They say it's not easy to be a google engineer, there are many steps etc. Now for me it's confusing to see such a bug from google team;
Press Settings > Reset > Factory Settings, reboots your phone, try to login with your google account, it will ask you to confirm that it's really you by notification bar. And here comes the bug; there is no notification bar! So that you can not confirm anything, as a result your account will be suspended for 24 hours to one week. Congrulations Android team!
The solution; connect by an ip that you have used before. It will be unsuspended then and you may log in to your account.
