    After you gave the step to plug in phone after assuming Odin is open, you go right into now that your device is rooted? You dont even give steps make sure this or that is checked, click PDA select this or that file etc. What sort of incompleteness is this? be thorough, because there may be beginners reading your post and brick their phone. Thanks.
