As a follow up to this question, is it possible to use Odin (or Heimdall) to save a complete image of my phone without root?
Odin already allows me to completely overwrite pretty much everything on my phone without root. Can Odin be used to read the entire contents of the phone over USB without root? Ideally, I'd expect the output of such a read to be something I can write in the future with Odin.
While this question is somewhat general, I'm guessing that by asking about Odin and Heimdall I'm limiting it to Samsung phones (though I may be wrong).
