I tried a lot of things like safe mode, run another camera app, clear cache, wipe data, reinstalled a diferent rom etc, changed kernel from omega's stock to agni (omega's stock was causing me all my apps to FC) but I still could NOT get my camera to boot. I tried runnign the stock test thing *#0*# but only my front camera can boot while the back one FC.
Any ideas what I should do next?
(I have no idea which stock ROM to use and whether I can downgrade from 4.4.2 to 4.1.x or lower)
(I also have no idea whether I can go from R3 of my AGNI kernel to R2 without causing problems)
