Re: Galaxy S 6 edge camera warning camera failed
Is the battery above critical level? If your battery is at a low percentage the camera app won't open.
As long as you flashed the ROM correctly and you like it and don't notice any problems (battery life, performance, etc) then you'll be fine. Also, it will take your phone a few days to get used to the new ROM.

Make sure you have USB debugging enabled under developer options and you are using a reliable sync micro USB cable.
