N2A Cards (R) - Transform your Nook Color into a Kit-Kat 4.4.2 Android Tablet (new 2014 version) - (8 GB)
I followed the directions on the paper that came with the card. So simple, I had more of a problem with putting the teeny tiny card into the teensy weensy slot than with installing it. I did not time it or rush, but it could not have taken more than 5 minutes. Great job. Highly recommended  .
