I was able to get all the way to the "Press 0000" to enter the "Advanced" option, but it will not allow me to access this menu with that combination.
Is there an alternative way to access PWM for these 2020 Samsung TV Models?
info+menu+mute+power to switch on the tv, and enter inside the service menu
then go to svc->other settings->data restore like in the video
then go back to main menu, go to advanced key and keep "volume up" key pushed for 5 seconds using the new control, like in this video: https://www.youtube.com/watch?v=hGCxvYBJoek
