When your smartphone stops responding to any action, it can be taken by surprise at the most inopportune moment.The screen burns, but touches are not processed, and the volume and power buttons are ignored. For owners of budget but reliable devices of the Redmi series from Xiaomi, it is not uncommon, especially when memory overflows or malfunctions in the MIUI operating system.
There is no need to panic in this situation, because hardware failure is a defense mechanism of the system that can often be bypassed by software methods. Forced reboot through a combination of power and volume buttons is a standard feature laid down by engineers in case of critical interface errors. In most cases, the device simply forgets about its duties and requires a hard power reset to restore performance.
In this detailed guide, we’ll break down all the known ways to resuscitate Redmi 04.We’ll look at both standard reboot methods and deeper options for entering Recovery Recovery mode or debugging Fastboot. Understanding these processes will help you not only turn off your phone, but also save important data or eliminate the cause of the freeze in the future.
The method of forced reset (Hard Reset buttons)
The first and most secure way to try if the phone's screen doesn't respond to touch is to delay the power button for a long time. Unlike the usual short press that causes the shutdown menu, a long clamp triggers the power controller's hardware reset.
You need to find the power button, which on the Redmi 04 is usually located on the right side of the body. Press it and hold it for 10-15 seconds. Don't let go of the button even if the screen goes out. The system should vibrate and show the Mi or Redmi logo.
⚠️ Warning: If nothing happens after 15 seconds of retention, do not increase the pressure force. Excessive force can damage the button mechanism or damage the display matrix, which will turn the software problem into an expensive iron repair.
Sometimes standard retention doesn't work because of deep freeze of the System UI process. In that case, try a combination of power and volume buttons. Press the volume button and press and hold the power button without letting go. Hold both buttons for about 20 seconds. This method emulates battery extraction, which was standard for older phones.
💡
If the phone is in the case, be sure to remove it before trying to reboot. Some protective cases can block the full stroke of the buttons, which prevents the signal from reaching the motherboard.
Using Recovery Mode to Turn Off
If the software buttons don't work and the screen displays at least a partial image, you can try to get into the recovery menu. Recovery Mode is a separate partition in the phone's memory that loads before the main operating system starts, and this is controlled by physical volume buttons.
To enter this mode on Redmi 04, you need to turn off the phone (if it is still on) or wait for the battery to drain, and then do the following: Press both the Volume Up and the Power button. Hold them until the Mi logo appears, then release power, but keep the volume until the menu with a black background and colored lines appears.
In the Recovery menu, the touch screen usually doesn't work. Navigation is done with volume buttons (up/down), and the power button is the choice. You need to find Power Off or Reboot. If the system suggests you choose a language, use volume buttons to select English and confirm with the power button.
1. Make sure the battery charge is above 10%.
2. Press Volume Up + Nutrition.
3. Wait for the vibration and logo.
4. Let go of the food, keep the volume.
5. Select Power Off from the menu.-->
It's important to understand the difference between modes. If you're on the Fastboot menu, just press the power button for 10 seconds to turn off. Fastboot is designed for firmware, but it also allows you to perform a hard reboot of the device.
What to do if the touch screen is suspended
Often the phone is working, the system sounds are playing, but the touchscreen completely ignores the taps, in which case the shutdown by standard methods may not be possible if the buttons are also blocked by a software failure, there is a method to "wake up" the sensor or access control.
Try connecting the device to the computer through USB-Sometimes, connecting to a power source or PC causes interruption of current processes and a short-term reaction of the system. If the phone makes a connection sound, try to quickly press the screen in different zones. OTG-computer-mouse adapter.
If you can connect your mouse through OTG, you'll see a cursor on the screen, which will allow you to gently navigate the settings menu and perform a routine shutdown or reboot through the software interface, which is the only way to turn off your phone if the physical buttons fail completely, but the system works.
Once a week.
Only after the updates
Rarely, with a lack of memory
Never hung up.
Always, you need to change.-->
Another trick that sometimes helps with a hung sensor is to call the device from another phone, and when an incoming call comes in, the system prioritizes the processing of the call, and the touchscreen can become responsive for a couple of seconds, at which point you need to have time to reset the call or press the switch off button.
Why Redmi 04 is not responding
Understanding the cause of the freeze will help prevent problems in the future. The Redmi 04, released a few years ago, has limitations on RAM, and when RAM is overflowing with background processes, the system does not have time to process incoming commands, which leads to complete disregard of the interface.
A common cause is internal storage overflow: If the space is less than 500 MB, the Android operating system cannot create the temporary files and cache needed to work. This causes cyclical freezes that users often perceive as a breakdown.
Battery wear is also worth considering: When the battery is degraded, the voltage may drop below critical levels during peak loads (e.g. when a camera or heavy application is launched), at which point the processor resets the frequencies or the device freezes in an attempt to save data.
| Symptoms. | Probable cause | Decision |
|---|---|---|
| Black screen, no reaction. | Deep system freeze | Hard Reset (Nutrition + Loudness) |
| The screen is on, the touches are not working. | Touchscreen or UI failure | Connecting the mouse via OTG |
| Cyclical reboot | Damage to system files | Reset to factory settings |
| The phone is warming and hanging. | Processor overheating | Cooling and closing of background apps |

Program reset via ADB (for advanced)
If the buttons are physically correct, but the system blocks their processing, you can try to turn off the phone using your computer and the ADB debugging bridge. This method requires that the phone previously had the option "Debug over USB." If it is activated, you can control the device remotely.
To do this, you need to install Xiaomi drivers and the SDK Platform-tools platform on your computer. Connect your phone with a cable to your PC. Open the command line in the ADB tool folder and enter a command to check the connection.
adb devicesIf a device with a serial number appears on the list, it means that the connection is established. To turn off the phone, use the following command, which sends a signal to end work directly to the kernel of the system:
adb shell reboot -p⚠️ Attention: Reboot team -p Power off: Make sure you don’t lose unsaved data in open applications, as the process will be completed instantly without warning.
This method is the most software-friendly, because it doesn't abruptly interrupt processes, but rather tells the system to get the job done correctly, but if it's stuck at the kernel panic level, the ADB may not respond.
Prevention of hangings and care of the system
To keep your Redmi 04 running for a long time and not requiring constant reboots, you need to monitor the state of the software. Regularly clean the cache of applications, especially social networks and instant messengers, which tend to accumulate gigabytes of temporary files.
Do not install applications from unknown sources. APK-files can contain malicious code that mines cryptocurrency in the background, loading the processor and causing constant freezes.
💡
Regular reboot (every 3-4 days) clears the RAM of fragmented data and prevents 90% of random freezes of the Android system.
Also watch for MIUI system updates. Although support may be discontinued for older models, the latest stable versions of security patches often contain memory bug fixes. If the phone is slow, consider resetting to factory settings.
In conclusion, if none of the software methods worked and the phone continues to hang right after turning on, the problem may be hardware, the power controller or the display plume may have failed, in which case a diagnosis will be required at the service center.
