removing gen 1 from s2

Hi, I normally flip my eras in and out of surround sound mode for my beam.. however it won’t let me tonight as it it’s asking for an update to the system. Looks like it’s an old gen 1 connect causing issues.  I thought it was dormant as I’m only working on s2 and didn’t expect that to be visible (which it isn’t in the homepage) I’ve tried doing a factory reset on it and downgrading it to s1, but this fails. Any ideas how to lose it completely from the state so s2 operates normally?
