I downloaded N2a card's Jellybean and installed on my own Sd card for my Nook HD+ and it worked great. On March 1, 2016 I downloaded their upgrade to KitKat 4.4.4 for Nook HD+ and I have never been able to use it. Many support emails back and forth with n2a have resolved nothing. IF it boots at all, the settings will not keep saved at all and the setting for DISPLAY does not work at all and shuts down the entire program every time. Any insight to this will be much appreciated. Thanks much!
