Fastboot Mode on Xiaomi: A Complete User Guide

Have you ever faced a situation where a Xiaomi smartphone suddenly stops loading and a frozen logo with the inscription Fastboot appears on the screen? Or maybe you wanted to flash the device yourself but didn’t understand where to start? This mode is one of the most important tools for deep tuning and restoring Xiaomi phones, but many users fear it like fire because of the risk of “bricking” the device.

In fact, Fastboot is not a sentence, but a powerful tool that unlocks low-level smartphone functions, which can unlock a bootloader, flash custom software, restore a system after a crash, or even bring a dead machine back to life, but to use it, you need to understand clearly what it is, how it works and what pitfalls it poses. In this article, we will analyze everything from theory to practice, with a focus on the Xiaomi model 2020-2026.

What is Fastboot and Why You Need It on Xiaomi

Fastboot is a special protocol and mode of operation of Android devices that allows you to interact with the bootloader via a computer. Unlike the usual activation of a smartphone, when you log into Fastboot, the operating system does not boot, and control is transferred directly to the bootloader firmware.

On Xiaomi smartphones (including Redmi, POCO and Black Shark), this mode is used to:

• 🔓 Unlock the bootloader (mandatory step before firmware custom software).
• 📥 Install official and unofficial firmware via fastboot flash.
• 🛠️ System recovery after failure or “bricking".
• 🔄 Password reset (in some cases).
• 📡 Check the status of the device (for example, the unlock status).

It’s important to understand that Fastboot is not the same as Recovery.In Recovery, you can reset your settings or install it. ZIP-And Fastboot gives you access to the hardware at a deeper level, like you can reflash the boot or recovery section, which you can't do with a standard recovery menu.

How to Sign In to Fastboot on Xiaomi: All Ways

There are several ways to activate Fastboot on Xiaomi smartphones, depending on the state of the device.

Method 1: Through a button combination (if the phone is on)

The simplest method is:

1. Turn off your smartphone (if it is on).
2. Press and hold the power button + volume down button.
3. Hold them for 5-10 seconds until the screen with the hare in the hat-eared (Fastboot logo) appears.

Newer models (such as Xiaomi 13 or Redmi Note 12) can instead display a FASTBOOT sign on a black background, and if the screen doesn’t respond, try plugging the device into charging — sometimes it helps.

Method 2: Through the team ADB (if USB-debugging is on)

If you have USB debugging enabled and your phone is working, you can log in to Fastboot via the command:

adb reboot bootloader

This command will restart the device directly to the desired mode, convenient if the physical buttons do not work.

Method 3: Forced entry (if the phone doesn't respond)

If the Xiaomi smartphone is “hang” on the logo or does not turn on, try:

1. Connect the device to the PC via USB.
2. Press the power button for 20-30 seconds (sometimes helps to "knock" it out of the getting stuck state).
3. If it doesn’t work, try the power + volume up + volume down (on some models).

💡

On Qualcomm Snapdragon models (like the POCO F5 or Redmi K60), the forced entry into the Fastboot is sometimes helped by shorting the TEST POINT contacts on the motherboard.

How Fastboot on Xiaomi is Different from Recovery

Many people confuse Fastboot and Recovery, but these are two fundamentally different modes.

The critical difference is that in Fastboot you work with raw partitions (e.g. mmcblk0p1), while in Recovery you work with files and folders (/system, /data). This means that a bug in Fastboot can lead to loss of access to the entire device, whereas in Recovery you can usually fix the situation by flashing it.

The main Fastboot commands for Xiaomi: cheat sheet

To control a device in Fastboot mode, commands are used via the terminal (or Mi Flash Tool).

• 🔍 fastboot devices – check the connection of the device (serial number should be displayed).
• 📋 fastboot getvar all – output of information about the device (model, bootloader status, etc.).
• 🔓 fastboot oem unlock – unlock the bootloader (requires confirmation on the phone).
• 📥 fastboot flash [section] [file.img] — firmware of a particular partition (e.g., fastboot flash boot) magisk_patched.img).
• 🗑️ fastboot erase [section] — partition cleanup (e.g., fastboot erase userdata for data resetting).
• 🔄 fastboot reboot – reboot to normal mode.
• 🛠️ Fastboot Reboot Recovery – Reboot Recovery.

Unlocking the bootloader through Fastboot: step-by-step instructions

On Xiaomi smartphones, the bootloader is locked by default, and to flash custom software or get root rights, you have to unlock it. Here's how to do it through Fastboot:

Step 1: Preparation

2. Enable USB debugging and OEM unlocking in Settings → About Phone → MIUI version (tap 7 times to open the developer menu).

4. Press Unlock and wait until it is completed (usually takes 3-5 minutes).

Attention! Once unlocked, Xiaomi may block the ability to re-unblock for 7 to 30 days (depending on the model), and some banking applications (e.g. SberBank Online) may stop working due to the SafetyNet trigger.
