Reset Xiaomi Redmi Note 9 Pro 128GB to factory settings: 3 working methods

Introduction: Why is reset needed and when to apply it

Resetting the Xiaomi Redmi Note 9 Pro to factory settings is a radical but sometimes necessary solution to restore the smartphone to work, which removes all user data, applications and settings, returning the device to a “out of the box” state, most often resorted to in three cases: before selling the phone, in critical system failures or after unsuccessful experiments with firmware.

The Redmi Note 9 Pro 128GB (codenamed joyeuse) based on the Snapdragon 720G processor is stable, but even it is not immune to software conflicts. For example, after upgrading to MIUI 14, some users experience slowdowns, overheating or application errors, in which case the reset helps to “zero” accumulated bugs without contacting the service center.

It's important to understand that the procedure is not equivalent to flashing, it doesn't change the MIUI version or the kernel of the system, it only cleans the user partition. If the problem is hardware (for example, a faulty memory module or a damaged battery), reset will not help.

Preparation for resetting: what to do before the procedure

A misguided reset can result in the loss of important data. Before you start, take a few critical steps:

• 📱 Back up. Use the built-in Settings tool. → The phone. → Backup or third-party utilities like Mi Mover. Pay special attention to: Contacts (export to.vcf) Photos and videos (copy to PC or cloud) Messages (applications like.vcf) SMS Backup & Restore App Data (Game Progress, Notes)
• 🔋 Charge the battery to at least 60%. interruption of the process due to discharge can lead to a "brick" (inoperable state) of the device.
• 📋 Record your account information. After the reset, you will need to re-enter your username and password from Mi Account. If you forget the data, restore it in advance at account.xiaomi.com.
• 🔑 Make sure that there is no lock. If the phone is linked to a Mi Account and Find Device is enabled, you will need to enter a password from that account after the reset.

💡

If you are selling a phone, be sure to unplug it from Mi Account via Settings → Xiaomi Account → Delete your account. Otherwise, the new owner will not be able to activate the device.

Pay special attention to applications with two-factor authentication (for example, Google Authenticator or banking programs). Once reset, access to these will be lost if you do not transfer backup codes in advance. For Authenticator, you can use export through Settings → Export accounts (you need a password from Google Account).

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

This is the way to do it if the phone turns on, responds to touch, and you have access to the menu, and it's the easiest and least risky thing to do because it's controlled by the system.

1. Open the settings (cog icon on the desktop).
2. Go to the About Phone section. → Backup and reset.
3. Select Settings Reset.
4. The system will suggest you choose the type of reset: Reset all settings - deletes only settings, application data and accounts, but saves media files. Resets all data (full reset) - returns the phone to factory state, removing everything, including photos and videos.

Confirm the action by entering PIN-code.

Wait until the process is complete (usually takes 5-10 minutes) and the phone will reboot automatically.

If after resetting the phone requires you to enter a password from Mi Account, but you do not remember it, use the recovery function on the Xiaomi website. In extreme cases, you may need to contact the service center with a confirmation of purchase.

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

If the Redmi Note 9 Pro doesn’t boot, freezes on the logo or reboots cyclically, a Recovery Mode reset will help.This mode is sewn into the firmware and is available even in case of serious system failures.

1. Turn off the phone (if it freezes, hold the power button for 10-15 seconds).
2. Press the power and volume buttons up simultaneously.
3. Hold them until the Mi logo appears and vibrations (usually 5-7 seconds).
4. Release the buttons and you will see the Recovery menu in English.
5. Use volume buttons for navigation and power button to select the item.
6. Choose Wipe Data → Wipe All Data.
7. Confirm the action by selecting Confirm.
8. Once you have finished, select Reboot → Reboot to System.

Instructions:

1. Turn off the phone.
2. Press Power + Volume down until the Fastboot logo appears.
3. Connect the phone to the PC.
4. Open the command line (Win + R → enter cmd).
5. Check the connection command: fastboot devices If the device is displayed, type: fastboot erase userdata fastboot erase cache fastboot reboot

⚠️ Warning: If the phone doesn't respond after commands in Fastboot, don't disconnect it from the PC. Try re-entering the fastboot reboot command.

What to do after resetting: setup and recovery of data

After a successful reset, the phone will start in initial setup mode, just like after purchase.

1. Choose a language and region.
2. Connect to the Wi-Fi network.
3. Sign in to Mi Account (if the phone was tied).
4. Restore data from a backup (if it was created).
5. Update the system to the latest version of MIUI via Settings → About Phone → System Update.

If you have not created a backup copy, you can partially restore the data:

• 📸 Photo and video: Check the folder DCIM on a memory card (if inserted during resetting).
• 📞 Contacts: If they were synced to Google Account, they will be automatically restored after logging in.
• 🎮 Game progression: some games (e.g. Genshin Impact or PUBG Mobile) save data on servers. Log in through a linked account.

After discharge, it is recommended:

• Disable unnecessary system applications through Settings → Applications → Application Management.
• Set up battery optimization for critical applications (e.g. instant messengers).
• Install an antivirus (such as Dr.Web or Kaspersky) to check for recoverable files.

💡

After resetting the first 2-3 days, the phone can run slower than usual, which is normal: the system indexes files and optimizes background processes.

Common mistakes and their solutions

Even if you follow the instructions correctly, you can have problems, and let's look at the typical situations and how to fix them:

If after resetting the phone began to overheat or discharge quickly, check:

• 🔍 Background Processes: Open Settings → Battery → Battery usage and find apps with abnormal consumption.
• 📱 Updates: Is the latest version installed? MIUI.
• 🛠️ Hardware problems: if overheating is accompanied by blackouts, battery wear is possible (check the state in Settings) → The phone. → Battery status).
