For academic/forensic reasons I want to get an image from my SmartPhone and study it. The File System is YAFFS2. From adb shell and using 'cat proc/mtd' I can see that I have for partitions: system,appslog,cache,userdata. I can get the four images using dd command, like 'dd if=/dev/mtd/mtd1 of=/mnt/sdcard/appslog.img bs=4096', and then using pull command to get data.
-> Is it a good idea to have a format file like .img? -> How to study (mount/ just read) these *.img files?
..I am using Ubuntu 13.10.
An .img file is less likely to be read as an image file by the Open Source forensic tool Autopsy 3.3.3 (+ Sleuth Kit) [Latest Release at the time being]. However, it can still be opened as a logical file set.Nonetheless, I suggest that you should save it in .dd format instead.
