Stuck at Odin mode

I wanted to see the Recovery mode and Download mode. Here in Download mode, I didn't do anything.. I wanted to turn it off and boot it normally.

It's stuck there.. Downloading... Do not turn off target

I can't turn it off. Obviously I can't remove the battery. I'm guessing my only choice would be to wait for the battery to run out.

Any idea why this happens? What else can I do? What if once the battery runs out and I try to turn it on, it returns to this state?
