Hello, I did everything I was supposed to, set up everything, even got an email saying bit was good to go. I can still only get to the part on the screen, that says enter your email for setup, which I already have done. I can't do anything else! It won't even let me go to already have an account, to sign in!
Try unplugging the power for several seconds and plugging it back in. It should either start up and be linked to your account or start over from "Select a language".
When the setup fails to complete after the software update runs, here are a couple of things that some people have found to work for them. They may not be universally successful, but they are worth a try.
Easiest to try, so try this first: Restart your router, even if other devices have no trouble connecting. When your router has completed its startup, try repeating your Roku setup.
More involved: Repeat the setup by connecting to a different wifi network - perhaps via a wifi hotspot on your mobile phone or by taking it to a friend's house - and see if it will complete the startup. If successful, then redo the wifi connection to use your intended wifi network via Settings > Network > Set up connection.
