ooops i got it wrong

just got my alien 2 +

and managed to screw up enigma 2 when i go to menus it just gives me a black box

so i rebooted into spark which is not as nice

so my questions are what image should i get where do i get it

and how do i put it on the box?

sorry im new to all this im a bit of a geek so can be geeky with me

i decided to get a linux based box as my humax freetime box went wrong and they would not replace it so i refuse to buy one again ...

thanks ... any image you recommend as im a beginner

is the alien2 triple the same as the alien 2 as far as images are concerned
