How to reset Redmi 9 Pro to factory settings: 3 proven methods

Resetting Xiaomi Redmi 9 Pro to factory settings is a radical but effective way to return your smartphone to its former performance, eliminate software glitches, or prepare the device for sale. However incorrect reset can lead to the loss of important data, account blocking Mi Account or even bricking of the phone. This article will help you avoid mistakes and complete the procedure as safely as possible.

The reset process to Redmi 9 Pro has nuances related to the version MIUI, bootloader unlock status and linked account Xiaomi. We will look at three official methods: through system settings, mode Recovery and Fastboot, and also look at how to minimize risks and what to do if something goes wrong.

Before you begin, answer the key question: why do you need a reset? If the goal is to free up memory, clearing the cache or deleting unnecessary applications may be enough. If your phone is slow due to viruses, try anti-virus scanning first. Resetting to factory settings is “heavy artillery” and should only be used in case of serious problems.

1. Preparing for a drop: what needs to be done IN ADVANCE

Dropping without preparation is like jumping with a parachute without checking the lines. Even if you are sure that there is no important data on the phone, missed step it can lead to problems. Let's start with the most important thing - backup.

There are several built-in tools for backup: Redmi 9 Pro Several backup tools are built in:

• 📱 Local backup: Settings → About phone → Backup and reset → Local backup. Saves contacts, messages, system application settings, but does not touch photos and videos.
• ☁️ Xiaomi Cloud: requires a linked account Mi Account and enough space in the cloud (5 GB is given for free). Suitable for contacts, notes, call history.
• 🖥️ Computer: the most reliable option. Connect your phone via USB in File transfer (MTP) mode and manually copy folders DCIM (photo/video), Downloads, Documents and other important data.

Pay special attention applications with two-factor authentication (for example, Google Authenticator, Telegrambanking applications). If you do not save backup codes or do not unlink your device in advance, access to your accounts may be lost! For Google Authenticator there is a function for exporting codes (password required), and in Telegram you can enable cloud chat backup in Settings → Chat backup.

⚠️ Attention: If the function is enabled on the phone "Device protection" (in some versions MIUI), after resetting you will need to enter the password from the last account Googleassociated with the device. Make sure you remember it or disable protection in advance in Settings → Google → Security.

Equally important check the battery charge. The reset process after Recovery or Fastboot can take up to 10-15 minutes, and if the phone runs out of charge at this moment, the consequences will be unpredictable. The optimal charge level is at least 50%, but it is better to strive for 70–80%.

2. Method 1: Reset through system settings (the most secure)

This method is suitable if the phone turns on, you remember the screen unlock password, and there are no critical failures MIUI. The main advantage is simplicity and minimal risks.

Step by step instructions:

1. Open Settings (gear icon on the main screen or in the application menu).
2. Scroll down and select About phone.
3. Tap on the item Backup and reset.
4. Select Reset settings (in some versions MIUI can be called Reset all settings or Restore factory settings).

6. Confirm the action by entering Password/pattern unlock screen.
7. Press Reset and wait for the process to complete (usually takes 3-5 minutes).

After rebooting, the phone will turn on welcome screen, as after purchase. If at the setup stage the system asks you to enter account details Mi Accountthat was linked earlier, use the same login and password. This normal protectionand not a lock.

⚠️ Attention: If after resetting the phone requires an account Mi Accountthat you do not remember, do not try to enter data at random. After 5 unsuccessful attempts, the device will be blocked for 24 hours. In this case, only an official contact with support will help Xiaomi with proof of purchase.

This method does not affect the content microSD memory cards (if it is installed), but some system files on it may become inaccessible. If the card was used as Internal memory (function Adoptable Storage), its data will be erased along with the main memory.

3. Method 2: Reset via Recovery (if the phone does not turn on)

If Redmi 9 Pro stuck on the logoit constantly reboots or does not respond to touches, a reset via Recovery Mode. This mode is built into the firmware and is available even in case of serious system failures.

To enter Recovery:

1. Turn off the phone (if it is frozen, hold down the power button for 10-15 seconds).
2. Press and hold simultaneously Power button + Volume up button.
3. As soon as the logo appears on the screen Mi, release the Power button, but continue to hold Volume +until you see the menu Recovery.

In the menu Recovery control is carried out with the volume buttons (Volume + - up, Volume - - down), and selection is done with the power button. The interface can be in English or Chinese (depending on the version MIUI), but the necessary items can be easily recognized by the icons:

• 🔄 Wipe Data (or Clear Data) - full reset settings.
• 📱 Wipe All Data — clearing all data (analogous to a factory reset).
• 🔧 Reboot —reboot the phone.

Select Wipe All Data, confirm the action (usually you need to select Confirm or Yes), and wait for completion. The process may take up to 10 minutes - do not interrupt it! After cleaning, select Reboot to System to reboot.

⚠️ Attention: In some cases, after resetting through Recovery the phone may boot into Fastboot Mode (a black screen with a rabbit and the inscription FASTBOOT). This is not a mistake! Just select Reboot System with the power button.

If the menu Recovery is in Chinese, be guided by the location of the items:

• The first item is reboot (Reboot).
• The second point is data reset (Wipe Data).
• The third point is connecting to a PC (Connect with MIAssistant).

What to do if Recovery does not open?

If after holding Power + Volume + the phone vibrates, but the menu does not appear, try:

1. Repeat the combination, holding the buttons longer (up to 20 seconds).

2. Connect the phone to charge and try again.

3. data-i="188">(in rare cases, an alternative input works). Power + Volume - (in rare cases, an alternative input works).

If all else fails, the only option left is through Fastboot (see the next section).

4. Method 3: Reset via Fastboot (for experienced ones). users)

The method via Fastboot is the most radical and requires connecting the phone to a computer. It is useful if:

• 🔄 Recovery is inaccessible or damaged.
• 📱 The phone is blocked by an account Mi Account after an unsuccessful reset.

To work you will need:

• 💻 A computer with Windows (or Linux/macOS with installed drivers ADB/Fastboot).

• 📦 Utility Mi Flash Tool (for firmware) or ADB/Fastboot (for reset).

Instructions for resetting via Fastboot:

1. Turn off the phone.
2. Press Power button + Volume – until the screen with a rabbit in a hat with earflaps appears (FASTBOOT).
3. Connect your phone to the computer.

   fastboot devices

   fastboot erase userdata
   fastboot erase cache
   fastboot reboot
