My nokia lumia 520 have a problem to turn off the flight mode after the update

I have tried to do so many things, to wake up the phone using the up volume key and the on button, to re-update it but after the update the nokia lumia 520 windows 8 doesn't turn off it twigeles between the on and off. What should I do?

Try removing "airplane mode" from your Quick Actions under Settings/Notifications+Actions. Let us know if that resolves the problem.
