How do you get iPod touch out of recovery mode?

I've already tried the methods listed here and on Youtube, and this has happened before. I have a new iPod Touch 5 16GB and the latest iTunes. The first one I bought went into recovery mode right after updating it to the newest software at the time. I contacted apple support and they couldn't figure it out, so I had to return the iPod to Best Buy and order a new one. I was just trying to update to ios 8.2, and now it's stuck in recovery mode. It says there's an error where it can't be updated and needs to be restored to factory settings, but when I try to restore it, "The ipod "ipod" could not be restored. An unknown error occurred (3194)".
