How to Get Out of Fastboot on Xiaomi Redmi 9: 5 Ways to Work

Fastboot mode on Xiaomi Redmi 9 is a utility tool for firmware and recovery of the smartphone, but sometimes the device gets stuck in it for no apparent reason. You will see a black screen labeled FASTBOOT and a white robot Mi Bunny — and the phone does not respond to conventional buttons. The reasons are different: from accidental keystrokes to firmware failure. Don't panic — 90% of the time the problem is solved without going to the service center.

This guide covers all the current ways to exit Fastboot on Redmi 9 (models M2003J15SC/M2003J15SS/M2003J15SG), including software and hardware methods. We will understand when reboot is enough, and when you need to flash through MiFlash or even unlock the bootloader. All the steps are tested on the current versions of MIUI 14 and HyperOS (2026).

⚠️ Note: If your Redmi 9 hit the Fastboot after a failed firmware or unlocking the bootloader, some methods may not work. In this case, immediately go to the section about flashing through MiFlash.

1. Simple Reboot: When Helps and How to Do It Right

Half the time, Redmi 9 gets stuck in the Fastboot because of a temporary system failure. Before you resort to radical measures, try a standard reboot — not the usual way, but through a forced power outage.

Here's how it works:

• 🔄 Press the power button for 15 to 20 seconds until the screen goes out. On the Redmi 9, it takes longer than on other models - don't let go ahead of time.
• ⚡ Wait 30 seconds after shutdown (this is important – the capacitors must be completely discharged).
• 📱 Press the power button again to turn the phone on. If you're lucky, the device will boot as normal.

If Redmi 9 is back on Fastboot after that, the problem is deeper - it may be the firmware is damaged or the MIUI modules conflict.

Hard Reset: When and How to Use

Hard reset (or Wipe Data) is a last resort that erases all data on the phone, but often saves from a loopy Fastboot. On Redmi 9, this method works even if the device does not boot into the system.

Instructions:

1. Turn off the phone with a long press of the power button (as in the previous section).
2. Press the power + volume button up simultaneously for 10-15 seconds until the Mi logo and Recovery menu appear.
3. From the Recovery menu, select Wipe Data → Wipe All Data (use volume buttons for navigation, power button for confirmation).
4. Confirm the action and wait for the process to be completed (it will take 2-5 minutes).
5. Choose Reboot. → Reboot to System.

⚠️ Warning: After a hard reset, all photos, contacts and apps will be deleted, and if you have Mi Account enabled and synced, some of the data can be restored after you log in to your account.

3.Using Mi Assistant: The Official Way Xiaomi

If the phone doesn't respond to a reset, but is determined by a computer, try Mi Assistant, Xiaomi's official system recovery utility, which automatically picks up the firmware and reflashes the device without manually searching for files.

Step-by-step:

1. Download Mi Assistant from the official website (Windows version).
2. Connect Redmi 9 to your PC via the original USB-cable (importantly, cheap cables may not transmit data).
3. Start Mi Assistant, select Reset Device.
4. Follow the instructions of the program - it will download the firmware itself and install it.
5. After completion, the phone will restart in normal mode.

Mi Assistant works even with a locked bootloader, but requires authorization in the Mi Account tied to the phone, and if you forget your account details, this method will not work.

4. Flashing through MiFlash: for power users

If previous methods have failed, manual flashing through MiFlash remains, and this method requires an unlocked bootloader (if locked, see Section 5) and a suitable firmware.

What you need:

• 🖥️ Windows computer 10/11 (on macOS/Linux MiFlash is not working).
• 🔌 Original. USB-cable (better from the set).
• 📁 Firmware for Redmi 9 (download from Xiaomi Firmware Updater).Select the Fastboot version, not Recovery!
• 🛠️ MiFlash (last version).

Instructions:

1. Unpack the downloaded firmware in a folder without Cyrillic characters (for example, C:\redmi9_firmware).
2. Install MiFlash and Qualcomm drivers (see spoiler in the previous section).
3. Turn off the phone and press the power button + volume down to log into the Fastboot.
4. Connect Redmi 9 to your PC. In MiFlash, press Select and specify the firmware folder.
5. Select Clean All mode and press Flash.
6. Wait for the end (10-15 minutes) and the phone will reboot automatically.

⚠️ Note: If MiFlash gives an error critical partition flashing is not allowed, then the bootloader is locked. Unlock it (section 5) and try again.

5. Unlock the bootloader: if MiFlash refuses to work

If MiFlash is giving out errors related to a locked bootloader, it will have to be unlocked. Xiaomi officially allows this, but the process takes up to 72 hours due to the account verification.

What do you need?

• 📱 Phone with Mi Account tied (must be added to device before problem!).
• 💻 Computer with Mi Unlock Tool.
• 🔑 SIM-Mobile Internet card (to confirm your account).

Step-by-step process:

1. Download and install the Mi Unlock Tool.
2. Log in to Fastboot on Redmi 9 (Power button + Volume down).
3. Connect your phone to your PC and start the Mi Unlock Tool.
4. Sign in with the same Mi Account as you do on your phone.
5. Press Unlock and wait for confirmation (may take up to 3 days!).
6. After unlocking, repeat the firmware through MiFlash.

If you did not tie Mi Account to the phone before the breakdown, you will not be able to unlock the bootloader - you will need to contact the service center with proof of purchase.

💡

Before unlocking the bootloader, disable two-factor authentication in Mi Account, which can block the process. Also make sure that the phone is on mobile Internet (even if it is not catching the network, SIM-map must be inserted).

6. Hardware problems: when it is not the fault of software

If none of these methods worked, the problem may be in the iron:

• 🔋 Sat battery: If the battery is under 5%, the phone will not be able to exit the Fastboot. Charge it for 15-20 minutes off (even if there is no charging indication on the screen).
• 🔌 Damaged. USB-port: if the phone is not detected by the PC but is charging, the problem is the data contacts.
• 🛠️ Faulty power button: If the phone spontaneously enters the Fastboot, it may have stuck or broken the button.

How to check for hardware faults:

1. Connect Redmi 9 to another charger. If the charging indicator does not appear, the problem is in the port or battery.
2. Try to log in to Recovery (power + volume up). If you can't, it's possible that the motherboard is damaged.
3. Light the flashlight in USB-port – if bent contacts or oxidation are visible, repairs are required.

⚠️ Warning: If your phone falls into water or is mechanically damaged, don’t try to sew it yourself, as this can permanently disable the flash memory.

💡

If Redmi 9 doesn’t respond to any of the instructions, but it warms or vibrates when connected to the charge, there’s a 90% chance the hardware is the problem.

7.How to avoid getting back into the Fastboot

To prevent Redmi 9 from getting stuck in Fastboot, follow these rules:

• 🔄 Do not update the firmware through OTA, If the battery is below 50%.
• 🛡️ Do not install custom firmware without unlocking the bootloader.
• 🔌 Avoid cheap ones. USB-cables when connected to a PC – they can cause failures in data transmission.
• 📱 Do not press the power and volume buttons at the same time without the need to.

It is also recommended that:

• Regularly back up through Settings → System → Backup.
• Enable Mi Cloud and data synchronization (contacts, photos, notes).
• Periodically check the state of the battery in Settings → Battery – if the capacity has fallen below 70%, replace the battery.

If you experiment with firmware often, install TWRP Recovery, which will help you recover from backups without the risk of getting into Fastboot.
