I had this ROM on my Rezound. It is the best ROM for that device, so I installed it this phone.
I didn't have GPS working though. Google maps, navigation, and GPS status all believed that GPS wasn't installed on my device. I redownloaded and reinstlled this ROM thinking that could be the issue, but I still don't have GPS. I went back to Clean ROM and GPS is working w/out any issue.
I ran the LGFlashTool and put the factory image back on since I was still having GPS issues. Since then, GPS has been working. I'm back to using this ROM, which is a great ROM.
