3.0 ROMS
Now that you have ROOT and a CUSTOM recovery, you might want to install a new ROM. And there are truly a lot of ROMs to choose from, so which should you pick? While there is no definite guide to what's best, this will give a brief explanation of what you can expect from the various ROMS.
An important thing to note, is that your battery life won't magically improve 50% by flashing a custom rom. While it might improve you should compare it to what you have now, and not the results other people may get.
3.1 Stock Based ROMs
These ROMS are based on the stock User Interface (UI) that came with your phone. Many of these ROMs do not have useless apps pre-installed and might have a feature or two added to them, like the split window.
These ROMs usually have very good stability, are fast and have good battery life. Search around in the G2 Android Development section and follow the instructions.
3.2 Flex Based ROMs
Flex based ROMs are quite similar to stock based ROMs - except the User Interface is black. They are stable, fast and have good battery life. All of the flex based ROMs include split window and the ability to hide the navigation bar in certain apps.
3.3 G2 PRO based ROMs
These ROMS are less common and very similar to the G2 stock roms in terms of looks, stability and performance. The most unique feature of these kind of roms is that it allows you to get a "mini-view" by sliding over the navigation bar. These ROMs also include split window and the ability to hide the navigation bar in certain apps.
3.4 G3 Based ROMs
These ROMs are often the most-sought-for ROMs as they have a nice, modern Flat UI and tinted status bar that changes in accordance with the color of the action bar of the application. Many find it the most visually pleasing ROM, but it's also a bit more demanding in terms of hardware resources. They commonly have good stability, good performance and battery life on par with stock, maybe a little less.
4.0 AOSP ROMs
AOSP ROMs are for the Feinschmeckers of Android and do like the AOSP look. AOSP ROMs are commonly less rich in features, but offer an unmatched smoothness and speed. Unfortunately, since the LG Camera sources are closed source, the Camera performance on AOSP is subpar to the that on stock LG ROMS.
Please note that STOCK Kernels only WORK with G2 and G3 based ROMS and do NOT work with AOSP roms
AOSP kernels DO NOT WORK WITH STOCK LG ROMS
