Xperia Z2 D6502 Lolipop 5.1 root and exploit.

Hi,
I have tried to root my z2 d6502 running lolipop 5.1 without success, my phone is not supported by sony flash tool therefore i cant downgrade, is there anyone working on a new root method maybe we can share ideas, or is there any other way to root my phone?

Thank you team!
