Can't root Xperia z2

[hamdester]

Hi, I've just flashed android 6.0.1 to my Sony z2, and it's really great, it was running on kitkat and I had no troubles to root it,... Now I tried to root it with (kingroot, iroot, root master...) but noone seems to work,.. I don't have a PC in hand,..so could anyone help me with a trick or an app or something
I appreciate any help 😊
