When a Xiaomi, Redmi or POCO smartphone screen suddenly lights up with a hare fixing an android, it can take anyone by surprise. This mode is called Fastboot, and it's designed to deep-debug the system, but is often activated accidentally due to button sticking or software glitches. The main thing to know at this point is not to panic, because your data is in most cases completely safe.
There are a number of ways to break out of this state, from a simple restart to the use of specialized software on your computer. In this article, we will examine all possible scenarios in detail, including cases where the device is βhangβ and does not respond to standard commands. You will learn how to safely bring the gadget back to life using only built-in system mechanisms or a minimum set of tools.
Understanding how the bootloader mode works will help you avoid future errors and respond to crashes more quickly.We will look at both software exit methods and hardware nuances that can cause an endless reboot cycle. If the phone moved to Fastboot after trying to flash or unlock the bootloader, recovery actions may differ from a standard reset.
Why the smartphone got into Fastboot mode
Before you start resuscitating your device, you need to understand the cause of the problem, and most often, the transition to Fastboot mode is due to a simple mechanical effect. If you carry your phone in a tight case or in a pocket with keys, the volume button may be accidentally pinched when the device is turned on, and the system regards this as a command to enter the engineering menu.
There are more serious software reasons, however: a failure to update the MIUI or HyperOS operating system can cause the phone to fail to load the main interface and remain in command standby mode, and can also be caused by corrupted system files after failing to install superuser applications or modify the system partition.
Sometimes the problem is the hardware, because oxidizing the contacts of the volume button, getting moisture inside the case, or a flowing plume can create a false circuit, and in such cases, the phone can reboot cyclically or return to Fastboot mode continuously even after a successful exit.
β οΈ Warning: If the phone spontaneously goes into the Fastboot without your actions, carefully examine the volume buttons. Sticking a mechanical button is the most common cause of the "endless hareΒ».
For an accurate diagnosis of the causes, you can use the following table, which compares the symptoms with the likely sources of the problem:
| Symptoms. | Probable cause | Difficulty of solution |
|---|---|---|
| Appeared after switching on with buttons | Accidental pressing (mechanics) | Low. |
| Cyclical reboot | Firmware failure or OS damage | Medium |
| Not responding to the exit buttons | Sticking a button or a controller failure | Tall. |
| Appeared after connecting to the PC | Error ADB command or drivers | Low. |
The easiest way: a combination of buttons
In the vast majority of cases, about 90 percent, you just have to do a forced reboot to get out of Fastboot mode on Xiaomi, which is data-safe and doesn't require a computer connection, and all you need is physical access to the device control buttons.
The algorithm is very simple: you need to press the Power button and hold it for a long time. Usually, the system ignores short pressing in this mode, so you need long exposure. Some models, especially older versions of Redmi, may require simultaneous pressing of the on and volume buttons.
Hold the buttons until the screen is completely turned off and you feel the vibration or see the Mi or Redmi logo.The process can take from 10 to 20 seconds.If after the logo appears, the phone goes back to Fastboot, then the problem is not solved, and other methods described below are required.
βοΈ Proper exit with buttons
It's important to understand that if the power button is damaged or not working, this method will not work, and then you will have to look for alternative ways, for example, to use the software on a PC. It's also worth noting that on some global versions of firmware, the button combination may differ, but Power retention remains the universal standard.
Use of PC and Mi Flash Tool
If the push-button method is powerless, a computer will come to the rescue, the official Mi Flash Tool utility or even standard commands. ADB They can send a signal to unlock the boot cycle. USB-cable (preferably original) and installed drivers for Xiaomi devices.
First, connect the phone in Fastboot mode to your computer. In Windows Device Manager, you should see a device called the Android Bootloader Interface. If the drivers are not installed, the computer may not recognize the phone correctly. Once you connect successfully, you can use the command line.
Open the Command Prompt (CMD) or PowerShell on behalf of the administrator. Go to the folder with platform tools installed (ADB). To exit the mode, just enter a simple command that will force the device to restart to normal mode.
fastboot rebootPress Enter. The phone must immediately react with vibration and start a normal boot. If the system detects a device error, check the cable or try another one. USB-port, preferably USB 2.0, as they are often more stable with debugging modes.
β οΈ Note: Do not use Flash or Clear All in the Mi Flash Tool if your goal is to simply log out of Fastboot.
Exit through ADB Teams
For more advanced users who have Android Debug Bridge (ADB) installed, there is another reliable method that works even when the standard fastboot reboot can be ignored due to software freezes.This method requires that the phone has previously been enabled debugging over USB, but in Fastboot mode, some commands can be passed without it if the bootloader is unlocked.
The idea is to send a special reboot signal, connect the device to the PC and type in the terminal command:
adb rebootIf ADB sees a device, it will reboot. However, most often in Fastboot mode, the ADB is not active, and you need to use fastboot. But here's the caveat: if the phone is stuck in a loop, sometimes a complete shutdown command helps, after which you can try to turn it on normally:
fastboot oem poweroffOnce you do this, the screen will go out. Then press the on button to start the phone as usual. If that doesn't work, you may have damaged the boot or recovery partition and need to flash it back.
What if your computer doesnβt see your phone in Fastboot?
What to do if the power button does not work
The worst thing is that the power button physically breaks, in which case the standard method of holding Power becomes impossible. Fortunately, Xiaomi has a built-in mechanism that allows you to control power programmatically if you have access to the Recovery menu.
Try entering Recovery Mode. To do this, on a device that is off (or in a Fastboot) press both the on button and the volume button (+). If you're lucky, you'll be taken to the Main Menu menu. There, using the volume buttons for navigation and the power button for selecting (or tapping on the screen if the touch is working), select Reboot and then Reboot to System.
If the touchscreen in Recovery mode is not working and the power button is broken, the output is one - connecting to the charger or computer. Some Xiaomi models, when connected to a PC when turned off, can automatically turn on. You can also wait for the battery to completely drain. When the phone turns off itself, connect it to charging without pressing the buttons - there is a chance that it will start in normal mode, not in the Fastboot.
In extreme cases, if the power button is physically closed (pressed inwards), the phone will return to the Fastboot indefinitely whenever you try to boot, in which case you need to disassemble the device and disconnect the button plume from the motherboard for diagnosis.

If the power button is running out, try tapping your finger gently (without fanaticism) on the button area or slightly pressing it from the side to unlock the mechanism before trying to reboot.
Software failures and flashing
When all methods are exhausted and the phone keeps coming back to the rabbit, it is a serious damage to system files, which could be due to interrupted updates, mod incompatibility or viral activity, in which case you need to restore the software part of the device.
This will require you to download the official firmware for your model from miui.com or xiaomirom.com. The firmware must be in Fastboot format (with the extension.tgz), not Recovery (.zip). The recovery process through the Mi Flash Tool with the Clean All option is guaranteed to eliminate software errors, but completely delete all user data.
Before starting the procedure, make sure that the battery is charged at least 50%. Interrupting the firmware process can turn the smartphone into a βbrickβ, which can only be restored in a service center using paid boxes. Follow the instructions on the program screen carefully and do not turn off the cable until the Success message appears.
| Type of firmware | Expansion | Data retention | Appointment |
|---|---|---|---|
| Recovery | .zip | Maybe. | Update via phone menu |
| Fastboot | .tgz | No (Clean All) | Full system recovery |
| Fastboot | .tgz | Yes (Save Data) | Flashing without loss of photos/contacts |
β οΈ Warning: When flashing, make sure the correct firmware region is selected (Global, EU, Installing Chinese firmware on the global version without unlocking the bootloader is impossible and will lead to an error.

If the phone goes into the Fastboot cyclically after all the reset attempts, the problem is most likely hardware - you need to replace the button plume or repair the motherboard.
