If you have a generic white box with no brand name, you need to check the hardware info.

Firmware is the software that controls your TV box's hardware and provides the interface for you to interact with. Rockchip TV box firmware is specifically designed for Rockchip-powered devices and is responsible for managing the device's functions, including video playback, network connectivity, and app support.

Rockchip firmware usually consists of a specific file structure (often ending in .img ) that contains the bootloader, the kernel, and the system partition. Because Rockchip is so customizable, manufacturers ranging from high-end brands like NVIDIA (Shield) and Xiaomi to generic "no-name" brands use these chips.
