Fastboot on Xiaomi: How to enable and use the mode correctly

Fastboot mode on Xiaomi smartphones (including the Redmi and POCO lines) is a special engineering mode that allows you to perform low-level operations with the device, from unlocking the bootloader to firmware custom recovery. Without it, you can not install alternative software, get root rights or restore the brick after a failed update. However, many users face difficulties when trying to enter this mode — especially on new models with MIUI 14/15 and Anti-Rollback protection.

In this article, we will discuss all the current ways to enable Fastboot on Xiaomi devices (including Redmi Note 12 Pro+, POCO F5, Xiaomi 13T and others), explain the differences between Fastboot and Recovery, and warn against typical errors that can turn your smartphone into a “brick”.

What is Fastboot and Why You Need It on Xiaomi

Fastboot (or bootloader mode) is a protocol for interacting with the bootloader of an Android device via a bootloader. USB-Unlike the usual Recovery Mode, where basic functions (reset, update) are available, Fastboot allows you to connect to a PC:

• 🔓 Unlock the bootloader (a mandatory step for installing custom firmware or root).
• 📥 Sweep official/unofficial images (including fastboot) ROM and TWRP).
• 🛠️ Restore the bricks after unsuccessful manipulation of the system.
• 🔧 Change partition markup (for example, to install) GSI-firmware).

On Xiaomi, Fastboot is often confused with EDL Mode (Emergency mode for firmware through Qualcomm tools), but these are different things: Fastboot runs at the Android bootloader level, and EDL runs at the processor level. Most users only need the first.

⚠️ Note: On Xiaomi models with MediaTek processors (e.g. Redmi) 12C, POCO M6 Pro) some Fastboot commands may be blocked by the manufacturer, in which case switching to the BROM Mode (analogue) EDL for MTK).

Official and unofficial ways to log in to Fastboot

There are 4 main methods for activating Fastboot mode on Xiaomi smartphones, their choice depends on the state of the device (on / off), the version of MIUI and the presence of root rights.

1. Standard key combination (for switched off phone)

This is the most common method, which works on 90% of models (except for some new devices with MIUI 15).

Turn off your smartphone (hold the power button for 10 seconds).

Press the Power button + Volume down at the same time.

Hold for 5-10 seconds until the Fastboot logo appears.

Connect your phone to your PC through USB (if required).-->

On some models (e.g. Xiaomi 13 Ultra or POCO F5 Pro), the combination may differ:

• 📱 Redmi Note 12 Pro+: Nutrition + Loudness up + Loudness down (hold 15 seconds).
• 📱 Xiaomi Pad 6: Powering + Volume down (but you need to turn off charging first!).

⚠️ Note: If the phone vibrates and turns on in normal mode after holding the keys, then the bootloader is locked (typical for devices with Anti-Rollback 4).+). This will require you to unlock through the Mi Unlock Tool.

2. Entrance through ADB (if the phone is on)

If your smartphone is working but you need to switch to Fastboot without turning it off (for example, for firmware), use the ADB command:

adb reboot bootloader

Preconditions:

• 🔌 Debugging is on. USB (Settings → The phone. → Version. MIUI (7 times to tap) → Additional settings → For developers → Debugging by USB).
• 🖥️ Drivers installed ADB/Fastboot on PC (download from the official Android website).
• 🔒 Permitted. USB-Connection in the developer settings (Debugging by USB (safety)).

💡

If the adb reboot bootloader command doesn’t work, try adb kill-server first, then adb start-server and try again.

3. Automatic login when connected to a PC (to unlock)

On some models (for example, Redmi K60 or Xiaomi 12T) Fastboot mode is activated automatically when you connect to a PC running Mi Unlock Tool.

1. Turn off the phone.
2. Connect it to the PC via USB.
3. Press the Volume down for 3-5 seconds.

If the drivers are installed correctly, Android Bootloader Interface will appear in Device Manager.

4. Alternative methods (for locked devices)

If standard methods don’t work (for example, due to an Anti-Rollback or a damaged bootloader), try:

• 🔄 Hard reset via Recovery, then login to Fastboot.
• 🔌 Use of the test item (on some models: Settings) → Memory. → Three points. → Reboot to Fastboot).
• 🛠️ Crossing the EDL (Requires an authorized Xiaomi account and Deep Flash cable).

The difference between Fastboot and Recovery on Xiaomi

Many users confuse Fastboot and Recovery, although they are fundamentally different modes.

For example, to install TWRP, you first need to unlock the bootloader through Fastboot, and then flash the recovery image through Fastboot or TWRP itself.

💡

If you just need to reset or update your firmware, use Recovery. Only Fastboot is available to unlock, firmware, or restore the brick.

Step-by-step: how to flash the device through Fastboot

Suppose you have successfully entered Fastboot mode and want to flash an official fastboot-ROM (for example, to recover from a crash).

1. Preparation of PCs and files

• 📥 Download the official firmware for your model from the site MIUI Downloads (select the Fastboot version instead of Recovery!).
• 📂 Unpack the archive in a folder. C:\platform-tools\ (fixed ADB/Fastboot).
• 🔌 Connect your phone in Fastboot mode to your PC.

2. Connection check

Open the Command Prompt in the firmware folder and do:

fastboot devices

If the device is determined (the serial number will appear), you can continue. If not, check the drivers or cable.

3. Launching firmware

For the official fastboot-ROM firmware, use the script:

• 📜 For Windows: Launch the file flash_all.bat.
• 🐧 For Linux/Mac:./flash_all.sh.

For selective firmware (e.g. boot.img only):

fastboot flash boot boot.img


fastboot reboot

⚠️ Note: On models with Dynamic Partition (e.g. Xiaomi) 12/13 standard series flash_all.bat This requires manual partitioning through the fastboot update command.

Typical errors and their solution

When using Fastboot, users often encounter errors, and here are the most common ways to fix them:

If you see the message This device is locked, then the bootloader is locked, and it must be unlocked through the Mi Unlock Tool (requires a Xiaomi account binding and waiting 7-360 hours).

How to avoid Xiaomi becoming a brick

Fastboot is always risky, and here are 5 rules to avoid fatal mistakes:

• 🔋 The battery must be at least 50 percent charged, and the interruption of the firmware due to discharge almost always leads to a brick".
• 🔗 Use the original cable (better from the kit). Cheap cables can interrupt data transmission.
• 📋 Check the firmware version for compatibility with Anti-Rollback (information is available on Xiaomi Firmware Updater).
• 🚫 Do not interrupt the firmware process (even if it is 99% frozen, wait 10-15 minutes).
• 🔄 Create a backup of important data before any manipulation (Fastboot has closed access to user files!).

If the phone doesn’t turn on after firmware (black screen, vibration), try:

1. Log into Fastboot and repeat the firmware.
2. Use the Mi Flash Tool in Clean All mode (erase all data!).
3. Contact the service center (if the loader is damaged).

💡

If you are not sure about your actions, use official tools (Mi Flash Tool, Mi Unlock) and firmware from the Xiaomi site. Custom solutions increase the risk of "bricking" by 3-5 times.
