i have a 2013 N7 and am trying to sideload Kit Kat. i have adb and fastboot folders on my desktop. but when i type "adb sideload kitkat.zip" it says "unable to read kitkat.zip". help please?:-$
The way that I sideloaded kit kat was by using the Nexus root toolkit. The method on AC didn't work for me. It takes a little bit longer using NRT because you have to follow a bunch of steps but at least it definitely works.
