Unlocking the bootloader is the first and most important step for those who want to gain full control of their Xiaomi, Redmi or POCO device. It is Bootloader that checks the integrity of the operating system before launch, and unlocking it opens the door to install custom recavators, obtaining root rights and reflashing to global versions of MIUI. However, the process of entering this mode often raises questions for beginners, especially when standard methods do not work or the computer does not see the smartphone.
In this article, we will discuss in detail all possible ways to go to Fastboot mode, since it is through it that you interact with the PC. You will learn how to prepare the device, what drivers are necessary and what to do if the on button does not respond properly. Understanding these nuances will save you hours of troubleshooting and save you from accidental errors.
It is worth noting that logging into Bootloader is a technical procedure that requires care. While logging into Fastboot mode is data-safe by itself, further manipulation can lead to loss of information. So make sure to make a full backup of all important data before starting any actions, since unlocking the bootloader on Xiaomi devices automatically performs a full reset (Wipe Data).
Preparing a smartphone and computer for work
Before you try to enter bootloader mode, you need to make sure that your device and computer are ready to interact. USB-A cable that supports data transfer, not just charging. Cheap cables from power-bank often don't have the necessary contacts to transmit signals, which will result in the computer simply not seeing the phone.
It is also critical to install the right drivers. Xiaomi devices usually require Qualcomm HS-USB QDLoader or Android Bootloader Interface drivers. If you are using Windows 10 or 11, the system often tries to install them automatically, but sometimes this process is not correct, in which case it is recommended to download the official Mi Unlock Tool package, which will offer to install the necessary components when you first try to run.
⚠️ Warning: Before entering Bootloader, make sure that the battery is at least 50-60%. Abrupt power outage during firmware or unlock procedures can cause permanent damage to the software.
Don't forget to turn on the debugging. USB in the developer menu, although this is not always required for the login to Fastboot, but for subsequent actions with the help of the user. ADB-In order to activate the developer menu, you need to click on the build number several times in the About Phone section».
☑️ Check before entering the Bootloader
Standard method of entering through a combination of buttons
The most common and reliable way to get into Fastboot mode on Xiaomi smartphones is to use a physical button combination, which works on most models, from the old Redmi Note to the latest flagships of the Xiaomi 14 series.
Turn off your smartphone completely. Make sure the screen is off and the device is not making any noise. Then press the Volume Down button and, without letting go, plug it in. USB-And the second end of the cable is already inserted into the computer, and the Fastboot logo, which shows a rabbit fixing an android, or something like this, should appear on the screen"FASTBOOT" orange.
- 🔌 Connect the cable to your PC in advance to keep the button free.
- 📉 Press the Volume Down button before connecting the cable.
- 🐇 Hold the button until the Fastboot logo appears.
- 💻 The computer must make the sound of the connection of the new device.
If your phone just turned on instead of a Fastboot, you've pressed the button too late or let it go too early. Try repeating the procedure by holding the volume button even tighter when you plug in the cable. On some models with a side button (a fingerprint scanner), it's important not to confuse the buttons.
💡
If the standard combination does not work, try to press the volume button and connect the cable to the phone turned off, and only then press the on button once, without releasing the volume.
Using ADB commands to move to Fastboot
If the physical buttons are damaged or stuck, or the phone goes into an endless bootloop, software techniques come to the rescue. You'll need an ADB installed on your computer, which allows you to send low-level commands directly to the Android system.
First, make sure that the Developer menu includes USB Debugging. Connect your phone to your PC in normal operating mode. Open the Command Prompt (CMD) or PowerShell in the ADB folder and enter a command to check the connection:
adb devicesIf you have a serial number on the list, you've got the connection, you can send a command to reboot to bootloader mode.
adb reboot bootloaderAfter pressing Enter, the smartphone will immediately restart and must enter Fastboot mode.This method is especially useful when the phone screen is not working, but the system inside is functioning, and you can “touch” the permission to debug.
⚠️ Attention: Team `adb reboot bootloader` It only works if the phone is booted into Android, if the device is in a "brick state," or EDL The regime, this command will not be carried out.
Table of codes and features for different models
Different models of Xiaomi, Redmi and POCO devices may have small nuances in the behavior when entering bootloader mode. Below is a summary table that will help you navigate depending on the series of your device.

|---|---|---|---|
| Xiaomi (Mi) series | Vol- + USB | Classical method | The android hare |

| Xiaomi 11/12/13/14 | Vol- + USB | Sensitive to cable. | Mi + Fastboot logo |
| Devices with an AI button | Vol- + USB | Not to be confused with Google Assistant | Text menu |
It's important to understand that the key element here is the volume button. Unlike Recovery Mode, which uses a combination of a power button and a volume button, Bootloader only needs one volume button, and if you're on the Recovery menu, you've either had a volume button or a power button pressed.
To exit Fastboot mode without connecting to your computer, you can just press the power button and hold it for about 10-15 seconds. The device will forcefully restart. If you plan to unlock the bootloader, just rebooting won't help, you need to use Mi Unlock.
Problem Solving: The computer cannot see the device
One of the most common problems is that the phone has entered Fastboot mode, but Windows Device Manager displays an unknown device or device with an error, which means that the operating system cannot find the right driver to communicate with the bootloader.
In the Device Manager, look for Portable Devices, Outer Devices, or Android Device if you see a device with a yellow exclamation mark or name"QHSUSB_BULK" (mode EDL) or "Android", you need to update the driver manually. Right-click, select "Update driver" →"Select a driver from the list of available drivers on your computer".
