Project description
Jefferson
JFFS2 filesystem extraction tool.
Installation
You can install Jefferson from PyPi with the following command:
pip install --user jefferson
Usage
jefferson filesystem.img -d outdir
Features
- big-endian and little-endian support with auto-detection
- zlib, rtime, LZMA, and LZO compression support
- CRC checks - for now only enforced on
hdr_crc - extraction of symlinks, directories, files, and device nodes
- detection/handling of duplicate inode numbers. Occurs if multiple JFFS2 filesystems are found in one file and causes
jeffersonto treat segments as separate filesystems
