How to make factory settings on Android Redmi 9

Smartphones series Redmi 9 from Xiaomi have earned popularity due to their affordable price and functionality, however, over time, any device may begin to work slower or produce software errors. Often, users are faced with the need to return the gadget to its original state before selling, transferring to another person, or to eliminate critical failures in the MIUI operating system. A full reset procedure, known as a Hard Reset or Factory Reset, is the most radical but effective way to solve many software problems.

It is important to understand that performing this operation will completely delete all user information from the internal storage of the device. This means that photos, contacts, messages, installed applications and their data will be irretrievably lost if you do not take care of creating a backup copy in advance. In this article, we will analyze in detail all the available methods of returning factory settings to Redmi 9, consider the nuances of working with a Google account and answer frequently asked questions that arise during the system recovery process.

Preparing the device for a full data reset

Before Before you get active in the settings menu or recovery mode, you need to complete a number of critical preparatory steps. Ignoring this step may result in you getting a “brick” blocked by Google protection after a reboot, or simply losing valuable family archives. First of all, make sure that the battery level is at least 60-70%, since the process of formatting the data partition requires stable power and can take from 10 to 30 minutes depending on the amount of information.

The second mandatory step is to create a backup copy of all important data. You can use cloud services, such as Google Drive or a proprietary cloud Mi Cloud, or manually copy the files to your computer via a USB cable. Pay special attention to exporting contacts and saving passwords for important applications, since after clearing the memory they will not be restored automatically without prior synchronization.

⚠️ Attention: If the Find My Device function is enabled on your device and a Google account is linked, be sure to remember the username and password for it. After the reset, the system will require authorization in this account to confirm ownership, and without this data the phone will remain locked.

It is also recommended to remove the microSD memory card if it is installed in the slot. Although modern versions of MIUI usually ask for confirmation before formatting the external card, physically removing the media guarantees 100% safety of your files on it and eliminates an accidental system error that could affect the external drive when cleaning the internal storage.

Method one: reset through the system settings menu

The most secure and simple method of returning Redmi 9 to its original state is available directly from a running operating system. This method is ideal when the smartphone turns on, the screen responds to touches, and you can freely navigate the interface. The algorithm of actions may differ slightly depending on the MIUI firmware version (for example, MIUI 11, 12 or newer), but the general logic remains the same for the entire Xiaomi ecosystem.

First, open the “Settings” application on the main screen or in the notification shade. Scroll down the list of options to the About Phone or Advanced Settings section, where system management features are usually hidden. In new versions of the shell, the path often looks like Settings → About phone → Reset settings, while in older versions it may be Settings → Advanced settings → Recovery and reset.

After going to In the desired section, you will see the item “Reset settings” or “Delete all data”. By clicking on it, the system will show a detailed list of what exactly will be deleted: applications, photos, music, Wi-Fi and Bluetooth settings. This is the last moment to change your mind. If you are confident in your decision, click the “Reset settings” or “Clear all data” button, after which you may be required to enter a pattern, PIN code or screen unlock password to confirm the owner’s identity.

After confirmation, the smartphone will automatically reboot and begin the cleaning process. The screen may display a logo Redmi or android with a progress indicator. Do not try to interrupt this process by pressing the Volume or Power buttons, as this may damage the file system. Upon completion of the procedure, the device will boot into the initial setup mode, as if you just took it out of the box.

Method two: Hard Reset via Recovery mode

If your Redmi 9 is stuck on the logo, does not respond to touch input, or reboots endlessly, the standard method through the settings will become unavailable. In such situations, Recovery Mode comes to the rescue, which allows you to perform a hardware reset using only physical control buttons. This method is universal and works even with serious software failures.

To enter Recovery mode, first turn off your smartphone completely. Wait until the screen goes dark and the motor vibration stops. Then hold down the volume up button (Volume Up) and the power button (Power) at the same time. Hold both keys until the logo Mi or Redmiappears, after which you can release the power button while continuing to hold the volume key until the main Recovery menu appears.

In Recovery mode, the touch screen usually does not work, so navigation is carried out with the volume buttons (up and down), and the selection of an item is confirmed with the power button. You need to find item Wipe Data or Clear Data. Depending on the version of Recovery, this item may be in a submenu or immediately available. Select it and confirm the action by selecting Wipe All Data.

Action in Recovery	Navigation button	Confirmation button	Result
Selecting a menu item	Volume Up/Down	-	Move the cursor
Confirm selection	-	Power	Enter submenu or start
Reset data (Wipe Data)	Volume	Power	Start formatting
Reboot	Volume	Power	Login

The system will ask for final confirmation, often requiring you to select the item Confirm again. After this, the cleaning process will begin, which will take a few minutes. Once complete, you will see the message “Data wiped successfully.” Now select Back to Main Menu, and then Reboot → Reboot to System. The smartphone will reboot and begin the lengthy procedure of first initializing the system.

What to do if Recovery is in Chinese?

Sometimes on devices with Chinese firmware, the Recovery menu is displayed in hieroglyphs. In this case, be guided by the icons or the number of items: usually the data reset item is second or third from the top. If you are not sure, it is better to look for a photo of the interface for your specific version of MIUI on the Internet before proceeding.

Google FRP protection and Mi Accounts

One ​​of the most common problems after resetting the settings on Android is FRP (Factory Reset Protection) blocking. This security feature was introduced by Google to protect against theft: if a Google account was added to the phone, then after resetting the device, it will require you to enter the password for this account when setting up for the first time. This is done so that an attacker cannot simply erase the data and sell the stolen phone.

Owners Redmi 9 should also take into account the connection to the Xiaomi ecosystem. If the “Find my device” function was enabled on the device, then after resetting the phone will ask for the password for the Mi account. Without entering the correct data, activation of the smartphone will not be possible. Many users forget this data, as they create it spontaneously when purchasing, which subsequently leads to difficult unlocking situations. Mi Account and the “Find device” function, then after resetting the phone will ask for a password for the Mi account. Without entering the correct data, activation of the smartphone will not be possible. Many users forget this data because they create it spontaneously when purchasing, which subsequently leads to difficult unlocking situations.

• 🔐 Be sure to check which accounts are linked to the device in the section Settings → Accounts and synchronization before resetting.
• 📝 Write down your logins and passwords on paper or in a reliable password manager that you can access from another device.
• 🚫 Do not try to bypass FRP protection using dubious apps from the Internet - this can lead to a complete blocking of the device at the server level.

If you buy a used Redmi 9 phone, always ask the seller to reset the settings in front of you or make sure that he has signed out of all accounts before handing over the device. Buying a phone with activated FRP or Mi Cloud protection without the ability to enter the previous owner's password turns the gadget into a useless piece of plastic and metal.

Initial setup after formatting

After successful completion of the reset and reboot process Redmi 9 it will greet you with a language selection screen. This stage is familiar to anyone who has ever set up a new smartphone, but it requires care. Select the language you want, connect to a Wi-Fi network to speed up the loading of Google services and check that your device is activated. If a Wi-Fi network is unavailable, you can use the mobile data, but this may waste traffic.

The system will offer to restore data from a backup copy. If you previously created a backup in Google Drive or Mi Cloud, now is the time to enter your credentials and start the process of restoring contacts, call history and the list of installed applications. However, it is worth remembering that the files themselves (photos, videos) are often not restored automatically through the standard setup wizard and require manual copying if you have not used full synchronization.

Next, follow the prompts of the setup wizard: set up a fingerprint or facial recognition, select a navigation method (gestures or buttons), set up a theme. At this stage, it is also useful to immediately check for system updates by going to Settings → About phone → MIUI versionto make sure that the latest security patches are installed on the device.

⚠️ Attention: The interface and menu item names may vary slightly depending on regional firmware version (Global, EU, Russia, India). If you do not find any item, check the official manual for your specific device modification.

Solving common problems after a reset

Sometimes after performing a Factory Reset, users encounter unusual situations that can cause panic. For example, the phone may hang on the logo for a long time when it first boots. This is normal: the system needs time to optimize applications and rebuild system caches. The first boot process after a reset can take anywhere from 5 to 15 minutes, so be patient and don't try to reboot your device every couple of minutes.

Another common problem is rapid battery drain in the first days after the reset. This is because the system indexes files, downloads application updates, and syncs data in the background. Typically, after 2-3 days of active use, autonomy returns to normal levels. If the phone gets hot or discharges after a week, perhaps one of the restored applications is causing a conflict.

In rare cases, after a reset, the network may disappear or Wi-Fi may stop working. Most often, this can be solved by simply restarting the device again or resetting the network settings (Settings → Connectivity and sharing → Reset Wi-Fi, mobile network and Bluetooth settings). If the problem persists, you may need to flash the device via a computer using the Mi Flash Tool, but this is a procedure for advanced users.

Frequently asked questions (FAQ)

Will information be deleted from the microSD memory card when resetting the settings?

What is FRP Lock and how to remove it?

FRP Lock is an indicator of the Google reset protection status. If it is active (ON), it means that a Google account is linked to the device. You can legally remove it only by entering the password for this account after the reset. Attempts to programmatically disable this protection often lead to damage to the device and are not recommended for ordinary users.

How long does the reset process take on Redmi 9?

The data formatting itself usually takes from 2 to 5 minutes. However, the complete procedure, including rebooting, optimizing applications and initially configuring the system to a working state, can take from 15 to 30 minutes depending on the speed of the memory card and the amount of previously stored data.
