From what I understood, you seem to have issues rooting your device? If that is the case, here's a tutorial that might help:
1- If you are using stock Gingerbread 2.3.x, download "siyah-2.6.14-CWM.zip", extract the .tar file and flash the file using ODIN 1.85.
2- If you're using stock Ice Cream Sandwich, download siyah-5.0.1.tar and flash it through odin
3- If you're on stock Jelly Bean, download siyah 6.05b.tar and flash through ODIN, or download dorimanx v8.43.tar and flash it through ODIN
Simply, check your Android version in Settings>About Phone and root your device easily with any of the above methods. if you don't know how to use ODIN or boot into Download Mode, simply google these terms and you should get more answers and detailed threads. Good luck
