  • Make sure both the Mi Accounts are same in device and in unlock tool
  • If you are new user and never applied for unlocking before, in step 1 it will take you to the page for username creation and then you can fill in the details and proceed.
  • Do note that unlocking bootloader will erase user data
  • You can only unlock your own device. One Mi account can only unlock one device in 30 days
  • Make sure your PC has necessary drivers and you're on official MIUI ROM before you start to unlock, download and install latest Mi PC Suite & Mi Flash
  • After the device is unlocked, it becomes less secure and more vulnerable to malware attacks, which may lead to the disclosure and loss of your private data. Some features which require high security level (e.g., Find device, added-value services, etc.) will no longer be available. You are recommended to lock the bootloader after flashing the ROM via Fastboot mode for better security.
