Now that the memory is internal, I don’t know if I’m not understanding TWRP interface correctly or what. I press Mount, and Data and Cache are checked with an X; System is not. I don’t see any extra buttons, so I assume those are the partitions it would mount, but not on OS X nor Archlinux does it seem to mount anything.
Am I doing something wrong? Should I try CWM?
Thanks in advance!
