8. Connect your phone to the PC using a USB cable.
9. Click Unlock in the Mi Unlock app on your PC.

Step 2: Downloading the Correct Fastboot ROM

3. Save the ROM to your computer for easy access.

Step 3: Flashing the Fastboot ROM

Prepare Xiaomi Flash Tool

Download and install the Xiaomi Flash Tool on your Windows PC. Launch the tool and install the necessary drivers as prompted.

Enter Fastboot Mode
