When Xiaomi’s smartphone stops responding to commands, restarts indefinitely, or cannot boot the operating system, radical measures are needed. A routine reset via the settings menu is not available in such cases, and the only working solution is to use the low-level Fastboot mode. This tool, originally developed by Google engineers for debugging Android, allows you to interact with the device directly, bypassing a damaged file system.
The process of restoring the functionality of the gadget through this interface requires carefulness and strict adherence to the algorithm of actions, since any wrong action can lead to complete data loss or software failure. Hard Reset through console commands is a powerful method that erases all user memory partitions and returns the device to the state “out of the box”.
In this article, we will discuss how to properly prepare your computer and smartphone, what tools you will need to execute the fastboot erase userdata command, and how to avoid typical errors. You will learn about the nuances of working with drivers, how to enter debugging mode and how to solve problems if the device is not determined by the system.
Preparation of equipment and software
Before you start any manipulation of system partitions, you need to make sure that your desktop is fully ready for the procedure.You will need a personal computer or laptop running Windows, Linux or macOS. USB-cable, preferably original, as cheap counterparts often do not provide the stable connection required to transmit commands in Fastboot mode.
You need to install a specialized toolkit on your computer, known as SDK Platform-Tools. This package contains adb and fastboot executable files, without which you can not interact with the phone bootloader. You can download the current version from the official Android developer website, which guarantees the absence of malicious code and compatibility with the latest versions of Xiaomi firmware.
⚠️ Warning: Make sure that the battery charge of the smartphone is at least 50-60%. Interrupting the process of erasing data due to battery discharge can damage the boot sector and turn the device into a “brick».
It is also worth checking in advance for drivers installed for Android devices. Windows often requires manual driver installation through Device Manager if the computer does not recognize the connected phone automatically. Linux and macOS are usually enough standard packages, but some distributions may require setting up access rights through udev rules.
Enter Fastboot mode on Xiaomi devices
To get into the desired mode, you need to perform a certain sequence of actions with the physical buttons of the device. First completely turn off the Xiaomi smartphone, waiting for the final screen quenching. Then simultaneously press the Volume Down and the power button.
Hold both buttons until you see the Fastboot logo and the characteristic rabbit in an orange cap repairing the android, and it's visual confirmation that the bootloader is activated and ready to take commands from the outside. If you see the Mi logo and start booting, you've let go of the buttons in time or pinched them too hard, you need to repeat the procedure.
In some cases, especially on newer models with upgraded versions of MIUI or HyperOS, login can be blocked software if certain security conditions are not met. However, in most recovery scenarios, the button combination remains unchanged. If the device is connected to the PC in this mode, it should be identified in Device Manager as Android Bootloader Interface.
Setup of the command execution environment
After successfully connecting your smartphone to your computer in Fastboot mode, you need to open the command line or terminal in the folder with the Platform-Tools installed. In Windows, the easiest way to do this is by opening the tool folder, clamping the Shift key and right-clicking on the empty space, then selecting “Open PowerShell window here” or “Open in Terminal”.
The first step should always be to check the connection between the computer and the phone. Type in the command fastboot devices and press Enter. If you see a string of numbers and letters followed by the word fastboot, then the connection is correctly established and you can proceed to the next steps.

☑️ Pre-reset check
The process of data resetting through the console
When you're connected to the device, the most critical thing is to execute a user data erase command. The fastboot erase userdata team completely clears the partition where your photos, contacts, apps and settings are stored, which is the same as a factory reset, but it's done at a low level.
⚠️ Warning: This command permanently deletes all personal files. It will not be possible to recover data after this operation with standard means.
Enter the following command in the terminal and press Enter:
fastboot erase userdataThe process takes from a few seconds to a couple of minutes, depending on the amount of memory and speed. USB-The terminal will display a progress bar or a progress text message. Once completed, you should see the Finished. Total time: X.XXXs message.
To clean the system completely, it is also recommended to erase the cache partition that may have left the erroneous data that caused the problems. Use the fastboot erase cache command. This action is safe for user data, but helps to eliminate software conflicts left over from the previous one.
their failures.
Reboot and first start of the system
Once the userdata and cache partitions have been successfully cleaned, you need to initiate a device reboot in two ways: physically press the power button 10-15 seconds before vibration, or send a program command through the terminal.
The software method is preferred, as it guarantees the correct exit from the Fastboot mode.
fastboot rebootXiaomi's smartphone will reboot and the initial setup process will begin, as if you just bought the device in a store.The first launch after a reset can take longer than usual - from 5 to 10 minutes. This is normal, as the system reassembles the application caches and optimizes the file system.
💡
If the device is back in Fastboot after the reboot command, try running the command “fastboot oem reboot-bootloader” and then select the “Start” or “Recovery” option with the volume buttons.
During the first download, the system may request confirmation of a Google account or Mi Account that was synced to the device before the reset, which is FRP (Factory Reset Protection) protection mechanism, and you will need to enter the username and password that were previously used.
Table of the main commands Fastboot for Xiaomi
For ease of working with debugging mode, below is a table with the most useful commands that may be needed in the process of restoring or diagnosing a Xiaomi device.
| Team team. | Description of action | Risk of data loss |
|---|---|---|
| fastboot devices | Checking the device connection | No. |
| fastboot reboot | Reboot to normal mode | No. |
| fastboot erase userdata | Complete reset of user data | High (100%) |
| fastboot erase cache | Cleaning the system cache | No. |
| fastboot flash recovery img | Firmware of the recovery section | Medium (file required) |
Use of these commands requires caution, especially when using flash commands, which write new data to partitions of memory, an error in the name of the partition or image file can cause the device to fail. Always double-check the syntax before pressing Enter.
What to do if the team is not executed?
Solving common problems and errors
One of the most common problems is when your computer doesn't see your phone in Fastboot mode. Device Manager may display an unknown device. The solution lies in manually installing drivers. Download the universal Google USB Driver or Xiaomi-specific driver, select Update Driver -> Select from the list of available drivers -> Android Bootloader Interface.
Another common error is the message (bootloader) Permission denied, which means that the bootloader is blocked by the manufacturer. To perform the command to reset userdata on some models requires pre-unlocking through the official utility Mi Unlock Tool. Without this step, access to the memory partitions will be closed.
⚠️ Warning: Unlocking the bootloader officially allows data resets, but may result in loss of warranty and inability to use some security features such as Google Pay or Widevine keys L1.
If the phone continues to hang on the logo after all the actions, not only the data partition, but also the system partition may be damaged, in which case a simple reset is not enough – you will need a complete flashing of the device using the Mi Flash Tool utility and the official firmware in.tgz format.
