The MIUI operating system installed on the Xiaomi Redmi Note 9 Pro can accumulate software debris over time, leading to slowdowns or system errors. If your device starts to behave unstable, spontaneously reboot or simply works noticeably slower than in the first days after purchase, a complete data reset will be a radical solution, which will return the gadget to a factory state by removing all user files, applications and changed configuration settings.
Before you start taking action, you need to be clear about the consequences of this process: a full reset is an irreversible operation that erases absolutely all the contents of internal memory. Photos, contacts, correspondence in messengers and installed programs will be destroyed without the possibility of recovery by standard means, which is why the critical step is to pre-backup important data on the cloud service or computer.
In this article, we will take a look at all the ways available to return the Redmi Note 9 Pro to its original settings. We will look at the standard method through the system menu for those who have access to the interface, as well as more complex options through the Recovery menu for cases when the phone is locked or not booting. Following the step-by-step instructions, you can safely reanimate your smartphone and extend its effective life.
Preparation of the device for the discharge procedure
Start by providing a stable power source. The process of erasing data and reinstalling system files can take 10 to 30 minutes, and interrupting this process on a low battery charge can damage the bootloader. Make sure the battery level is at least 60%, and ideally connect the device to the original charger throughout the operation.
The second and most important step is to back up, and in the Xiaomi ecosystem, it’s convenient to use the built-in Mi Cloud or third-party services like Google Drive. USB-Be sure to export your contact list if it’s only stored in your phone’s memory and not synced to your Google account.
☑️ Preparation for discharge
Special attention should be paid to accounts. If the phone is activated with protection against theft or binding to Mi Account, the system after reset will require you to enter the username and password that were used before. Forgotten password can turn the device into a useless brick, so make sure you remember the login data or untie the device from the account in advance in the settings.
Reset via the system settings menu
The safest and easiest way to bring the Xiaomi Redmi Note 9 Pro back to factory settings is available right from the operating system, which is suitable for users who want to clean the phone before selling or fix software glitches that do not interfere with the interface.
To start, open the main menu and find the Settings icon. In the settings list, scroll down to About, which is where the basic system management tools are hidden. Find Reset, or Factory Reset, which is usually at the bottom of the list.
The system will offer several cleanup options. You can choose "Erase all data" to completely delete information or "Reset Wi-Fi, mobile Internet and Bluetooth settings" if the problem is only network connections. To completely clean, select the first option.
💡
Before pressing the final button, check again whether you have copied all important files to an external medium or to cloud storage.
After confirmation of action, the phone can request the input of a pattern lock, PIN-This is a security measure to prevent accidental or unauthorized reset, and once you enter the code, you start a preparation process that takes a few seconds, and then the device restarts and starts cleaning.
Alternative path through advanced settings
In some versions of MIUI firmware, the path to reset may be slightly different or hidden in a deeper menu.If you didn't find the reset item in the About Phone section, try going to the Advanced Settings menu. This section often contains additional tools for power users.
Inside the Advanced Settings menu, look for the Recovery and Reset section, where the functionality duplicates the main one, but sometimes allows you to access additional options, such as resetting application settings by default. Select the Reset option to continue.
The system (again) will alert you to the risks. Pay attention to the “Clean Internal Storage” box. If it is installed, all files, including music, downloads and app cache, will be deleted. If you plan to leave media files, this option can be removed, but a complete cleanup is recommended to completely solve the performance problems.
After pressing the confirmation button, a countdown (usually 10 seconds) will begin, during which you can cancel the operation. If you are confident in your decision, wait until the countdown is completed. The screen will go out, and the technical process of re-marking the memory parts begins.
Hard Reset via Recovery Mode
There are different situations: the phone can freeze on the logo, not respond to touch or forget the unlock password. In such cases, the standard menu is not available, and you have to use a recovery mode known as Recovery Mode. This is a low-level environment that boots independently of the main operating system.
To enter this mode on the Redmi Note 9 Pro, you need to turn the device off completely. Then press the Volume Up and Power button at the same time. Keep them clamped until the Mi logo appears, after which the power button can be released, while continuing to keep the volume.
What to do if the menu does not appear?
When the Main Menu appears (usually with a black background and yellow or blue text), the volume buttons (up/down) control the menu, and the power button confirms the choice. You need to find the Wipe Data item and select it.
Confirm the action by selecting Confirm. The process will go quickly. Once completed, the message Data wiped successfully. Select Back to Main Menu, then Reboot -> Reboot to System. The phone will reboot, and the initial setup will take longer than usual.
Remote reset via Google Find My Device
If a device is lost or stolen and you don't have physical access to it, but it has internet and geolocation enabled, you can reset remotely, using Google Find My Device, which lets you control your phone from any other gadget or computer.
Go to the official website of the service from any browser and log in to the same Google account that was used on the lost Redmi Note 9 Pro. In the list of devices, select your smartphone. Among the available actions (Block, Ring) will be the option “Clean the device”.
Once the command is confirmed, the phone will receive a signal to erase the data. Importantly, to be successful, the phone must be connected to a mobile network or Wi-Fi. If the device is offline, the command will be executed automatically as soon as it appears on the network, and this is an effective way to protect personal data from prying eyes.
It's worth noting that after such a reset, the device may be affected by FRP (Factory Reset Protection), which means that when turned on, the phone will require you to enter a password from a Google account that was previously synced with it, without which you will not be able to use the phone.
Solving problems after discharge
After the Xiaomi Redmi Note 9 Pro has successfully passed the reset procedure, users may face a number of nuances: first of all, the first download can last up to 10-15 minutes. Don’t panic if the screen is lit with a logo for a long time - the system is busy optimizing applications and creating new configuration files.
In some cases, you may need to re-authorize to Google services, if the phone says that “account is not found” or sync errors occur, check the date and time. After reset, these parameters may be lost, leading to a conflict of security certificates.
If the battery starts to run out faster than usual in the first days after the reset, that's fine. System and applications re-index files and download data. After 2-3 days of active operation, the power mode stabilizes, and the Redmi Note 9 Pro will work normally.
If the phone continues to behave incorrectly after reset (heats, turns off), the problem may lie not in the software part, but in the hardware, perhaps the battery has worn out or there are problems with the motherboard that the software reset cannot solve.
Comparison of data dumping methods
To make it easier for you to choose the right method, we have prepared a comparative table of methods, each of which has its advantages and limitations depending on the current situation with your device.
| Method | Access to the menu is required | File retention | Difficulty |
|---|---|---|---|
| Through Settings. | Yes. | No (complete removal) | Low. |
| Recovery Mode | No. | No (complete removal) | Medium |
| Google Find My Device | No (remotely) | No (complete removal) | Low. |
| Resetting network settings | Yes. | Yes (files remain) | Low. |
As you can see from the table, if you have access to the desktop, you'd better use the standard method through the settings. It's the most controlled process. Recovery mode is "heavy artillery" for emergencies when the interface doesn't respond.
Remember that after any type of reset, the security of your device depends on you: Set a strong password, set up biometric protection, and be careful when installing applications from unknown sources so that you don’t have to clean the system again.

Regularly cleaning the cache and removing unused applications can prevent the need for a complete system reset in the future.
