The situation when the beloved Xiaomi suddenly stops responding to touch and refuses to turn off is familiar to many users: the screen burns, but nothing happens, or the device is completely immersed in the black screen of death.
Most often, the cause is a failure in the operating system MIUI or HyperOS, overflow of RAM or conflict of a newly installed application. Fortunately, engineers have provided several layers of protection and ways to resuscitate, from simple combinations of buttons to deep reset through the engineering menu.
In this tutorial, we will look at all possible scenarios, from a standard reboot to the difficult cases where the sensor completely failed, and learn how to safely bring the gadget back to life without losing data or, in extreme cases, how to perform a complete reset.
Standard and Forced Reset Methods
The first and obvious step to take if Xiaomi is going to “glut” is to try to perform a standard reboot, which usually requires a 10-15 second power button, and if the system is not locked completely, a menu will appear on the screen with a choice of actions: turn off, restart or call emergency services.
However, if the interface is dead and the sensor is not responding, you will need a hard reset method, which does not delete your data, it only forcibly breaks the power and starts the system again, clearing the RAM from the frozen processes.
- 🔘 Press the power button and hold it for 10-20 seconds before vibration.
- 🔄 If a short press didn’t help, try the combination: Power button + The volume button (Volume Down).
- ⏳ Hold both buttons at the same time for about 15 seconds until the Mi or Redmi logo appears on the display.
It is important to understand the difference between a conventional shutdown and a forced restart. In the first case, the system completes all processes correctly, in the second case, the power controller is reset hardware, and use the second method only when the first method is not available.
⚠️ Warning: If the smartphone freezes again in the reboot cycle after the logo appears, don’t try to turn it on indefinitely.This may indicate damage to system files or a battery problem.
What to do if the power button is broken or not working
The most difficult situation is when the power button is physically defective or has "gone" inside the case, in which case the classical methods become useless, and you have to resort to software crutches or specific actions with charging.
One effective way for fingerprint unlock models is to use a scanner. Try repeatedly putting your finger on the scanner (backward or embedded) when the charger is connected, sometimes triggering a system response that allows you to enter the menu or unlock the device.
The Secret Method with a Computer
There's also a method that involves battery discharge: Leave the smartphone on until it sits completely and turns off itself. Then put it on charge. When turned on, many Xiaomi models automatically start without pressing a button, or allow you to quickly press the power button when the logo appears.
- 🔋 Wait for the device to completely discharge to 0% and turn off independently.
- ⚡ Connect the original charger and cable.
- 👆 When the screen or indicator lights up, try pressing the volume or power button quickly.
If the screen is black but charging (the indicator is on), try connecting the phone to the computer. Sometimes the system recognizes the USB connection and "wakes up" the screen, allowing you to perform the actions.
Using Recovery Mode to Reset Settings
If a simple reboot doesn’t help and the system boots to the logo but doesn’t go any further, you need to use Recovery Mode.This is a special diagnostic mode built into the firmware that allows you to control the system at a low level.
To enter this mode on the device turned off, press the power button and the Volume Up button at the same time. Hold them until the logo appears, then release the power button, while keeping the volume down, and you will see a menu where the navigation is done with the volume button and the selection is done with the power button.
☑️ Actions in Recovery Mode
The Recovery menu will feature two options: Wipe All Data (full reset with deletion of all files) and Wipe All Data (Keep User Data) (reset only settings, photos and contacts will remain), the second option is not available on all firmware versions and depends on the level of security of the account.
⚠️ Warning: Before performing any actions in Recovery Mode, make sure you remember the password from your Mi Account. Once you reset, the system will require authorization for anti-theft protection).
Using Recovery is a last resort before flashing. Even if a complete data reset doesn't help fix the freezes, the problem is likely to be hardware or partition damage to the bootloader.
Diagnostics via Fastboot and ADB
For advanced users who have Xiaomi stuck and do not respond to standard commands, the Fastboot mode remains: this is a low-level interface that allows you to flash the device and perform deep diagnostics, and enter it by pressing the power button and the volume button on the phone turned off.
If the phone has gone into Fastboot mode (the screen usually shows a bunny fixing an android, or the words Fastboot), you can connect it to your computer. Using the ADB utility (Android Debug Bridge), you can try to send a command to reboot, even if the buttons do not work.
adb rebootThis command, which is typed into the command line of the computer when the phone is connected, will force the device to restart. If the phone is in Fastboot mode, the command also works:
fastboot rebootHowever, for these commands to work, drivers must be pre-installed, and debugging mode is USB (USB Debugging is included in the developer settings. If the debugging has been turned off before it freezes, unfortunately, this method will not work without prior preparation.
- 💻 Install Xiaomi drivers and platform SDK PC-only.
- 🔌 Connect your phone in Fastboot mode to your computer.
- ⌨️ Enter the command fastboot reboot in the terminal.
Fastboot mode is also useful for partition integrity checks: If the phone doesn't leave this mode or the computer can't see it, it may be a memory controller or display plume that's damaged.
Table of keyboard combinations for different models
Different Xiaomi, Redmi and POCO models may have slight differences in button combinations for entering special modes. Below is a summary table that will help you choose the right sequence of actions for your device.
| Action. | Button combination | Condition of the telephone |
|---|---|---|
| Forced reset | Power (10-15 sec) | On (hang) |
| Entrance to Recovery | Power + Volume Up | Off. |
| Entrance to Fastboot | Power + Volume Down | Off. |
| Resetting settings (menu) | Power + Volume Up (Wipe Data) | Recovery Mode |
Note that on some newer models with side-finger scanners, the volume button can be combined with a sound swinger, and in such cases, it is important to press the top or bottom of the key, rather than the scanner itself.
💡
Knowing the exact button combination for your particular model is key to success. Don't be afraid to experiment with press timing, sometimes you need to hold the buttons a little longer than usual.
Causes of hanging and prevention of problems
Understanding why the smartphone freezes will help avoid a repeat of the situation in the future, most often the culprit is a crowded cache of applications or a lack of free memory in the /data partition. When the free space runs out, the system has no place to create temporary files, and it “rises”.
Another common cause is conflicting updates or installing applications from unverified sources. Malware or simply poorly optimized software can create endless process cycles, loading the processor up to 100%.
- 🗑️ Clean the cache regularly in the "Security" menu" →"Cleanup".
- 📉 Keep an eye on the free space, leaving a minimum 10-15% memory-wasting.
- 🔄 Update the system only through official notifications OTA.
Also worth mentioning is the effect of temperature: CPU overheating causes trottling (decreased performance) and can cause a software crash that looks like a freeze. If the phone is hot, let it cool down before you try to reboot.
⚠️ Warning: Do not place the charging phone on soft surfaces (sofa, blanket) This disrupts the heat sink and can lead not only to freeze, but also to the bloating of the battery.
Prevention also involves a periodic full reboot (once a week), which helps the system to reset accumulated errors and free up resources.
When is the time to bring your phone to service?
There are situations where software methods are powerless: If Xiaomi is stuck, the screen is on, but the image is not (or distorted by color stripes), and the buttons do not cause any reaction even after an hour of retention - these are signs of hardware malfunction.
A common problem is the failure of the display plume or power controller. If the phone warms up in a certain area when connecting to charging or makes extraneous sounds (creaming, squeaking), immediately disconnect it from the network. Continued operation can lead to fire.
It’s also worth checking if the phone gets bootloop after being reset to factory settings, suggesting that the problem lies in physical memory (eMMC or UFS) that may have run out of overwrite life.
Don't try to open the case yourself if you don't have experience.Modern Xiaomi smartphones are tightly glued together, and a sloppy opening often results in battery or plumes damage, which automatically removes the device from warranty.
