So I bought this device secondhand from some guy on craigslist. I did a factory reset and first thing i tried was to use gamestream. However, after installing my drivers on my PC, my shield is now saying "Update system software to stream games from myPCname." Upon clicking that, it seems that this is already the latest version.
From my assumption, the previous user rooted and did not unroot causing this to happen. Can someone confirm this or lead me in the right direction?
