I sadly had to put one of the household's Nexus 7 to rest. Symptoms not entirely like yours, except for the eternal boot times. Mine ended up being so laggy it was impossible to use. Good luck!
Thanks. I got a link for a root kit, via the Nexus help forum, as a "hail mary", but I'm not holding out hope. Do you have any replacement recommendations?
