[Safe Root] Any solutions for fw UBML4 ?? topic

Hi,

We are a lot to search for a solution to root our S4 mini with the firmware XXUBML4.
As far as I know, there are actually 2 solutions to root this phone without triggering Knox (but..) :

- Safe Root by @k1mu but does not work for that firmware...
- Kingo but we don't know if the company who owns it, steals or not information so use with caution...

Any other solution ??
