How to turn off Fastboot on Xiaomi Redmi 8: 5 working ways

Fastboot mode on Xiaomi smartphones is a special diagnostic mode that is used to firmware, unlock the bootloader or restore the system. However, sometimes Redmi 8 can “hang” in it after a failed update, reset settings or accidentally pressing a combination of buttons. If your device’s screen is burning black with the words FASTBOOT and the logo of the rabbit in the hat-eared, do not panic: there is a way out.

In this article, we’ll look at all the ways you can disable Fastboot, from the elementary (button reboot) to the advanced (ADB commands and flashing through Mi Flash). We’ll focus on the reasons for getting into this mode and how to avoid repeated crashes. If your Redmi 8 doesn’t respond to presses or cyclically reboots, here’s the solution.

⚠️ Important: If your smartphone is on the Fastboot after trying to unlock the bootloader or install custom firmware, some methods can lead to complete data loss. In this case, we recommend first trying the soft methods (sections 2–3), and then moving to the radical ones (sections 4–5).

1.What is Fastboot and why does Redmi 8 get into it?

Fastboot mode (not to be confused with Bootloader!) is a low-level smartphone state where commands are available to work with partitions, the kernel and the bootloader.

  • 🔧 Forced – through a combination of power buttons + Loudness down (hold 10-15 seconds).
  • 📱 Automatically – if the system cannot load recovery or the main OS (for example, after resetting to factory settings).
  • 🔄 If the firmware fails – if the update file is corrupted or incompatible with the version MIUI.
  • 🔓 After unlocking the bootloader - some versions MIUI Require confirmation via Fastboot.

On Redmi 8 (codenamed olive), this mode is often triggered accidentally because of a faulty power button or if the user tries to log in to Recovery but holds the keys for too long.Visually it differs from Recovery Mode by a black screen with white FASTBOOT and the Mi Bunny icon in the upper left corner.

⚠️ Note: If your Redmi 8 loads into the Fastboot after each shutdown, it is a sign of damage to the boot or system partition).

📊 How often does your Xiaomi boot up spontaneously to Fastboot?
Never.
Sometimes (1 time per month)
Frequently (once a week)
Constantly (on each switch off)

2. Method 1: Reboot buttons (the easiest method)

If your smartphone just hangs in the Fastboot after accidentally hitting or crashing, try the standard reboot, which works 90% of the time and doesn’t require a PC connection.

  1. Hold the Power button for 20-30 seconds until the screen goes out.
  2. If the device doesn’t respond, press and hold the combination: Power + Volume Up Hold it for 10-15 seconds until you feel the vibration or see the Redmi logo.
  3. If the smartphone is loaded again in Fastboot, repeat step 2, but hold the buttons for up to 30 seconds.

💡 Why does it work? Prolonged power button retention mimics a hardware reset that forcibly interrupts the current mode. On Redmi 8, this works even when the buttons stick.

Method 2: Exit via MIUI (if the system is booting)

If after rebooting the buttons, the smartphone still starts in normal mode, but periodically “leaves” to Fastboot, the problem may be in the MIUI settings.
