Hi, @joelm655
Welcome!
I understand that you've attempted to update your Roku TV using a USB file, and I'm here to help.
If your Roku TV system is not connected to the internet, software updates must be done manually by first downloading a file to your computer, copying it to a USB flash drive, and then connecting that flash drive to your TV.
For the complete steps, visit this support article on How to use USB to update your unconnected Roku TV system
Hope this helps.
Thanks,
