  • I applied method 2, after installation there is a warning “ONEPLUS A6000 setup in progress, tap to finish ONEPLUS A6000 setup” then when I tap the start button it starts checking for updates and does not stop it. So there is no update or progress, and accordingly google play store, some google apps do not work. I could not add an email account and gmail does not work either.
