I'm using Asus Zenfone 2 laser Android device. For a specific reason I did factory reset. After reset I tried to access my mobile. It asked me to use Google account which I used before in that device for sync. I did that too. But again and again i'm seeing "Please sign in using one of the owner's account for this device". I tried so many times using all my previous Gmail ids which ever used in my mobile. How to resolve this issue? I checked in Google and got results for some Bypass Technic which I don't want. I need the root cause and the proper solution.
Note: Before resetting my mobile I changed the password of my Gmail id and I used the updated password. I'm not sure whether it would be the reason. If so how to fix this?
