Hello, i have the Problem that the LG ODD did flash my Optical Drive 16NS55 to a 16NS40 automaticly. Now the Drive dont come out when i press the Drivebutton to lay in a UHD Movie. I cannot downgrade the Firmware with alle the tools out there like Asus ODD M. or SDFtool Flasher all versions. What can i do? Recover my Drive did not work and flashing is impossible.
