I've rooted my Captivate once before using Odin before. Now I can't get my SR to be rooted. I'm using SuperOneClick and followed instructions and it just doesn't seem to work. My computer says program not responding. This is how far I get.
How long did you give it to root? There are several pauses where nothing seems to happen. The script on the right side looks correct, but there are quite a few steps after those.
