Looking for help to root my f460 with Lollipop topic

Yes, I'm using a f460 just upgraged to 5.0.1 by flashing stocked KDZ. Then I find there's no way I can get it rooted. After I searched the forum, the only way of having a rooted Lollipop G3 seems to be flash a pre-rooted 5.0 rom from KK. Unfortunately, there NO pre-rooted 5.0 rom for F460. So I'm wondering is there any way I can get it rooted? Should be doable, when we already have rooted roms.
Thanks for sharing.
