This is the korean kk release just slightly modified by me to install without the need to freegee after installation so you should maintain your current recovery.
I trimmed it down by removing the Olleh branding apps and boot/shutdown animations. Forgot, I deleted the LG Music app because it stinks. Doesnt do gapless mp3's which I have a lot of.
I replaced with AOSP music app with gpu acceleration enabled so it scrolls smoothly and plays gapless mp3's.
No modem is flashed either, just make sure you are running the jb modem.
Only other thing I removed was the root checker daemon because it was spamming logcat (rctd: similar to this: http://forum.xda-developers.com/show....php?t=2267909)
Don't expect a lot of support for this, its not my work, I'm just sharing it to try and stop all the problems that are occurring from the original zip released by Hoangnova whom all credits should go to.
All you need to do is flash this zip and the latest UPDATE supersu zip, don't forget to wipe clean.
