Thanks, this method helped me. For anyone else that didn't understand what to do because of the a bit poor English (no offense spitya ;_; ):
1. Root your device normally like you would have on your previous 4.4.4 firmware
2. Power off
your device and enter into download mode
3. flash the the following file from spitya's fourth step with Odin
Or I don't know, maybe people do understand what spitya said. Thought I could make things a bit clearer.
