Has it ever worked. That code is for bad/no cable signal
No, it is a new box received less than a week ago. I also made a reddit post with more info.

Copy of info:
New x1 set top box, I can't seem to get past the setup phase due to this screen never progressing. The error code given is "RDK-03005" and after trying solutions shared in other threads or from the forums, I still suffer from the issue. Attempts include: -Resetting set top box via power cord (30 sec wait time). -Disconnecting and reconnecting coax from splitter to set top box (used old splitter and new splitter provided with self-install kit, and Gateway is on other output working fine). -Restarting device from xfinity my account app as well as the system refresh. Other information: I enabled MoCA on my Gateway and have no other set top boxes. I am able to view my channel lineup in xfinity my account app and watch shows on services requiring xfinity authentication.
