Re: v 4.x Snap OS backrev to v 3.x on 4000?
Since the OS resides in flashram, NO. The only one I know you can backup is the 2200, 1000v2, 1100. These are non falshram models with the os resideing on the HD. So basicly you are starting over from scratch.
Now I suspect there is some factory software that would allow this. The normal install check the Version and does not allow you to backup. And it does state that the process can not be reversed.
