The situation when your favorite smartphone Xiaomi stops responding to clicks, and the screen endlessly flashes the Mi logo, familiar to many users. This state, often called “bootloop” or cyclic reboot, can occur suddenly after a system update, installing a questionable application or even a device drop.
The first thing you need to understand is the nature of the failure: software is a glitch of the MIUI or HyperOS operating system, or there is physical damage to components. If the phone has recently fallen or contacted with water, the chances of self-recovery are reduced, but it is still worth trying to revive the gadget. In this article, we will analyze step-by-step algorithms of actions, from simple manipulation of buttons to complex flashing.
It is important to note right away that some recovery methods can result in complete deletion of data from the device’s internal memory. So if you have the option to back up through the cloud or computer before action begins, be sure to use it.
Primary diagnosis and forced reset
The easiest and safest way to try to get out of the boot cycle is to perform a forced Hard Reset button, which simulates battery extraction (if it were removable) and resets static voltage from the power controller. Press the power button and hold it for 10-15 seconds. If the screen goes out and the phone vibrates, release the button and wait for the standard boot.
Some Xiaomi and Redmi models require a combination of buttons. Try to press the Volume Up and Power key at the same time. Hold them until the vibration or logo appears. If the screen goes out, but the logo appears again and the cycle repeats, then the problem lies deeper in the software or file system.
⚠️ Warning: If the phone gets too hot in the camera or processor area during the reboot process, stop turning on immediately. Prolonged heating in the off state may indicate a short circuit on the board, and further inclusions may finish off the battery or power controller.
Sometimes the "discharge" method helps. Leave the phone with the logo burning until the battery is completely exhausted until the screen is completely turned off. Then plug the original charger and let it lie down on for at least 30 to 40 minutes. Then try turning on the device in the usual way. This method often helps if the failure is caused by a power surge or an error in power management.
Entering Recovery Mode and Cleaning Cache
If a simple reboot didn't work, you need to move on to more serious measures. Recovery Mode is a diagnostic environment built into the firmware that allows you to control the system bypassing the main bootloader. To get there, turn off the phone (if it's on, press the power and volume buttons before turning off) and immediately press the Volume Up + Power combination.
When the Recovery menu appears (usually a black screen with text and orange/blue buttons), the volume buttons (up/down) are controlled and the power button confirms the choice. You need to find the Wipe Data item. However, before erasing all data, try to find the Wipe Cache option (if available in your version of Recovery).Cache cleaning does not affect personal files, photos and contacts, but can eliminate errors in temporary files that interfere with downloading.
If you don't have a cache-only cleaning option, you'll run the risk of deleting all data. Select Wipe All Data or Wipe Data -> Wipe All Data -> Confirm. The system will ask for confirmation, often requiring you to select Confirm again. After the process is completed, which will take a few seconds, select Reboot -> Reboot to System.
☑️ Checklist before data reset
The reset process is irreversible. Once turned on, the phone will be like new, without your apps or settings. However, if the cause of the freeze was damage to system files or a conflict of updates, this method should help. If after the reset, the phone is stuck on the Mi logo again, the problem most likely requires firmware or repair.
Diagnostics through Fastboot mode
Fastboot (or Bootloader) is a low-level interface for connecting your smartphone to your computer. If the phone successfully enters this mode, it's a good sign that the processor, memory and screen are all working, and the problem is that the partition with the operating system is damaged. To log into Fastboot, press both the Volume Down button and Power on the phone turned off.
The screen should have a hare in an orange cap fixing an android and a FASTBOOT sign on it. If the phone enters and holds it, connect the device to a PC. The computer must identify a new device (often like the Android Bootloader Interface). If the phone doesn't respond to buttons, the screen is black, but it's charging, or the device is constantly rebooting and preventing you from entering either Recovery or Fastboot, these are signs of a more serious breakdown.
In Fastboot mode, you can try to run a cleanup command if you have ADB and Fastboot tools installed on your computer. Open the command line on your PC and type in:
fastboot erase cacheThis command will force the cache to clear through the computer, and you can also try the fastboot reboot command, which will reboot the device, and if the phone goes back into cycling after the fastboot reboot command, then the system or boot partition itself is damaged, and a complete firmware is required.

Complete flashing through the Mi Flash Tool
When the software reset doesn't work, the only software solution is a complete firmware reflash, USB-cable (preferably original and short) and the Mi Flash Tool. You will need to download the stock firmware for your particular model. Importantly, the firmware should be Fastboot type (has the extension.tgz), not Recovery (.zip).
Download firmware from an official website or proven resources (e.g. miui.com or xiaomirom.com). Unpack the archive to the root of the C disk so that the path is short, such as: C:\rom\. Remove and run the Mi Flash Tool on behalf of the administrator. Connect your phone in Fastboot mode to your PC.
In the program, click Refresh. If the drivers are installed correctly, a device with the code will appear in the list. Choose the path to the folder with the unpacked firmware. In the lower right corner, select Clean all mode. Press Flash and wait for the process to be completed. Green "success" signifies success.
| Parameter | Description | Recommendation |
|---|---|---|
| Type of firmware | Fastboot (.tgz) | Definitely for Mi Flash |
| Cleaning regime | Clean all | Deletes all data, solves 90% of problems |
| Battery charge | At least 50% | To avoid shutting down in the process |
| USB port port | USB 2.0 / 3.0 | Use ports at the back of the system unit |
💡
Use it. USB-Cheap charging cables often don't have the necessary contacts to transmit data, leading to a connection error in the Mi Flash.
The firmware process can take anywhere from 100 to 300 seconds. Don't turn off the cable or touch the phone at this time. Once completed, the phone will automatically restart. The first download can take up to 5-10 minutes -- that's OK, there's an app optimization going on.
Hardware problems: memory dump and plumes
If none of the software methods worked, or the phone doesn’t respond to the connection to the computer at all (the USB connection does not sound), there is a hardware malfunction. One of the most common problems of Xiaomi smartphones in recent years is a memory dump (eMMC or UFS). Due to overheating or production defects, the memory ball is soldered off the motherboard, which leads to an endless cycle on the logo.
Another common cause is damage to the display plume or the display module itself after a fall. Even if the screen glows and shows the logo, the lack of response to touch (including in Recovery) can indicate a problem with the touchscreen or its connector. It is also worth checking the on button: if it is stuck inside the case, the phone will constantly try to turn on or reboot.
⚠️ Attention: Attempts to warm up the board with a hairdryer or to compress the case in the area of the processor ("twisting method") at home often lead to final breakdown. BGA-You can damage other components.
To diagnose hardware at home, you can gently (without fanaticism) press the back cover at the top of the phone (where the processor is) or slightly bend the case. If the logo disappears, the Recovery menu appears or the phone begins to react - this is almost guaranteed "dump" of the chip, in which case only a service center with equipment for rebolling (rolling) memory will help.
Prevention and preservation of data
To minimize the risk of data loss and similar situations in the future, it is important to follow the rules of operation: Do not allow the phone to zero on a regular basis, use original chargers, also try not to interrupt the system update process and do not install applications from unknown sources that may contain malicious code that damages system files.
Make regular backups. Xiaomi smartphones have a built-in Mi Cloud that can sync contacts, messages, notes and even desktop layout. For photos and videos, you’d better use Google Photos or periodically copy files to your computer. Having a fresh copy of data will turn a terrible “brick” problem into a simply unpleasant but solvable moment.
💡
Timely backups in the cloud are the only guaranteed way to avoid losing important data in case of critical system failures.
If your phone is under warranty and you are not confident in your abilities, it is better not to start complex manipulations with the firmware, as this can be regarded as a violation of the warranty. Contact an authorized service center. However, if the warranty has already expired, the methods described above will help you save money on repairs and possibly bring the device back to life with your own hands.
