how to?

[Android Question]

What do you do when it says "missing system/bin/su" on the NT hidden settings app? I've googled it a lot but I can't figure out how to download any apk stuff. I have a nook and I'm trying to get sideloaded apps but when I click on the unknown sources tab in the NT hidden settings app it says missing system/bin/su

It means you're trying to run a rooted app on a non-rooted device. An app calls su when it needs root access.
