Fastboot mode on Xiaomi: why the smartphone has got stuck and how to bring it

Did you turn on Xiaomi, and instead of the usual desktop, a black background appeared with a green robot and the words FASTBOOT? Or did the phone suddenly reboot into this mode after the update? Don't panic - this is not a breakdown, but a service mode that is used to firmware, unlock the bootloader or restore the system, 90% of the time the problem is solved without going to the service center.

In this article, we will discuss all possible reasons for getting into Fastboot on Xiaomi, Redmi and POCO, as well as give step-by-step instructions for exiting the mode - from the simplest restart to flashing through the Mi Flash Tool.

What is Fastboot Mode and Why Does the Smartphone Get Into It?

Fastboot Mode (or Bootloader Mode) is a low-level interface for interacting with the hardware of a smartphone. It is activated before Android boots, allowing you to:

• 🔧 Install custom firmware (Custom) ROM)
• 🔓 Unlock the bootloader (Bootloader Unlock)
• 📥 Restore official software through the Mi Flash Tool
• 🔄 Perform a reset to factory settings if the system is not booting

However, sometimes Xiaomi spontaneously switches to Fastboot without user commands.

• ⚡ Failed update (interrupted or with error)
• 🔋 Battery discharge (less than 20% when trying firmware)
• 🛠️ Damaged system files (due to viruses or root rights)
• 🔌 Hardware failure (damaged connector) USB power-button)
• 📱 Firmware conflict (for example, after rollback to the old version) MIUI)

If your smartphone has been stuck in the Fastboot after manipulating the firmware, it is likely a software problem, but if the mode was activated without your participation (for example, after a fall or moisture), this may indicate a hardware malfunction.
