I updated my Note 4 about two hours ago. When my phone rebooted I was asked to enter my lock screen pattern, which would be fine...if I ever had one. I failed the "test" and was prompted to enter my backup pin, which I also do not have. I was never able to set a backup pin. I bought my phone brand new and it always seemed as if there was a secret pin that it came with, to which I was never privy. Any time I tried to enter it within my security settings it would tell me it "didn't match".
I've rebooted my phone three times.
I have spoken to Verizon customer support. They were very nice, but couldn't help me.
I have spoken to Samsung. They tried their "golden ticket", having me remove my battery, replace it without turing the phone back on, hit the volume down/home/power buttons simultaneously, and select the "reset cache" five times. It still asked me for my backup pin.
I am now waiting for a Verizon customer care rep to send me a proof of purchase for my phone so that I can email it to Samsung. Of course they would like to make sure I didn't steal my phone before they try, again, to remove the security lock.
Anybody here have any ideas?
