Following your guide to root I had a difficult time trying to make CWM permanent (step 5 of your guide).
During the process of flashing CWM a window pop up requesting a driver. I ignored the request (2 times) and I could not go to step 5.
At my 3rd try I followed the request of installing the driver. Out of curiosity and being cautious I checked Device Manager: Nexus7 shown a yellow !.
I installed the driver and could complete step 5 making CWM permanent.
Taking into account that at the beginning of the process (step 4 for me) N7 had its driver and the ADB interface driver (adb device acknowledged N7 and fastboot flashed CWM) what is the specific reason for asking a driver in the middle of the process?
I would like to thank you for your guide, your time to develop it, and to follow and answer the reactions of the Forum members.
