I didn’t know if it would ever happen, but experimental nightly builds for Android 4.4 (Kit Kat) have arrived for the venerable Nook Color. I installed it tonight.
Since I’ve previously run other versions of Cyanogenmod on the Nook Color, the upgrade was pretty straightforward. I had to reboot to recovery, update my recovery because my existing recovery was old and incompatible, reboot again (to recovery of course), which put me in Clockworkmod 184.108.40.206, and from there I installed the Cyanogenmod 11 zip followed by the Google Apps zip.
Newly flashed Android devices sometimes take some time to settle in before they’re really usable. On this 1 GHz, 512MB device, Kit Kat does seem faster than any of the Jelly Bean builds (Android 4.1-4.3) I’ve tried to run on it, but it’s not as quick as my Samsung Galaxy S 4G running Android 4.0.4. I’ll give it a little time.
