How to go back Windows 8.1?

[WPCentral Question]

Good evening,

I am Brazilian and I do not understand much English anyway I will try to explain my question.
I have a Lumia 1020 and installed two days ago Windows Phone 10. I'm not able to use the right device, crashes a lot and some things do not work right.
I want to go back to Windows 8.1, how can I do this?

Wait answers!
