What is the error ur coming up with, please specify. And be sure that u copied nitdroid's files in /hom. EDIT: sorry i missunderstood ur post, just woke up from ma bed. ur nitdroid will need an mmc to boot, anything in the microsd slot will work even empty damaged worn out mmcs just plug in anything, BUT after nitdroid is boooted up take out ur mmc and check if it's still on
