For those who might have similar issues. I had to "Restore Upgrade Errors" on LG PC Suite, which failed, and I had to repeat it. DOn't just hit "retry", close program and click "Restore upgrade errors" again otherwise it will keep failing. This effectively returned me to an unrooted v10i. From there I was able to use Software Update on the phone to get the (j) OTA. It is currently Dalvikizing my formerly Art apps and looks like it will work. From there I have to root again and debloat.
