4.2 Camera error "Can't connect to camera"

view story

http://forum.xda-developers.com – I'm running TWRP on hboot 1.14 s-off. With any 4.2 ROM that I flash, the camera gives an error reading "can't connect to camera". I've tried factory reset, clearing app data, and installing the camera separately. I'm not sure what I need to do to get it working. I've tried flashing several AOKP, CM, and sense roms, and none fix the problem. (HowTos)
