flashed K550i camera problem

hello all.
A few days ago, i've flashed my k550im to a w610i, without any problem. But after this I wanted to change the camdriver to get better photo quality. So I did it with FAR and JD flasher, but every time I try to go in the camera menu in the phone, it says something like "Another application running. Close it, then start the camera".

return to original camdriver or with other camdriver

try to install new cam driver
