My K750: prgCXC 125955_HONG_KONG_CL R1A044
Camera version: 3.8

I have downloaded the driver camara_driver_v.6.0.rar. After I flash the drvier. I half press the shutter, the camera can focus. And full press the shutter, the camera look like has taked the photo. But after it processed, it exit the camera and don't save the photo. I rollback to the driver 3.8, it work.

Do I need to upgrade the firmware before?
