Thanks for looking into this

Basically, I turned the device on the first time, and went through the registration process, of course getting the error. I went back, as far as I could. But the last page I can get to is Step 1 of 1 but on the youtube video, it shows that the four corners step is done before this page. I cannot get back to the first screen to press the four corners. I'm stuck in the registration process. I hope that's understandable. Thanks again!
