Help Constant crashes even after reset

[Android Question]

Hey there, I was usking my LG G3 and suddenly I had problms with youtube app, after restarting the phone I kept recieving message that com.android.phone process has stopped working, and basicly i keep getting this message every 2 seconds, i press ok and another pops, I cannot enter settings because they crash as well. I pressed some buttons and went to factory data reset, however after the reset i still keep getting the message about com.android.phone and also i keep getting other messages that other stuff is crashing, this time so often its impossible to navigate the phone. The phone ahsnt been ruted and its been working perfectly for few years. No idea what to do now.

It's a long shot, but try just pulling the battery out for a couple of minutes (I know most LG G-series have removable batteries still). That would ensure that the semiconductor is fully discharged, which would fix some types of error.
