[KK/LL] Youtube ads cannot be blocked without Xposed?

Hi folks!

Has anybody on Kitkat Stock Rom (4.4.2) or Lollipop managed to get rid of Youtube adds by using apps like Adaway, Adfree or properly modifying android's Hosts file by yourself?

I've tried all above mentioned possibilities but without any success. It would be great if you can provide any solutions.

Thanks!
