Device offline if I try to push there. I'm running CMD as admin and have ADB set to always run as admin so I don't think it's on the Windows end. Also if I try to push su to /sdcard/ from the command prompt I get a copy failed: Permission denied message. Currently have USB debugging on and connected as mass storage. I can LS all day around the file system, even checked /system/bin/ to look for SU, wasn't there. But I get the device offline if I try to push anything. That mount command gives me an operation not permitted error.
