Default Installed CM11 on HD+ Want Stock 2.2.0 Back

Hi guys, I hope you can help me. I installed CM11 to my Nook HD+ following the thread [EMMC CM11 install - updated 01/18] I am having some problems and wanted to go back to stock Nook 2.2.0. The problem is I don't know how, I am more lost than when I first started. If this has been asked before I apologize, I looked through the forum and didn't see a fix, or if I did I missed it. Thank you in advance for any help you can give me. I don't think I made a backup of the stock Nook 2.2.0 though.
