[AT&T Samsung Galaxy Note II] royalh:
Tried searching, but didn't find anything related to the 3.0.xx version.

TWRP is unable to mount external SD card.

2.8.xx version can, although it has the runatboot.sh ERROR = 1 problem.

Running boot script...
I:/sbin/runatboot.sh process ended with RC=0
Done.
