Imagine you turn on your Xiaomi, and instead of the usual MIUI logo, you have a black background that says FASTBOOT, a white rabbit in a hat, and a bunch of incomprehensible lines on the screen, and the phone doesn't load any further, doesn't respond to touch, and sometimes it doesn't even turn off the power button. Is it a virus, a breakage or a feature of the firmware? Spoiler: 90% of the time, the problem is solved without a service center.
Fastboot is not a bug, it's an engineering tool for low-level access to Android, and it's used to run the firmware, unlock the bootloader, or restore the smartphone. But why does the phone go into that mode? There are several reasons, from random button pressing to serious software failures. In this article, we'll take everything from diagnostics to step-by-step instructions for exiting fastboot, including cases where the smartphone "burst" after a failed update.
If you see a fastboot screen after a phone drop, moisture or an attempt to flash the device yourself, you can immediately go to the section "Hardware breakdowns." Otherwise, the problem is almost always software-based and solvable at home.
What is Fastboot Mode and Why You Need It
Fastboot is a protocol for interacting with the bootloader of an Android device via a computer, which, unlike normal mode, does not boot, and the user accesses the hardware at the command line level.
- π§ Developers - for debugging and testing firmware.
- π Users β to unlock the bootloader before installing custom firmware (e.g. LineageOS or Pixel Experience).
- π οΈ Service centers β to restore βbrickβ phones after unsuccessful updates.
- π System β sometimes the smartphone itself goes to fastboot in case of critical download errors.
On the fastboot screen you will see:
- Xiaomi logo with a rabbit in a hat (symbol of the regime).
- It's called FASTBOOT or FASTBOOT MODE.
- Device model information (e.g. MSM8953 for Redmi Note 4X)
- Product Name: [model].
- bootloader Unlocking Status: Device is LOCKED or UNLOCKED.
Important: the fastboot mode itself is not harmful to the phone, and the danger arises if you interrupt the process of firmware or unlocking - this can lead to a complete loss of the device's performance ("brick").
Why Xiaomi is loading itself in Fastboot: top-5 cause
If you havenβt pressed the button combination to log in to fastboot, but the phone still shows the rabbit, look for the reason in this list:
- Firmware failure: Most often occurs after an over-the-air (OTA) MIUI update or through the Mi Flash Tool. Causes: interrupted boot, incompatible firmware version, server errors Xiaomi.
- System malfunction: Viruses, left-handed applications with superuser rights, or manual removal of system files can disrupt the download chain.
- Hardware problems: Falling, getting moisture or wearing flash memory (eMMC) sometimes causes the phone to be unable to read the boot partition.
- Button swiping: If the buttons Volume down + Power (the standard combination for fastboot login) are pressed, the system may misinterpret this as a command.
- Conflict after unlocking the bootloader: If you unlocked the bootloader but didnβt install a custom recaveri (e.g., TWRP), the system may get stuck on the fastboot screen.
How do you determine your situation? Try to exit fastboot mode in the standard way (press the power button for 10-15 seconds).
- β Turned off and switched on normally - the problem was temporary (e.g. sticking buttons).
- β Booted again in fastboot - it is a system failure or hardware malfunction.
- π Hangs on the logo. MIUI β The boot section is damaged (boot.img).

If the phone is charging in fastboot mode (the battery icon appears), this is a good sign - the hardware is working, and the problem is more software.
How to get out of Fastboot on Xiaomi: step-by-step instructions
The way you exit depends on whether the phone responds to buttons and connects to a computer.
Method 1: Forced resetting
Suitable if the phone responds to buttons, but does not go out of mode.
Press Power button for 10-15 seconds | If it doesn't work, press Power + Volume up for 20 seconds | Wait 1-2 minutes and try to turn the phone on again | If the screen is out but the phone vibrates - release the buttons and give it time to load-->
β οΈ Note: On some models (Redmi Note 8 Pro, POCO X3) If you have a hard reset, you can have a hard reset, and if you have a recovery menu, select Reboot system now.
Method 2: Connect to a PC and a reboot command
If the phone does not respond to buttons, but is determined by the computer, use ADB and Fastboot:
- Download and install Platform Tools (the official tool from Google).
- Connect your phone to your PC through USB-cable (preferably original).
- Open the command line (cmd) in the folder with the platform-tools.
- Enter the command: fastboot devices If the phone is determined (its serial number will appear), type: fastboot reboot
If the fastboot reboot command doesnβt work, try:
fastboot continueThis command keeps the system booted, ignoring errors.
Method 3: Reset to factory settings (Hard Reset)
If the phone is looped on fastboot and does not respond to commands, then the reset remains over the Recovery:
- Turn off the phone (squeeze the power for 15 seconds).
- Press Power + Volume up before the Mi Recovery logo appears.
- Select the language, then Wipe Data β Wipe All Data.
- Confirm the reset and wait for the reset.
β οΈ Warning: This method will delete all data on your phone (photos, contacts, messages) If you have synced with Mi Account, some of the data can be restored after you log in to your account.
What if the sensor in the Recovery is not working?
If the phone does not come out of Fastboot: diagnosis of "brick"
If none of these things worked, and the phone keeps coming back to the screen with the rabbit, it's probably a boot or firmware that's damaged, and it's called a soft brick.
- The phone is turned on, but always gets into fastboot.
- The computer defines the device as Qualcomm HS-USB QDLoader 9008 (Emergency Firmware Mode).
- The screen flashes a red inscription: Invalid partition table or No boot image.
You will need to reflash your phone via the Mi Flash Tool or EDL-Instructions for experienced users:
Download the official firmware for your model from the Xiaomi Firmware website|Install Qualcomm drivers (for mode) EDL)|Unpack the firmware in a folder without Cyrillic symbols|Launch the Mi Flash Tool on behalf of the administrator-->
β οΈ Attention: Firmware through EDL You need an authorized Xiaomi account (for new models). If you don't have access, contact the service center. IMEI.
| Type of brick | Symptoms | Decision |
|---|---|---|
| Soft brick | The phone is powered on but does not load beyond fastboot or the MIUI logo. | Fastboot or Mi Flash Tool. |
| Hard brick | The phone doesn't respond to buttons, it's not determined by a computer, the screen is black. | Firmware through EDL (authentication required) or repair in the service. |
| Bootloop | The phone is constantly rebooted without reaching the desktop. | Reset via Recovery or flashing boot.img. |
Hardware causes: when the fault of the "iron"
If the phone falls, gets wet, or overheats before the fastboot screen comes on, the problem may be in the hardware.
- π Damaged flash memory (eMMC) Symptoms: the phone is defined as QHUSB_BULK In Device Manager, the firmware does not pass (Sahara error).
- π Oxidized contacts: When moisture is ingested, the loading tracks on the motherboard can oxidize.
How to check:
- Connect your phone to charge. If the charging light doesn't go on, it's a power problem.
- Light up the flashlight on the screen at an angle. If you see the Xiaomi logo, but the backlight doesn't work, the display plume is faulty.
- Smell the phone. The smell of the burn indicates burnt elements (most often voltage stabilizers).
β οΈ Warning: If the phone falls or gets wet, don't try to sew it yourself, it can aggravate the damage.
Prevention: How to avoid getting back into the Fastboot
To prevent the rabbit screen from reappearing, follow these rules:
- π Update the firmware only through official channels (Settings) β The phone. β System updates: Avoid "custom" firmware from unknown sources.
- π Do not remove system applications without root rights. Even if they seem useless (for example, Mi Video or Mi Music), their removal can disrupt the work. MIUI.
- π Keep your battery power on track. Don't let it go below 10%, which can damage your file system.
- π‘οΈ Use antivirus. Some viruses (like Triada) can damage the boot partition.
- π§ Don't accidentally press buttons when you're connected. + Power can accidentally transfer your phone to fastboot.
If you are actively experimenting with firmware, install TWRP Recovery β this custom recovery will allow you to make backups of the system before changes and restore the phone in case of a failure.

The most common reason for spontaneously logging into fastboot is an interrupted MIUI update. Always wait for the full file download and don't turn off the phone during the process (even if it's "hang" for 20+ minutes).
