Page 1 of Shinco 8320 newer model hack

I have this model and the stop, setup, pause 1,2,3 method does not work; I suppose this is one of the newer models with the hack removed as I have read about. I fond another site wwhich says that open 7, enter, 7 will work, but this unit`s remote does not have "enter"

Does anyone have any ideas, or can point me to a site where I can download different firmware. Has anyone downloaded different (or older)firmware with any success.

thanks
