☑️ Preparing Realme C21 for reset
Reset settings through the system menu
The simplest and safest method of returning to factory settings is carried out directly through the operating system interface. This method is suitable for cases when the smartphone turns on, the screen responds to touches, and you have access to the settings.
First, you need to open the main menu and find the settings section. The shell interface Realme UI may differ slightly depending on the firmware version, but the logic of the arrangement of elements remains the same. You will need to go to the section responsible for additional system parameters.
Find item Advanced settings or System settings. Inside this section, you should look for an option related to backup and reset. Usually it has a name Recovery and reset. By clicking on this item, you will see a button Reset data.
The system will warn you that all files will be deleted. You will be prompted to enter your digital password or pattern if you have one set on your lock screen. This is a security measure to prevent accidental or unauthorized reset of the device by unauthorized persons.
Before resetting through the menu, remove the SIM card and microSD memory card to avoid accidental formatting of external drives.
After confirming the action, the smartphone will reboot and begin the cleaning process. The screen may go dark and the device may vibrate or make sounds during operation. Do not interrupt this process and wait until the initial setup screen appears.
Resetting through the menu is the most gentle method, since the system correctly closes all applications and services before clearing the memory partitions.
Using Recovery mode for a full reset
If the smartphone does not turn on, is stuck on the logo, or you have forgotten the unlock password, the only way out is to use a special recovery mode Recovery Mode. This method works at a low level and does not require access to the desktop.
To enter recovery mode, you must completely turn off the device. Then you need to hold down the key combination: the power button and the volume down button. Hold them simultaneously until the logo appears Realme, then release the power button, but continue to hold the volume down.
In the menu that appears, navigation is carried out using the volume buttons, and the selection is confirmed with the power button. You need to select a language (usually English), and then go to Wipe Data. In some firmware versions, this item may be called Format Data.
| Action | Control buttons | Result |
|---|---|---|
| Menu item selection | Volume Up / Down | Move the cursor |
| Confirm selection | Power button | Start function |
| Enter password (if required) | Volume buttons (numbers) | Unlocking the mode |
| Exiting the mode | Selecting Reboot | Rebooting the system |
After selecting the cleaning option, the system may prompt you to enter a security code. This is done to ensure that an attacker who stole the phone cannot easily erase the data. Enter the code using the Volume buttons to navigate through the numbers and the Power button to confirm each number.
⚠️ Attention: In Recovery mode, the touch screen does not work. All actions are performed exclusively by mechanical buttons on the smartphone body.
What to do if the Recovery menu does not appear?
If the button combination does not work, try connecting the switched off phone to a charger or computer via a USB cable, and then try to log in again. Sometimes this helps to activate the recovery mode.
Solving problems with Google protection (FRP)
Modern smartphones are equipped with an FRP security system, which ties the device to the last used Google account. After resetting the settings, the phone will require you to enter the login and password for this account when setting it up for the first time.
This is effective protection against theft, but it can create problems if you have forgotten your login information or bought the phone second-hand. If you do not remember your password, try recovering it through a computer or other device before resetting.
If access to your account is impossible, the official solution is to contact the service center with documents confirming the purchase of the device (receipt, warranty card). Service employees will be able to remove the block in a legal way.
There are various workarounds offered on the Internet, but their use carries risks. Unprofessional intervention in the security system can lead to a complete blocking of the device or the installation of malware.
Reset features on different versions of Realme UI
Software Realme is regularly updated, and the interface may change. The model C21 can have different versions of the shell installed, from early versions based on Android 10 to more recent updates.
In earlier versions Realme UI 1.0 the reset item is often located deep in the settings menu. The path may look like Settings → Advanced settings → Backup and reset. Users sometimes confuse this section with clearing the cache of individual applications.
Newer versions of the interface have made it easier to access these functions. Searching through settings has become more efficient: simply enter the word “reset” or “reset” in the search bar at the top of the settings menu, and the system will immediately offer the desired item.
Regardless of the software version, the essence of the process remains the same: all user information is deleted, and system files are returned to their “out of the box” state. The differences concern only the visual design of the menu and the names of some sub-items.
⚠️ Attention: Interface and menu layout may vary depending on regional firmware version and specific security updates. Always focus on the meaning of the items, and not just their exact name.
If you cannot find the desired item in the menu, use the search function inside the settings - this will save time and eliminate navigation errors.
Actions after resetting the settings
After the formatting process is completed and the phone has rebooted, you will see the welcome screen. The device is now ready for initial setup. This stage is no different from turning on a new smartphone from the store.
You will need to select a language, connect to a Wi-Fi network and log into your Google account. It is at this stage that the backup copy is restored if you created one earlier. The system will offer to restore contacts, applications and settings from the cloud.
It is recommended not to install all applications at once. Let the system run in basic mode for a while to ensure stability after the reset. Then gradually install the necessary apps from Google Play.
Be sure to check for system updates. After the reset, the phone can work on the software version that was installed at the time the backup was created. Go to Settings → About device → Software update and install the latest version.
Data recovery may take some time depending on the amount of information and the speed of the Internet connection. Do not disconnect the phone from the network during this period to avoid interruption of the synchronization process.
After the reset, be sure to install all available system updates to eliminate vulnerabilities and improve the stability of the Realme C21.
