[Xperia Z1 General] Seelbreaker:
Root isn't working?

So i downloaded this - wiped with Team Win Recovery, installed this zip rebootet....

- Rom works

- Dual Recovery works

- Root isn't working - tested with Total commander - i gave it root Permission after the app asked for it, but i can't remount /system in rw.

Remount Reboot fix from nut isn't working also:

any ideas? I mean srsly, bootloader is unlocked and i can't use root to edit the freakin host-file -.- For everything else Root is somehow working :(
