Question [Q] No service unknown network type

Hello.
I have a problem with my note 3 and looked for a answer several weeks with no luck.
My problem is when i put my simcard in the phone i am not getting any signal there is only a circle with i line in it instead of the signal bars, when im trying to find a network its just say cant find any network right now, please try again later.
The phone is from denmark so i dont have the service code to enter the hidden menu to check the radio. My imei number is fine but the phone has been rooted and when i will change the cdma options to USIM from NV it just getting back to NV maybe that is the problem. now i am in stock rom but with no luck either.
Hope someone can help me because i am a little desperate.

PS. The phone is getting really hot and using the battery in a couple of hours when i put flight mode off

Thanks
