Hello, I got a refurb Nexus 7 2012 model for Christmas -- and it wants to install an OS update (4.2.2 it says). When I start the process I see a progress bar, then a graphic of a little droid with a spinning ball -- then after a little while I see the little droid on his back, with a red rectangle containing a "!". Then it restarts.

There are no text messages to tell me what's happened, but I take it the update failed, since the Nexus comes up almost immediately announcing again that system update.

Is there an error log hidden in there somewhere? Any idea what I might need to do to fix this?    Thanks              -- Howard Ballinger
