Why you need ADB and Fastboot for Xiaomi devices
ADB (Android Debug Bridge) and Fastboot are bridges between your computer and Xiaomi smartphone, allowing you to perform operations that are not available through the standard interface. From unlocking the bootloader to installing custom firmware, these utilities open access to the heart of the device, but without the right setup, they are useless or even dangerous.
Many users face problems when they first run: the device is not detected, commands are not executed, and dozens of contradictory instructions on the Internet. This article will help avoid typical errors and teach you how to connect Xiaomi to the Internet correctly.

Before connecting to your computer, you need to activate the hidden developer settings and enable debugging. The instruction is universal for all devices on MIUI 12/13/14, but may differ slightly for older versions (up to MIUI 11).
- Open Settings → About your phone and tap 7 times on the MIUI version until the notification “You became a developer” appears.
- Return to the main settings menu and select Additional → For developers.
- Activate the switches: 🔄 Debugging by USB (main) 🔒 Unlocking OEM (required to unlock the loader) 📶 Debugging over Wi-Fi (optional, for wireless connection)
Allow debugging over USB
For HyperOS devices (such as Xiaomi 14 or Redmi K70), the path to developer settings may be different: Settings → About Phone → HyperOS version (stamp here).
Installation of Xiaomi ADB Fastboot Tools on Windows, macOS and Linux
The installation process depends on the operating system, and we will look at official methods without using "packed" repacks, which often contain outdated versions of utilities.
For Windows 10/11

- Unpack the archive in the root of the C:\platform-tools drive (the path without spaces!).
- Install the drivers: 🖥️ For Xiaomi, download Mi. PC Suite – it will automatically install the desired drivers. 🔧 Manual: through Device Manager, update the driver for the device with an exclamation mark, specifying the folder C:\platform-tools\usb_driver.
PATH
This computer → Properties → Additional system parameters → Environment variables
In System Variables, find PATH → Change → Add → C:\platform-toolsFor macOS/Linux
On Unix systems, the process is simpler:
Installation via Homebrew (macOS)
brew install android-platform-tools
Installation via package manager (Ubuntu/Debian)
sudo apt update && sudo apt install adb fastbootAfter installation, check the performance of the team:
adb versionVersion 1.0.41 or later (for 2026) should be displayed.

Solving Common Errors When Working with ADB/Fastboot
Even when you set it up properly, users are going to have errors, and we've collected the most common problems and their solutions.
| Mistake. | Reason. | Decision |
|---|---|---|
| device unauthorized (in ADB) | No permission to debug on the phone has been confirmed. | Turn off/connect the cable and confirm the request on the device. If it doesn't appear, check the developer's settings. |
| waiting for device | Drivers are not installed or the device is not in Fastboot/ADB mode. | Check Device Manager for unknown devices. Reinstall the driver. |
| FAILED (remote: 'Flashing is not allowed') | The bootloader is locked. | Unlock the bootloader through the Mi Unlock Tool (see previous section). |
| error: no devices/emulators found | No device found. | Try another cable/port. Linux/macOS may need to add udev rules. |
For invalid sparse file format at header errors when running through Fastboot:
- 📥 Download the firmware again – the file may have been corrupted when downloaded.
- 🔄 Use the command fastboot flash all -w instead of fastboot flash all (key) -w format).
- 🛠️ For older devices (e.g., Redmi) 4X) You may need to use MiFlash in Clean All mode.
💡
If the device stopped turning on after a failed firmware ("brick"), do not try to re-swipe it through the Fastboot. Use EDL mode (via testpoints or authorized cable) is the only way to restore 90% of the time.
