Xiaomi phone is constantly rebooting: causes and solutions of 2026

If you have a Xiaomi smartphone (be it a Redmi Note 12, POCO X5 The Xiaomi 14 is stuck in a cycle of endless reboots, which is not a sentence, and this problem arises from software failures, corrupted system files or hardware malfunctions, the main thing is not to panic or try to "reanimate" the device at random. In 80% of cases, the phone can be brought back to life without visiting the service center, if you act on a clear algorithm.

The first thing to do is to determine the cause of the reboot cycle, and it could be the consequence of a failed update. MIUI, We'll go through all the scenarios that we can think of, from simple flashing to hardware diagnostics, and important, not all methods are data-safe, so prepare for possible loss of information.

If the phone is responding to charging (vibrates, lights up), but it doesn't turn on normally, the chances of recovery are high. The worst thing is when the device is completely lifeless (black screen, no vibration), in which case it could be a failure of the power controller or battery, but there are solutions here, as discussed in the last section of the article.

Warning: Don’t connect your phone to your PC before reading the Fastboot section: Mistakes with drivers or utilities like the Mi Flash Tool can turn your smartphone into a brick.

1.The reasons for Xiaomi's endless reboot

A reboot cycle (or “bootloop”) rarely occurs out of the blue, usually preceded by specific events, and here are the most common reasons for Xiaomi smartphones:

• 🔄 Failed update MIUI. It is especially dangerous to interrupt the process of updating through the air" (OTA) Or through Recovery. 2026 This type of problem is most often recorded on the Redmi Note. 11/12 and POCO F4/F5.
• 📱 Application conflict: Viruses modified APK or system utilities (such as Magisk for root rights) can damage critical files /system.
• 🔋 Battery or power controller problems: If the phone reboots when charging is connected or when the charge level is below 15%, the hardware is most likely to be to blame.
• 🛠️ Incorrectly unlocking the bootloader. Users who tried to get root through Unlock Tool often encounter a device blink (completely inoperable.
• 💾 Damage to section EFS Or Modem. It leads to loss. IMEI and cyclical reboots, especially on Qualcomm Snapdragon models (e.g. Xiaomi) 13T).

Interesting fact: in the forums 4PDA XDA-Developers users note that smartphones are powered by MediaTek processors (Helio) G99, Dimensity 9000 is more likely to suffer from bootloop after firmware SP Flash Tool, while Qualcomm devices are dying from the incorrect use of Fastboot.

To diagnose the problem more accurately, pay attention to the behavior of the phone:

• 🔹 Logo on fire Mi/POCO/Redmi and go out → problem with the bootloader or kernel of the system.
• 🔹 The screen flashes, but the logo doesn't appear → faultyness.
• 🔹 The phone vibrates at a certain frequency (for example, 3 times in a row) → hardware failure (see section on "iron").

⚠️ Note: If the phone only reboots when connected to Wi-Fi or mobile network, the problem lies in the Modem module. Don't try to reset settings - this won't help).

2. Simple solutions (without data loss)

Before you resort to radical measures, try methods that don't require resetting or firmware. 30-40% In some cases, they retain all your data.

Method 1: Forced resetting

Sometimes the system freezes during the boot phase due to a temporary failure.

1. Press the power button on 15-20 seconds (before the screen is vibrating or turning off).
2. If it doesn’t help, then cut the food. + Volume increase by 10 seconds (this simulates battery extraction).
3. Wait. 1-2 Just try to turn the phone on again.

Method 2: Download to Safe Mode (Safe Mode)

If the cause is in a conflicting application, safe mode will help calculate it:

1. When you turn on your phone (when the Mi logo appears), press the volume button.
2. Hold it until the system is fully loaded, and at the bottom of the screen, you'll see the word Safe Mode.
3. Remove newly installed applications (especially those that required root or access to system files).

Method 3: Checking the battery

If the phone is rebooted at a charge level below 20-30%, The problem could be a worn-out battery or power controller:

• 🔌 Connect the original charger and leave on charging 1-2 half-hour.
• 🔋 If the phone is only on charge, replace the battery (cost for Redmi) ~1500-2500 ruble.).
• 🔥 If the case is very heated when charging - the power controller is defective (requires repair in the service).

Method 4: Resetting cache via Recovery

Cache and Dalvik-cache can contain corrupted files that cause freezes to be cleared:

1. Turn off your phone (if necessary).
2. Hold the power. + Volume increase before the Recovery menu (Mi logo with Android robot).
3. Select Wipe & Reset → Wipe Cache (control – volume buttons, confirmation – power button).
4. Reboot your phone (Reboot → System)

⚠️ Note: Do not confuse Wipe Cache with Wipe Data! The second option will delete all your data (photos, contacts, messages).

3. Radical Solutions: Reset to factory settings

If simple methods don't work, you'll have to resort to a hard reset, which will delete all the data from the internal memory, but bring the phone back to life. There are two ways to reset Xiaomi: through Recovery and through Fastboot.

Method 1: Reset via Recovery (for unlocked bootloader)

This method works if you do not have a bootloader blocked (usually on phones purchased officially in Russia / Europe):

1. Go to Recovery (food) + volume).
2. Choose Wipe & Reset → Wipe All Data (on some versions of Factory Reset).
3. Confirm the action and wait for the completion (5-10 minutes).
4. Reboot your phone (Reboot → System)

Method 2: Reset via Fastboot (for a locked bootloader)

If Recovery is not available or requires a password, use Fastboot:

1. Install the Mi Flash Tool and Xiaomi drivers on your PC.
2. Hold the power. + Reduce volume before the appearance of the screensaver Fastboot (robot with the inscription) FASTBOOT).
3. Connect your phone to your PC and type in the command line: fastboot -w This command will reset userdata (your data) and cache, but will not affect firmware.
4. Reboot your phone with the command: fastboot reboot

Once reset, the phone will turn on as new. You'll need to reconfigure it. MIUI, log into your Xiaomi account and restore data from your backup (if it was).

4. Flashing the phone: step-by-step instructions

If the reset didn't work, the last software method is the complete firmware reflash. Xiaomi has two official ways: through Recovery (for updates) and through Fastboot (for brick recovery), and we'll look at both, but first prepare:

• 🖥️ Install on PC: Mi Flash Tool (for Fastboot) ADB and Fastboot (from Android) SDK) Xiaomi Drivers (download automatically when you connect your phone)
• 📄 Download the right firmware for your model: Official firmware: MIUI Downloads Castom firmware (e.g. PixelExperience): XDA-Developers
• 🔋 The charge of the phone should be at least 50% (better than 100%).

Method 1: Firmware through Recovery (for a working phone)

This method is suitable if the phone is turned on, but "obsessive" on the logo:

1. Download the firmware in.zip format (for example, miui_BLOCKOTARedmiNote12Global_V14.0.3.0.TMWMIXM_...).
2. Rename the file to update.zip and place it in the root of the phone's internal memory (use a memory card if the phone isn't turning on).
3. Go to Recovery (food) + volume).
4. Select Install update.zip to System and confirm installation.
5. After you complete the process, select Reboot → System.

Method 2: Fastboot firmware (for “bricks”)

If your phone doesn’t respond to anything other than Fastboot, follow this instruction:

1. Unpack the downloaded firmware (there should be files with extensions.img,.mbn, etc.).
2. Connect your phone to your PC in Fastboot mode (power) + volume).
3. Launch the Mi Flash Tool, press Select and specify the folder with the firmware.
4. Select Clean All or Clean All and Lock (if you want to lock the bootloader back).
5. Press Flash and wait until it is completed (10-15 minutes).
6. After successful firmware, the phone will restart automatically.

⚠️ Warning: If the phone doesn't turn on for more than 20 minutes after running through the Fastboot (black screen, no vibration), don't panic! some Xiaomi models (e.g. Redmi Note 10 Pro) load up to 30 minutes for the first time.

If the answer contains a number (e.g. anti: 4), the firmware must be no older than that number.-->

5. Hardware malfunctions: when you need help from the service

If none of the software methods worked, the problem is probably the hardware. Here are the most common hardware reasons for endless reboots:

• 🔋 Faulty battery or power controller. Symptoms: The phone reboots at a charge level below 20%. It doesn't turn on without charging, but runs on cable. The body heats up heavily when charging.
• 💾 Damaged flash memory (eMMC/UFS). Symptoms: The phone hangs on the Mi logo with a black screen. Fastboot identifies the device, but the firmware ends in a critical partition missing. E:Unable to mount appears in Recovery. /data.
• 📱 Symptoms: The screen flashes, but the phone does not load. When you press the body (for example, in the area of the camera), the phone responds.
• 🔌 Short circuit on the motherboard. Symptoms: The phone warms even when it's off. Not detected by the PC in Fastboot or Recovery.

To diagnose hardware problems, you can use the test mode (if the phone is turned on at least somehow):

1. Enter the dialer code: ##4636##.
2. Choose Testing → Single Test.
3. Check out Battery, Touch Screen and Storage.

If you suspect a hardware malfunction but are not sure of the diagnosis, contact the service center.Average repair cost for Xiaomi in 2026:

• 🔋 Battery replacement: 1500-3,000 rubles.
• 💾 Interpling of flash memory: 3000-6000 rubles.
• 📱 Repair of the plume display: 2000-4000 rubles.
• 🔧 Diagnosis of the motherboard: 1000-1500 rubles.

⚠️ Warning: If your phone has fallen into water or been hit hard, don't try to flash it through the Fastboot! A short circuit on the board can cause a complete failure when connecting to a PC.

6. Frequent questions about hardware failures

Question: The phone only reboots when it's connected to the charger. What's the matter?

Answer: Probably the power controller or the battery itself is faulty. Try charging the phone from another power supply (preferably the original one). If the problem persists, you need to change the controller (in the service).

Question: After the fall, the phone started to reboot. What do we do?

Answer: Probably the battery or display plume has gone away. Try to gently press the back cover in the area of the camera — if the phone stops rebooting, the problem is contacts. You can put a piece of paper under the cover (but better take it to the service).

Question: The phone warms up and reboots even when it's off. Is it a virus?

Answer: No, it's a hardware problem -- most likely a short circuit on the motherboard. Viruses can't work on a phone that's turned off. Immediately disconnect the device from charging and call the service!

7. How to avoid bootloop in the future

To prevent your Xiaomi from getting into a reboot cycle again, follow these guidelines:

• 🔄 Update. MIUI If the update "hangs" longer than 30 minutes, wait for the battery to discharge (the phone will turn off itself and turn on normally).
• 📱 Do not install modified firmware without unlocking the bootloader. This leads to a blink in 90% of cases.
• 🔋 Watch the battery health if the phone turns off when it's on. 20-30% Replace the battery with the battery.
• 🛡️ Use official chargers. Cheap cables and power supplies can damage the controller.
• 🔧 Don't disassemble your phone yourself unless you're confident in your skills. Damage to the plume of the display or battery is a common cause of bootloop.

If you like experiments with firmware, be sure to:

1. Make a backup through TWRP Recovery or Mi PC Suite.
2. Check the anti-rollback version before you run it.
3. Use only firmware designed for your model and region (Global/China/EEA).

💡

The most common reason bootloop on Xiaomi – interrupted update MIUI. Always wait for the system to load after OTA-Update (even if the process seems to be "hungry").
