First Sorry for my Englisch 
I have the I8190 originally 3AT but now unlocked. My problem is if i flash any Samsung based or stock 4.1.2 firmware all works fine, i have service, wifi and 3g but if i flash any custom rom higher than 4.1.2 like CM 10, 11 or 12, Omni or Miui i have no service but wifi works correct.
I make a efs and modem backup from stock rom and restored it on every custom rom but it doesent work.
Did anyone have an idea?
Thanks
