Your Xiaomi, Redmi or Poco screen suddenly went out, and then it showed an image of a hare repairing an android that says "Fastboot"? Don't panic. This is a situation familiar to many owners of Chinese brand equipment. Fastboot mode is a low-level interface designed to flash the device, but its accidental launch can scare an untrained user. Most often the problem is solved in a few seconds, but there are more complex scenarios.
In this article, we will take a look at all the possible causes of the bootloader logo and provide step-by-step instructions for exiting it. You will learn how to use physical buttons, software methods through ADB and what to do if the device is stuck dead, the main thing is not to rush into radical measures like resetting to factory settings until safe methods have been tried.
Before we get into action, we need to understand the nature of the state that has arisen. Fastboot is not a system error in the usual sense, but a special mode of operation of the Qualcomm or MediaTek processor, which allows you to interact with the phoneโs memory directly from the computer, its activation may occur due to accidental pressing of buttons in your pocket, a failure when you update the system or even due to a key failure.
Causes of Accidental Loader Loader Mode Entry
Understanding the cause helps prevent a repeat of the situation in the future, and users often accidentally activate this mode without knowing the function of the buttons, but there are software failures that require attention.
The most common cause is mechanical stress, and if the phone was in a tightly packed pocket or bag, a long-term downward pressure of the volume button along with the power button could trigger a Fastboot entry, and sticky buttons or moisture into the control key area can also cause it.
Another common scenario involves software errors: a failure to install MIUI or HyperOS updates, an interrupted firmware or an attempt to obtain root rights can leave the device in this state, sometimes culprits are conflicting applications or corrupted system files that prevent the operating system from booting correctly.
- ๐ฐ Accidental pressing of the key combination "Loudness downยป + ยซFood" in your pocket.
- ๐ Software failure after failed firmware update OTA.
- ๐พ Installation of custom recavery or modified loader.
- ๐ Critical battery discharge at the time of the device switching on.
โ ๏ธ Note: If the phone is self-loaded and endlessly rebooted into Fastboot mode, this may indicate a physical malfunction of the volume button (closing contacts) or serious damage to the system partition memory.
Method 1: Standard button exit (Without data loss)
This is the first and most secure method, which works 90 percent of the time, and it doesn't require a computer connection, it doesn't delete your photos or your contacts, and it's basically about rebooting your device.
To do this, you need to find the power button. On modern Xiaomi models, it's usually on the right side of the body. Hold it and hold it. Don't let go of the button even if the screen goes out, which is a normal reaction.
Hold the power button until the Mi or Redmi logo appears on the screen again. This process usually takes 10 to 20 seconds. Once you see the brand logo, immediately release the button. The device should start as normal.
โ๏ธ Exit algorithm with buttons
If standard retention didn't work, try the combination: Hold the Volume Up and Power buttons simultaneously. Hold them for about 15 seconds. This combination works like an emergency restart on some models, ignoring the current state of the bootloader.

If the phone is in the case, it is better to remove it before trying to exit the Fastboot. the case can interfere with tight pressing of the buttons or create additional pressure on the keys, provoking re-entry into mode.
Method 2: Exit through ADB (If buttons don't respond)
In situations where physical buttons donโt work or the screen doesnโt respond to touch, USB debugging comes to the rescue. This method requires a computer (Windows, macOS or Linux) and an ADB driver (Android Debug Bridge) installed.
First of all, make sure your PC has drivers for Xiaomi installed.Plug your phone to your computer via original or quality. USB-If the debugging mode is on the cable USB If you've activated it before, the computer recognizes the device (CMD) or terminal in a folder with ADB.
Enter the following command to check the connection:
adb devicesIf your device's serial number is displayed in the list, the connection is established. To exit bootloader mode, type in the command:
adb rebootThis command compulsorily sends a signal to reboot, and the device should blink the screen and start the standard on-line procedure. If the adb reboot command fails, you can try a more specific command to exit the fastboot:
fastboot reboot๐ก
Using ADB is the most reliable software method, as it sends a direct signal to the processor, ignoring possible locks at the button level.
Method 3: Battery discharge (Radical method)
When software methods are not available and buttons don't respond, the last "hardware" method is left, and it's based on the complete depletion of battery power, and it's data-safe, but it takes time.
Leave the phone alone. Because the screen in Fastboot mode is constantly on (or the phone vibrates), the battery will consume a charge. Depending on the battery capacity and battery condition, this can take anywhere from a few hours to a day.
Once the charge drops to a critical level, the device will turn off itself. Then plug in the original charger. In most cases, the phone will immediately start charging, and when you try to turn on (or automatically) will start the operating system, bypassing the bootloader mode.
- โณ The method takes a long time (from 4 to 24 hours).
- ๐ Guaranteedly turns off the device, even if it is getting stuck dead.
- ๐ Not suitable if the phone is connected to a charger or power bank.
- ๐ After switching on, you may need to re-set the time and date.
โ ๏ธ Warning: Do not leave a discharged lithium polymer battery in a deep discharge state for weeks. Prolonged storage in a completely discharged state can lead to irreversible battery degradation and bloating.
Diagnostics of problems with buttons and iron
If the phone is constantly returning to Fastboot mode immediately after leaving it, the problem is likely hardware-related, and in 95% of these cases, the Volume Down button is to blame.
The mechanism of the button could get dirty, oxidized or just physically worn out, which causes the contacts to close constantly. For the system, it looks like you are holding your finger on the button, which causes a cyclic entry into the bootloader every time you turn on.
For initial diagnosis, you can gently (without fanaticism) tap your finger on the volume button area or slightly crease the body in this area. If the phone reacts with a change in the state of the screen, then there is a problem in the contact. It is also worth checking whether the button falls visually.
| Symptoms. | Probable cause | Decision |
|---|---|---|
| The phone itself is included in the Fastboot | Volume button sticking | Cleaning or replacing the button |
| Cyclical reboot | Failure of firmware or battery | Flashing or replacing the ABC |
| Recovery Menu is not working | Damaged section recovery | Recovery through MiFlash |
| The computer can't see the phone. | Faulty. USB-port | Replacement of cable/port |

Firmware via Mi Flash Tool (If nothing helps)
If you canโt exit Fastboot mode because of a damaged operating system, youโll need a complete firmware reflash, which is an extreme measure that typically involves completely removing all data from the device.
To do this, you will need the Mi Flash Tool utility and the official firmware for your model in.tgz format (Fastboot). Download the firmware from the official website, unpack the archive and run the program on behalf of the administrator.
Connect your phone in Fastboot mode to your PC. In the utility, click the Refresh button, select the path to the firmware folder, and press Flash. The process can take 5-10 minutes. Once completed, the device will automatically restart with a clean system.
It is important to choose the correct firmware mode in the Mi Flash Tool. Clean all erases data completely, and clean all and lock also blocks the bootloader.Save user data mode tries to save files, but it works unstable when serious crashes occur.
โ ๏ธ Warning: Make sure to back up important data before you run the firmware if you can access files.Clean All permanently deletes photos, contacts and apps.

Flashing is โheavy artillery,โ and use it only when simple reboot techniques donโt work and youโre ready to lose data to restore your smartphone to work.
Prevention and useful advice
To avoid a repeat of unpleasant situations, you should follow a few simple rules of operation Xiaomi. First of all, monitor the state of the control buttons. Regular cleaning of ports and keys from dust prolongs the life of the device.
Avoid critical battery discharge. Try to put your phone on charge when the charge level drops below 20%. Deep discharge negatively affects the power controller, which can lead to strange behaviors of the system when turned on.
It is also recommended to update the software in a timely manner, with MIUI and HyperOS developers regularly releasing patches that fix bugs that can cause cyclical reboots or freezes.
- ๐ก๏ธ Avoid installing applications from unknown sources.
- ๐งน Periodically clean the system cache through the Recovery menu.
- ๐ Use original cables and power supplies.
- ๐ฑ Do not drop the device and protect it from moisture.
Compliance with these guidelines minimizes the risk of software failures, but if the problem is hardware-based, no software method will help forever โ it will require the intervention of a specialist.
