[Q] Galaxy s4 i9505 no signal on 4.3 or 4.4
i'm using omega rom 4.2.2 right now and i have full signal bars,
but after installing any rom of 4.3 or 4.4 i don't get any signal.
and i get full bars going back to 4.2.2.

1. going to mobile setting and selecting a network.
2. formatting before and after installing the rom.
3. calling the costumer care
4. even flashing 4.3 official firmware.
