Xiaomi Mi Unlock Tool v6.5.224.28 (Latest) – Official Bootloader Unlock Tool
Rooting a Xiaomi phone, flashing a custom recovery, or installing a third-party ROM all start at the same place — the bootloader. The Xiaomi Mi Unlock Tool is the official desktop utility from Xiaomi that handles bootloader unlocking on all Xiaomi, Redmi, and POCO smartphones. Without unlocking the bootloader first, none of those Android repair or customization tasks are possible. This guide covers everything you need — what the tool does, prerequisites, step-by-step usage, and the direct free download for Windows PC.
What Is Xiaomi Mi Unlock Tool?
Xiaomi Mi Unlock Tool (also known as MiFlash Unlock) is the official bootloader unlock utility developed and distributed by Xiaomi Inc. It runs on Windows PC and lets you unlock the bootloader on Xiaomi, Redmi, and POCO Android devices through a straightforward desktop interface.
Unlocking the bootloader is the essential first step before you can root your device with Magisk, flash a custom recovery like TWRP, or install modified firmware such as Xiaomi.eu or any custom AOSP ROM. The tool communicates directly with Xiaomi’s cloud servers to verify your Mi Account authorization before completing the unlock — which means your Mi Account must be linked to the device before you start.
For devices running Xiaomi HyperOS (including HyperOS 2.0 and HyperOS 3.0), you must first request and receive unlock authorization through the official Xiaomi Community App on your phone before using the desktop tool. Once your account gets approved, the desktop tool finalizes the process.
One important thing to know upfront: the unlock process performs a complete factory reset on your device. Back up all your data before you proceed.

Prerequisites Before You Start
Complete these steps on your phone before running the desktop tool. Skipping any of these will cause the unlock to fail.
On Your Phone:
- Enable Developer Options — Go to Settings → About Phone and tap on your MIUI or HyperOS version number 7 times until Developer Options are enabled.
- Enable OEM Unlocking — Go to Settings → Additional Settings → Developer Options and turn on OEM Unlocking.
- Bind Your Mi Account — In the same Developer Options menu, tap Mi Unlock Status and link your active Mi Account to the device hardware. This step is mandatory — the desktop tool checks this binding.
- Back Up Your Data — The unlock process will wipe your device completely. Transfer all photos, contacts, and app data to a safe location before proceeding.
On Your PC:
- Install USB Drivers — Make sure your PC has working Xiaomi USB Fastboot drivers installed. Without the correct driver, the tool will not detect the device. You can use the Qualcomm USB Driver or MTK USB Driver depending on your device chipset.
