# 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.

## Requirements & limits

- **Prerequisites:** An official T-KTSDEUC firmware image must be obtained and decrypted separately.
- **Limits:** The tools use paths and offsets measured from one decrypted platform.img; other firmware versions need adjustment.
- **Limits:** File payload decompression is incomplete.
- **License:** MIT license.
