Why your Redmi 9A is showing off the fastboot and what to do about it

You turned on the Xiaomi Redmi 9A, and instead of the usual desktop, you saw a black screen with the words "Fastboot" and a picture of a rabbit in a hat-out-of-the-box? Don't panic - this is not a breakdown, but a service mode that is used to firmware, unlock the bootloader or restore the system. 90% of the time, the problem is solved in 5-10 minutes without losing data.

Fastboot (or fastbootd) is a low-level tool that allows you to interact with the hardware of the smartphone through a computer. On Redmi 9A, it can be activated accidentally (for example, when you press the power and volume buttons), after a failed update or reset, the main thing is not to try to “pull out the battery” (it is non-removable!) and not to press the button at random, so as not to aggravate the situation.

In this article, we will discuss:

• 🔍 What is Fastboot and Why You Need It on Xiaomi

What is Fastboot and why is it needed on Xiaomi Redmi 9A?

Fastboot (or fastboot protocol) is a protocol that allows you to communicate with the hardware of an Android device via the USB-port. On Xiaomi, it is used to:

• 🔓 Unlock the bootloader before firmware custom software.
• 📲 Install official and unofficial firmware via the Mi Flash Tool.
• 🔄 System recovery after failure or “bricking”.
• 🛠️ Testing of hardware components (e.g., touchscreen or communication module checks).

On Redmi 9A (codename dandelion), Fastboot is activated when the Power + Volume buttons are pressed down on the phone turned off. In this mode, the smartphone does not load the operating system, but waits for commands from the user or PC. A screen labeled "Fastboot" and a hare is a normal state, not a mistake!

Distinguished from Recovery Mode: In Fastboot you see a black screen with a white inscription and the Mi Bunny logo, and in Recovery you see a menu with items like Wipe Data or Reboot.

⚠️ Warning: If you didn't plan to flash your phone, getting into a Fastboot isn't a regular situation. Possible causes include an update failure, an application conflict, or a hardware malfunction (such as sticking the volume button).

The reasons for the appearance of Fastboot on Redmi 9A: from accident to failure

On Xiaomi Redmi 9A, Fastboot mode can be activated for the following reasons:

1. Random button clamping (Power + Volume down) when you take your phone out of your pocket or bag. This is the most common reason: just clamp the combination for 5-10 seconds, and the smartphone will go to Fastboot.
2. Failed MIUI Update: If the firmware is interrupted (e.g., the battery is dead or the boot fails), the system can automatically go to Fastboot for recovery.
3. Reset settings via Settings. Sometimes after a hard reset (Settings → Reset → Delete all data), the phone can not boot properly and “hangs” in the Fastboot.
4. Application conflict or viruses. Rarely, but it happens: malware or malfunctioning software can initiate a transition to service mode.
5. Hardware problems: 🔋 Sticking the Loudness button down (often after falling or getting moisture). 🔌 Failure of the button plume or motherboard.

How do you know why you're doing this? If before you start Fastboot, you're:

• 🔄 Updated MIUI → a problem in the firmware.
• 🗑️ Reset settings → the system failed to complete the process.
• 📱 Nothing was done → most likely, a button stuck or a software crash.

⚠️ Warning: If the phone goes to Fastboot on its own every time you restart, it's a sign of damage to the boot or recovery partition, and you'll need to flash it through the Mi Flash Tool.

Method 1: How to get out of Fastboot on Redmi 9A without a computer

If you happen to be on Fastboot, try the standard reboot method:

If the phone doesn't respond:

1. Connect the charger and wait until the charging indicator appears on the screen (even in the Fastboot smartphone can charge).
2. After the battery icon appears, try to clamping the power again for 15 seconds.
3. If the screen is out, but the phone vibrates, release the buttons and wait for the usual boot.

If the phone is back on Fastboot after the reboot:

• 🔋 Try charging the battery to 50% (sometimes a discharged battery interferes with a proper load).
• 📴 Remove the SIM- card and memory card (they may conflict with the system).
• 🔄 Try to pinch Power + Volume up - this can force Recovery Mode to run from where you can make a reset.

⚠️ Warning: If the phone vibrates 3 times in a row when you try to turn on, it is a sign of bootloop ( looped boot).

💡

If the phone doesn’t respond to the buttons, try holding them for 20 to 30 seconds, which can help wake up the phone, especially if the battery is severely drained.

Method 2: Recovery Mode (if the Fastboot doesn't leave)

If a simple reboot doesn’t work, try running Recovery Mode, Xiaomi’s built-in recovery tool.

1. Turn off the phone (squeeze the power for 15 seconds if it doesn't respond).
2. Press Power + Volume up and hold for 10-15 seconds until the Mi logo appears.
3. Release the buttons – you should see the Recovery menu (in English or Chinese).

From the Recovery menu, select:

• 🔄 Reboot → System - an attempt at normal booting.
• 🗑️ Wipe Data → Wipe All Data – Complete reset (deletes all data, but often solves a problem).
• 📥 Connect with MiAssistant – Connect to a PC for recovery (requires Mi PC Suite).

If the menu is in Chinese:

• The first item is (Reboot).
• The fourth point is called “Wipe Data”.

After the Wipe Data reset, the phone will restart and should start as normal, and if not, go to the computer method.

💡

Recovery removes all data, including photos and apps. If your phone had important files, try other ways first or remove the memory card (if you have one).

Method 3: Exit from Fastboot via computer (ADB and Mi Flash)

If the phone is persistently returning to Fastboot, you’ll need a computer with Xiaomi drivers installed and ADB/Fastboot utilities, a method that’s suitable for power users.

Step 1: Installation of drivers and tools

Download and install:

• 🖥️ Platform Tools (ADB + Fastboot) by Google.
• 🔌 Xiaomi drivers for your model (Redmi 9A).
• 📁 Official firmware for Redmi 9A (select the Fastboot version, not Recovery version).

Step 2: Checking the connection

Connect your phone to your PC via the USB- cable (preferably original) and execute in command line (cmd):

fastboot devices

If the device is determined (the serial number will appear), move to the next step. If not, check the drivers or try another USB cable/port.

Step 3: Teams to exit Fastboot

Enter in turn:

fastboot reboot

If your phone is back on Fastboot, try:

fastboot continue

Or a forced reboot in Recovery:

fastboot reboot recovery

Step 4: Flash through the Mi Flash Tool (if nothing helps)

If the commands don't work, you just need to flash the phone:

1. Download the Mi Flash Tool and unpack the Fastboot firmware for Redmi 9A.
2. Launch Mi Flash, press Select and specify the firmware folder.
3. Connect the phone in Fastboot mode (it must be determined in the program).
4. Choose Clean All (complete cleaning) or Clean All and Lock (if you want to lock the bootloader after you have firmware).
5. Press Flash and wait until it is completed (5-10 minutes).

⚠️ Warning: The firmware on Mi Flash deletes all data without recovery, including photos, contacts and apps. Pre-remove the memory card, if you have one.

What to do in Fastboot mode on Redmi 9A

Some actions can turn your phone into a brick. Avoid the following:

• 🚫 Interrupt the firmware (turn off the cable or pull the battery while Mi Flash is running) and this will damage the boot partitions.
• 🚫 Use firmware from other models (e.g., Redmi 9C). Even if they are "similar," it will lead to hardware conflicts.
• 🚫 Enter random Fastboot commands. For example, a fastboot oem unlock without first unlocking the bootloader via the Mi Unlock Tool will lock the phone.
• 🚫 Manually format partitions (fastboot format userdata commands) that delete data without recovery.
• 🚫 Use unofficial firmware (like LineageOS or Pixel Experience) without unlocking the bootloader. This will lead to a bootloop.

If you are not sure of your actions, it is better to contact the Xiaomi service center. The cost of recovery after a failed firmware starts from 1,500 rubles (2026).

Hardware causes: when Fastboot is a symptom of a breakdown

If the phone goes to Fastboot on its own every time it boots up, and the firmware doesn't work, it could be the hardware.

How to check for hardware malfunction:

1. Try to boot up without it. SIM-memory-cards.
2. Connect another charger (preferably original).
3. Check if other buttons are responsive (like Volume Up).
4. Light a flashlight on the screen when turned off - if artifacts (strips, spots) are visible, the problem is in the display or plume.

⚠️ Warning: If the phone is not detected by a computer in Fastboot (not displayed in fastboot devices), but is charging, this is a sign of damage to the USB- port or controller. Self-repair is not recommended!
