OK, I am getting some issues.
I am in debugging mode and Mass storage setting.
I follow steps 2 and 3 in the OP as stated and get no errors while issuing them thru ADB.
I reboot, but none of the settings stick. So I check my sdcard (while unplugged) and the install and setscale docs are not in there.
I plug back in to the computer (debu/mass storage) and I look on astro and boom! the install and setscale docs are on the sdcard now, but disappear when I disconnect from computer.
I am doing something wrong, obviously, but I don't know how to make it stick to the sdcard after I unplug from computer....
