Odin mode on tab s?

[Closingracer]

I was trying to clear system cache and I figured it was the typical hold power button up on volume rocker and home button like on the note 3. I got asked about something with installing a custom os and said push volume rocker down for restart and up for something. Me forgetting which is up and down on this thing pushed up when I meant to push down and now have this screen

I can return and exchange it at best buy or can I fix it?

Any way to fix this ?
