How do you write NVM on i9507?

I have the NVM file but there is no option to write NVM on Z3X box. I would use Samsung Tool 17.9 but that is impossible to get.

Actually NVM got it to write, found 16.7. Should fix 3g / 4g after writing NVM?

Selected model: I9507
Selected port: COM9 USB Serial Port
Selected port speed: 115200
Reading phone info...
Reading IMEI... OK
IMEI: 0
Writing NVM... OK
Done with Samsung Tool v.16.7
