Secret Code Not Working

Hi All,
I have an LG G4 through T-Mobile. 277634#*# gets me to a hidden menu, but not the device testing one. The “For T-Mobile – 3845#*851#” code didn’t work, and neither did replacing 851 with my phone’s model number, 811. Is there no service menu in my phone, or is there some trick not listed here to access it? Thanks in advance.

"IMEI : null" in my LG G3 D855

I am using LG G3 D855 unlocked with Android 5.0 v21a-AME-XX (unrooted) in India. It had battery issue and was doing reboot loop frequently. So I tried to reset the firmware via LG mobile support --> Options --> Upgrade recovery and second time via LG PC suite --> Restore upgrade errors. After that the IMEI number of my handset has become null. I don't know how to restore back. Please help me as I have tried hard reset and factory reset. No use.
I am also unable to view the 'Software info' under settings as it hangs there by saying 'settings not responding'. USB OTG is also not working (tried with different pen drives).
Kindly help me.
If I take it to LG authorized service centre ( http://www.lgmobiles.com )

Try this to restore your imei

No use
I am unable to access software info because something has happened to the firmware. The settings is getting hung and the phone restarts when I try to enter software info.

Can I take backup of the IMEI without rooting?. Your response didn't work as I am unable to access software info. Is there any other way?.
