Sony Corporation distributes firmware updates for its television line (BRAVIA, Android TV, and Google TV platforms) via two primary methods: over-the-air (OTA) and manual USB drive installation. While OTA is convenient, the USB method remains critical for recovery from boot loops, network constraints, and pre-release deployment. This paper examines the technical specifications for the USB update process, including file system formats (FAT32/exFAT), directory structure (SONY_BRAVIA_UPDATE_XXXXX), cryptographic signature verification, and common failure modes (e.g., incorrect partition alignment, non-standard volume labels). We conclude with a step-by-step diagnostic protocol for engineers and advanced users.
