SuperOneClick freezes at "Running psneuter" while rooting. What can I do? I tried to root my new Samsung Galaxy S II today using the instructions in the CF-Root thread and in the videos provided by this guy on YouTube.

I was nearly across the finish line, but when I click the big "Root" button on SuperOneClick, it freezes at "Running psneuter" and won't go any further or shut down (without Task Manager intervention).

I've tried leaving it for > 10 mins, turning off all antivirus and I've tried 2 different SuperOneClick versions (1.9.1 and 1.7) to no avail.

Because of this, I'm pretty sure my root isn't going through properly. Mainly because when I check if my phone is rooted properly I can't get su access in shell.

Any ideas/thoughts about what to do?
According to an answer I got a thread I made at XDA Developers, it looks like the phone actually is rooted because the whole idea with the CF-Root Kernel I used is that it comes pre rooted (which makes me feel slightly sheepish!).
