No service issue

All of a sudden my OPO started to show No service. But it detects the sim and imei shows a valid value. Wifi works properly but the neither calls nor data. Once rebooted the device shows Airplane mode when power button is long pressed but it is not shown in the home screen. It was running the latest OTA. I tried
* deleting APN and loading the defaults
* trying to turn on the radio via *#*#4636#*#*
* flashing the latest OTA via recovery
* flashing the latest factory image via fastboot
* flashing an old factory image via fastboot
* flashing an old modem via fastboot
none of those methods worked.
Please help me to bring my OPO to normal condition. Thank you.
