

If entering Safe Mode is not possible due to a constant reboot, this method will have to be skipped and moved to more radical measures through the Recovery menu.It is important not to panic and perform actions clearly, as rushing can lead to the accidental launch of unwanted functions.

💡

If Xiaomi’s phone itself reboots immediately after entering the unlock password, it’s likely the application that has access to the system or lock screen is to blame. Try uninstalling the last installed programs through your computer if you have access to the file system.

Enter Recovery Mode and Reset Settings

When conventional methods fail, the Recovery Recovery Menu comes to the rescue, a separate mini-mode written into a secure memory area that works independently of the main operating system, and that’s where the key to solving the problem lies if Xiaomi’s phone restarts itself without stopping.

To enter this mode, you need to turn off the device completely (if possible) or wait for the screen to go out during the cycle. Then you need to simultaneously press the Volume Up and Power buttons. Hold them until the Mi logo appears, after which the power button can be released, continuing to hold the volume key.

⚠️ Attention: In the Recovery menu, the touch screen may not work. Navigation is done with volume buttons (up/down), and the choice of item is confirmed by the power button.

Once you're on the menu, you'll see a list of options, often in English or Chinese, and we're interested in Wipe Data. Before you do this, it's important to understand that it will completely destroy all user data: photos, contacts, messages and applications. Internal memory will be formatted.

The reset process is as follows: select Wipe Data, then Wipe All Data. The system will ask for confirmation of the action, often requiring you to choose Confirm or OK. After completing the process, which can take a few minutes, you need to select Back to Main Menu and then Reboot -> Reboot to System.

Working with Fastboot and flashing the device

If a Recovery reset didn’t work and Xiaomi’s phone restarts itself without stopping, the operating system’s system files may have been damaged, requiring a complete firmware reflash, using Fastboot mode, which allows you to interact with the device at a low level via a computer.

To enter Fastboot mode, you need to turn off your phone and press the Volume Down and Power buttons simultaneously. A hare in an orange cap fixing an android should appear on the screen, and the inscription FASTBOOT. If the device enters this mode and does not spontaneously exit it, this is a good sign of the serviceability of the hardware.

For firmware, you will need a Windows PC, installed Qualcomm or MediaTek drivers (depending on the processor), as well as the Mi Flash Tool. The official firmware for your model must be downloaded from the site miui.com or proven resources. It is important to choose the version that was installed earlier or a newer version.

The process of firmware through the Mi Flash Tool:




1 Unpack the firmware archive in the root of the C disk (the path should not contain Cyrillic alphabets).




2. Run the Mi Flash Tool on behalf of the administrator.




3. Connect the phone in Fastboot mode to the PC.




4. Press the Refresh button and select the device.




5. Select Clean All mode and press Flash.

There are two types of firmware: Recovery (update over data) and Fastboot (complete cleanup). In the case of a cyclic reboot, it is recommended to use only the Fastboot method with full cleaning, as it ensures that all system partitions are replaced with serviceable copies.

Hardware causes and diagnosis of "power button"

One of the most common reasons why Xiaomi's phone reboots itself is because the power button sticks or shorts, and mechanical wear and tear or moisture causes the contact inside the button to be permanently closed, which the system perceives as an endless reboot requirement.

The simple way to test this hypothesis is to tap your finger carefully, without undue effort, or push it slightly in different directions, and if the nature of the reboot changes or the phone is kept on at a certain position of the button, the problem is mechanical.

Other hardware reasons include:

• 🔋 Battery wear: The old battery can’t give the required current at the time of the processor’s peak load, causing voltage drops and recharges.
• 📱 The plume dump: when falls, the plume of the display or main board could move away, which causes unstable work.
• 💾 Memory degradation: failure of the eMMC flash memory chip or UFS, What happens after 3-4 years of active operation.

If you suspect a hardware problem, self-repair is only possible if you have soldering skills and diagnostic equipment, and most of the time, you need to replace the power button (the plume) or battery in the service center.

Table of error codes and indicators

For a more accurate diagnosis, it’s helpful to know what the various indicators and messages that can flash on the screen or be given out by the computer when connected mean.

However, if the Xiaomi phone itself reboots without stopping and none of the software methods helps, and in Fastboot mode the device behaves unstable (itself disconnects from the PC), this is almost guaranteed to indicate a hardware defect.

💡

The critical point is the phone's ability to hold Fastboot mode, and if it's stable and doesn't warm up, the chances of software rescue are close to 100 percent.

Prevention and detention

To avoid a repeat of the situation when the Xiaomi phone itself reboots, you should adhere to several rules of operation: regularly update the software through official channels, avoid interrupting the download process, do not install applications from unverified sources, as they may contain malicious code that conflicts with the system.

It is also important to monitor the battery status and prevent the device from completely discharging on a regular basis. Using original or certified chargers prevents voltage surges that can damage the power controller. Periodic cleaning of memory from excess debris also prolongs the life of the file system.

⚠️ Note: If after all the manipulations, including flashing, the problem persists, further attempts to turn on may aggravate the situation.

In conclusion, fighting cyclical reboot is a process of exclusion, from simple actions like safe mode to complete flashing, you cover the entire range of software solutions, and once you see that they are ineffective, you should consider expensive hardware repair options.

💡

When buying used Xiaomi, be sure to check the device for cyclical reboots in stress tests. Run a heavy game or benchmark for 15-20 minutes - if the phone restarts under load, you should abandon the purchase.
