Console OS/Firmware Updating

I hope there is an actual way to do this already, but it would be outstanding if there was a way to update the Console OS via a built in prompt on the Onyx Console OS rather than having to create a USB drive with the OS installed and go through that whole frustrating process. I’ve been working for a week now on updating our console OS and have not had success doing so. We’re trying to update from 4.6 to 4.8 presently.

If there is a quicker way to do this, I’d love to know about it!

Sometimes it is a full windows installation, that can’t be done just like that. That’s why it needs to be on the USB. But if You are only updating a version like X.X.xxxx > X.X.xxxY This can be done just via the menu in the console.
