How to use Xiaomi Bootloader Unlock Files: a complete guide to unlocking the bootloader

Introduction: Why unlock the bootloader on Xiaomi

Unlocking the bootloader unlock on Xiaomi smartphones is a must for anyone who wants to install custom firmware, get root rights or flash the device through Fastboot. Without this action, even official tools like the Mi Flash Tool will refuse to work with your device, giving an error about the locked bootloader.

The unlocking process requires special files β€” Xiaomi Bootloader Unlock Files, which include the Mi Unlock Tool utility, drivers and support scripts. However, many users face problems from the lack of an unlock button in the settings to errors like β€œCouldn’t” or β€œThis device is locked.” In this article, we will discuss the current 2026 unlock algorithm that works even for new models like Xiaomi 14 or Redmi Note 13 Pro+.

Unlocking without waiting 7/15 days: bypassing restrictions

  • 🌍 Link your device to your account via Mi Cloud in a region where there is no waiting time (such as India or Indonesia). VPN-server.
  • πŸ“± Buy a used phone with an already unlocked bootloader (checked by the fastboot oem device-info team - look for the line Device unlocked: true).

If you unlock your phone for sale, be sure to follow the command fastboot oem. clean_all After unlocking, this will delete all data of the previous owner, including the link to the Mi Account.

Important: Bypassing waiting through informal methods (for example, changing build.prop or using modified versions of the Mi Unlock Tool) can lead to the blocking of the Mi Account or the IMEI ban. Xiaomi actively fights against such methods, so taking risks is not recommended.

What to do after successful unblocking

Once unlocked, your Xiaomi is ready for further manipulation, but there are a few critical points to consider:

  1. Install custom recovery (for example, TWRP or OrangeFox) for backup and firmware ZIP-file.
  2. Squeeze Magisk for root rights (use the latest version from the official GitHub website).
  3. Turn off the automatic bootloader lock (on some firmware it turns on after updates). TWRP edit the file /vendor/build.prop, line ro.oem_unlock_support=1.

⚠️ Note: On devices with MediaTek processor (e.g. Redmi Note 12) 5G or POCO M5) Unlocking the bootloader can lead to loss of support for Widevine L1, Netflix and other services will only work in the future. 480p. Before unlocking, check the processor model in the application CPU-Z.

Unlocking the bootloader will void Xiaomi’s warranty. If you need to return the phone under warranty, pre-lock the bootloader back with the fastboot oem lock command (but this will result in a data reset!).
