Default [Q] Trouble Rooting

I'm a new user so I can't post in the Development section of the forums where the post I'm refering to is.... so here's the link: http://forum.xda-developers.com/show....php?t=2192467

It's Matt's Utility. I have A RAZR XT912, all the up to date drivers, and I'm still having a problem. AnoraxAudio is having the same issue as me but didn't get a reply (his post is at the bottom of that page, so that could be a reason) http://forum.xda-developers.com/show...192467&page=11

Here's the problem coming up: Click image for larger version

It's giving me operation not permitted and such around steps 4-5. Also saying it can't find some of the directories. Does anyone have any insight?

Or could someone repost this in that development thread for me? The New User limitations are really frustrating...
