give me more details please, what did you do with you reader such that it doesn't boot up?
if you can get into recovery console, than the rescue package can be applied.
but you can also try to format your data partition and reader partition manually from recovery console and see if that helps.
unless you didn't mess up system partition earlier, of course
mkfs.ext4 -L data -m 0 -j /dev/mmcblk2p9
mkdosfs -n READER -F 32 /dev/mmcblk2p4
