newbie here, having difficulties. after encountering problems with the latest bin (255), i decided to go back to the older bin that worked fine for me. i flashed the factory and then the 248, but when i turn on my system, it takes me to the menu and i am stuck there but i cannot access the parental control to get to the key input and all that other stuff. I tried other bins as well, but none fix the problem. I can only go between the main menu and the language selection, and i have no access to any channels. please help. thanks.
