- Connection Sequence: Ensure your phone is completely powered down. Press and hold both Volume Up + Volume Down buttons, and connect the USB cable to your PC.
- Writing Progress: The tool will detect the device. A brief red status line will appear, followed by a yellow progress bar indicating the data writing phase. You may release the volume keys once the yellow bar initiates.
- Completion Prompt: Keep the connection stable until the tool displays a confirmation modal with a green check-mark reading "Download OK".
- Reboot: Safely disconnect the USB cable, perform a battery pull (if possible), and power on the device. The initial system configuration may require 5–10 minutes to finish.
