I had this and what you need to do is unmount the sd card and re-mount it again umount /and mount /dev/mmcblk1p2 /and I think the above commands are correct, but double check on the install instructions it worked fine after that I just cant use this version of Android as I get too many process errors for it to be useable and the previous version that worked great didnt have working wireless So im sort of tuck now until another build comes out
