Fastboot on Xiaomi Redmi Note 9: why the phone got stuck in this mode and how to remove it

Why your Redmi Note 9 shows the Fastboot inscription and what it means

You turned on the Xiaomi Redmi Note 9, and instead of the usual lock screen, you saw a black background with the words FASTBOOT, white Android robot and Waiting for device status? It's not a fault — the phone fell into engineering mode, which is used to firmware, unlock the bootloader or restore the system. But for the average user, such a screen means one thing: the smartphone is temporarily unusable.

Fastboot Mode is a low-level tool built into all Xiaomi devices based on Qualcomm processors (including the Redmi Note 9 with the Helio G85 chipset), which is activated when certain button combinations, update failures or improper shutdown during firmware. In 90% of cases, it takes less than a minute to leave, but if you have never experienced it, the instructions below will help you to understand without risking damage to the phone.

It's important to understand that Fastboot is not Recovery. In the first case, the phone waits for commands from the computer via ADB, in the second case, it offers a menu to reset or install updates from the memory card. On Redmi Note 9, the transition between these modes is carried out by holding the Volume + or Volume button when turned on.

The reasons for the appearance of Fastboot mode on the Redmi Note 9: why the phone itself went into this mode

The smartphone doesn’t just go to Fastboot, it’s always preceded by a user action or system failure, and here are the most common reasons for the Redmi Note 9 (model M2003J15SC):

• 🔄 Failed update MIUI: air-flash" (OTA) or through the Mi Flash Tool can block the bootloader in the standby command mode.
• 🔧 The combination of buttons when turned on: simultaneous retention Power + Loudness – More than 5 seconds forced Fastboot activation.
• 📱 Failure after unlocking the bootloader: if you tried to get Bootloader Unlock through the official Xiaomi tool, but interrupted the process.
• 🔋 Critical battery discharge: If the phone is turned off at a charge level below 5% during the upgrade, the system can “hang” in the Fastboot.
• 🛠️ Incorrect recovery through TWRP: Installation of custom recavator without unlocked bootloader leads to a reboot cycle in Fastboot.

On the Redmi Note 9, Fastboot mode can also appear after connecting to a PC with Qualcomm or MediaTek drivers installed (even if you were just charging the phone), in which case the system recognizes the attempt to interact through ADB and goes into waiting for commands.

How to exit Fastboot on Redmi Note 9: the easy way (without a computer)

If the phone just “hangs” in Fastboot mode for no apparent reason (for example, after a reboot), try the standard exit method:

1. Hold the Power button for 10-15 seconds until the screen goes out.
2. Wait 30 seconds, then press Power again for normal turn on.

If this doesn’t work, use a combination of buttons:

1. Turn off the phone with long power retention.
2. Press Power + Volume + for 5-7 seconds until the MI logo appears.
3. Release the buttons – the phone should boot in normal mode.

The Redmi Note 9 also uses an alternative method: once the Fastboot screen appears, plug the charger in and hold Volume + and Volume for 10 seconds at the same time, which forcefully restarts the system, bypassing the bootloader.

Exiting from Fastboot via Recovery Mode: If the phone doesn’t respond to buttons

If you can’t remove Fastboot with a simple reboot, try resetting your settings and resetting your Fastboot, which works even when your system files are corrupted, but will delete all your internal memory (photos, apps, accounts).

1. Turn off the phone (hold power for 20 seconds if it doesn't respond).
2. Press Power + Volume + and hold until the Recovery menu appears (MI logo with Android robot on the back).
3. Use volume buttons for navigation and power to select Wipe Data (or Factory Reset).
4. Confirm the reset with Yes and wait for completion (5-10 minutes).
5. Go back to the main menu and select Reboot → Reboot to System.

If the phone is resetting, it will be damaged by the firmware, in which case you will need to reflash the device via the Mi Flash Tool (instruction below).
