Xiaomi's phone is constantly rebooting: what to do

The situation where Xiaomi smartphone suddenly starts to reboot endlessly, forcing the owner to observe the endless logo of Mi or Redmi, is one of the most stressful for the user.This phenomenon, often called bootloop, can be caused by both a software failure after a failed update, and a critical lack of space in the system partition. Understanding the nature of the problem is the first step to saving data and restoring the device.

Before you bring your gadget to the service center, it's worth analyzing past events: Was there a questionable program installed? Did the phone fall into the water? The answers to these questions will help you choose the right algorithm for actions. In most cases, the cyclic rebuke can be eliminated yourself using built-in recovery tools without resorting to complex soldering or flashing through the computer.

It's important to stay cool and act consistently. Sharp movements like trying to disassemble the case without experience or connecting to untested power sources can make things worse. We'll look at proven methods to help bring an Android device back to life, from simple button manipulation to a complete reset.

The main causes of cyclical reset

The fundamental reasons why Xiaomi’s phone goes into an endless reboot are usually two: software and hardware, with the former being the MIUI or HyperOS operating system that can’t load system files correctly, often after an interrupted update or installing root-enabled applications.

Hardware problems can be associated with wear of the battery, which is not able to produce the necessary current at the time of start of the processor, or with damage to the plumes of the display and buttons.

• 🔋 Critical battery wear or battery bloating.
• 📲 Damage to system files after failed update.
• 🦠 Viral software or conflicting applications.
• 🌡️ Overheating of internal components of the device.

⚠️ Note: If the phone starts to reboot immediately after falling or getting moisture, the use of software recovery methods (reset, flashing) can be useless and even dangerous for electronics.

Special attention should be paid to the power button. If it is stuck or closed due to dirt, the device will perceive this as a constant signal to reboot. Easy tapping on the body or cleaning the area of the button sometimes helps to temporarily solve the problem.

Primary diagnosis and safe regimen

The first step in troubleshooting is to try to load your smartphone into Safe Mode, in which the operating system disables all third-party applications, downloading only system services, and if the phone is stable in Safe Mode, then the problem is definitely in one of the applications you install.

The algorithm may differ from one version of MIUI to another to enter this mode, and most often you need to press the turn off button, and when the turn off menu appears, (hold) the "Stop" or "Reset" option. Some models require you to press the volume down button as soon as the logo appears.

If you manage to get to the desktop in safe mode, immediately remove the newly installed programs. Launchers, antiviruses and applications for cleaning memory are of particular concern. After removing the problematic software, perform a normal restart.

• 🛡️ Disables all user applications.
• 🔍 Allows you to identify conflict software.
• 🚀 Accelerates the system during the diagnosis.

Using Recovery Mode for Resetting

If you can't load a standard load, the Recovery menu comes to the rescue, and it's a special low-level mode built into the phone's memory, and you can get into it by turning off the device (if it's turned on) and holding the key combination: usually Volume Up + Power, hold the buttons until the Mi logo appears, and then the power button can be released, while you keep the volume.

In the Recovery menu, you can navigate with volume buttons and choose with a power button (some models have a touchscreen). We are interested in the Wipe Data item. It is important to understand that this step will delete all your personal data (photos, contacts, messages), so it is worth going to it if other methods did not help or if the data is not important.

Select Wipe All Data and confirm the action. The process will take a few minutes. Once completed, the phone will prompt you to return to the main menu (Back to Main Menu) or reboot. If the problem was a software failure of the configuration files, the device should start normally.

⚠️ Note: After resetting your data via Recovery, the system may require you to enter the username and password from the Mi Account that was previously associated with the device. This is theft protection. If you do not remember the password, it will be extremely difficult to restore access.

Checking hardware buttons and power

Sometimes the reason is trivial and mechanical: the power button on Xiaomi and Redmi smartphones is under enormous strain; over time, it accumulates dust, pile or contact oxidizes; if the button sticks when pressed, the phone will endlessly try to turn on or reboot.

Try to press the power button carefully, without undue effort, several times quickly. Sometimes it helps to "curl" the mechanism. It is also worth removing the case - it can press the button, simulating a press. Visually inspect the charging connector: if there is debris, the phone may not charge and go into the receptacle due to lack of power.

The battery situation requires special attention. If the phone is 3-4 years old, its battery could degrade so much that it can not keep the voltage under the load of the processor. At the time of loading, the CPU consumes maximum current, the voltage drops, and the phone turns off, then tries to turn on again - the cycle repeats.

• 🔌 Check the originality of the charger.
• 🧹 Clear the connector. USB-C dusty.
• 📱 Remove the protective case to check the buttons.
• 🔋 Try charging your phone when it’s off.

Fastboot and Mi Flash Tool

When soft reset doesn't work, you have "heavy artillery" -- you have to flash the device through your computer, and you have to put it into Fastboot mode, which is usually done by pressing the Volume Down + Power button, and you'll see a picture of a hare repairing an android, or you'll see a FASTBOOT.

You will need a Windows PC with original USB-cable and the Mi Flash Tool (ROM) You need to download in advance from the official site, choosing the version of Fastboot (archive.tgz), not Recovery (.zip.

Run the Mi Flash Tool, select the folder with the unpacked firmware and press the Flash button. clean_all (complete cleaning, to ensure that errors are eliminated. 5-10 Do not turn off the cable until you have a success message.

💡

Before firmware, be sure to install the ADB and Fastboot drivers. Without them, the computer will not see the phone in bootloader mode, and the Mi Flash program will show an empty list of devices.

When a service center is needed

There are a number of symptoms that indicate that software methods are powerless: If the phone is warming in the processor area even when it is turned off when connecting to a charge, or if artifacts (bands, ripples) appear on the screen before rebooting, these are signs of hardware breakdown.

A common problem with Redmi's budget models is that the processor or memory dump is overheated or impacted, in which case only warming up (rebolling) in service or replacing the motherboard helps, and the service can replace the button plume if the diagnosis confirms that they are malfunctioning.

Don't try to open your phone yourself if it's warranty--you'll lose the right to free repairs. Even if the warranty is over, it's better to entrust complex motherboard repairs to professionals with a soldering hair dryer and microscope.

💡

If the problem with reboots persists after a complete flashing through Fastboot, the probability of hardware failure is 99%.
