Modern Xiaomi and Redmi smartphones are powerful multimedia centers that can accumulate software errors, cache and unnecessary files that slow down the system. Often the only effective solution to restore performance or prepare a gadget for sale is a complete data reset, or formatting. This procedure returns the device to factory parameters, removing all user files and settings.
The formatting process can be required in a variety of situations, from the banal sale of the device to combat serious virus attacks or malfunctions in the MIUI and HyperOS operating system. It is important to understand that there are different ways to perform this operation, each of which has its own nuances and applications. The choice of the right method depends on whether the device has access to the menu or is blocked.
Before we take action, we need to recognize the critical importance of backup, because a complete reset permanently destroys all the information stored in internal memory, including photos, contacts, messaging, and installed applications, and ignoring this step can lead to the loss of valuable data that cannot be recovered by standard means.
Preparing the device for a complete data reset
The process should start with careful preparation that minimizes risks and ensures successful completion of the operation, the first step is to create a full backup of all important data. In the Xiaomi ecosystem, it is most convenient to use the Mi Cloud cloud service or third-party solutions like Google Drive. USB-cable, which is the most reliable method for large amounts of information.
The second critical point is the Mi Account, which is that if you log in to a Xiaomi account, the security system activates the theft protection, and once formatted, the device will require you to enter the username and password from which it was previously synced, and if you forget that data, the phone will turn into a brick, and it will be extremely difficult to unlock it.
⚠️ Warning: Before reset, be sure to log out of your Google and Mi Account manually through settings to avoid blocking activation after reboot.
The third aspect of preparation is to ensure stable power supply: the process of formatting and reinstalling system files is energy intensive. If the battery runs out at the time of writing system partitions, this can damage the bootloader, charge the device to a minimum of 60-70% or leave it connected to the original charger during the procedure.
It is also worth checking the presence SIM-MicroSD cards and memory cards: If you plan to format your phone for sale, it is better to remove the memory card so as not to give your personal files to the buyer. If the card remains in the phone, the system may offer to format it as part of internal memory, so be careful when choosing options.
- 📸 Backup photos and videos to the cloud or PC.
- 🔑 Remember or write down passwords from your Google and Mi accounts.
- 🔋 Charge the battery of the device above 60%.
- 💾 Remove the memory card or make sure it is not affected.
☑️ Preparation for formatting
Formatting through the Android settings menu
The easiest and safest way to get Xiaomi’s phone back to factory status is to use a built-in settings menu, which is suitable for most users whose devices are stable and have access to the desktop, it doesn’t require special knowledge or a computer connection, and the interface is as intuitive and intuitive as possible.
To start, open the Settings app and scroll down to the About Phone section. In some versions of the MIUI shell, the option you want may be in Advanced Settings. Look for "Reset" or "Factory Reset" and the system will alert you that all data will be deleted and suggest you choose whether to also clear your internal memory.
It's important to distinguish between two types of resets on this menu. The first option, Reset All Settings, will only return system settings (sound, screen, network) to the original settings, but save your files. The second option, Clear Everything, will format the device completely.
Why does the phone ask for a password when resetting?
Once confirmed, the phone will restart and start the cleaning process, which can take 5 to 15 minutes depending on the amount of information stored and the speed of internal memory, during which time the Xiaomi logo or animation of the Android robot can be displayed on the screen.
💡
Resetting through settings is the most gentle method that correctly closes all processes before deleting data, reducing the risk of program errors.
Reset to factory settings via Recovery Mode
If the operating system is damaged, the phone freezes on the logo or does not respond to touch, a standard reset through the menu is impossible. In such cases, a recovery mode known as Recovery Mode is used. This is a special diagnostic mode built into the device's memory regardless of the state of the main OS.
To enter this mode, you need to turn off your smartphone completely. Then press the volume button and the power button at the same time. Hold them until the vibration and the Mi logo appear, after which the power button can be released, continuing to hold the volume button. In a few seconds, the Recovery menu will appear with black background and text (often in English or Chinese).
Navigation in this menu is done with volume buttons (up/down), and the choice is confirmed by the power button. You need to find Wipe Data or Clear Data. In new versions of MIUI, you may need to enter a digital code displayed on the screen to confirm access rights. This is additional protection against unauthorized 1-ion reset.
Once you have selected the cleaning option, the system will request confirmation again. Select Wipe All Data or Confirm. The formatting process will start immediately. Upon completion, you will see the message "Data wiped successfully." After that, select Reboot to restart the system. The first start after such a reset can last longer than usual.
- 🔘 Turn off your phone completely before entering recovery mode.
- 🎚️ Use volume buttons to navigate the Recovery menu.
- 🔢 Be prepared to enter a confirmation code if it appears on the screen.
- ⏳ Wait for the process to be completed before restarting.
Use of PC and Mi Flash Tool
For advanced users or in cases of deep software failure, there is a method of formatting through a computer using the official Mi Flash Tool utility. This method allows not only to clean the data, but also to completely reinstall the firmware, which guarantees the removal of any, even the most hidden viruses or errors of system files.
To work, you'll need to download the Mi Flash utility from the official website, as well as the Fastboot ROM for your phone model. The firmware has a.tgz extension and must be unpacked on your computer. It's important that the firmware version is regionally appropriate or global if you're planning to change region.
Requirements for firmware through Fastboot:
1. Installed ADB and Fastboot drivers.
2. original quality USB cable.
3 Unlocked bootloader (Bootloader) for some operations.
4. Battery charge of at least 50%.The process is this: the phone is put into Fastboot mode (clamping the volume and power button when the screen is off), then the device connects to the PC, Mi Flash selects a path to the firmware folder and presses the Flash button, which completely erases all memory partitions, including the system partitions, and writes them back.
⚠️ Note: Using the Mi Flash Tool with incorrect firmware or interrupting the process can cause the device to fail completely (hard brick.
Features of formatting with a forgotten password
The situation when the user forgets the pattern lock or unlock password is one of the most common reasons for resorting to the reset procedure. Unfortunately, modern versions of Android and MIUI shells have a high level of protection that does not allow you to simply bypass the lock screen without losing data.
The only way to access a phone like this is by forced resetting through Recovery Mode, which is described above, and services like Google's Find Device allow you to remotely erase data, but only if the phone has Internet and search enabled, and if the phone is offline, this method won't work until it's connected to the network.
There is a myth that codes or secret combinations exist to reset passwords without losing data. In reality, by encrypting user data on modern Xiaomi smartphones, without knowing the password or the owner's account, you can't restore access to files. Encryption is tied to credentials, and resetting the password is equivalent to destroying the encryption key.
What to do after formatting is completed
Once the formatting process is successfully completed, the phone will turn on as new, greeting you with a language selection screen, which is a sign of a clean system. The initial setup will take some time: you will need to connect to Wi-Fi, log into a Google account and, if necessary, into a Mi Account.
The system will offer to restore data from the backup. If you have created a backup before, you can return contacts, call history and installed application list, but photos and documents often have to be copied manually or wait for them to sync from the cloud if you choose this option.
An important step is to upgrade the system. Since you may have dropped the phone to the factory version, it may be an older version of Android or MIUI. Go to Settings → About Phone → Update the system and check for new versions. This will close security vulnerabilities and improve stability.

💡
After reset, don’t install all the apps at once, just put the necessary ones in and watch the phone work for a couple of days to identify the possible culprit.
