OK...here it is: only for people with 5.1.1 G925F (should work with 5.0.2 F also) the G925I seems also fine
be sure to copy my kernel zip and also the super su zip to sdcard (phone) before you flash the recovery via odin, otherwise you got bootloop (because of system write protection-new with 5.1.1)
Kernel (flash with twrp) : https://www.androidfilehost.com/?fid=24052804347765201
Super SU (flash with twrp) : https://www.androidfilehost.com/?fid=24052804347765203
and TWRP 188.8.131.52 (flash with ODIN) : https://www.androidfilehost.com/?fid=24052804347765202
after all that you get the normal system warning (the old one also on 5.0.2) delete Securitylogagent and reboot
