How to Reset Xiaomi Redmi 9 to Factory Settings: The Complete Guide

Xiaomi Redmi 9 is one of the most popular budget smartphones, but even it is not immune to system failures, viruses or slowdowns.Resetting to factory settings helps return the device to its original performance, but only if done correctly. Wrong actions can lead to data loss or even "bricking" the phone.

In this article, you will find three proven ways to reset — through settings, Recovery mode and Fastboot. We will detail each method, point out pitfalls and give recommendations for saving important files. If your Redmi 9 freezes, does not turn on or just runs slowly, this guide will help bring it back to life.

Preparation for resetting: what to do necessarily

Factory reset is the complete removal of all data from the device. Even if you plan to reset the Redmi 9 due to minor lags, you can't do without backup.

• 📱 Save your contacts – export them to your Google account or to your website. SIM-map through the Contacts app.
• 📷 Copy photos and videos – use the cloud (Google Photos, Mi Cloud) or transfer files to your computer.
• 🔑 Remember passwords – after reset, you will have to re-enter data from Wi-Fi, accounts and applications.
• 📥 Download backup – Mi Account has a Backup feature (but it doesn’t save some system files).

Pay special attention to the associated Mi Account. If you forget your username or password, after resetting, the phone may be blocked due to the protection of the Mi Cloud Lock. To avoid problems, check:

• 🔒 Is your Xiaomi account linked to your device (check Settings) → Mi Account).
• 📧 Is there access to the email specified during registration.
• 📱 Is the phone connected to the Internet (after reset, you will need an account confirmation).

⚠️ Note: If you bought Redmi 9 handheld and do not know the details of your previous Mi Account, the reset may result in a complete lock of the device.

Method 1: Reset via the settings menu (the safest)

This is a method that works if the phone turns on and responds to touch, and it's the simplest and doesn't require any additional tools.

1. Open Settings (the gear icon on the main screen).
2. Go to the About Phone section (usually at the bottom of the list).
3. Select Backup and Reset → Resetting.
4. Click Reset your phone settings and confirm the action.
5. If requested PIN-code or pattern lock, enter it.
6. Wait until the process is complete (the phone will reboot automatically).

The whole process will take 5-10 minutes, and after the restart, you will be asked to set the phone as new, and if there is an error or the reset is interrupted, try other ways.

⚠️ Note: On some Redmi 9 firmware, Settings Reset may be elsewhere, such as Settings. → Additionally. → Recovery and reset. If you don't find the right section, search by settings (the magnifier icon at the top).

Method 2: Reset via Recovery Mode (if the phone is not turned on)

If Redmi 9 is stuck on the logo, does not respond to buttons or is locked with a pattern lock, resetting through Recovery mode will help.This method works even without access to the main system, but requires accuracy.

Step instructions:

1. Turn off the phone (press the power button for 10-15 seconds if it freezes).
2. Press the Power button + Volume up at the same time and hold for 10-15 seconds until the Mi logo appears.
3. Release the buttons and you will be taken to the Recovery Mode menu (black screen with blue inscriptions in English).
4. Use the up/down Volume buttons for navigation and the Power button for selection.
5. Select Wipe Data → Wipe All Data (complete reset).
6. Confirm the action by selecting Confirm.
7. Once you have finished, select Reboot → Reboot to System.

If the Recovery menu doesn’t have Wipe All Data, look for Factory Reset or Clear Data – the names may vary depending on the firmware version.

Method 3: Fastboot Reset (for power users)

This is the most radical method, and it requires you to connect your phone to your computer, and it's used if you:

• 🔄 Recovery Mode is not available or working.
• 📱 Phone does not turn on at all (black screen, no reaction to buttons).
• 🔧 You need to reflash the device after a failed update.

To reset via Fastboot, you will need:

• 💻 Computer with Windows/Linux/macOS.
• 🔌 Cable USB (preferably original).
• 🛠️ Mi Flash Tool or Fastboot Teams.
• 📄 Firmware for Redmi 9 (you can download on the official website of Xiaomi).

Step-by-step:

1. Turn off the phone.
2. Press the Power button + Volume down for 10-15 seconds until the screen with the hare in the hat-eared (Fastboot mode) appears.
3. Connect the phone to the computer.
4. Download and install the Mi Flash Tool.
5. In the program, click Select, select the downloaded firmware (file with the extension.tgz or.zip).
6. Press Refresh – your Redmi 9 should appear in the list of devices.
7. Select Clean All mode and press Flash.
8. Wait until it is completed (usually 5-10 minutes).

If you don't want to reflash the phone completely, you can use Fastboot commands to reset.

1. Open the command line (Windows) or the terminal (Linux/macOS).
2. Enter the commands: fastboot devices (should display the serial number of your phone) fastboot erase userdata fastboot erase cache fastboot reboot

⚠️ Attention: fastboot erase commands permanently delete data from the partition. If you make a mistake with the partition (for example, enter a fastboot erase system), the phone may stop loading!

💡

If the phone doesn’t turn on after reset via Fastboot, try flashing it again using the Mi Flash Tool, selecting Clean All and Lock mode.

What to do after resetting: setup and recovery of data

After a successful reset, Redmi 9 will turn on as new.

1. Choose a language and region.
2. Connect to Wi-Fi.
3. Sign in to your Mi Account (if it was tied before the reset).
4. Restore data from a backup (if it was created).

Here are some tips for optimal customization:

• 🔋 Turn off unnecessary autoboots: Go to Settings → Annexes → Autostart and disable autoboot for underutilized programs.
• 📶 Set up a mobile network: if there is no internet after reset, check APN-settings in the settings → SIM-maps and mobile networks → Access points (APN).
• 🔒 Activate the protection: install PIN-code or pattern lock in Settings → Screen locking.
• 📱 Update the firmware: check for updates in Settings → The phone. → Updating the system.

If you restore data from a backup, consider:

• Photos and videos can be returned from Google Photos or Mi Cloud.
• Contacts are automatically synced if you are logged in to the same Google account.
• SMS and call log are restored only if a local backup has been created through Settings → Backup.

💡

After reset, Redmi 9 can run faster, but over time, the lags will return if you do not monitor the free disk space and background processes.
