Welcome to our AndroidForums,
@SoniMax .
I'm guessing that you could best get help from the SG S5 root area (
http://androidforums.com/forums/root-samsung-galaxy-s5.2583/)--I'm not Samsung guy, but there's lots of great and very knowledgeable folks over there who I'm sure could help you.
Lemme know if you'd like me to move your thread over to there.
Cheers!
