Xiaomi Redmi Note 9 Pro is one of the most popular mid-range smartphones, but even it sometimes requires a reboot. The reasons can be different, from banal interface hanging to critical errors after the MIUI update. In this article, we will analyze all possible ways to reboot, from the standard menu to forced reboot through hardware buttons and even using ADB.
It's important to understand that not every reboot is equally useful, for example, a soft reboot (via the menu) saves all the time data and cache, whereas a hard reset (via the buttons clamping) can interrupt the background processes, and we'll look at each method in detail, its implications and when it's really needed.
1. Standard reboot via the settings menu
The safest and most recommended way is to use built-in MIUI features. It is suitable if the smartphone responds to touch, but works unstable (for example, brakes or overheats).
Instructions:
- 📱 Open Settings (cog icon on the main screen).
- 🔄 Scroll down and select About Phone.
- 🔧 Slip on Reboot (in some versions) MIUI This can be called a reset system).
- ✅ Confirm the action by pressing OK in the dialog window.
This method takes about 20-30 seconds and does not affect user data, but if the smartphone freezes tight (does not respond to touch or power button), you will have to use alternative methods.
💡
If the smartphone brakes again after rebooting through the menu, try clearing the cache in the Settings → Storage → Clear the cache section. This will delete temporary files without losing personal data.
2. Forced button reboot (Hard Reboot)
When the Redmi Note 9 Pro freezes completely — doesn't respond to the sensor, doesn't turn off the power button — it requires a hardware reset, which simulates battery extraction (although it's not removable in modern smartphones) and resets all current processes.
How to do this:
- 🔋 Press the power button and the volume button at the same time.
- 🕒 Hold them for 10-15 seconds until the screen goes out and the Redmi logo appears.
- ⏳ Release the buttons and wait for the system to fully boot (may take up to 1 minute).
⚠️ Warning: This method interrupts all background tasks, including unsaved data in applications (e.g., draft messages or game progress!
Close all important applications (if you have time)
Make sure the battery is at least 20% charged.
Remove the case (it can block access to the buttons)
Remember which apps were opened (to recover from a reboot)

3.Reboot to Recovery and Fastboot Mode
If the smartphone is turned on but not working properly (e.g., cyclically restarting or producing boot errors), it may be necessary to reboot to Recovery or Fastboot, which allows you to reset settings, install an update, or diagnose hardware problems.
How to get in to Recovery:
- 🔄 Turn off the phone (press the power button for 5 seconds).
- 🔧 Press the power button. + Increase volume and hold until a menu with the Mi logo appears.
- 📱 In the Recovery menu, use volume buttons for navigation and power button to select an item.
How to get into Fastboot:
- 🔄 Turn off the phone.
- 🔧 Press the power button. + reducing the volume before the appearance of the screen with a rabbit in the hat-eared (symbol Fastboot).
⚠️ Note: Fastboot mode does not recommend connecting your phone to your PC unnecessarily - this can cause accidental flashing or data reset. Use it only to diagnose or update software via the Mi Flash Tool.

4.Reboot via ADB (for advanced users)
If you are familiar with Android Debug Bridge (ADB), You can restart your smartphone through the command line, which is useful when the sensor is not working, but USB-debugging was included earlier.
Instructions:
- 🖥️ Connect the Redmi Note 9 Pro to the PC USB-cable.
- 📂 Open the command line (Windows) or the terminal (macOS/Linux) file ADB.
- 🔧 Enter the command to check the connection: adb devices Must appear serial number of the device.
- 🔄 Run the reboot command: adb reboot For reboot in Recovery: adb reboot recovery In Fastboot: adb reboot bootloader
If the adb device command doesn’t show your device, check if USB debugging is enabled in the developer settings (Settings → About Phone → MIUI version – tap 7 times, then go back to Additional → For Developers).
5. Automatic reboot on schedule
MIUI has an inbuilt auto-reboot feature that can be useful for regular refreshing, especially if you notice your smartphone starting to brake after days of continuous operation.
How to set up:
- ⚙️ Go to Settings. → Additionally. → Automatic reboot.
- 🕒 Turn on the feature and set a time (e.g. 3:00 a.m. when the phone is not normally used).
- 📅 Choose the days of the week (recommended daily or once every 2 days).
Advantages of this method:
- ✅ Cleaning RAM without your involvement.
- ✅ Preventing the accumulation of temporary files.
- ✅ Improved productivity over long periods of time.
⚠️ Warning: If you use your phone as an alarm clock, make sure that the automatic reset does not coincide with its setting.

6.Reboot in case of critical errors (bootloop, black screen)
If the Redmi Note 9 Pro is in a bootloop cycle or shows a black screen without responding to the buttons, standard methods won’t help, and in such cases, a deeper diagnosis is required.
Possible causes and solutions:
| Symptoms. | Possible cause | Decision |
|---|---|---|
| Cyclical reboot (Redmi logo appears over and over) | Damage to system files after update | Fastboot flash or reset via Recovery |
| Black screen, but the phone vibrates when you press the buttons | Problems with the display or plume | Connect to a PC and check through ADB or carry to the service |
| The phone warms and turns off 5-10 seconds after turning on | Processor overheating or battery failure | Let cool, check the charger, when repeated - battery replacement |
| Hangs on the Fastboot screen after a failed firmware | Incompatible version of the software or interrupted update | Swipe the official firmware through the Mi Flash Tool |
If none of the methods worked, it is likely a hardware problem (such as damage to the motherboard or battery), in which case it is better to contact the Xiaomi service center.
💡
When bootlooping, DO NOT try to turn on your phone repeatedly, which can worsen memory damage. The best solution is to try to log into Recovery once, if you can't, stitch through Fastboot.
7. Frequent mistakes and how to avoid them
Many users make errors when rebooting, which leads to additional problems.
- 🔋 Rebooting when the battery is low (less than 10%) can lead to a bootloop if the process is interrupted due to a power outage.Always charge your phone to at least 20% before a forced reboot.
- 🔧 Using informal firmware often causes a cyclical reboot. If you installed custom software, go back to stock firmware via Fastboot.
- 📱 Clicking random buttons in Recovery can cause a data reset.In this menu, never choose Wipe Data without the need to.
If you are not sure about your actions, it is better to seek help from a specialist. Mismanipulation of firmware or hardware buttons can turn a temporary problem into irreversible.
