My husband has a Huawei P9 Plus and after the battery was completely empty and it was recharged, the phone does not recognize the individual unlock pattern anymore. About the google account did not work. What else can you do?

Enter password.

The possibility does not exist somehow. First was after 1 minute, then after 5, 10, 30 etc and now after 60 minutes try again, no pattern forgotten or forgot password…
