How to root Galaxy S5 on 5.0 lollipop now TWRP and CF-Auto-Root don't work??

What's the best way now to root SM-G900F on lollipop? Knox is already 0x1 so that doesn't matter.
TWRP doesn't flash anymore (others are having the same issue and it doesn't even trip Knox as it doesn't work) and trying CF-Auto-Root got me into a bootloop again. That bloody tool never works for any phone I try it on..

What are the other methods that still work?
G900FXXU1BOE3 this one is.
