Default [Q] Chaos/Hell opened up... should I unroot?

I opened up the gates of hell. First installed international MJ9 ROMs. Then erased my internal after backing up EFS to the internal... derp.
Now I don't have IMEI info. it's NULL.
I am growing tired of reading non-Verizon-GNII topics not helping much to solve this issue.

And for some reason my phone is keep spamming "FACTORY MODE ON"

I wonder if I unroot my phone and upgrade it to OTA 4.4.2 it will fix everything.
Any ideas?
What should I do to go back to stock 4.3 or 4.4.2?

P.S: Got out of Factory Mode.
