Tizen T-KTS firmware research: mapping the VDFS4 filesystem

Tizen T-KTS firmware research maps the VDFS4 filesystem inside a decrypted Samsung smart TV firmware image. Its notes describe superblocks, catalog records, file extents and copy-on-write block translation, while Python tools enumerate entries and locate file data. The author reports 2,113 enumerated entries; payload decompression remains unresolved.
