Xiaomi’s Redmi series is famous for its availability and functionality, but over time, even the most reliable devices can start to work slower. If your Redmi 9C is often hanging, glitching, or you plan to sell the gadget, the most effective solution is a complete return to the original state, which will delete all user data and return the system to its original freshness.
The reset procedure, known as Hard Reset or Factory Reset, affects all parts of internal memory. Before you start active actions, you need to be clear about the consequences: personal photos, contacts, messages and installed applications will be irretrievably lost if you do not back up in advance. In this article, we will discuss in detail all the stages of preparing and executing a system rollback.
There are two main ways to do this: through the regular Android settings menu and through the special Recovery engineering menu. The choice of method depends on whether the device has access to the desktop and menu. We will look at both options so that you can choose the most suitable for your situation.
Preparation of the device before complete reset
Before you start a cleaning mechanism, it is critical to perform a series of preparatory actions, ignoring this step can lead to the loss of valuable information or lock the device after rebooting.
Create a backup of contacts by syncing them with your Google account or saving them to a file on your Google account. SIM-map/SD-Photos and videos are best copied to a computer or uploaded to a cloud storage, as the internal memory will be completely cleaned. 50-60%, so that the process is not interrupted by the discharge.
⚠️ Note: If you have a Google account installed on your phone, be sure to remove it from your settings before resetting (Settings) → Otherwise, after the reboot, the system will require you to enter a password from this account (protection) FRP), Without it, it will be impossible to enter the phone.
It's also worth removing the microSD card if it's installed. MIUI They usually ask for formatting confirmation. SD-The card, the physical extraction, ensures that the files are kept on the media, and check if you know the pattern lock or the key. PIN-screen unlock code, as it may be required to confirm actions.
☑️ Checklist before reset
Method 1: Reset via MIUI settings
The easiest and most secure method is available if the smartphone interface is functioning normally and you can get into the main menu, which is convenient because the system controls the process of closing applications and cleaning the cache.
In the menu that opens, scroll down to About Phone, where you can find basic information about the model, Android and MIUI versions, and the memory management button. Click on it to go to the deep menu of system options.
At the bottom of the screen, you'll find the Reset button, and if you click on it, it'll offer two options: Reset all settings (return only system settings, save files) and Clear all data. We need a second option to fully return to factory status.
Once you select a cleanup point, the system will request confirmation of the action, warning you to delete all data, you will need to enter the unlock password of the screen, after confirmation, the preparation process will begin, which will take a few seconds, after which the device will restart and begin cleaning.

Before resetting through settings, take a picture of the screen with important Wi-Fi network settings or email settings to recover them faster after the reboot.
Method 2: Hard Reset with Recovery Mode
If the smartphone is stuck, doesn't turn on to the desktop, or the unlock password is forgotten, the reset method is used. It's a low-level menu that loads regardless of the main operating system. To log into Recovery Mode on Redmi 9C, you need to turn off the device completely.
When the screen goes out, press both the Volume Up and Power button at the same time, hold them until the Mi logo appears, and then the power button can be released, continuing to hold the volume until the Recovery menu appears.
This menu is controlled by volume buttons (up/down), and the choice is confirmed by the power button. You need to find the Wipe Data item and select it. Next, the system will suggest selecting Wipe All Data for complete cleaning.
⚠️ Attention: In Recovery mode, the touch screen is not working. All actions are performed exclusively by mechanical volume and power buttons.
Once Confirm is confirmed, the formatting process will begin, and unlike resetting through settings, there will be no unnecessary questions, the process will go automatically, and Data wiped successfully will appear on the screen when it is completed.
What happens if Recovery does not open?
Comparison of data dumping methods
Both of these methods lead to the same result, a clean system, but there are technical differences that can affect the choice in a particular situation, and understanding these nuances will help avoid mistakes.
The method through settings is softer, because the OS itself correctly closes the background processes. The method through Recovery is more aggressive and often required when software failures when the interface is not responding. Below is a comparison table.
| Parameter | Through Settings. | Through Recovery. |
|---|---|---|
| Availability | Only when the screen is running. | Even with a locked phone |
| Difficulty | Low (intuitive) | Medium (buttons needed) |
| Risk of error | Minimum | Medium (human factor) |
| Implementation time | 5-10 minutes | 5-10 minutes |
Choose a way through the settings if the phone is stable, saves time and nerves. Use Recovery only if necessary or if you are an experienced user who is used to this interface.
First start and setup after reset
Once the procedure is completed, the phone will automatically restart, take 3 to 5 minutes to run for the first time, and the Mi or Android logo can be displayed on the screen, which is the normal system reaction to a clean file structure.
A welcome screen will appear with a choice of language. Select Russian and press the start button. Then the system will ask you to connect to the Wi-Fi network. This is necessary to activate the device and check for security updates.
Signing in to a Google account is an important step: If you have previously deleted your account from settings (as recommended), simply enter your details. If the reset was done bypassing the standard deletion procedure, the system may require you to enter a password from the last synchronized Google account.
Once you log in to Google, data recovery will begin if you select the appropriate option, apps, contacts and settings will be downloaded from the cloud, and full synchronization of all applications can take up to an hour depending on the speed of the Internet and the number of programs installed.
Possible problems and solutions
Despite the simplicity of the procedure, there can be unforeseen complications, most often users are faced with FRP (Factory Reset Protection), a Google security mechanism that prevents the use of a stolen device.
If the phone requires an account you don't remember, it's going to be extremely difficult to restore access without a check to buy it. Another common problem is a bootloop. If the phone is constantly rebooting after a reset, the system partition may be damaged.
- 📱 Forgot your account password: try to restore access via a computer on Google or use another phone to reset your password.
- 🔄 Cyclical reboot: try logging in to Recovery again and resetting again. If it doesn't work, you need to flash it over your computer.
- 🔋 Phone does not turn on: put the device on charge 30-40 Even if the light is not on, then try to turn it on again.
In rare cases, the communication modules may not work after reset. SIM-If the problem persists, you may need to reset the network settings through an engineering menu or contact the service.
