How to reboot Xiaomi Mi 9T Pro: 5 working ways

Xiaomi Mi 9T Pro (also known as Redmi K20 Pro) is a powerful smartphone with the flagship Snapdragon 855 processor, but even it sometimes hangs or requires a forced reboot. System freeze, errors after the MIUI update, or a banal “black screen” – these are problems that many owners face. In this article, we will analyze all possible methods of rebooting, from standard to emergency, including working with Recovery Mode and Fastboot.

It is important to understand the difference between the types of reboot: soft is suitable for most situations where the phone responds to presses, and hard or reset via Recovery will be required when completely locked, and we will also look at how to avoid data loss and what to do if the smartphone does not turn on after the reboot.

1. Standard reboot (soft restart)

If the Mi 9T Pro is working but it is slowing or glitching, the first thing you can do is try the classic menu reboot, which saves all the data and settings by simply restarting the operating system.

Instructions:

• 📱 Hold the power button (on the right sidebar) for 2-3 seconds.
• 🔄 In the menu that appears, select “Reboot” (or “Restart” in English firmware).
• ⏳ Wait until the process is complete (usually 30-60 seconds).

If the screen doesn't respond to touch, but the power button is working, try holding it for 10 to 15 seconds, which will force the device to turn off. After vibration, release the button and turn on the smartphone again.

💡

If problems persist after the reboot, check for free space in memory (Settings → Storage). A filled storage often causes lags.

2. Hard reboot (when getting stuck)

When the Mi 9T Pro is completely frozen and does not respond to either the screen or the buttons, a forced restart is required, which simulates battery extraction (although it is not removable in the Mi 9T Pro) and resets all temporary processes.

How to do this:

• 🔋 Hold the power button. + increase volume simultaneously.
• ⏱️ Hold them for 15-20 seconds until the screen goes out and the smartphone vibrates.
• 🔄 Release the buttons and wait 10 seconds, then turn on the device with the power button.

⚠️ Attention: Frequent hard reboots can damage the file system. Use this method only as a last resort.

If after a hard reboot the phone does not turn on, connect it to charging for 10-15 minutes - perhaps the battery is completely discharged during the freeze.

3.Reboot via Recovery Mode

Recovery Mode is a service mode that allows you to reset, clear the cache or restart your smartphone if standard methods do not work. On the Mi 9T Pro, there are two types of Recovery: stock (from Xiaomi) and custom (for example, TWRP).

How to log in to Recovery:

1. Turn off your smartphone (hold the power button for 10+ seconds if it freezes).
2. Press the power + volume button and hold until the Mi logo appears.
3. Release the buttons and you will see a menu with an android and the words “No command”.
4. Press the power button briefly, then increase the volume to open the menu.

In the Recovery menu, use the volume buttons for navigation and the power button for selection.

• 🔄 Select "Reboot system now».
• 🧹 If your phone is slowing down, pre-select “Wipe cache partition” (this won’t delete your data, only temporary files).

4.Reset to factory settings

If the Mi 9T Pro is constantly rebooted or not turned on after the upgrade, a full reset may be required.This method deletes all data, including apps, photos and accounts, so use it only as a last resort.

How to reset your settings through Recovery:

1. Enter Recovery Mode (see Section 3).
2. Select "Wipe data» → «Wipe All Data».
3. Confirm the action (usually you need to enter a PIN or password if it has been set).
4. After reset, select “Reboot system now”.

⚠️ Note: After the reset, the smartphone will require data input from the Mi Account account, if the previously activated function “Device Protection” without this data, it will be impossible to unlock the phone!

If you have forgotten the Mi Account, try to restore access through account.xiaomi.com before making the reset.

Make a backup through Settings → Additional → Backup

Remember the username/password from Mi Account

Make sure the battery is at least 50% charged

Disable your Google account (if you plan to sell your phone)-->

5.Reboot via Fastboot (for power users)

Fastboot is a firmware mode that allows you to control your smartphone from your computer via the adb command. This method is useful if the Mi 9T Pro does not load even in Recovery or you need to reflash the device.

What you need:

• 💻 Computer with installed Xiaomi drivers and tools ADB/Fastboot.
• 🔌 Cable USB Type-C (preferably original).
• 🔋 Battery charge of at least 30%.

Instructions:

1. Turn off your smartphone.
2. Press the power + volume button before the screen with the hare in the hat appears (Fastboot logo).
3. Connect the phone to the computer.
4. Open the command line (cmd) and type: fastboot devices If the device is determined, enter the command to reboot: fastboot reboot

To reset to factory settings via Fastboot, use the command:

fastboot erase userdata


fastboot erase cache




fastboot reboot

⚠️ Attention: Fastboot erase commands permanently delete data. Don't use it unless you're sure you need it!

6.Reboot with ADB (without loss of data)

If the smartphone is powered on but not running smoothly, you can reboot it via ADB (Android Debug Bridge) without losing data.This method is useful when a standard reboot is not available due to an interface failure.

Steps:

1. Activate Developer Mode: Go to Settings → About Phone → MIUI Version and tap it 7 times.
2. Return to Settings → Additional → For developers and enable “Debugging by USB”.
3. Connect your smartphone to your computer and confirm the debugging permission.
4. In the command line, type: adb reboot

If you need to clear the cache without resetting data, use:

adb shell


su




rm -rf /cache/*

💡

USB debugging is disabled after a hard reboot. If your smartphone is frozen, unlock it in the standard way first, then activate ADB again.
