When the Xiaomi Redmi 9 smartphone stops responding to touch and refuses to execute commands, it can catch anyone by surprise: the screen burns, but the system does not respond, or the device is completely gone and does not want to turn on. At such moments, the standard settings menu becomes unavailable, and the only way out is a forced reboot.
Often referred to as hard reset or hard reset (although the latter more commonly refers to a complete data reset), this procedure is a safe method of restoring the system to health.It does not delete your personal files, photos or contacts, but only forcibly shuts down and restarts the MIUI operating system, clearing RAM from erroneous processes.
In this article, we will discuss in detail all the existing ways to resuscitate your gadget, you will learn how to correctly combine buttons, what to do if the screen is completely black, and how to use computer utilities in the most difficult cases. Holding the buttons for more than 30 seconds will not harm the device, since this is a regular function of the power controller.
Basic method of button reloading
The most common and effective way to make the Redmi 9 work again is to use a physical button combination, which mimics battery extraction, which was standard for older phones, but is now implemented by hardware and software, and you need to find the power button, which is on this model on the right side of the case.
Press the power button and hold it for a long time. It usually takes 10 to 20 seconds for the system to ignore the operating system's requests and send the signal directly to the power controller. At some point, the screen will go out and you will feel a slight vibration, which means that the process has started.
Don't let go of the button once the screen is out. Keep holding it until the Mi or Redmi logo appears. If you release the button too early, the device may simply go into sleep mode instead of fully restarting. Once the logo appears, you can release the button and wait for the desktop to load.
☑️ Algorithm of actions when hanging
Combination of volume and power buttons
If the standard long-term hold of the power button fails, or if the touch screen is completely paralyzed and does not even give you a chance to see the menu, you need to use an alternative combination. On Xiaomi smartphones, a bunch of volume and turn on buttons often work to enter special modes, which can also initiate restarts.
Try to hold the Volume Up and Power button together for about 10-15 seconds at the same time, a combination often used to enter Recovery mode, but on some firmware versions or under certain conditions, it can cause the device to restart immediately without any hanging processes.
Another option is a combination of Volume Down and Power, which often brings Fastboot mode, but the mere fact of entering this mode means that the phone's hardware is intact. From the Fastboot menu, you can choose the reboot option using volume buttons for navigation and power button for confirmation.
- 🔘 Hold the volume up. + Meals for attempting to enter Recovery.
- 🔘 Hold the Volume Down + Food for entering the Fastboot.
- 🔘 In the Recovery menu, use volume buttons to select Reboot item.
- 🔘 Confirm the choice of the power button.
⚠️ Warning: Be very careful when you're in the Recovery menu. Don't choose Wipe Data or Format Data if your goal is just to reboot.
Method of full discharge of the battery
In cases where the software glitches are so deep that the phone doesn't respond to any combination of buttons, and the screen either burns with a static image or flashes chaotically, there's only one physical method left: total discharge, which is a "grandfather" way that is guaranteed to work, because it deprives the device of its power source.
Leave the phone on until the battery runs out completely and the device shuts down on its own. On the Redmi 9 with its capacious battery, this can take anywhere from a few hours to a day, depending on the residual charge. Once the screen has gone out and the phone stops responding to the charger's connection (the charging indicator does not light up), you can start the next step.
Connect your smartphone to the charger. Without pressing the power button, let it lie on the charge for 10-15 minutes. Then try turning it on with the usual short press of the power button. Often after a full discharge and charging cycle, the power controller resets its errors, and the system boots normally.
Why does total discharge help?
Use of computer and ADB
For advanced users who previously had USB debugging enabled on their device, there is a professional method of rebooting via a computer, which allows you to send a command to restart even in cases where the touchscreen is partially not working, but the system is not yet “dead” completely.
You'll need a computer with Xiaomi USB Drivers installed and an ADB (Android Debug Bridge) utility. Connect your phone to your PC via the original cable. If debugging is allowed, the computer will recognize the device. Open the command prompt or terminal in the ADB folder and enter a restart command.
adb rebootThis command sends a direct signal to the Android operating system to perform the reboot procedure, if the system responds, the phone will go into reboot instantly, and if the command does not execute and the message is displayed that the device is not available, then either the debugging is turned off or the system is getting stuck dead and does not process incoming requests.
- 💻 Install Platform Tools on your computer.
- 🔌 Connect your smartphone with the original cable.
- ⌨️ Enter the adb device command to check the connection.
- 🔄 Use the adb reboot command to restart.
Analysis of the causes of system freeze
Understanding why your Redmi 9 requires a forced reboot will help prevent a repeat of the situation in the future, most often due to a lack of RAM or a conflict of software components, when the free space in RAM runs out, the system begins to work unstable.
Another common cause is corrupted cache files or failed application updates, and sometimes conflict arises between the new version of MIUI and the old configuration data, and the table below outlines the main causes and likely solutions.
| Cause of failure | Symptoms | Decision |
|---|---|---|
| RAM overflow | Slow work, then hanging out | Close background applications, clear memory |
| Application error | Cyclical occurrence of errors | Remove or update the problem application |
| System update failure | Hanging on the logo | Resetting or flashing |
| Processor overheating | Interface braking, screen shutdown | Let the device cool, remove the case |
Failure prevention and optimization
To minimize the need for emergency measures, regular prevention is recommended. MIUI-based Android requires free space for temporary files. If internal memory is crammed, speed drops, and the risk of freezes increases exponentially.
Try to keep at least 10-15% of your internal memory free, remove unused apps regularly, and clean up the Downloads folder, and don’t ignore system updates, as they often contain bug fixes that affect your work stability.
⚠️ Note: Do not install applications from unknown sources (APK-These may contain malicious code that disrupts system processes and causes constant freezes.
Use built-in optimization tools. The Security app has a memory cleanup and system speed function, run it periodically, especially after using resource-intensive programs, which helps close the background processes that may have been stuck and consuming resources.
💡
Install the memory cleaning widget on the main screen - this will quickly free the RAM with one click, without going into the settings menu.
When the help of a service center is required
There are situations where software methods are powerless: If after a forced reboot the phone freezes again after a few minutes, or if it does not respond at all to the connection to the charger (there is no LED indication or vibration), the problem can be hardware.
There may be a power button failure (it may have stuck inside the case), battery failure or damage to the display plume, and serious motherboard problems such as CPU or memory dump can manifest as cyclic bootloops.
If you have tried all the methods, including discharging and ADB, but the Redmi 9 continues to behave inadequately, do not disassemble it yourself if you do not have experience.
💡
If the phone is warming off when connected to charging, it is a sign of a short circuit on the board that requires repair.
