ok, i'm rooted now and on miui rom. how do i create backup image? I have a .bin file that looks like revolution created. Thanks very much for your helping a n00b. I should probably clarify what im trying to do. I've got miui installed and working, i'm looking to make a backup image of my factory phone (pre-rooted phone) so that I can (hopefully) dual-boot the two or at least have a complete backup of what I had before I started the root process.
