Lost root after editing build.prop
I made a backup of my build.prop file before I changed anything. The issue is that after accidentally changing the sdk version to 19 (should be 17) I cannot change it back because I don't have root anymore. When I go to the Super su app it says that there is no su binary installed. So can I refresh super su zip to fix this, or do I need to re flash a rom. I don't have a recent nandroid backup, but I do have older ones if that is the only way to fix it.
