Hi. Recently i bought used unlocked note 5 (SM-N920V) Everything works fine except system update, I can't get Marshmallow.
I have no verizon contract, live far outside from US and not able to get verizon sim card. I have read that absence of verizon sim card can be the reason.
If I am trying to get system update on the phone (Settings->System update) I got the message “Service unavailable. Software update is temporarily unavailable. Try again later” I'm keep trying whole last week and the message doesn't change.
I also have tried Software Upgrade Assistant and it keep telling me “your software is up to date”.
Could you please tell me the way to get Marshmallow?
Also even if i'm a Verizon customer in some ways i can't see the way to contact the support service. I can't find support email and can not sign up without US phone number anywhere except community forums.
