Good-bye Android 4.4.4:
10/19/2018
As of October 2018, I have officially stopped supporting CyanogenMod 11 (Android 4.4.4) for the Nook HD & Nook HD+.
Due to no longer supported Android security patches by Google for this version of Android.
You can still get the September 2018 update of CyanogenMod 11 for theses devices that I made on xda-developers.com
