If you still need suggestions, you need to make sure you have the necessary drivers and that when the device is connected that you have USB Debugging enabled and don't have the device mounted (after plugging it into your PC, you get a prompt - mass storage, kies, etc - don't select anything, just hit the back button). The program you tried to use should go through the process smoothly the first time.

 

Make sure you unmount the external SD card. It didn't work for me because mine was still in. Once I took it out( I'm pretty sure you can just unmount it from settings) superoneclick worked instantly.
