This binary requires Python 2.7 or newer installed on your system.
It currently supports Windows x86/x64, Linux x86/x64 & arm/arm64 architectures.
img2sdat.py <system_img> [-o outdir] [-v version] [-p prefix]
<system_img>= input system image[-o outdir]= output directory (current directory by default)[-v version]= transfer list version number (1 - 5.0, 2 - 5.1, 3 - 6.0, 4 - 7.0, will be asked by default, more info on xda thread)[-p prefix]= name of image (prefix.new.dat)
This is a simple example on a Linux system:
~$ ./img2sdat.py system.img -o tmp -v 4
It will create files system.new.dat, system.patch.dat, system.transfer.list in directory tmp.
