[G4 General] laperro:
Sorry I didn't get back to this till now, anyhow, here's the output from /system/bin/toolbox mount from a adb shell:

...and from Send_Command I get:

I should be able to make time to get back here a little quicker now, been a little busy.

Since I'm pretty new to Android/mobiles in general (been avoiding them as long as they've existed), kind of hoping doing this, and a ton of reading/tinkering will put me on my way to being able to contribute something besides questions at some point. While, hopefully, not creating a brick that is (though to my way of thinking, "no root" is even more evil and wrong on a tablet than on a pc, so it's kind of a brick already).

Thanks in advance!
