Motherboard changed cant flash any rom?

Hi people my motherboard burned so i went to change it. They changed it. Phone came with KitKat. I cant flash any rom. Even with Odin. Flash is succesfull but phone says Emergency Calls Only. I updated modem to latest lollipop version no luck again. I send my phone to repair service again he fixed it without touching firmware, bootloader and modem.Any chance flash rom?

That happened 2 months ago. But i missed flashing.
