How long does the “update” take on new equipment

@Rickoshell 

Uverse TV has no new equipment, so please elaborate more about what you have there.  

We'd be happy to help you with your device's update, Rickoshell!

Please give us more information about what you're updating so we can make sure we give you useful and accurate information.

We'll be awaiting your response!
