jefferson

JFFS2 filesystem extraction tool

This is a slightly modified version of the original work with fixes for better error handling

Installation

Just install the dependencies, clone or extract the project, browse to src folder and run jefferson

Dependencies

• cstruct
• pyliblzma

$ sudo pip install cstruct
$ sudo apt-get install python-lzma

Features

• Big/Little Endian support
• JFFS2_COMPR_ZLIB, JFFS2_COMPR_RTIME, and JFFS2_COMPR_LZMA 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 jefferson to treat segments as separate filesystems

Usage

$ jefferson filesystem.img -d outdir
