Modern Xiaomi smartphones based on the Android operating system have powerful functionality, but over time, even the most productive devices can experience slowdown. Accumulation of system debris, errors in updates or software failures often cause instability. In such situations, the most effective solution is a complete memory cleanup, known as formatting or resetting to factory settings. This procedure returns the gadget to its original state, eliminating software errors and removing unnecessary files.
The formatting process is necessary not only when selling a device, but also before installing custom firmware or after removing malware. It is important to understand that this step is irreversible: all personal information, including contacts, photos and installed applications, will be irretrievably lost. That is why preparing for an operation requires careful approach and creating backups of important data. Ignoring this stage can lead to the loss of valuable information, which will subsequently be impossible to recover by standard methods.
In this guide, we will take a closer look at all the available ways to format Redmi, POCO and Xiaomi devices.We will look at the standard method through the settings menu that suits most users, as well as more complex options through Recovery Recovery Mode and Fastboot Engineering Mode.We will focus on security issues related to the Mi Account, the lock of which can be an unpleasant surprise for the new owner after a reset.
Preparing the device for a complete data reset
Before you start any manipulation of system files, you need to do a number of preparatory steps. This is a critical step that is often ignored, which leads to problems in the formatting process. Backup is the first thing to take care of. You can use Google Drive or Mi Cloud cloud services, as well as locally save data to your computer or external drive.
Make sure that the battery charge of the smartphone is at least 50-60%. Interrupting the reset process due to battery discharge can damage the system partitions and turn the device into a "brick". SIM-MicroSD card and memory card, if installed, will protect your data on the card from random formatting and prevent possible system conflicts during the procedure.
☑️ Checklist before reset
Special attention should be paid to the Mi Account. Find Device anti-theft feature tightly links the device to the owner's account. If you do not untie the device or do not know the password to log in, after resetting, the phone will request authorization of the previous owner, which will make it impossible to use. To disable, go to account settings and select the exit option.
⚠️ Note: If you plan to sell your phone, be sure to log out of all Google and Mi accounts. Otherwise, the new owner will not be able to activate the device due to security. FRP (Factory Reset Protection).
Check the availability of drivers and tools if you plan to use a computer. Fastboot mode may require special utilities such as the Mi Flash Tool or ADB. Although they are not needed for a standard reset, their presence on a PC can come in handy in case of unforeseen errors when booting the system.
Standard reset via the Android settings menu
The easiest and safest way to format a Xiaomi smartphone is to use the built-in feature in the settings menu, which is available if the operating system is booting and you have access to the interface, and is ideal for preparing the device for sale or fixing minor software glitches, which takes a few minutes and does not require a connection to the computer.
To start, open the Settings app and find the About Phone section. Depending on the version of the MIUI shell or HyperOS, the path may vary slightly. In older versions of the interface, the desired button is in Advanced Settings, and in newer versions, right in the device menu. Select Reset or Erase all data.
The system will alert you that all data will be deleted, and you will be asked to select additional options, such as cleaning internal memory, and after confirmation, the system may request the input of a pattern lock, PIN-The screen unlock code or password to verify the identity of the owner is an important security measure to prevent accidental or unsanctioned presupupuan reset.
Once you press the confirmation button, the cleaning process will begin. The phone can reboot several times, and the screen will display the progress bar. Do not touch the device at this time. Upon completion of the procedure, the smartphone will turn on as a new one, suggesting that you select the language and adjust the original settings. All user data will be completely destroyed by this time.
⚠️ Warning: During the reset process, the phone may get hot.This is a normal reaction of the processor to actively working with the file system, but make sure the device lies on a hard surface for better heat sink.
If there is a mistake or a process is stalled, don't panic. In most cases, just wait 10-15 minutes. If the progress is unchanged for more than an hour, you will need to force the reboot and try to use the method through Recovery Mode, which is described below.
Formatting with Recovery Mode
Recovery Mode is a special diagnostic interface built into Android firmware that allows you to perform system operations regardless of the state of the main operating system. This method is indispensable if the phone does not boot, freezes on the logo or does not respond to touch input.
To enter Recovery, turn the device off completely. Then simultaneously press the Volume Up and Power buttons. Hold them until the Mi or POCO logo appears, after which the power button can be released, continuing to hold the volume. In a few seconds, a menu with several items in English or Chinese will appear.
Navigation in this menu is done with volume buttons (up/down), and the option is selected with a power button. You need to find the Wipe Data or Clear Data bar. In some versions of Recovery, you first need to select Wipe All Data, and then confirm the action by selecting Confirm. The system can ask for confirmation several times, requiring you to select OK.
What to do if the menu is in Chinese?
Recovery formatting is faster than settings because it minimizes background processes. Once you finish cleaning, the Data wiped successfully message will appear on the screen. Select Back to Main Menu and then Reboot -> Reboot to System. The first download after such a reset can last up to 5-10 minutes.
Importantly, this method also deletes all data, but does not always affect internal memory as deeply as full flashing.However, for password reset or device sales purposes, this is quite enough.
⚠️ Attention: In Recovery mode, the touch screen is not working. All actions are performed only with mechanical buttons. Be careful when selecting items so that you do not erase the wrong partition.
Using Fastboot Mode for Deep Cleaning
Fastboot is designed for developers and advanced users, and it allows you to interact with the bootloader at a low level, and through this interface, you can not only reset the settings, but also completely reflash the phone, replacing the system partitions, this is "heavy artillery", when other methods do not help or require a change of the firmware region.
To enter Fastboot mode, turn off your phone and press the Volume Down and Power buttons simultaneously. Hold them until an image of a hare repairing an android appears, with the caption: FASTBOOT. In this state, the phone is ready to connect to the computer through USB-You'll need drivers installed to work. ADB/Fastboot Mi Flash Tool or Command Prompt.
Once you connect your device to your PC, run the command prompt (CMD) on behalf of the administrator. Enter the command fastboot devices to check the connection. If the device is identified, you will see its serial number. To perform the data reset, the command fastboot erase userdata is used. This command forcibly clears the partition with user data.

fastboot rebootUsing Fastboot gives you deeper access to the file system than a standard reset, but it comes with risks: the wrong command can damage the bootloader or other critical partitions. Therefore, this method is recommended only for advanced users who understand the structure of the Android partitions.
Once the commands are executed, the phone will restart. If partitions are logically damaged, this cleaning often helps restore normal boot. In the event that the standard Recovery mode does not start, Fastboot remains the only way to bring the device back to life without going to the service center.
Deletion of Mi Account and Protection against Blocking
One of the most important procedures in Xiaomi formatting is managing the Mi Account. The company's security system is closely integrated with cloud services. If Find Device was active, the device is locked by linking to the account. Once the settings are reset, the phone will require you to enter a password from the account that was on it before formatting.
To avoid problems, make sure to do the following before reset: Go to Settings -> Mi Account. Click on the Log Out or Delete Acca button. The system will require you to enter a password for confirmation. Only after successfully logging out can you start formatting, which ensures that the new owner can activate the phone.
If you forget your account password, restore it through i.mi.com before resetting. Attempts to bypass this protection by software methods often result in a device lock at the server level. FRP lock (Factory Reset Protection) is a mechanism for protection against theft, which can not be simply disabled without authorization data.
| Action. | The risk of blocking | Required data |
|---|---|---|
| Reset via Settings | High (if not out) | Screen password, Mi Account |
| Reset via Recovery | High (if not out) | Password Mi Account when activated |
| Reset via Fastboot | Medium (depending on version) | Mi Account password, unlocking BL |
If you buy a used device, make sure to check if the previous owner is out of all accounts. If the first setup of the phone asks you to enter a password from someone else's Mi Account or Google Account, this means that the reset was performed incorrectly. You can only return such a device through the seller who provided the gadget.
Possible mistakes and ways to solve them
The formatting process doesn't always go smoothly. Users can experience a variety of errors, from stuck on the logo to not being able to reset. One of the common problems is the bootloop cycle. If the phone is endlessly rebooted after trying to reset, the system partition may be damaged or the update interrupted.
In this situation, re-entering Recovery mode and trying to run Wipe All Data again will help. If this does not help, you will need to flash the device through the Mi Flash Tool in Fastboot mode. You need to download the official firmware for your model and follow the recovery instructions. Unlock the bootloader may be required for full flashing, which takes up to 7 days of waiting.
Another common error is the message "Failure to reset" or "Formatting error." This often happens if the internal memory is physically worn out or the file system is damaged. In rare cases, formatting via ADB from a computer solves the problem using the adb reboot recovery command to force the transition to recovery mode.
💡
If the phone goes into a cyclic reboot after reset, try pressing the Volume Down + Power button for 10-15 seconds for a forced reboot, then log back into Recovery and re-clean.
If standard methods don't work, it may indicate a more serious problem that requires specialist intervention, but 90 percent of the time, repeating the procedure with all the preparation steps and a stable battery charge solves the problem.
⚠️ Warning: Do not attempt to interrupt the formatting process by removing the battery (if it is not removable) or disabling the cable.This is guaranteed to damage the file system and require complex recovery through the service center.
💡
Properly preparing and logging out of Mi/Google accounts before resetting eliminates 99% of the device lock issues after formatting.
