Did you ever get a working answer to this? I'm having the same problem. My camera won't open, it force closes before going anywhere beyond a black screen. The night before, it would at least open. The front facing camera worked but the rear facing camera seemed stuck on solarize (which I had no options to change). Seems like a software problem so I updated to the latest deck rom, updated hboot, pri, nv, wimax - now fully updated and still no fix. Tried installing miui apk and still same.
If I don't get this camera fixed, I'll have to unroot. Not looking forward to doing that but if it's between having root or camera, I'm going to pick the camera.
Hope someone can help before I have to go to such drastic measures.
