[l11jur]

There was automatic update today and TV is not working like it should now, youtube is not opening, stupid new menu what I hate, new volume bar it looks stupid and I dont like it. Previous version was much better. Please how to reverse all back, I know there is no official way back but I want to do it anyway. Please help. Im quite good with computers just need instructions what to do.
