Do you have any recovery installed? If yes, then try go to recovery and wipe everything, do factory reset (you will lose your apps, contacts and other things in phone that you have installed, default will stay. Memory card will be untouched ) (I assume you have, because you had installed custom ROM )

LU6200 3G Lost
Hi.
I have same problem like that.
I have a phone LG LU6200. There was stock firmware 2.3.6 and then I flashed 167.kdz Got root and deleted some stock programs.
After restarting phone showed error "LG Security Error" and then I made a downgrade.
And saw that I lost IMEI numbers. After this I restored imei using this solution. But now on my phone another imei.
Then I flashed custom recovery. When I check only WCDMA option signal is lost. I tryed to flash stock firmware 167.kdz same problem. 3G is not working.
How can I solve this problem?

I had the same problem!
After the upgrade will not work any mobile carrier's CHIP
If your phone is original go to Settings and then find the Factory reset configuration, after this your phone will start working again but will lose your data!

Did you input your carriers correct apn ?
If so maybe it doesn't support the band of your carriers 3G/4G
