Hi Dominic, we talked last year when I finally rooted my older nexus 7. By the time we talked I had figured out the problem and rooted. (Wish I could remember how!) The trouble I'm having now is rooting the new nexus 7.2 (2013).
Accessing the nexus from the pc is no longer a problem. The link Prime provided works great. The only reason I brought it up was to wonder if maybe that was why Wugfresh toolkit could not find adb to link to my new nexus.
For rooting help, we both need a real expert to help us. I need root because many of my important apps won't work fully without it: firewalls, Titanium b/u, nandroid b/u, Stickmount, Rom toolbox utilities, Tasker, lbe security, etc. So I've got to root.
Thanks for offering.
