βοΈ Checklist before reset
Method 1: Reset via the settings menu (standard method)
The safest and easiest way to return to factory status is available right from the operating system that is running.This method is suitable for most users who want to clean the phone before selling or eliminate small software glitches. First, go to the main menu and find the Settings icon, usually located at the top of the screen or in the tool folder.
In the list of options that opens, you need to scroll down to About Phone, and that's where the basic information about the firmware version, the processor, and, importantly for us, the reset function is concentrated. In some versions of the MIUI shell, this item may simply be called "Advanced Settings," but the navigation logic remains similar.
Find the Reset line and click on it. The system will offer two options: Reset all settings (without deleting photos and contacts) and Erase all data (full format). After pressing the button to erase all data, the phone will request confirmation of the action and possibly enter PIN-screen-lock.
| Parameter | Meaning/Action | Risk of data loss |
|---|---|---|
| Resetting settings | Return of network settings, calls, alarms | Low (photos and contacts will be maintained) |
| Erase all data | Full formatting of the Userdata section | Tall (all removed) |
| Cleanup SD-map | Optional formatting of the flash drive | Medium (only files on the map) |
Once confirmed, the phone will restart and start the cleaning process, which can take 5 to 15 minutes depending on the amount of memory filled.Do not try to interrupt this process or remove the battery if it was removable. Upon completion, the Redmi 9A will turn on as new, suggesting you choose a language and connect to Wi-Fi.

Method 2: Hard Reset with Recovery Mode
If your smartphone doesn't turn on, you're stuck on your logo, or you don't have a touch screen that responds to touch, you'll need to use control buttons, a technique called Hard Reset, which allows you to log into a special recovery menu even when your operating system is not working, and you'll need to shut down the device completely by holding the power button.
To enter Recovery mode on Xiaomi Redmi 9A, you need to simultaneously press two buttons: Volume Up (+) and Power. Hold them until the Mi logo appears, after which the power button can be released, continuing to hold the volume key. In a few seconds, the Recovery menu will appear on the black background.

Reset by Find My Device (Remote Method)
In situations where you've forgotten your pattern lock or unlock password, but your phone is connected to the Internet, you can use Google, which is effective if your smartphone screen is broken, but the system is working, and you'll need a computer or other smartphone with access to the network.
Go to the official Find My Device website and log in to the same Google account used on the blocked Redmi 9A. In the list of devices, select your model.
Once the command is confirmed, the phone will receive a reset signal, and it's important to understand that to execute this command, the gadget must be online.

You can choose specific types of data to restore: contacts, messages, list of installed applications, which will allow you to quickly return personalization of the interface without manually installing each application.
Pay special attention to system component updates. During the first minutes of operation, the phone can start downloading security updates and patches for the MIUI shell.

Possible problems and solutions
Despite the simplicity of the procedure, users may face difficulties. One common problem is cyclic restart (bootloop), when the phone is constantly hanging on the Mi logo.

Attempts to bypass this protection by third-party programs can lead to the device being permanently locked.
