Users often face the need to radically clean up their device from accumulated digital debris, viruses, or before selling a gadget. Full formatting of a Xiaomi smartphone is not just about deleting files, but a deep restructuring of the file system, returning the device to a factory state. Unlike simply removing applications, this procedure affects system partitions, which requires caution and understanding of processes.
Modern MIUI and HyperOS shells have multiple layers of protection and different reset methods that can confuse an inexperienced owner. Mistakes can lead to a device being locked by an account or losing important data without recovery, which is why it is important to follow the algorithm that is right for your situation and the state of the operating system.
In this guide, we’ll take a look at all the options available, from the standard settings menu to the Recovery Engineered Mode, and learn how to properly prepare your phone so that it’s as clean as a tear when turned on and ready for a new life or a quick sale to a new owner without further ado.
Preparation of the device for complete reset
Before you start the formatting process, you need to perform a number of critical actions, ignoring which can turn your phone into a brick or lead to loss of access to accounts. The first step should always be a backup. Copy contacts, photos, videos and documents to external media or to the cloud, as a complete reset will irrevocably delete all user data.
Special attention should be paid to the Mi Account and Google Account. If you do not log out before reset, FRP will work. Once formatted, the phone will require you to enter a password from the last synchronized account. If you do not remember it or remove the device from the trusted list in advance, unlocking the smartphone will be extremely difficult.
⚠️ Warning: Don’t forget to unplug your device from your Mi Account via settings or i.mi.com, otherwise your phone may lock after a reset, requiring a password from your old account.
Also make sure that the battery is at least 50-60%.The formatting process, especially if it affects system partitions, can take time, and a sudden power outage at this point will damage the bootloader or system files. Connect the device to a stable Wi-Fi network if you plan to use cloud-based backup features before cleaning.
☑️ Checklist before formatting
Method 1: Standard reset via system settings
The safest and most recommended method for most users who have access to the desktop and the phone menu, which minimizes the risk of software errors, as the operating system itself correctly completes all processes before cleaning. First, open the Settings app and scroll to the bottom of the list to About Phone.
In the menu that opens, find Reset. The system will offer two options: Reset (returns only system settings, leaving files) and Erase all data (full formatting). We need the second option. After clicking, the system will show a list of what will be deleted: photos, music, apps and accounts, this point of no return, after which data will not be restored by standard means.
To confirm the operation, you will need to enter a pattern lock, PIN-If the device has two-factor authorization or Mi Account confirmation enabled, you may need to enter your account password. Once confirmed, the phone will restart, the cleaning process will begin, which can take anywhere from 5 to 15 minutes depending on the amount of memory.

Method 2: Formatting with Recovery Mode
If the operating system is damaged, the phone hangs on the logo or does not boot to the desktop, Recovery mode is used. This is a low-level environment that allows you to control the device bypassing the main OS. To enter this mode, you need to completely turn off the smartphone, and then pinch the key combination: usually it is Volume Up + Power.
Hold the buttons until the Mi or Android logo appears, and then the phone goes to the Recovery menu. Navigation is done with volume buttons (up/down), and the choice is confirmed by the power button. In some models with touch Recovery, control is directly through the screen. You need to find the Wipe Data item or Erase data.
Then the system can offer two options: Wipe All Data (complete clean) and Keep User Data (save data, but reset settings). Choose a complete cleanup. After that, you will need confirmation, often you need to choose Confirm or Yes. The process will take some time, when completed, the phone will automatically restart to the clean system.
| Action. | Buttons (standard) | The result |
|---|---|---|
| Entrance to Recovery | Volume Up + Nutrition | Launch of the recovery regime |
| Navigation | Volume Up/down | Moving on the menu |
| Confirmation | Power button | Choice of menu item |
| Exit/Reset | Reboot (automatically) | Starting a clean system |
Using Fastboot for Deep Cleaning
Fastboot is primarily designed to flash the device through the computer, but it also allows you to execute commands to deep clean partitions.This method is more complex and requires a PC, an ADB/Fastboot driver installed, and a USB cable.It is useful when other methods don't work or require guaranteed removal of all partitions, including cache and temporary files.
To enter Fastboot mode on the phone turned off, press the Volume Down and Power buttons simultaneously. The screen will show an image of a rabbit repairing an android that says FASTBOOT. Connect the phone to your computer. Open the Command Prompt (CMD) or the terminal on your PC in the ADB tool folder.
Enter fastboot devices to make sure the computer sees the device. If the serial number is displayed, you can clean up. The fastboot erase userdata command will delete the user partition, and the fastboot erase cache will clear the cache. Be extremely careful: using the fastboot oem unlock command can unlock the bootloader, which will entail data cleansing and potential loss of warranty.
⚠️ Note: Commands in Fastboot are executed instantly and without additional confirmations on the phone screen. A command error (for example, erasing the system partition instead of the user partition) can make the device unusable.
Mi Account issues and FRP blocking
One of the most common problems after full formatting is requesting a Google account (FRP) or Mi Account. This is a security mechanism designed to make it harder to use stolen devices. If you drop your phone through Recovery or buttons without first deleting your accounts in the settings, the system will perceive this as potential theft.
When you first set up after resetting, the phone will require you to enter a password from a Google account that was previously synced, without this password you will not be able to log in. Similarly, Mi Cloud protection works: if Find Device was active, the phone will lock and require a password from Mi Account.
To avoid these problems, always manually delete your account before resetting. Go to Settings → Accounts and Sync, select your account and click Delete Account. Only after the account has disappeared from the list can you safely format your device in any way.
💡
Tip: If you sell a phone, make a reset with a customer, which will prove that the device is not locked into other people's accounts and has no hidden locks.
What to do if the phone is not reset
In rare cases, the formatting process can be interrupted or frozen. If the phone is stuck on the Mi or Android logo for more than 15-20 minutes, the system partition may be damaged or data recording interrupted. In this situation, try to perform a forced reboot by holding the Power button for 10-15 seconds.
If the device is in a bootloop cycle, you will need to flash it through your computer using the Mi Flash Tool or Xiaomi ADB/Fastboot Tools utility. Full formatting through the menu in this case will not help, since the operating system itself is damaged. You need to download the official firmware for your model and restore system files.
Also, the reason for the inability to reset can be a mechanical malfunction of the buttons or problems with the memory of NAND. If none of the software methods helps, and the phone behaves inadequately, it is likely that intervention in the service center for the diagnosis of the hardware is required.
💡
If a standard reset doesn’t help or causes a cyclical reboot, the only solution is to completely flash the device through your computer using official Xiaomi tools.
