I installed the all in one rom from liberty to start off and had the normal issues of having to install google apps, gps fix, and the camera fix. I was able to use the camera using the button on the screen. I then installed the latest nightly 21. I wanted the MIUI camera so I installed it using the 3 steps here http://forum.xda-developers.com/showthread.php?p=15219508#post15219508. Post 167. I went into the camera and all it showed was a black screen. So I ran the camera fix again and it now still shows just a black screen. How can I get it to work or go back to the original camera?
