Bear with me here...a little complicated for me.

I had a Google Nexus 7 that I sent in to Asus for warranty/repair. They determined that the issue was not covered under warranty and sent my tablet back to me.

When it arrived, however, it was not the tablet that I had sent in. Now, I'm not really complaining, because the one that I had sent in was non-functional and had a cracked screen...

But...the one that they sent also is a unit with which I'm not familiar; it has no Google associations, it has tools/apps I have never seen, and it does not appear that I can update it from Jelly Bean...

I loved my Nexus 7 but I am not a developer or an advanced user, necessarily, just a basic tablet user/google customer.

Am I looking at a some type of developer mode? Is there any way to update to KitKat and resume using Google Play, Gmail, etc.?

Any help is greatly appreciated.

Thanks!
