the best thing u can do is update pandora card gend-3 final

put it on root of memory card that grader 8 is on
it will overwrite what it needs to
goto card now and run gend 3
when it loads u will see optoin to make xgen pandora
choose that then pop out battery and when u use pandora as normal
it will let u go to gend instead of m33
