I bought a cool wifi, internet connected picture frame from a thrift store. It had someone else's pictures on it, so I went into the menu and selected "Factory Reset"

After that it never booted past the setup pages with a "unable to get token" message. I messaged the company who was very responsive but the end result was that they said it was unfixable and to return it to the store.

It was only $8, but I was looking forward to a wifi connected picture frame.
