Should Scanning for Channels take really long?

Im on a Shield, and trying to scan Fios. It is taking forever? Close to over an hour now. Is this normal?

Update your DVR (click-and-hold the update button), then reboot the SHIELD.

that worked. thanks.

whats the secret when it hangs on a channel?

It's doing the same thing again, and this time the trick of updating and rebooting isn't working. Any more tricks up your sleeve?

Never mind
