Unhappy [Q] Help please s4 active unlock gone wrong

I accidentally hit the option 1 debug screen in the service mode on the (s4)active sgh-i537 and it cleared the entire menu and now it won't read any sim and there is no mobile network to be found and all I get is a circle with a line in it . I can get back in to service mode but there's nothing there at all . I tried to reinstall the original firmware but nothing. It all started trying to unlock it . Any help would be greatly appreciated thanks in advance
