However, it's important to note that unlocking the bootloader will erase all data on your device, so it's crucial to back up your data before proceeding.

To unlock the bootloader, you'll need to obtain an unlock code from Xiaomi's official website. The process involves creating a Mi account, if you haven't already, and then applying for the unlock code through the official Xiaomi website. Once you've received the unlock code, follow these steps to unlock the bootloader of your Xiaomi device:

Enable Developer Options: Go to 'Settings' and tap on 'About phone'. Find the 'MIUI version' and tap on it seven times to enable the 'Developer options'.
Enable OEM Unlocking: In 'Settings', go to 'Additional settings' > 'Developer options' and enable 'OEM unlocking'.
