Android has a tendency to accumulate software debris over time, which inevitably leads to lower performance and random errors in the interface. If your Redmi 9 Note starts to run slower, freeze at unexpected moments or consume more battery power than usual, then a radical solution will be to return to the original state. This procedure removes all user data, returning the software to the form in which it was immediately after buying the device in the store.
Before you decide to take such drastic action, it is necessary to clearly understand that resetting is an irreversible process of deleting information. You will lose all contacts, saved photos, videos, history of correspondence in messengers and installed applications if you do not take care of saving them in advance. In this article, we will discuss in detail all available methods, from the standard menu to hard reset through the engineering menu, so you can choose the most suitable for your situation.
It is important to note that the procedure does not require special technical skills or expensive equipment, however, requires attention to detail.After reset, the device will require you to enter the Google account that was the main one on the phone before cleaning, so make sure you remember the username and password.
Preparation of the device for complete reset
The first and most critical step is to back up your data, because once you click the confirmation button, it will be impossible to return files in the standard way. Use the built-in MIUI tools to create a backup to a cloud server or an SD card if it is installed in the expansion slot. It is also worth checking the synchronization of contacts with your Google account, as this is the most reliable way to save a phone book.
Make sure that the battery charge is at least 50-60% so that the formatting process is not interrupted due to discharge. During cleaning, the system performs intensive write and delete operations, which puts a high load on the power controller. If the phone turns off in the middle of the process, this can damage the system files and inability to further boot.
☑️ Checklist before reset
Be sure to disable all active Bluetooth connections with your smartwatch or headset, and break pairs with other devices if you plan to transfer the phone to another user.This will help avoid conflicts when reconfiguring the gadget in the future. Pay special attention to two-factor authentication: if you do not have access to the phone number, it is better to create recovery codes for important services in advance.
Reset method through the system settings menu
The safest and most recommended way to clean up is to use the operating system's standard interface, which allows the system to correctly complete all background processes and format memory partitions correctly. First, go to the main menu and find the Settings icon, which usually looks like a gear.
In the options list that opens, scroll down to About Phone, which contains basic information about the model and version of the software. This is where the hidden menu for memory management and reset is located. Click on it to reveal additional device management options.
- 📱 Find the Reset button at the bottom of the screen and click on it.
- 🗑️ Select the option to erase all data for complete internal memory cleanup.
- 🔒 Enter a pattern lock or digital screen lock pin to confirm access rights.
- ✅ Click the red button Reset in the dialog window that appears.
Once confirmed, the system will alert you that all data will be destroyed and request final confirmation, and will start a cleanup process that can take anywhere from minutes to half an hour depending on the amount of memory filled, during which time the Xiaomi logo or download animations can be displayed on the screen, which is normal behavior.

If you are planning to sell your phone, make sure to get it out. SIM-card before the procedure, so as not to lose personal contacts and data of the mobile operator.
Hard Reset with Recovery Mode (Recovery Mode)
If the operating system is not booting, the phone is stuck on the logo or the touch screen has stopped responding to touch, you will need to use Recovery Mode. This method allows you to reset at a lower level, bypassing the broken Android interface. To enter this mode, you need to completely turn off the device by holding the power button.
Once the screen goes out, simultaneously press the Up Volume and Power buttons. Hold them until the Mi logo appears, and then the power button can be released while holding the volume button. In a few seconds, the recovery menu will open, where the volume buttons (up/down) are controlled and the power button selects.
What to do if the Recovery menu does not open?
In the menu that opens, select Wipe Data, then confirm the choice with the Wipe All Data button. The system will again warn about the risks of loss of information. Once you have cleaned, select Reboot and then Reboot to System to restart in normal mode. The phone will be on longer than usual, since the initialization of the system occurs.
Delete Forgotten Passwords through Google Account
In situations where access to the phone is limited to a forgotten graphical key, but the device is connected to the Internet, you can use Google services for remote cleaning. This method is effective if the device has previously logged in to the account and enabled the device search function. Go to android.com/find from a computer or other smartphone.
Sign in to the same Google account used on the blocked Redmi 9 Note. Select your model from the device list and the map will show its current location (if geolocation is enabled).
⚠️ Note: Using this method will cause all data to be instantly deleted without recovery.The phone will only be reset once the internet connection is back up, so don't turn off the device.
Once the command is confirmed on the site, the phone will receive a reset signal and automatically restart in factory settings. This is one of the few ways to get around locking the screen without losing warranty, since it does not require interference with system partitions through third-party tools. However, if the phone is offline, the command will be executed the first time you connect to the network.
Solving Common Problems in Resetting
Even with strict adherence to the instructions, there may be unforeseen circumstances related to software errors or features of a particular firmware version. One of the common problems is the freezing of the cleaning process at a certain percentage or the endless restart of the device.
If, after a reset, the phone requires you to enter a password from a Google account that you don't remember or know, it's FRP. You can't get around it legally without the owner's data, which is an important security feature. Make sure you enter the account that was the main one before the reset.
| Problem. | Possible cause | Decision |
|---|---|---|
| The phone is stuck on the logo. | System file error | Hard Reset via Recovery |
| No resetting settings. | Lack of memory | Clean the app cache manually |
| Requires a password after resetting | FRP Protection (Google) | Enter the main account details |
| Sensor's not responding. | Driver failure | Resetting through buttons (Recovery) |
In rare cases, it may be necessary to flash the device through the computer using the Mi Flash Tool utility, but this is already a more complex procedure that requires unlocking the bootloader. For most users, the methods described above are sufficient. If the problems are of a hardware nature (for example, memory damage), a software reset will not help, and you will need to contact a service center.
Initial adjustment after cleaning
After the procedure is successfully completed and restarted, you will see a welcome screen with a choice of language. Select Russian and press Start. Then the system will prompt you to connect to an available Wi-Fi network, which is necessary to activate the device and check for security updates.
When you set up your Google account, enter your data. If you have previously backed up, the system will suggest restoring apps and settings from the cloud, a convenient way to quickly reclaim your environment, but recovering large amounts of data can take considerable time.
- 🛡️ Accept Google’s Terms of Service or skip this step.
- 📅 Set the current date and time if they are not automatically determined.
- 👆 Set up ways to unlock: fingerprint, face or pin code.
- 📲 Decide whether to restore applications from a past installation.
💡
Recovery from Google backup is the fastest way to get all apps and passwords back, but requires a stable Wi-Fi connection.
Once completed, the customizator will be placed on a desktop that will look almost the same as the day of purchase.It is recommended to immediately check for system updates in the About Phone menu, as important security patches may have been released during use. Now your Xiaomi Redmi 9 Note is running fast again and without unnecessary software debris.
