Hello, let me first start by saying i am not a complete novice. i have 9 Sonos Devices and have bought broken units and self repaired 3 of them. 

that being said, i can NOT GET THIS STUPID THING TO UPDATE upon setup.

i bought a used Connect:Amp from Marketplace. i tested before i left their house and it was working fine, but i forgot and didnt transfer ownership before leaving. i can successfully perform a factory reset and get to the blinking green LED and i can even add it to my system. however, on the system settings page of the app, i get a message that says ‘Connect:Amp is not registered’ and when i click it, i get the option to ‘fix it’. the setup screen pops up again and and prompts to get an update before continuing and that is when i cant continue. i get Error 1,002. 

i cannot get this thing to complete (or even start) and update. not on wifi, not over ethernet, i have moved it to different locations including right next to the router… I even tried to use the S1 app but since this was already on the S2 app and downgrading is unavailable right now, i cant even do that!!

what is a guy supposed to do!? luckily i only paid $140 but thats still a lot of money for something i cant use! any tips?
