Sorry to hear that
So for the Gear Fit, Sammy uses a different manager? I use the same manager for the Gear 1&S, and the updated gear manager still connects fine with my Gear 1, it just wants to wipe my Gear S.
I have a feeling it is trying to push a firmware update on the S, because when I do a fresh install of Gear Manager, then try to connect my Gear S, it says it needs to download additional software (Gear S firware update, I fear), THEN it tells me it wants to wipe my Gear S without leaving me any option to refuse the update. It I select cancel, it just closes out the Gear Mgr app.
My Gear S works fine stand-alone (I do wish I could install the Instagram app, for which I'd need to connect to my Note 2) since I track my runs in Nike+ now. To me, the fast GPS lock and stand-alone phone capability is more important than interoperability with my Note. I wish I did not have to choose, but that's Samsung for you: always screwing up something. If they didn't make such great and visionary hardware, I would have left them long ago.
Also, glad you told me about the Fit and Manager problem, because I am constantly drooling over the Fit form factor, regardless of the fact that I have no need for it. It would be cool if they came out with a Fit 2 with the same form factor but better UX. Unlikely, huh?
