Before you take any drastic action, you need to complete a number of preparatory steps that will secure your data and ensure the stability of the process. Backup is the most important step, ignoring which can lead to the irretrievable loss of photos, contacts and correspondence. The built-in MIUI tools allow you to quickly create a backup to a memory card or to the cloud storage, which will take only a few minutes of your time.
It is also critical to check the battery charge level.The process of formatting and reinstalling system files is energy intensive, and a sudden power outage in the middle of the operation can disrupt the structure of the memory partitions.Make sure the device is at least 60-70% charge, and ideally connect it to the charger throughout the cleaning procedure.
⚠️ Attention: Deleting your Google and Mi Account before resetting is a must for modern versions of Android.If you just perform a reset without leaving your accounts, the security system is a must-have for modern versions of Android. FRP (Factory Reset Protection will lock the device the next time it is turned on, requiring a password from the old owner.
Don't forget to remove the memory card. SD and SIM-Although modern systems rarely affect external drives in a standard reset, physical extraction ensures that your media files on the flash drive remain intact. Also, it will prevent important documents from being accidentally deleted if you mistakenly choose the entire storage format option.
☑️ Redmi 7 Preparation for Reset
Method 1: Reset via the system settings menu
The most secure and recommended cleaning method for most users Xiaomi Redmi 7 is done directly through the interface of the operating system. This method is convenient because all actions are performed in the usual graphics shell, and the system itself controls the integrity of the process. To begin, open the Settings app and scroll down to the bottom of the “About Phone” section.
In the menu that opens, you'll need to find "Reset" and the system will alert you that all data will be deleted. Here, you need to select the "Erase all data" option, which initiates full formatting of the internal drive. If you just reset the settings without choosing to erase the data, your files will stay in place, which will not solve the cleanup problem.
In some versions of the firmware MIUI You may need to enter a pattern lock, PIN-This is an additional security measure to prevent the device from being accidentally or maliciously reset by unauthorized persons. Once confirmed, the deletion process will begin, which can take 5 to 15 minutes depending on the amount of memory filled.
Once the procedure is complete, the phone will automatically restart, and the initial launch will last longer than usual, as the system needs to recreate the file structure and verify the integrity of the system partitions, and do not interrupt this process and wait for the welcome screen with the choice of language to appear.
Method 2: Hard Reset with Recovery Mode
If the operating system is unstable, freezes or does not start at all, the only option is to use Recovery Mode Recovery Mode. This method allows you to perform Hard Reset at a deeper level, bypassing the Android interface. To enter this mode on Redmi 7, you need to completely turn off the device, and then press the volume button and the power button simultaneously.
Hold the buttons until the Mi logo appears, then release the power button, but keep holding the volume button. When a menu with a black background and several lines of text (Main Menu) appears on the screen, you can release the second button. Navigation in this menu is done with volume buttons (up/down), and the choice of item is made by a short press of the power button.
You need to find and select Wipe Data, then confirm the action with Wipe All Data. The system will again warn you of irreversibility. Once confirmed, the cleanup process will begin, the progress of which will be displayed as a percentage. Once completed, select Back to Main Menu and then Reboot -> Reboot to System.

Method 3: Remote cleaning through Google
There are situations where physical access to buttons or smartphone screens is limited, but the device is connected to the Internet. In such cases, Google's Find Device service comes to the rescue, which is especially relevant if the phone is lost or stolen, and your priority is to destroy personal information, rather than keep the device running.
To use this method, you will need any other gadget with Internet access. Go to android.com/find and log in to the same Google account that was used on Redmi 7. If the device is online, you will see its location and the list of commands available.
Select the option "Clean the device" and after receiving the command, the smartphone will automatically reset to factory settings and delete all user data. It is important to understand that after this procedure, you will no longer be able to track the location of the phone, since communication with Google servers will be severed.
This method works only if the device is geolocated and has an active connection to the network (Wi-Fi or mobile Internet). If the phone is in aeromode or discharged, the command will be executed automatically at the time of the first connection to the network.
Features of cleaning Redmi 7 with unlocked bootloader
Xiaomi owners often encounter the concept of an unlocked bootloader, especially if the device has previously undergone modifications or flashing.The presence of an unlocked bootloader can affect the reset process, as standard data protection methods may work differently. In some cases, a warning may appear when a cleaned phone with an unlocked bootloader is turned on that the device is not secure.
If you are planning to sell a phone with an unlocked bootloader, a potential buyer may face restrictions in some banking applications or services that require a high degree of security, in this situation, it is recommended to think about returning the bootloader to its original state (Lock), but only experienced users who understand the risks should do this.
The process of locking the bootloader also results in complete deletion of data, so additional reset may not be necessary. However, if you just run Wipe Data on a device with an open bootloader, all your files will be deleted, but the status of the bootloader will remain the same, an important nuance for those who care about the security of the transferred device.

What to do after cleaning your smartphone completely
Once the formatting process is complete and the phone has restarted, you will see a welcome screen with a choice of language, which means that the complete deletion procedure has been successful and the internal memory is now empty, at which point the device is no different from the new device just taken out of the box in the store.
If you've been cleaning your phone for yourself to fix system bugs, you can now start setting up your original setup: Choose a language, connect to a Wi-Fi network, and log in to your Google account. The system will offer to restore data from backups you may have created earlier, which will allow you to return contacts, call history, and installed app lists.
If you've been preparing a Redmi 7 for sale, no further setup is required. Just turn off the device so the new owner can start getting acquainted with the gadget from scratch. Remember to also clear the Bluetooth list of paired devices on your main phone by removing the device sold from there.
