This tool will root you nexus 7 install su or super su and ClockWorkMod recovery!
i already developed a similar tool for the nexus s and galaxy nexus,this tool is based on the same code with few modifications.it should root your device in few minutes,so give it a spin and tell me how it goes
just unzip the content and run the tool ! drivers are included in case you need them (not sure if the drivers are working though)
ALL DATA WILL BE WIPED
FROM DEVICE(only if bootloader is locked)
