Default [Q] How to downgrade from 4.2.2.?

Hi,

I'd like to ask for your help. After an update to Android 4.2.2 and Sense 5.0 on my HTC ONE SV I'd really like to go back to the previous version, I know a lot of people are happy about the update, but I'd really like to go back to the older menus, look etc. I don't mind losing the data.

I'm new over here ... so please bare with me
What info should I provide?

Nina
