[Q] Nook color with no emmc and I don't know whats been done to it topic

So I bought this nook for my partner and now it won't boot. I like to think I'm comfortable with all android and every aspect of it but I'm likely not. the nookcolor-emmc-repair-partitions threads (both) don't work. So apparently he's erased partition 3. Thats about everything I know. Can anyone direct me anywhere or give me the most basic detailed instructions on how to do adb?
