Thanks for creating and sharing your builds with us. CM-11-20140115,is smooth as silk, so far I haven't noticed any flickering or lags as opposed to 01/17.
As for the automatic reboot bug, this seems to work: I plug the charger to a wall outlet, connect it to the nook and power it down(it doesn't automatically turn back on).But when i turn it off without a charger plugged in, it automatically reboots.
So for now, i guess I have to plug the charger in each time i want to shut the device down. Other than that, this is the perfect rom for use as a daily driver.
Edit: With 3c toolbox, i can completely shutdown now with or without a charger.
