I found something that helps, reset TV to factory settings, before that write down your region and backup programs to usb, then after restoring, set region and restore programs, new browser is gone, but every time you run browser it asks for update and you have to press launch. I found it in a thread and also users suggested to watch movies for free in watchsomuch.tv which was a great site and is fully compatible with WebOS browser. If pay you can watch outstanding 4K qualities on LG OLED
