Hello, I'm Northumber, I have to modify the original firmware of my paladin but I find only .img in the firmware. For example I want to open the file system.img to change the UI and framework but I do not know how to open it. I tried different programs: WinRAR, 7zip and DaemonTools but did not succeed. As I open it?
Android development is done on Linux primarily. Whether it is run on bare metal or inside a virtualizer, it doesn't really matter. You may also be able to go the cygwin route, with yaffs2utils, but that's still "Not windows".
The underlying file system is in the yaffs format, as far as I can see, completely unsupported under Windows.
