Had been using this on my Rooted Nook Color and seems it is no longer working. been getting a number of different errors, some of which come and go but generlaly don't persist, but regardless, ads keep showing up in apps that don't show ads on my DINC counyterpart.
The errors I get are:
Failed to remove /system/etc hosts so it could be replaced
And one more I can't seem to recreate. I've had the error happen on 2 Nook Colors, one fresh out of box and rooted clean.
