I want to root my device but i cannot succeed in this.
The device was bought via an offical Meizu distributor in Europe.



I have Flyme 6.1.3.2G firmware and i followed a couple of guides (SU, ADB, enable bootloader, etc...)

And i do succeed in following these guides, and i can get my phone rooted...but i have no access to the root.
(no super user, Fastboot oem unlock failed, Binary is occupied, used SU 2.79, bootloader is locked...)

I was even so desperate that i used KingoRoot...but that also failed


But then i see that people say that the pro 7 is unrootable, or that  the bootloader is not unlockable...


So please tell me what is possible and not possible with Pro 7 Flyme 6.1.3.2G?
