10) in the upper left side of the screen in Odin there should appear a yellow block that says [com2] (or com 4 or 5 etc. this means that Odin sees your phone.
11) now that everything is ready its time to hit the start button. Odin will show you the progress as you go. after a minute Odin will say RESET, just leave your phone alone until Odin says PASS.
12) OK Odin "passed", now put your SD card and battery back in your phone and do 3button boot into recovery. (hold volume up and down and power all simultaneously until the SAMSUNG splash screen appears then release.
