What is Fastboot on Xiaomi and why does it turn on itself?

Fastboot (or bootloader) mode is a low-level Android device boot mode designed to:

• 🔄 Installation of custom firmware (custom) ROM)
• 🔓 Unlock the loader (OEM Unlock)
• 🛠️ System Recovery After Failures
• 📱 Firmware of individual partitions (for example, recovery or boot)

On the Redmi Note 8T (model M1908C3XG), the Fastboot can be activated automatically in the following cases:

If your Redmi Note 8T loads into the Fastboot every time it turns on, the problem is likely to be a damaged boot partition or incorrect boot boot settings, in which case you will need to flash it.

Method 1: Exit from Fastboot without computer (buttons)

If the smartphone just hovers in Fastboot mode, but physically reacts to button presses, try the standard method:

1. Hold the power button for 10-15 seconds until the screen goes out.
2. After the vibration, immediately press the combination: Volume Up + Power Hold until the MI logo appears.
3. In the Recovery menu, select Reboot → System (use volume buttons for navigation and Power for confirmation).

If after these actions the smartphone is loaded again in Fastboot, then the problem is deeper – perhaps damaged bootloader or system files.

Method 2: Disable Fastboot via ADB (for power users)

If the smartphone periodically goes to Fastboot, but sometimes boots into the system, you can turn off the autoboot of this mode via ADB (Android Debug Bridge).

• 🖥️ Computer with Windows/Linux/macOS
• 🔌 USB-cable (preferably original)
• 📦 Installed drivers Xiaomi and ADB Tools

Instructions:

1. Turn on your smartphone to debug USB: Settings → About Phone → MIUI Version (click 7 times) Settings → Additional → For developers → Debugging by USB
2. Connect the Redmi Note 8T to your PC and confirm debugging permission.
3. Open the command prompt (cmd) and type: Adb devices Make sure the device is defined.
4. Fastboot: Adb shell settings put global fastboot_autoboot_disabled 1
5. Reboot your smartphone: adb reboot

If the problem persists after the reboot, try resetting the Fastboot settings to factory:

adb shell settings delete global fastboot_autoboot_disabled

💡

If ADB can’t see the device, try reinstalling drivers via the Mi Unlock Tool or using a USB 2.0 port (on some PCs, USB 3.0 doesn’t work well).

Method 3: Flashing through the Mi Flash Tool (if the smartphone is not turned on)

If the Redmi Note 8T is fixated on Fastboot and doesn’t respond to other methods, you just have to flash it through the official Mi Flash Tool, which is suitable even if:

• 🔴 The screen doesn't respond to touch.
• 🔄 The smartphone is constantly rebooting.
• ⚠️ Invalid Partition Table or No Command Error

Step-by-step:

1. Download the official firmware for Redmi Note 8T (select the Fastboot version, not Recovery!).
2. Unpack the archive into a folder without Cyrillic characters (e.g., C:\MIUI\).
3. Download and install the Mi Flash Tool.
4. Turn off your smartphone (press the Power + Volume Down for 20 seconds).
5. Hold Volume Down + Power and plug in USB-cable to PC – the device must be defined as Qualcomm HS-USB QDLoader 9008.
6. In Mi Flash Tool, click Select, specify the firmware folder, select Clean All mode and click Flash.

The process will take 5-10 minutes. Once completed, the smartphone will automatically restart in normal mode.
