This paper explores the technical intricacies of modifying and repacking firmware for Android TV devices built on the MStar (MStar Semiconductor, now part of MediaTek) chipset architecture. It details the specific partition layout, the proprietary boot header structures used by MStar, and the ecosystem of tools required to successfully unpack, modify, and repack firmware images. The focus is on the "MStar Upgrade" (MUG) format and the tools necessary to maintain header integrity during the repacking process.

Most Mstar firmware updates come as a single .pkg file (e.g., update_msd638.pkg ). This is a standard Android system.img . Instead, it is a proprietary Mstar container that holds:
