Chinese-language guide to the software upgrade procedure for network smart TVs built on the MSD6A338 platform, packed in a 462 KB zip. MSD6A338 is a MStar TV SoC used in many Android-based LCD TV boards. The guide describes how to load the firmware update, typically from a USB drive or through a serial or programmer method. It contains instructions rather than the firmware itself. Read the steps carefully and match the board and panel before flashing any image you obtain separately.
