Getting super frustrated!

Short version.
I had nothing but problems with my K2 since opening it last December. I spent about 5 months going back on forth with support replacing parts, sometimes the same part multiple times.

I eventually talked them into sending me a replacement. I had to send the old one back and finally got the new one last week.
I was able to get someone to help me unbox this today.(I’m disabled and couldn’t unbox it myself)

I unpack everything and unscrew everything that needs to be unscrewed.
I turn it on and…I’m getting 3 errors right out of the box! The CFS is not even hooked up yet.
One code (2766) isn’t even in their wiki.

I am getting very frustrated at this point…

In case anyone is interested, I’m attaching a screenshot of the errors.
