Xiaomi Redmi 9 is one of the most popular budget smartphones, but even it is not immune to unexpected crashes. One of the most frightening moments for users is the sudden appearance of the Fastboot inscription on a black screen with a picture of a bunny in a hat-ear. What does this mean? Why does the phone stop loading normally? And most importantly, how to bring the device back to life without contacting the service center?
Fastboot Mode is a low-level tool for running your smartphone firmware, which is used to flash, unlock the bootloader, or restore the system, but if you didn’t plan on any software manipulation, it signals a serious problem. In this article, we’ll look at why Redmi 9 (including Redmi 9A, 9C, 9T) can get stuck in this mode, and what to do about it.
It's important to understand that Fastboot is not a sentence. In 90% of cases, you can solve the problem yourself, even without special skills, but you need to act carefully so as not to aggravate the situation. Next, step-by-step instructions for different scenarios, from the simplest to the most advanced.
What is Fastboot on Xiaomi and Why it Appears
Fastboot Mode (sometimes called Bootloader Mode) is a protocol that allows you to interact with the Android device bootloader via a mobile phone. USB-Unlike normal operating mode, it doesn't load the operating system, but only basic commands for managing memory partitions are available.
On the Redmi 9 screen, you will see:
- 🐰 Mi Bunny logo (bunny in hat) on a black background
- 🔧 Inscription FASTBOOT or Fastboot Mode
- 🔌 Connection indicator USB (if the cable is connected)
- 📱 The locking notification (This device is locked)
The reasons for getting into Fastboot fall into two categories:
| Type of cause | Specific examples | Can I eliminate it myself? |
|---|---|---|
| Programmatic failures | Misfitting MIUI update, application conflict, resetting settings via Recovery | Yes, 95% of the time. |
| Hardware problems | Damage to the USB connector, power button malfunction, phone fall | Partially (diagnosis required) |
| User actions | Wrong firmware through Mi Flash, attempt to unlock the bootloader | Yeah, but you need knowledge. |
| Systemic errors | Boot or recovery partition damage, broken firmware files | Yeah, through the flashing. |
The most common reason for Redmi 9 is a failure when updating MIUI via About Phone → System Update. If there is a communication breakdown, battery drain or forced restart during the download or installation of firmware, the phone can “hang” in the Fastboot.
- 🔄 Incorrect exit from Recovery mode (for example, select Reboot to Fastboot)
- 🔌 Connecting to PCs with installed drivers ADB/Fastboot and random execution of a command
- 📱 Installation of custom Recovery (e.g, TWRP) loader-free
How to Get Out of Fastboot on Redmi 9: Simple Ways to Get Out
Before you start complex manipulations, try the standard Fastboot exit methods, which work 70% of the time and don’t require a computer connection.
Method 1: Forced resetting
The fastest method is to restart your phone hard.
- Press the power button for 15-20 seconds.
- If the screen goes out and the Redmi logo appears, release the button.
- Wait for the system to load fully (it can take up to 5 minutes).
If the phone returns to Fastboot again, move on to the next method.
Method 2: Button combination
Redmi 9 has a hidden combination to exit the service modes:
- Hold the power button + increase the volume at the same time for 10-15 seconds.
- Release them when the screen goes out.
- Press the power button once for normal download.
This works if the failure was temporary, and if it wasn't, you'd have to connect to a PC.
☑️ Preparing to exit Fastboot
Method 3: Download to Recovery Mode
If the phone doesn’t leave Fastboot but responds to buttons, try booting into Recovery mode:
- Turn off the phone (hold the power button for 20 seconds).
- Press the power + increase the volume until the Mi logo appears.
- Release the buttons when you see the Recovery menu.
- Select the Reboot option → Reboot to System.
⚠️ Note: If the Recovery displays a No command error or a menu in Chinese, it means that the recovery section is corrupted.
Exit from Fastboot via computer: step-by-step instructions
If simple methods don’t work, you’ll have to connect Redmi 9 to your PC and use ADB and Fastboot utilities, which require you to install drivers and have minimal command line knowledge.
Step 1: Installation of drivers and tools
Download and install:
- 🖥️ Android SDK Platform-Tools (official package from Google with adb and fastboot)
- 🔌 Xiaomi Drivers (you can take from the Mi Flash Tool package)
- 🔄 Check that the PC is enabled debugging USB (control panel → The device should not have exclamation points near Redmi 9)
Unpack the platform-tools in the root of the C:\ disk for convenience (the path should not contain Cyrillic!).
Step 2: Checking the connection
Connect your phone to your PC through USB-cable (preferably original) and execute in the command line:
fastboot devicesIf the device serial number appears in the response (e.g. 123abc456def), the connection is successful.
- 🔄 Check the cable and port USB (Try another port, better. USB 2.0).
- 🔧 Reinstall drivers in Device Manager.
- 📱 Try another computer.
Step 3: Teams to exit Fastboot
Enter the following commands in turn:
fastboot rebootIf the phone is restarting normally, the problem is solved.
fastboot continueThis command keeps the system booted, ignoring errors.
⚠️ Note: If the phone returns to Fastboot after fastboot, it means that the boot partition is damaged.
💡
If the fastboot reboot command doesn't work, try running fastboot oem reboot-edl first, and then fastboot reboot again.This sometimes helps with the bootloader "hang."
Redmi 9 Fastboot Fastboot Flashing: When You Need It
If all the previous methods didn't work, the last option is to completely reflash through the Fastboot, which is a radical solution, but it's guaranteed to bring the phone back to life, and minus all the data on the device will be erased.
Preparation for firmware
You'll need:
- 🖥️ Windows computer 7/10/11 (on Mac/Linux Possible problems with drivers).
- 🔌 Original. USB-cable (do not use extension cords!).
- 📱 Firmware for Redmi 9 in.tgz or.zip format (download from the official Xiaomi website).
- 🔧 The Mi Flash Tool.
Important: choose firmware for your model! For Redmi 9, it's lancelot, for Redmi 9A, it's dandelion, for 9C, it's angelica.

Follow the instructions:
- Unpack the downloaded firmware into a folder without spaces (for example, C:\MIUI\lancelot).
- Run the Mi Flash Tool on behalf of the administrator.
- Click Select and point the way to the firmware folder.
- Connect the phone off in Fastboot mode (hold power + volume down when connecting the cable).
- The program will show the serial number of the device – press Refresh.
- Select the firmware method: Clean all (recommended for serious crashes); Clean all and lock (clean + lock the bootloader (if unlocked); Save user data (not always working).
Flash
Once the firmware is successful, the phone will automatically restart. The first turn on can take up to 15 minutes — that's okay.

Frequent Mistakes and How to Avoid Them
When using Fastboot, users often face typical problems, and here are the most common ones and how to solve them:
| Mistake. | Reason. | Decision |
|---|---|---|
| Waiting for device in the command line | Drivers are not installed or the cable is faulty | Reinstall drivers, try another cable/port |
| The phone doesn't respond to the buttons. | Hardware failure (power button or plume) | Connect to charging for 30 minutes, try to pinch the buttons stronger |
| Anti-rollback error when running | Trying to flash the old version of MIUI | Download a newer firmware or use Fastboot Script |
| After the firmware, the phone does not turn on. | Incorrectly selected version of the firmware | Repeat the firmware with the correct version for your model |
Another common problem is that the phone leaves the Fastboot, but it loads into an endless bootloop cycle, which means that the system is damaged, but the boot partition is loading.
- Load into Recovery (Power + Volume Increase).
- Choose Wipe Data → Wipe All Data.
- Reboot the phone.
If that doesn’t work, it’s just a full flash through the Mi Flash Tool.
💡
Never interrupt the firmware process! USB-Cable or PC shutdown at this point can cause the phone to “brick” (completely inoperable).
How to Prevent Fastboot from Coming in the Future
To avoid repeat issues with Fastboot on Redmi 9, follow these guidelines:
- 🔄 Update. MIUI Only through official channels (Settings) → The phone. → System updates: Do not use third-party firmware unless you are sure of its origin.
- 📱 Do not interrupt the upgrade process – monitor the battery level (minimum 50%) and the stability of the Internet connection.
- 🔧 Don't experiment with unlocking the bootloader unless you understand the consequences. This will void the warranty and increase the risk of failure.
- 🛡️ Install only verified applications – some programs (for example, to speed up the phone) can damage system files.
- 🔋 Avoid full battery discharge – this can cause failures on the next load.
If you are actively using custom firmware or TWRP, you must:
- 📋 Make a backup section. EFS (responsible IMEI).
- 🔄 Check firmware compatibility with your Redmi 9 model.
- 🔧 Use only proven tools (e.g. OrangeFox Recovery instead of legacy versions) TWRP).
Compliance with these rules will reduce the risk of getting into Fastboot to a minimum.
