Six months ago I have purchased the Blackview BV8000 Pro. Until today, it worked well, but due to unknown sogtware error, the phone do not accept graphic key and did not take fingerprints. I did not change anything in the settings and I remember the old graphic key pattern. The number of attempts to enter a password due to an error is not limited, so I can not reset the password. All this has led to the fact that I can not use my phone. Also I do not want to lose important information from this device. Please tell me how to reset the graphic key pattern.
Thank you in advance.
And yes! Technical support does not work!

In this video through a bug I managed to access the smartphone without entering any password, then make a backup or save your data!
