Your Xiaomi smartphone suddenly started rebooting for no reason, getting stuck on the Mi logo or going into an endless reboot?This is one of the most common problems faced by owners of the brand's devices, from the budget Redmi to the flagship Mi 13 Ultra. The causes can range from software failures to hardware malfunctions, but in 80% of cases the problem can be solved on your own without resorting to a service center.
In this article, we'll look at all the possible scenarios: why Xiaomi is going into a cyclical reboot, how to distinguish software failure from hardware damage, and what steps to take first. We'll focus on models with an unlocked bootloader, as they are more likely to suffer from unstable firmware. If your phone doesn't turn on at all, we also have a solution.
Before you panic, check whether the reboot is overheated (like after playing games or charging) or a battery that is discharged. Sometimes the problem is solved by simply cleaning the cache or changing the charger. But if the smartphone is stuck on the logo and does not respond to buttons, read on.
1. Reasons for constant reboot loop on Xiaomi
Bootloops or spontaneous reboots rarely happen for nothing, and here are the main reasons, ranked by frequency:
- 🔄 Firmware failure: Failed update MIUI, interrupted custom firmware installation (e.g. LineageOS), or Magisk module conflict.
- 📱 Damaged cache: System partition /cache dalvik-cache is filled with erroneous data.
- 🔋 Battery problems: Bloating, deep discharge (below 3%) or a faulty power controller.
- 🔥 CPU overheating: Common on the Redmi Note 10 Pro or POCO X3 Pro under intense load.
- 🛠️ Hardware malfunctions: Detached battery plume, oxidation of board contacts, damage to eMMC-drive.
- 🔓 Unlocked bootloader: Incorrectly installed TWRP orthose.
The most dangerous scenario is hardware failure, but it can be diagnosed by indirect signs. For example, if the phone vibrates when connecting to a charge but does not turn on, or the screen flashes but the image does not appear, this is a signal of problems with the hardware. Otherwise, start with software methods.

2.The first steps: what to do if Xiaomi is stuck on the logo
If the smartphone is stuck on the Mi/Redmi/POCO logo and does not load further, follow the following steps in order:
- Forced Reboot: Press the Power + Volume button for 10-15 seconds. Some models (e.g. Mi 11) use the Power + Volume combination.
- Charging check: Connect the original charger and wait 10-15 minutes. Sometimes the battery is discharged to a level at which the system cannot boot.
- Recovery Mode: Go to Recovery Mode (Power buttons) + Volume up) and select Reboot to System. If this is not available, proceed to reset.
If you force the phone to reboot the loop, it's a deeper problem.
- 📵 Turn it off. SIM-Memory card and card – they can conflict with the system.
- 🔌 Try another charger (preferably original).
- 🌡️ Refrigerate your phone if it overheats (put it on a cold surface for 10 minutes).

⚠️ Warning: If the phone vibrates when turned on, but the screen remains black, do not try to turn it on repeatedly - this can aggravate the problem with the eMMC drive.
3.Cache and data reset via Recovery Mode
If the phone turns on but goes into an endless reboot, the first thing you do is clear the cache. This won't delete your data, but it can fix the problem:
- Enter Recovery Mode (Power + Volume buttons).
- Select a language (if available) and go to Wipe & Reset (or Wipe Data).
- Select Wipe Cache and confirm the action.
- After cleaning the cache, restart the device (Reboot to System).
If the cache reset didn’t help, try hard reset, but note that it will delete all the data:
- In Recovery Mode, select Wipe Data → Wipe All Data.
- Confirm the action (it may be necessary to enter a password from the Mi-account).
- After reset, select Reboot to System.
Some models (such as the Redmi Note 9 Pro) will require re-assignment to the Mi Account after reset, and if you don’t remember the password, restore it in advance at account.xiaomi.com.

4. Flashing through Fastboot (if the reset didn't help)
If Xiaomi still goes into the reboot loop after reset, you have to reflash it through the Fastboot, which is suitable for all models, including the POCO F3, Mi 10T and Redmi K40.
- 💻 A computer with installed Xiaomi drivers and ADB/Fastboot.
- 🔗 Official firmware for your model (download from the official website).
- 🔌 Original. USB-cable (better from the set).
Instructions:
- Unpack the firmware in the folder from fastboot.exe.
- Turn your phone into Fastboot mode (Power + Volume Down buttons).
- Connect to your PC and execute the command: fastboot flash all (or fastboot flash all -w for full cleanup).
- Wait for the finish (10-15 minutes) and restart the phone.
If the process is interrupted with a FAILED error (remote: 'Flashing is not allowed'), then you have a blocked bootloader.
- 🔓 Unlock bootloader through the official Xiaomi tool (requires binding to Mi Account).
- 🔄 Repeat the firmware after unlocking.
⚠️ Note: Fastboot flashing erases all data, including photos and apps. If your phone had important files, try extracting them first. ADB (If the device is at least somehow responsive to the connection to the PC).
5. Diagnostics of hardware malfunctions
If all software methods have been tried, but Xiaomi is still restarting or not turning on, check the hardware.
| Symptoms. | Possible cause | Decision |
|---|---|---|
| The phone vibrates, but the screen is black. | Display plume has broken off or illumination is faulty | Disassembly and inspection of plumes |
| Rebooting when connected to charging | Faulty power controller or battery | Battery replacement or payment diagnosis |
| Accidental reboots under load | Processor overheating or memory problems | Cleaning from dust, replacing thermopaste |
| Hanging on the logo after falling | Damage to eMMC drive or soldered contacts | Diagnostics at the service center |
For self-diagnosis:
- 🔋 Check the battery: if it is swelling, replace it immediately (risk of fire!).
- 🔍 Check the charging connector: oxidation or pollution can cause power failures.
- 🌡️ Use the app. AIDA64 (If the phone is switched on in any way, check the temperature of the processor.
If you're not sure about your skills, you should contact the service, for example, replacing an eMMC drive requires soldering equipment and experience.
💡
Before visiting the service center, back up your IMEI (if your phone has ever turned on) and type in ##4636## and write down the phone information menu.
6.How to prevent repeated failures
To avoid reboot loop in the future, follow these guidelines:
- 🔄 Update. MIUI Only through official channels (settings) → Updating the system).
- 🛡️ Do not install custom firmware without unlocking the bootloader.
- 🔋 Use original chargers (cheap analogues can damage the power controller).
- 🧹 Clean the cache regularly in the settings (Memory) → Cleanup).
- 🔥 Avoid overheating: Do not play heavy games when charging, do not leave your phone in the sun.
If you like to experiment with the scalp:
- 🔓 Always unlock bootloader in the official way (via Mi Unlock Tool).
- 📥 Download firmware only from verified sources (Xiaomi Firmware Updater).
- 🔄 Do NANDroid backup before installing custom cores or Magisk modules.
💡
The most common reason for reboot loop after firmware is an incompatible version of MIUI or a corrupted firmware file. Always check the phone model and Android version before installing.
