This tool good for 4.1.1?
Yes, under model type choose JRO03C. It will still work even if you have D.

Takes away the stress after mis-typing the same command 3 times in a row etc 
Hmmm can i root it first, backup everything with TB, then unlock?
You can root without unlocking. There's a guide in the galaxy nexus all things root section. Should apply I would think.....

Should I just use the 'C' option and hope for the best or will this effect the unlocking and rooting process?
So, installing the drivers installed pda.net on my computer and N7. Can I uninstall pda.net without affecting the drivers it installed? Can I still use the root toolkit program if I uninstall pda.net?

i rooted my HTC Evo back in the day and i remember the basic steps to doing it. however, this time around, when i uninstall the dinky stock Windows 7 driver for the N7, it will uninstall and then go ahead and re-install the same driver, so i can't force the alternate driver installation before Windows decides to re-install.
can't configure adb, so i'm stuck. any ideas?
