I just got mine about a week ago and rooted fine with SOC, the only thing is I had to download the drivers first, so my first question is have you installed the proper drivers for your device?
Also I had to make sure it was in zergRush mode under exploit when I rooted it, auto and psnueter both failed. it took it about 10 minutes, and would kinda hang for a while not responding here and there, but I just was patient and it eventually stopped.
I used SOC v 22.214.171.124.
Side note: when I said I had to download the drivers first, I had tried a couple I found linked through these forums that didn't work, in the end I think I had to use the ones I actually found on samsung's website. I'd provide links but I'm a new member and it won't let me :P
Hopefully this helps some.
