Ok. I figured out the problem. Somehow in my camera settings the “auto off” was selected at 10sec instead of disabled. That accounts for the error message. However, now in the main camera settings, it recognizes my camera and I switch it on, but when I go to the preview screen, the camera icon is greyed out.
Another issue. I reinstalled the old firmware, but there is no way to go from the install screen to the preview screen. Any thoughts? Thank you.
