Selling a smartphone, transferring it to another user, or having to fix system bugs often requires the complete deletion of personal information. Owners of the popular Redmi Note 7 model should know that simply deleting files manually does not guarantee their disappearance, since data can be recovered with special utilities. A complete reset is the only reliable way to return the device to the “out of the box” state, clearing internal memory of contacts, photos and passwords.
The process of cleaning data on Xiaomi devices with a MIUI shell has its own features, which are important to consider so as not to lock the phone after rebooting. Before starting the procedure, you need to make sure that you have a battery charge and a Mi Account, since the security system can request authorization. In this article, we will discuss all the steps in detail so that you can safely prepare the gadget for a new life.
There are two main methods of doing this: through the standard settings menu and through Recovery mode. The first option is suitable for working devices, to the screen to which you have full access. The second method is hardware and is used in cases where the system is not loaded or locked by the lock screen (provided that you know the passwords).
Preparing the device for a complete data reset
Before you start the cleanup, it is critical to perform a series of preparatory actions, ignoring which can lead to the loss of important documents or lock the device. Backup is the first step that should not be missed, since after reset, it will be impossible to restore deleted files without a backup. Use cloud services or a computer to save contacts, correspondence in messengers and media files.
Special attention should be paid to accounts. Modern versions of MIUI have activated anti-theft protection, which links the device to a Google and Mi Account. If you do not log out before reset, the phone may require the previous owner to enter passwords on the next activation, which will be a serious problem for the new user.

Method 1: Reset via the MIUI settings menu
The safest and most understandable way to erase all data is to use the built-in functionality of the operating system, a method that is suitable for most users whose phones are stable and unlocked. First, open the Settings app on the home screen or in the notification curtain.
In the settings menu, you'll find the About phone section, which is usually at the bottom of the list. Inside this section, we're interested in Resetting.

The Importance of Deleting Google and Mi Accounts
Xiaomi’s modern smartphones are equipped with powerful anti-theft mechanisms. Google’s Find Device feature and a similar service from Mi Cloud tightly tie the device to the owner’s account. When you reset data through the settings menu, you usually automatically log out of accounts, but with Hard Reset, this connection can be stored on servers.
If, after resetting the phone on the first run, it requests a password from a Google account that was synced earlier, it means that the protection worked correctly. However, if you sell the phone, the new owner will not be able to activate it without your data, so manually logging out before resetting is a must.
To delete your Google account, go to Settings → Accounts and Sync → Google. Select your email address and click More (three dots) → Delete your account. Repeat the same procedure for your Mi Account in the Mi Account section.

What to do after resetting: the initial setting
Once the procedure is completed, the phone will restart and greet you with a language selection screen, as it was when you first turned on. If you plan to use the device yourself, you will have to go through the standard initial setup procedure, and the system will prompt you to connect to the Wi-Fi network for activation.
At this point, MIUI may request confirmation that you are the owner, especially if you have previously used Hard Reset. Enter your Google and Mi Account details if they have not been deleted in advance. If the phone is being prepared for sale, this stage must pass the new owner.
It is recommended not to install all applications at once. First, upgrade to the latest available version through the Settings → About menu to fix possible security vulnerabilities. Then gradually restore the data from the backup.
💡
The first 30 minutes after a reset, the phone may be slower than usual – this is normal, as the system indexes files and optimizes applications in the background.
Possible problems and solutions
Redmi Note 7 users may encounter various difficulties in resetting, one of the most common problems being hanging on the Mi logo after rebooting, which may indicate that system files are damaged or the upgrade process is interrupted before reset, in which case it may be necessary to flash the device through the computer.
Another common situation is the endless cycle of reboots. If the phone is constantly turned off and on, try logging into Recovery Mode and reset again. If this does not help, the problem may be of a hardware nature, such as wear and tear memory.
⚠️ Warning: Never interrupt the erasure process by removing the battery (if it is not removable) or clamping buttons.This can damage the bootloader and turn the phone into a brick".
If the touch screen or Wi-Fi is not working after the reset, check if you have custom firmware or modified Recovery (TWRP) installed. Official MIUI firmware rarely contains bugs affecting basic functionality after the reset.
