If the mini is patched and you can't see the path to the biss or other encrytions,when you press the menu button,then you need to press f1/000 in view mode to enable the patch...I think
Okay got this working well with 28.2e/27.5w, BISS can be changed with the remote in menu mode.
Only thing is that the channel file is sdx format, can someone point me in the direction of a channel editor, tried Google and other forums but keep drawing a blank.
