This is a drastic but often necessary step to fix software errors, remove hidden viruses, or prepare the gadget for sale to a new owner.

The most important task is to preserve personal data, since after pressing the recovery confirmation button, all photos, contacts, messages and files will be permanently deleted from the internal memory.
Use cloud services or a computer to create a backup copy. For ecosystem owners Xiaomi the most convenient way is synchronization via Mi Cloud, which automatically saves contacts, notes, voice recordings and a calendar. However, media files such as photos and videos often take up too much space in the cloud, so it is better to copy them to your PC via a USB cable or upload them to services like Google Photos.
⚠️ Attention: Make sure the battery level is at least 50-60%. If the phone turns off while formatting the memory partitions, this may damage system files and make the device unable to boot.
You also need to unlink your account Googleif you plan to sell the phone or transfer it to another person. In modern versions Android there is protection FRP (Factory Reset Protection)that requires entering the password from the last synchronized account after the reset. If you forget this data, the phone will remain locked, and unlocking will require complex procedures through the service center.

To begin, open the “Settings” application and scroll down the list to the “About phone” section. This is where the main system management tools are hidden. You will need to find the “Reset settings” option, which is usually located at the very bottom of the list of device settings. By clicking on it, you will see several recovery options, among which we are interested in “Delete all data.”
The system will warn you that all files will be deleted and ask you to confirm the action by entering your screen unlock password or PIN code.

What to do if the phone is not included in Recovery?
If the button combination does not work, try connecting the switched off phone to the computer via a USB cable, and then hold down the buttons. Sometimes entering recovery mode is only possible if there is external power or a connection to the PC.
Deleting a Google account and protecting FRP
One of the most serious problems that users face after a reset is activation lock FRP (Factory Reset Protection). This security feature was introduced by the company Google to protect devices from theft. The gist of it is that after performing a Hard Reset, the phone, when setting up for the first time, will require you to enter the password for the account Googlethat was synchronized with the device before the reset.
If you reset the phone for yourself and remember the login details, there will be no problems. However, if you buy a used device or forget the password, the phone will turn into a useless piece of plastic. It is almost impossible to bypass this protection in legal ways without account data, since this requires flashing the device using special equipment.
To avoid this situation, be sure to delete the account manually before performing a reset through the settings. Go to the Settings → Accounts and synchronization → Googlesection, select your email address and click “Delete account”. After this, the system will no longer associate this device with your profile, and FRP protection is not activated after cleaning.
- 🔐 FRP protection is triggered only when reset via the Recovery buttons.
- 🗑️ When resetting through the settings menu by entering the screen password, FRP is usually not required.
- 📧 Always delete your Google account before selling your phone.
Owners Redmi Note 9 should also consider linking to Mi Account. Although this protection is less strict than Google, having someone else's Xiaomi account may limit the ability to use some functions, such as finding a device or cloud storage.
The most reliable way to avoid an FRP lock is to manually sign out of your Google account in your phone settings before performing a data reset.
Solving problems after a factory reset
After After the procedure is completed and the phone has booted, users may encounter a number of questions and features of the system’s behavior. Firstly, the first boot after a reset always takes longer than usual. This is due to the fact that the system needs to optimize applications and prepare the file structure for work, so you should be patient and do not try to force a restart of the device.
Secondly, you will notice that the phone runs much faster and smoother. This is a natural result of removing accumulated software garbage, cache and background processes that could slow down work MIUI. However, in the first days the battery may discharge faster than usual, as the system is busy indexing files and background data synchronization.
If after the reset some functions do not work correctly, for example, mobile data or Bluetooth does not work, check for system updates. Manufacturers often release patches that correct errors, and installing the latest firmware version can resolve residual software conflicts.
⚠️ Attention: Do not install all applications from a backup copy at once. Try working with a “clean” phone for a couple of days to make sure the system is stable, and install apps gradually.
It’s also worth checking the date and time settings, especially if you changed the time zone or traveled. Incorrect time can cause errors when connecting to Google servers and the operation of security certificates in the browser.
