Greetings all, long time lurker, first time poster.

 

After excitedly receiving an OTA Kitkat upgrade this morning on my device I have been experiencing an extremely annoying fault since, and have narrowed down the probably causality, but as to the fix I am stumped.

 

Upon booting, the phone will attempt to power up the SIM radio (either slot) and I am presented with an error message "Unfortunately, the process com.android.phone has stopped" - which upon pressing OK will loop around as the phone continues to fire up the radio.

If the phone is in flight mode, or has SIM's removed, then the error will not occur, and works just fine on WiFi.

Attempts to fix thus far: The obvious factory reset, Reloading the ROM via LG Mobile Support Tool...

Variables checked: Tried other SIM's from my normal two, and issue still occurs. and SD card removed to no avail.

OS details  - 

Error as it presents - 

Thanks in advance for any ideas :)

Cheers
