The documentation isn't helpful. I have a constant blue light and never turns green. Brand new C-7. Yes, I know it's the prior model. But, it's brand new.....brother had it and never opened it.
Your links don't even work. Why would they move them????

Please feel free to start a new thread with as much information about your Hub Set Up problems as possible.
Lots of screenshots can be especially useful to help diagnose issues.

Really old "firmware" on the hub can be problematic. 
Here's a thread with the procedure to manually update your Hubitat Diagnostic Tool .
I’ve gone ahead and done that for @kbaum17.
Nothing will work if your hub's led doesn't turn green. Unfortunately, you are likely dealing with a hardware malfunction, which requires a replacement hub.
If you haven’t already done so, please submit a warranty claim here:
Since the C-7 has not been sold for quite some time, the original purchase date would normally place it outside the standard warranty period. However, if your brother previously contacted us about this issue and submitted a warranty claim while the hub was still covered, we can use that original submission date when determining warranty eligibility.
If this is the first time anyone has contacted us about the issue, the hub would no longer qualify for a standard warranty replacement. Once you submit the claim, we can review the hub’s history and let you know what replacement or upgrade options may be available.
