I would like to extract userdata.img which is one of the firmware files complied under Android platform.
You can see what I have tried below:
benjamin@benjamin-virtual-machine:/GPL/tmp/userdata$ file userdata.img
userdata.img: VMS Alpha executable
benjamin@benjamin-virtual-machine:/GPL/tmp/userdata$ /GPL/unyaffs-master/unyaffs userdata.img
Can't determine flash layout, perhaps not a yaffs2 image
as for this situation, how to deal with it? Are there any other methods?
Any reply will be appreciated.
