Extract files from Android system image? Is it possible to extract files directly from an Android system.img file or do I need to load the system.img to a device first and then adb pull the file from the device?
There are tools to extract that; however, not all files named system.img have the same format, so there's no guarantee that it could be done. Nevertheless, check out the tool I've been personally using: LINK. This is meant to extract system.new.dat files introduced in Android 5.x, but also includes system.img capability.
