Xiaomi phone is constantly rebooting: how to fix

When your Xiaomi suddenly turns off and immediately turns on again, causing the screen to flash the MI or Redmi logo, it can panic any owner. This phenomenon, known as a “boot loop” or cyclic reboot, means that the operating system can not complete the boot process and correctly start the interface. Most often the cause lies in a software conflict, but you can not exclude hardware malfunctions, such as sticking buttons or bloating the battery.

Before you bring your device to the service center, you should try to fix the failure yourself using proven diagnostic methods. MIUI Android shell and HyperOS have built-in recovery tools that can be accessed even when the system is broken. In this article, we will discuss all possible scenarios, from simple software errors to complex cases that require flashing.

It is important to understand that recovery actions can vary depending on the model of your smartphone, whether it is a budget Redmi Note or flagship Xiaomi 13. Some methods require data storage, while others involve a complete reset. If the phone heats up in the area of the camera or battery during the reboot cycle, immediately stop trying to turn on and disconnect the charger, as this may indicate a short circuit.

Diagnostics of the problem: software failure or hardware

The first step is to determine the nature of the malfunction. If a Xiaomi phone is constantly restarting but has time to show the logo or download menu, most likely, the integrity of the motherboard is not violated. In 80% of cases, the culprit is a failed system update, a crowded memory or a conflicting application. However, if the device vibrates but the screen remains black, or the speaker cracks, the problem may be physical.

Notice how the device behaves when it connects to the charger. If the cycle is interrupted and the phone is charged when it is off, that's a good sign that it's a software problem or a critically low battery charge. If the phone goes into reboot even when the cable is connected, it's possible that the battery isn't keeping the voltage under the CPU load.

⚠️ Warning: If you have recently dropped your phone or been in the rain, cyclic reboot may be due to oxidation of contacts or the departure of the display plume.

For a precise diagnosis, try to run the device in a special mode. Press the volume down and the power button at the same time. If the phone vibrates and shows the Fastboot logo with a rabbit fixing an android, the basic components of the board are working, and this allows us to focus on software treatment of the system.

Forced reboot and check of buttons

The most common, but often ignored, method is to check mechanical buttons. If the power button is stuck or closed, the phone will perceive this as a permanent hold and reboot. Carefully inspect the case for dents, especially if you use a tight case that can press the key.

Try hard reset with a keyboard. Press the power button and hold it for about 10-15 seconds. Some Xiaomi and POCO models require simultaneous power and volume (top or bottom) buttons to be pressed, which breaks the battery power circuit in software and causes the controller to restart all processes from scratch.

• 🔌 Disable the charger and any connected cables before starting the procedure.
• 🔘 Press and hold the power button during 15-20 seconds before the logo appears.
• 📱 If the phone vibrates but doesn’t turn on, try the Volume Up combination" +"Nutrition".
• 🧼 Carefully clean the button area with a soft brush to remove dust or pile.

If the phone is still on after a long delay, immediately back up the data. The stability of the operation after such a reset can be temporary. Often the cause of sticking is the ingress of sweet liquid or condensate, which requires professional cleaning in an ultrasonic bath.

💡

Remove the protective case during the diagnosis. Cheap silicone cases deform over time and can constantly press the lock button, causing chaotic reboots.

Downloading in Safe Mode (Safe Mode)

If the phone turns on but goes back to the rebuke after a minute, the problem may be in a newly installed app. Safe mode allows you to download Android only with system services, disabling all third-party software. This is the perfect way to check if a virus or buggy program is the culprit.

To enter this mode on most Xiaomi models, you need to wait for the MI logo to appear after turning on, and then quickly press the volume button and hold it until the desktop is fully loaded. In the lower left corner of the screen, the inscription "Safe Mode" should appear. If in this mode the phone is stable and does not restart, then the hardware is working.

While in Safe Mode, analyze the list of installed applications. Delete any programs that were downloaded shortly before the problem occurred. Pay special attention to memory cleanup applications, antiviruses and system modifiers, as they have deep access to the MIUI kernel.

⚠️ Warning: In Safe Mode, some phone functions may not work properly and the internet may be disabled.

Once you remove the suspicious software, do the usual restart, if the cycle stops, the problem is solved, and if the phone continues to restart even in safe mode, the list of potential causes narrows down to system files or hardware.

Resetting settings via Recovery Mode

When a full-time boot is not possible, Recovery mode comes to the rescue, a separate mini-partition on the phone's drive that allows you to control the system bypassing the main interface, and enters by pressing the power button and the volume button at the same time.

In the Recovery menu, the navigation is done with volume buttons, and the choice is confirmed by the power button. You need to find the Wipe Data item. In newer versions of MIUI and HyperOS, this item is often hidden inside the submenu or requires you to enter a special code displayed on the screen to confirm actions.

There are two types of discharge:

• 🗑️ Wipe All Data: Completely delete all user data, return to factory state.
• 🔄 Reboot: Just reboot without changes (try this first).
• 🔒 Connect with MIAssistant: Mode for connecting to PC and firmware through cable.
• 🛡️ Safe Mode: Try downloading in Safe Mode (if available in your version of Recovery).

Selecting Wipe All Data will completely delete photos, contacts and applications. However, if the cause of the cyclic reboot was damaged system file or settings conflict, this action is guaranteed to fix the software part.

Flashing the device through Fastboot

If the data reset didn't work, it means the operating system itself is damaged, and then you need a complete flashing, USB-cable (preferably original) and Mi Flash Tool. Fastboot firmware is the most radical and effective recovery method.

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 Fastboot (usually has the extension.tgz), not Recovery (.zip). Then, the archive must be unpacked into the root of the C disk so that the path to the folder is short, for example: C:\xiaomi_rom\.

We follow the instructions:

1. Turn off your phone and enter Fastboot mode (Loudness down + Power).
2. Connect your phone to your computer with a cable.
3. Run the Mi Flash Tool on behalf of the administrator.
4. Press the Refresh button so that the program sees the device.
5. Choose the path to the unpacked firmware and press Flash (Clean All mode).

The firmware process takes 200 to 600 seconds, and you can't turn off the cable at that time, and if the process is interrupted, the phone can turn into a brick, requiring an authorized Mi Account to unlock, and once it's successfully completed, the phone automatically reboots to the clean system.

💡

Use of the original USB-cable USB 2.0 (black) significantly improves firmware success, as it provides stable voltage and data transfer.

Hardware reasons and when to go to the service

When all software methods are exhausted and the Xiaomi phone is still constantly rebooting, it remains a suspect of "hardware." A common cause is battery degradation. Lithium polymer batteries lose capacity over time and cannot produce the current required by the processor at the time of peak load at boot, which causes an instant reset.

Another common problem is the CPU or memory dump due to overheating or impact, and in such cases, the warm-up method (rebolling) can help, but this is a temporary measure that requires professional equipment. It is also worth checking the on button: if it "shorts", the phone will behave chaoticly.

Signs requiring the intervention of an engineer:

• 🔋 The phone is only turned on when the charger is connected.
• 🌡️ The back cover or the camera area warms up strongly in a few seconds.
• 💧 The device got moisture, even in small quantities.
• 📉 After the fall, artifacts appeared on the screen before turning off.

Self-repairing is risky, replacing the battery with current adhesive models requires care and special tools, and trying to replace the power button without a soldering hairdryer and experience can damage the plumes.
