Great XDA devs work on this exploit for a days and, believe me - it's not fake.
It relays on Android/Google security flaw, not Sony so it should work on many different devices.
Read and search a bit if it's not working for you, there are solutions.
One if the solution is to install latest supersu 2.0 (that's important, because supersu is updated yesterday on market - and if you use that it's normal you failed) before you even start to root device.
Hit update binaries, you'll get error but that's normal.
Then download v4 root tool and start it.
After that, restart and try to update supersu binaries.
It's possible that you'll need three or four times to succeed but it'll work.
It's working on Z2 KitKat and it'll work on Z1/Z1s/Z1c KK.

Many usersdon’t see any particular reason to change out the stock firmware … more
