what happen to urs? my phone can't connect to pc~

My case is I tried to root, but not successful even i followed the steps. Not sure why. I posted my log in previous page, do have a look if u are able to assist me.
For your case, i think is it because you are still enabling your USB Debug mode? Please disable it the first time you want to connect to KIES (pc). Else, uninstall and re-install before rooting.
1.Install KIES to your pc
2.Plug in usb to your pc to connect to KIES - this will allow the Samsung driver to install (PLEASE DO NOT DO IT IN USB DEBUG MODE)
3.Close/Exit KIES (Check Task Manager if you fully close the application)
4.Set your USB Debugging mode at your device (settings>applications>development)
5.Run DoomLord RUNME.bat (follow as per instruction on first page).
Good luck in your rooting.
Mine still no news of success. Still waiting for a forumer here to help
