I am using Raspbian 4.9.35-v7+ (3B+) and the camera: https://www.adafruit.com/product/1567. This may be flagged as a duplicate to previous questions under similar titles; however, none of their answers were able to help.
Unfortunately none of these helped. I have tried update, upgrade, reboot; disable_camera_led in boot config (saves after rebooting but does not take effect); camera.led = False; GPIO executable; and sudo rpi-update firmware looks to give an error of
*** Invalid hash given
So thus far during the preview and capture functions of the PiCamera, the red LED light is still on, and I would like to disable this LED at all times.
