I am having a similar problem, and support also sent me here :(
I got a new phone (nexus 5). I attempt to use the unlocker app. and my original verification code doesn't work. I reset the password today, and it still doesn't work. When I attempt to log into my account it says that my account already exists. No idea what to do.
The ring reads using 'read' in the control app.
Very frustrated that I can't find where to get official help :(
