Root and Cyanogenmod

Hi all! I recently got a Huawei P9 vodafone branded (L09C02B123) and I am very happy with it. I wanted to ask if there is a safe unlock bootloader and root guide for this version or do I have to de-brand it? And if I wanted to unroot the device can I go back to the vodafone version as it first was? And since I don't like the MIUI software (the only downside) when will the CM 13 roll out to the device?

Thanks
