I generated Chainfire`s CF-Auto-Root, so you can try use it.
1. Download and unpack CFAR-taimen-default.zip.
2. Reboot your device into bootloader mode.
3. Install standart fastboot drivers.
4. Run "root.bat" file.
This batch file unlock your bootloader (if it`s not) and boot modified kernel.
Wait, when device automaticaly reboot. Then just install SuperSU apk.

I do not give any guarantees of it. If it causes bootloop - flash factory image.
Tell me if it works.
