Xiaomi’s Fastboot Mode: Why Your Phone Hung and How to Fix It Without Losing Data

You turned on a Xiaomi, Redmi or POCO smartphone, and instead of the usual desktop, a black background appeared on the screen with a green robot and the inscription FASTBOOT MODE? Don't panic - this is not a breakdown, but the system mode that is used to firmware, unlock the bootloader or restore the device. However, if the phone is getting stuck in the Fastboot and does not respond to buttons, urgent intervention is required.

80% of the time, the problem is solved in 5-10 minutes without going to the service center, the main thing is to correctly determine the cause of the failure, this can be a random keystroke, an interrupted firmware update, a custom recovery conflict, or even a hardware failure of the power controller. In this article, we will discuss all the working ways to exit the Fastboot, including the hidden functions of the Mi Flash Tool and ADB commands that are not described in the official Xiaomi forums.

Warning: If you see on the screen the words "This device is locked" or "Device is corrupted", this is a separate case - it requires unlocking the bootloader or flashing through EDL Mode. These situations we will also consider, but at the end of the article, as they are more complex and risky for beginners.

Why Xiaomi is stuck in Fastboot mode: 5 main reasons

Fastboot (or Bootloader Mode) is a low-level smartphone state where only basic commands are available to interact with the bootloader. Normally, it is activated intentionally, for example, when you run through Mi Flash or unlock the bootloader. But if the phone hit the FASTBOOT on its own, one of the following factors is to blame:

• 🔄 Accidental pressing of the button combination (Loudness down) + Power, especially for Redmi Note models 10/11 and POCO X3/X4, where the buttons are not located.
• 📱 Firmware failure or OTA-If the update process is interrupted (battery is depleted, disconnected) USB), The system can get stuck in the Fastboot.
• 🔧 The conflict of custom recaveri (TWRP, OrangeFox.com: Incorrect installation of a recovery or incompatible version often results in a download cycle.
• 🔋 Battery or power controller problems: If the phone is dead or connected to a faulty RAM, the bootloader may refuse to start the system.
• 🛠️ Hardware failure (damage to the motherboard, oxidation of contacts) In this case, the Fastboot is the last stronghold of the phone before complete death.

How do you know what caused this? Notice the additional captions under the Fastboot logo:

⚠️ Warning: If the screen is on fire SECURE BOOT ERROR or INVALID IMAGE, This means that the bootloader is damaged, and the intervention itself can lead to a complete blink, in which case it is better to contact the service.

Method 1: Simple reboot (works 60% of the time)

If the phone hit FASTBOOT MODE due to accidental button pressing or a mild failure, it is enough to forcefully restart it.

1. Press the power button for 10-15 seconds until the screen goes out.
2. Wait 30 seconds (even if the screen is not turned on).
3. Press the power button again to turn on the phone.

If this method doesn’t work, try an alternative combination:

• 🔄 Hold the Loud up. + 10 seconds power.
• 🔄 If it doesn't help, the volume is up. + Loudness down + Food (for some models) POCO F and Redmi K).

On models with a non-removable battery (for example, Xiaomi 12/13, Redmi Note 12 Pro+) you may need to wait up to 1 minute - sometimes the power controller "hangs" and slowly resets.

💡

If the phone vibrates when you press the buttons, but the screen remains black, this is a sign of hardware failure of the display, not a problem with the Fastboot. Try connecting the smartphone to an external monitor via USB-C → HDMI (if the model supports Miracast).

Method 2: Exit the Recovery Menu (if the buttons don't work)

If forced reboot doesn't work, try entering Recovery mode and restarting the system from there, even on locked bootloaders.

Instructions:

1. Turn off the phone (press Power + Volume up for 10 seconds).
2. Once the screen goes out, immediately press Volume Up + Power and hold until the Mi logo appears.
3. Release the buttons and you will see the Recovery menu (usually in Chinese or English).
4. Use volume buttons for navigation and power to select Reboot → Reboot to System.

If the Recovery menu is in Chinese, focus on the icons:

• 🔄 Reboot – the first icon with a circular arrow.
• 📱 Log in to the system - an icon with a phone and a tick.

⚠️ Note: On some firmware (for example, MIUI Global Stable for Redmi 9/10) Reboot to System may not be available, and in this case, select Reboot, and the system will determine where to boot.

Method 3: ADB commands (for advanced users)

If the phone is detected by the computer in Fastboot mode, but does not leave it in standard ways, you can use it. ADB-This method requires installed drivers and minimal command line knowledge.

Step-by-step:

1. Download and install Google’s Platform Tools (ADB & Fastboot).
2. Connect your phone to your PC through the original USB-cable (important!).
3. Open the Command Prompt (Windows) or Terminal (Mac/Linux) in the folder with Platform Tools.
4. Enter the command to check the connection: fastboot devices If the phone is determined (its serial number will appear), continue. If not, install the Xiaomi USB Drivers drivers.
5. Run the reboot command: fastboot reboot

If a simple reboot doesn’t work, try alternative commands:

• 🔄 Recovery: Fastboot Reboot Recovery
• 📱 Reboot to system (if Recovery is not available): fastboot reboot bootloader Then immediately: fastboot reboot

On some Xiaomi models (e.g. Mi 11 Ultra, Redmi K50) fastboot commands may not work due to Anti-Rollback locking, in which case only firmware via Mi Flash (Method 5) will help.

Method 4: Charge the battery (if the phone doesn't respond)

If the smartphone does not respond to any buttons and the Battery low or Charging is on the screen, the problem is the battery is discharged. In Fastboot mode, the phone consumes more power than in its normal state, so even 5-10% of the charge may not be enough to exit.

What to do:

1. Connect the phone to the original charger (at least 18 watts).
2. Leave to charge for 20-30 minutes (even if the indicator is not on).
3. Try rebooting with buttons (Power + Volume up for 10 seconds).

If the charging indicator does not appear:

• 🔌 Try another charger or cable (better from Xiaomi).
• 🔋 Connect to Power Bank – sometimes helps with power controller failures.
• 🔌 Check the charging port for debris (clean your toothpick carefully).

⚠️ Warning: If the phone stays cold after 30 minutes of charging (it doesn't heat up), this may indicate a power circuit break, in which case a diagnosis is required in the service - self-repair can be fraught with short circuit.

Method 5: Firmware via Mi Flash Tool (extreme case)

If none of the previous methods worked, you can still use the Mi Flash Tool to reflash your phone, and this method works even if you have a problem with it.

• 📱 The phone is cyclically rebooted in Fastboot.
• 🔧 Device is corrupted or This device is locked.
• 🔄 Recovery is unavailable or damaged.

Step-by-step:

1. Download the official firmware for your model (select Fastboot ROM, not Recovery ROM).
2. Unpack the archive into a folder without Cyrillic characters (e.g., C:\Xiaomi\ROM).
3. Download and install the Mi Flash Tool.
4. Connect your phone in Fastboot mode to your PC.
5. Launch Mi Flash, press Select and point the path to the firmware folder.
6. At the bottom, select firmware mode: Clean all – clean (removes all data!), Clean all and lock – clean + lock bootloader (for sale of the phone), Save user data – save data (does not work on all models).

Flash

Important! Once the firmware is in place, the phone can:

• 🔄 Reboot several times is normal.
• 📱 Hang on the Mi logo for 5-10 minutes (don’t turn off!).
• 🔧 Require re-assignment of your Mi Account (if Find Device was enabled).

⚠️ Note: Firmware via Mi Flash on models with a locked bootloader (for example, Xiaomi 14, Redmi Note 13 Pro)+) It requires prior unlocking through the Mi Unlock Tool, without which the phone will turn into a brick».

💡

Firmware via Mi Flash is the most reliable way to bring your phone back to life, but it deletes all data. Always back up important files in advance!

Method 6: Unlock the bootloader (if the phone is locked)

If you see this device is locked on the Fastboot screen, it means that the bootloader is locked and further action requires unlocking it. Xiaomi locks the bootloader on all new models to protect against unauthorized access.

How to unlock:

1. Download Mi Unlock Tool from the official website.
2. Sign in to your Mi Account (it should be linked to your phone!).
3. Connect your phone in Fastboot mode to your PC.
4. Run Mi Unlock, follow the instructions (SMS confirmation may be required).
5. Wait until the process is completed (usually 1-3 minutes).

After unlocking:

• 📱 The phone will automatically reboot.
• 🔧 Now you can sew custom firmware or install TWRP.
• ⚠️ But: Unlocking resets all data and disables Find Device and Mi Cloud features!

Starting with the Xiaomi 12 and Redmi Note 11, Xiaomi introduced a 72-hour waiting period before unlocking.

1. You're sending a request to unlock.
2. You have to wait 3 days (the phone has to be connected to the Internet!).
3. Only then can the loader be unlocked.

What do you do if nothing helps?

If you've tried all the ways, but the phone is still stuck in the Fastboot, it may be a hardware problem.

• 🔥 The phone is very hot (especially in the processor area).
• 🔌 Not detected by the computer even after installing the drivers.
• 📱 Artifacts appear on the screen (stripes, flickering).
• 🔋 The battery does not charge at all (even after cleaning the port).

Typical hardware reasons:

If you decide to repair yourself, consider:

• 🛠️ To replace the tank or plume will require a soldering station and experience with microelectronics.
• 🔧 Details are better to order on AliExpress using the exact phone model (for example, “capacity for Redmi Note 10 Pro»).
• ⚠️ Risk! Incorrect soldering can lead to short circuit and complete death of the motherboard.

💡

If you have a warranty, don't open it yourself, and if you do, you can contact Xiaomi's official service, even if they say it's not a warranty, and sometimes you get a free repair through a support call.
