a friend came over showed me how to softmod with splintercell and AR, we did my box so i copy his 2 save files to my pc from his mem card (sam and linux profiles) copy them to my card copy to my friends xbox HD start game, go to load check points, go to linux, BAM xbox goes to needs service screen with a 21 in the top left corner, light flashes red. shut it off turn it on and it seems fine. all 3 xboxs have the same dashboard version (5690?) all 3 are PROBLY differnt versions though, mine (the only one that softmoded) has the vented dvd tray. the other 2 dont. not sure if that has somthign to do with this. both his xboxs do this error. anyone have an idea?
