Flashed Lollipop on G900H - no network topic

Guys, I could use some help. I flashed the new Kazakhstan Lollipop ROM on my G900H, but now won't connect to cell network. The IMEI is now a generic number so it must have been wiped.

How do you reload it? I tried to reload the 4.4.3 firmware but it failed in Odin. So went back Lollipop

What should I do?

Thanks, Michael
