How to get into Fastboot on Xiaomi: all the ways and nuances

Fastboot mode on Xiaomi devices is a special state that allows you to perform low-level operations: unlock the bootloader, firmware through the Mi Flash Tool, recovery from crashes or even a complete reset to factory settings. Without this mode, you can not install custom software, get root rights or fix a critical error when the smartphone does not boot in normal mode.

However, logging into Fastboot on Redmi, POCO or Mi has its own peculiarities – from button combinations to using commands through ADB. In this article, we will analyze all the current methods (including those that work on new models with HyperOS), as well as explain how to avoid typical errors, for example, when the device is not defined by the computer or hangs on the Mi logo. If you have never worked with Fastboot, start with the first section – there is an explanation of why it is needed and when to use it.

What is Fastboot and Why You Need It on Xiaomi

Fastboot mode (not to be confused with Recovery!) is a protocol that allows you to interact with the bootloader of the device through a computer. Unlike conventional on, here the smartphone does not load the operating system, but waits for commands from the user or software like the Mi Flash Tool.

The main tasks for which Fastboot is needed are:

• 🔓 Unlocking the bootloader (mandatory step before firmware custom software).
• 📥 Installation of official or custom firmware through fastboot flash.
• 🔄 Recovery after the “brick” (when the smartphone does not turn on).
• 🛠️ Resetting protection (for example, if the pattern lock is forgotten).
• 📡 Check the status of the bootloader by the fastboot oem device-info command.

It’s important to understand that Fastboot is not the same as EDL Mode (Emergency Mode for Firmware via Qualcomm). The former is available to the user, the latter requires special hardware or vulnerabilities. Also don’t confuse it with Recovery – there are other features (for example, reset via Wipe Data).

⚠️ Attention: On new Xiaomi models 13/14, Redmi Note 12/13 and POCO F5/X5 With HyperOS, some Fastboot commands may be blocked by the manufacturer!

Method 1: Sign in to Fastboot via hardware buttons (for all models)

The most versatile method, which works even if the smartphone is not turned on or locked, is suitable for Xiaomi, Redmi and POCO of all generations, including the old models on the MIUI 8-12 and the new ones with HyperOS.

Instructions:

1. Turn off the device (if it is getting stuck – press the power button for 10-15 seconds).
2. Hold it together: 🔽 The volume button (Volume Down) 🔄 Power button (Power)

10-15 seconds

FASTBOOT

On some models (such as the Redmi 9A or POCO M3), you may need to first clamp Volume Down and then Power. If nothing happens, try an alternative combination: Volume Up + Power (but this usually leads to Recovery).

If the smartphone does not respond to the buttons, the following reasons are possible:

• 🔋 Battery discharged (minimum 30% charge required to log into Fastboot).
• 🔌 Sticking buttons (try moving them or blowing them from dust).
• 🛠️ Hardware malfunction (for example, damaged button plume).

Method 2: Sign in via ADB (if smartphone is enabled)

If the device is working, but you need to upgrade to Fastboot without rebooting (for example, to unlock the bootloader), it is more convenient to use the ADB command.

1. Enable USB Debugging in Settings → About Phone → MIUI Version (click 7 times to become a developer) → Additional → For Developers → Debugging over USB.
2. Connect your smartphone to your computer via the original cable (important!).
3. Open the Command Prompt (Windows) or Terminal (macOS/Linux) in the folder with ADB.
4. Enter the command: adb reboot bootloader

Once the command is executed, the device will automatically restart to Fastboot. If you request debugging permission, confirm it on your smartphone screen.

⚠️ Attention: HyperOS has changed the way to customize the developer! → The phone. → Device information → Build number (click 7 times) and then search for Developers in the main settings menu.

If the adb reboot bootloader command is not working, check:

• 🔌 Cable and port USB (Try another cable or port on your PC).
• 🖥️ Drivers (install Mi) USB Driver or Google USB Driver).
• 🔄 Version ADB (Update platform-tools via Android SDK).

If ADB doesn’t see the device, try entering the command adb kill-server and then adb start-server before trying again.

Method 3: Automatic login when connected to a PC (for firmware)

Some tools (such as the Mi Flash Tool or XiaomiTool V2) automatically transfer the device to Fastboot when you connect to your computer.

How it works:

1. Turn off your smartphone.
2. Connect it to the PC via USB-cable.
3. Press Volume Down + Power for 5-7 seconds (as in Method 1).
4. Open the Mi Flash Tool – the program must determine the device in Fastboot mode.

If the Mi Flash Tool doesn't see the smartphone:

On models with a MediaTek processor (such as the Redmi 10C or POCO M4 Pro), a special version of the Mi Flash Tool with MTK support may be required to run through Fastboot.

Fastboot vs EDL Mode: What’s the difference and when to use what?

Many people confuse Fastboot with EDL Mode (Emergency Download Mode), but these are two different modes with different features:

When to use EDL Mode:

• 🚨 The smartphone is not included even in the Fastboot (full "brick").
• 🔧 You need to flash persist or other protected partitions.
• 📱 Device with Qualcomm processor and locked bootloader (for example, after a failed firmware).

Fastboot is 90 percent good, but if you're faced with a Remote error: oem unlock is not allowed, or your smartphone doesn't respond to any commands, you can't do without EDL, but it often requires special hardware or paid service centers to enter this mode.

💡

If your goal is to unlock the bootloader or install the official firmware, start with Fastboot. EDL Mode is only needed in critical cases when other methods do not work.
