Yep, I was still fairly a noob at this when I first posted but have learned a lot ever since. Here's what you want to do:
(btw, I factory resetted to 1.4.0--you may need to as well):
When it says "no device found", it's corresponding to this command line : adb install whatevernameofapp.apk . I interpreted "no device found" to mean that it does not know what "adb" means in the command.
For it to recognize all "adb" related commands, you have to have the USB drivers installed. Look for tgps_launcher.apk on this link:
http://forum.xda-developers.com/show....php?t=1354487. That will set you up with having you Nook to accept third party applications + having it on UBS debug mode.
Then, install the drivers (I saw this YouTube walkthrough because it is NOT intuitive and you want to be sure you're doing it right , it's not the way you would traditionally update drivers for a mouse or keyboard; here:

After that, I followed the instructions on
this article, made a folder in C:, called it sideload, and also pasted an .apk. Now, when I do the Commant Prompt, it says this:

Does anyone know where I can find this (data/local wasn't found when I connected the tablet to my PC either, and it wasn't on my SD or so). Is it because I'm still on 1.4.0?
Let me know if you get it working all the way!
