Fastboot mode on Xiaomi Redmi 9C is a utility tool for firmware, unlocking the bootloader or restoring the system. However, sometimes the smartphone gets stuck in this mode after a failed update, resetting or experimenting with custom firmware. If your Redmi 9C screen is FASTBOOT with the image of a hare in the hat, and the phone does not respond to standard buttons, do not panic. In 90% of cases, the problem can be solved without going to the service center.
In this article, we’ll look at 5 proven ways to exit Fastboot, including “soft” (no data loss) and “hard” (full reset), and why Redmi 9C can freeze in this mode, how to prevent repeated crashes, and what to do if none of the methods worked. All instructions are adapted specifically for the Redmi 9C model (codenamed angelica) and tested on current versions of MIUI.
Why is Redmi 9C in Fastboot mode?
Fastboot mode is activated on Xiaomi when:
- 🔄 Interrupted update MIUI (via Ota Updater or Mi Flash Tool).
- 🔓 Attempt to unlock the bootloader with errors.
- 📱 Incorrect reset to factory settings (via Recovery or ADB).
- 🔋 Abrupt power outage during critical operations (firmware, battery calibration).
- 🛠️ Installation of incompatible custom firmware (for example, LineageOS for another model).
Redmi 9C is most likely to crash due to a firmware version conflict, such as if you tried to roll back from MIUI 14 to MIUI 12 without a full wipe, or if you installed firmware for another modification (e.g. Redmi 9A instead of 9C), or if you were trying to crash the boot or recovery partition that prevents the system from booting normally.
Another common cause is hardware malfunctions:
- 🔌 Unstable power supply (discharged battery or damaged) USB-cable when running through Mi Flash).
- 💾 Damaged memory (eMMC) that prevents the system from reading critical files.
- 🔌 Problems with the power button (false positives when booting).
Method 1: Reboot via button combination (without data loss)
The simplest and safest method is forced reboot, which works if the Redmi 9C system is intact and the failure is due to a temporary conflict.
Hold the power button. 10-15 seconds|Release the button after vibration|Wait for the logo to appear. MI|If the screen is gone, press the power again.-->
If the Redmi 9C doesn’t respond to a long power button hold, try an alternative combination:
- Press the Power button + Volume up for 10-20 seconds.
- Release the buttons when the screen goes out (even if the FASTBOOT logo is not gone).
- Wait 1-2 minutes – sometimes the system is delayed.
⚠️ Warning: If the phone gets back into Fastboot after the reboot, it means that the system files are damaged, in which case you will need to restore through Recovery or flashing.
Method 2: Exit via Mi Assistant (Official Xiaomi Tool)
If the button combinations didn’t work, use Mi Assistant, Xiaomi’s official smartphone diagnostic and recovery utility, which lets you log out of Fastboot without manually entering commands.
Download Mi Assistant from Xiaomi's official website (select the Redmi 9C version). The utility runs on Windows 7/10/11 and requires ADB/Fastboot drivers installed.
💡
If the Mi Assistant doesn’t recognize the phone, try connecting it to another phone. USB-port (preferably) USB 2.0 on the back of your PC or use the original Xiaomi cable.
Instructions for use:
- Connect Redmi 9C to your PC via USB (Fastboot mode must be enabled).
- Run Mi Assistant and wait for the program to identify the device.
- In the main menu, select Unbrick (Recovery after a crash).
- Follow the tips of the wizard - the utility will automatically download the desired firmware and restore the bootloader.
| Benefits of Mi Assistant | Deficiencies |
|---|---|
| ✅ Automatic definition of model and version MIUI | ❌ It requires a stable internet connection (downloading). ~2 GB of data) |
| ✅ Stores user data (unless the userdata partition is damaged) | ❌ It only works on Windows. |
| ✅ Supports unlocking the bootloader (if the Mi Account is tied) | ❌ It might not work on custom firmware. |
⚠️ Note: If the Mi Assistant offers Clean All, it means that the userdata partition is corrupted, in which case the data will be lost, but the phone will return to working condition.
Method 3: Fastboot commands via ADB (for power users)
If previous methods didn’t work, try manual commands via ADB/Fastboot.This method requires drivers installed and minimal command line knowledge.
Download Platform Tools (includes fastboot and adb) from the Android Developers website. Unpack the archive at the root of the C:\ drive for convenience.
Open the Command Prompt (Win + R → enter cmd) and execute commands in order:
cd C:\platform-tools
fastboot devicesIf the device is determined (the serial number will appear), enter:
fastboot continueThis team is trying to keep booting the system. If it doesn't work, try:
fastboot reboot recoveryThis will reboot the phone in Recovery Mode, from where you can make a reset or install firmware.
What if the fastboot can’t see the device?
⚠️ Note: Fastboot erase or fastboot flash commands can permanently delete data. Do not use it unless you are sure of the action!
Method 4: Recovery through Recovery Mode
If the phone is loaded into Recovery (after the command fastboot reboot recovery or through buttons), you can:
- 🔄 Reset the settings (Wipe Data).
- 📦 Install firmware from the memory card.
- 🔧 Restore a backup copy (if any).
To get to Recovery on Redmi 9C:
- Turn off the phone (hold the power button for 20 seconds).
- Press the Power button + Volume up before the MI logo appears.
- Release the buttons when the Recovery menu appears (in English or Chinese).
On the Recovery menu:
- Select Wipe Data → Wipe All Data (full reset).
- Confirm the action (it may be necessary to enter a password from your Mi Account).
- After reset, select Reboot → Reboot to System.
If the reset didn’t help, try installing the firmware manually:
- Download fastboot firmware for Redmi 9C (for example, with Xiaomi Firmware Updater).
- Place the.zip file on the memory card (in the root directory).
- In Recovery, select Install Update → Choose from SD Card.
- Specify the downloaded file and wait for the installation to end.
💡
If Recovery doesn't start or if it gives an E:unknown command error, it means that the recovery partition is corrupted, in which case only the firmware through the Mi Flash Tool will help.
Method 5: Complete flashing through the Mi Flash Tool (extreme method)
If all the previous methods failed, it leaves the Mi Flash Tool completely reflashed, which erases all the data, but brings the phone back to life.
You'll need:
- 💻 Windows computer.
- 🔌 Original. USB-cable.
- 📁 Fastboot firmware for Redmi 9C (for example, angelica_global_images_...).
- 🔓 Unlocked loader (if previously blocked).
Steps:
- Download and install the Mi Flash Tool from the official website.
- Unpack the firmware in a folder without Cyrillic characters (for example, C:\Redmi9C\).
- Connect Redmi 9C in Fastboot mode to your PC.
- In the Mi Flash Tool, click Select and specify the firmware folder.
- Select Clean All (full reset) or Save User Data (save data if possible).
- Press Flash and wait until the end (5-10 minutes).
⚠️ Note: If the Mi Flash Tool gives an error critical partition flashing is not allowed, it means that the bootloader is locked:
- Apply for unlocking through the official Xiaomi website.
- Connect your Mi Account to your phone (if not tied).
- Repeat the firmware after unlocking.
What do you do if nothing helps?
If none of the methods worked, the problem could be hardware:
- 🔋 Battery discharge: Connect your phone to charging on 30-60 minutes, then try again.
- 💾 Damaged Memory: If the phone is not detected in either Fastboot or Recovery, the eMMC memory may have failed.
- 🔌 Problems with USB-Port: Try connecting your phone to another PC or using it OTG-adapter.
It's also worth checking out:
- 🔄 Mi Account: If the phone is linked to an account, it may require authorization after reset. Make sure you remember your login and password.
- 📡 Regional firmware: Installing firmware for another region (e.g., Chinese on the global model) can cause conflicts.
If the Redmi 9C is still not coming out of Fastboot, contact Xiaomi's authorized service center.In some cases, memory soldering or motherboard replacement is required.
