You turned on your Xiaomi smartphone, and instead of the usual logo, you had a black background with the words Fastboot and a white rabbit in a hat-eared? Don't panic - it's not a brick, but a service mode that is used to firmware, unlock the bootloader or diagnose. However, if the phone is stuck in the Fastboot and does not respond to buttons, the problem requires intervention. In 80% of cases, it can be solved without visiting the service center, but it is important to act on an algorithm to avoid aggravating the situation.
Fastboot (not to be confused with Recovery!) is a low-level interface that is activated when holding the Volume Down + Power key while on. Sometimes the smartphone hits it spontaneously due to a firmware failure, module conflict or failed update. In this article, we will discuss all possible causes of freeze in Fastboot, and also give step-by-step instructions for exiting the mode - from a basic restart to flashing through the Mi Flash Tool.
Warning: If the screen says "This device is locked" or "Device is corrupted," it's a signal that the bootloader is locked or the system files are damaged, and in such cases, a simple reboot won't help, more radical measures will be needed, but everything in order.
1.Why Xiaomi is getting stuck in Fastboot: 5 main reasons
Fastboot mode itself is not a bug, it's a tool for developers and service engineers, and it's a problem when a smartphone gets stuck in it and can't boot the main system. Here are the most common reasons:
- π Interrupted Software Update: If power is turned off during the installation of firmware via Ota Updater or Mi Flash Tool, the network crashes or the user forcibly restarts the device, the system may remain in a βsuspendedβ state.
- π§ Custom firmware conflict: Installing informal builds (such as LineageOS or Pixel Experience) without unlocking the bootloader or with errors often leads to a download cycle in the Fastboot.
- π± Hardware failure: Power connector damage, battery failure, or motherboard problems (such as memory chip dump) can mimic software errors.
- π Lock bootloader. on new Xiaomi models (for example, Redmi Note 12 or POCO X5) The default bootloader is locked. Trying to flash the device without unlocking results in perpetual booting to Fastboot with the error This device is locked.
- π¦ Viral software or root malware: Some applications (such as fake βunlockersβ or modified Magisk modules) can damage system files by causing freezes.
Separately, we should mention the βfalse Fastbootβ β when the smartphone looks suspended on the outside, but in fact simply can not load the interface due to a damaged display or graphics driver. To rule out this option, connect the device to the computer and check if it is defined in Device Manager as Android Bootloader Interface.
β οΈ Note: If you installed firmware from a third-party developer (not from the official Xiaomi website) before hanging, do not attempt to βcureβ the device through the Mi Flash Tool with the clean all option. IMEI and serial number!
2. Easy ways to exit Fastboot without losing data
Before you resort to radical measures, try standard reboot methods. They work in 60% of cases and do not require a PC connection.
Method 1: Forced resetting
Hold the Power button for 20 to 30 seconds until the screen goes out. If that doesn't work, try the combination:
Volume up + Power (hold 10-15 seconds)On some models (such as the Redmi 9A or POCO M3), you may need to pin Volume Down + Power for 15 seconds, then immediately press Volume Up.
Method 2: Transition to Recovery Mode
If the forced reboot didnβt help, try entering Restore Mode:
- Turn off the phone (hold power until vibration).
- Press Volume Up + Power and hold until the Mi logo appears.
- From the Recovery menu, select Reboot β Reboot to System.
If the Recovery menu is in Chinese, use this navigation scheme:
- π First button - Reset.
- π Second, shutdown.
- π The third is Wipe Data β donβt click unless you want to reset your settings!

Method 3: Connecting to charging
The common reason for the Fastboot to freeze is a dead battery. If the charge level is below 5%, the system may not start. Connect the original cable and power supply (at least 18W) and wait 15-20 minutes. Then try to restart the phone.
β οΈ Note: Using unoriginal cables or low-current charges (such as from an old Nokia) can damage the power controller.If the phone heats up after charging, disconnect it immediately!
3. Advanced methods: working with PC
If the simple methods didnβt work, youβll need a computer with ADB/Fastboot drivers installed and Xiaomi utilities installed. Below are step-by-step instructions for Windows.
Method 1: Exit through Fastboot commands
This method works if the smartphone is defined in the system as Android Bootloader Interface.
- Download and install Platform Tools (includes fastboot and adb).
- Connect your phone to your PC with a cable (preferably original).
- Open the Command Prompt in the platform-tools folder and type:
fastboot devicesIf the device is detected (its serial number appears), do:
fastboot rebootIf the team doesnβt work, try:
fastboot continueMethod 2: Flashing with the Mi Flash Tool
If the previous method didn't work, you'll have to reinstall the firmware.
- Download the official firmware for your model from the Xiaomi Firmware website (choose the Fastboot version, not Recovery!).
- Unpack the archive in a folder without Cyrillic characters.
- Install the Mi Flash Tool.
- In the program, click Select, specify the path to the folder with the firmware, then Refresh (the device should appear).
- Select Clean All (Full Clean) or Clean All and Lock (if you want to lock the bootloader).
- Press Flash and wait until it is completed (10-15 minutes).
What to do if the Mi Flash Tool is in error?
| Mistake in Mi Flash | Reason. | Decision |
|---|---|---|
| couldn't load device | No drivers or USB conflict | Reinstall the driver, change the port |
| flash not done | Firmware file damaged | Download the firmware again, check the checksum |
| device is locked | bootloader locked | Unlocking with Mi Unlock Tool |
| invalid image format | Wrong firmware format | Download Fastboot, not Recovery |
4. Unlock the bootloader: when necessary
If the Fastboot screen says This device is locked, it means that the bootloader is locked, and you can't flash the device in the standard way. Xiaomi locks the bootloader on all new models to protect against unauthorized access.
- Create a Mi Account and link your phone to it (unless you have done so before).
- Download the Mi Unlock Tool.
- Log in to Fastboot on your phone and connect it to your PC.
- Run the Mi Unlock Tool, log in and follow the instructions.
The process can take up to 72 hours β Xiaomi deliberately delays unlocking to protect users from scammers. Once successfully unlocked, you can flash the device through the Mi Flash Tool.
1. Connect to another PC (preferably with Windows 10/11).
2. Use the Mi Account to which the phone was previously linked.
3.Repeat try after 24 hours β sometimes Xiaomi servers limit the number of requests.-->
5 Hardware problems: when without service can not do
If none of the software methods worked, the reason for the freeze in the Fastboot could be hardware.
- π The phone doesnβt charge or discharges quickly (a problem with the battery or power controller).
- π When you connect to a PC, clicks are heard or the device is identified as Unknown. USB-Device (damaged USB-Type C connector).
- π₯ The case is heated in the processor area even when switched off (chip dump or short circuit).
- π± The screen flickers or shows artifacts (problems with a plume or graphics accelerator).
In such cases, self-repair is fraught with final breakdown. Contact the Xiaomi service center or a checked repair center. The average cost of diagnosis is 500-1000 rubles, repair (for example, replacing the connector or soldering contacts) will cost 1500-4000 rubles.
β οΈ Warning: If the phone is in water or falling, don't try to turn it on! This can lead to a short circuit, which requires a complete disassembly, cleaning and drying at the service center.
6.How to avoid hanging out on Fastboot in the future
To minimize the risk of getting back into Fastboot, follow these guidelines:
- π² Update the firmware only through official channels (Settings) β The phone. β Updating the system).
- π Do not install custom firmware without unlocking the bootloader.
- π Use original chargers and cables.
- π οΈ Check your battery health regularly through the AccuBattery app.
- π₯ Before firmware, do a data backup via Settings β Additionally. β Backup and reset.
If you often experiment with firmware, keep on hand:
- π₯οΈ A laptop with the Mi Flash Tool installed and ADB.
- π USB-Type C cable with data support (not all powerbank cables are suitable!).
- π Instructions to unlock the bootloader for your model.

If your phone has been stuck in Fastboot after a failed update, never try to flash it through Recovery - this can lead to a loss of IMEI. Use only Fastboot mode and official firmware.
