Just borrowed a friend's O3DS on 10.9 SYSNAND with A9LH & OLD Luma. It's working fine & not banned as far as I know from what my friend told me. Edit: on Luma 6.6. The official update (not sure what version) was downloaded via Spotpass so I am trying to get into Recovery mode to delete it (holding L+R+A+Up when power on). Any idea?
