Extracting the boot image and system partitions serves several practical purposes:

Connect the TV to a PC using the appropriate cable (USB, HDMI-to-UART, or VGA-to-UART).

Run the extraction software and select the correct chipset profile.

Access the TV's hidden "Pro" or "Service" menu to enable USB debugging or UART output.

For most users, these tools are best used as a last resort for repair or as a gateway into the world of TV software customization. Always cross-reference your TV's model number and chipset before attempting to use any extraction utility.
