The port was released by XDA Senior Member madmack. It is an initial release, so it’s a little rough around the edges. As madmack notes:
Radio, audio, wifi, bluetooth and GPS should work. I haven’t had time to test this thing thoroughly so feedback is welcome!
The stylus doesn’t work. Need to investigate.
Dev talk: The device tree was forked from N7100. Most of the board share the same peripherals so it was a matter of getting the correct defconfig and the correct initramfs.
That should be encouraging for AT&T Note II owners, as many of the issues should be fixed relatively soon. Of course, as with most ports, there are likely to be a couple lingering issues. However, the majority of the issues should be fixed soon. This is also good news for the other US variants of the Galaxy Note II. Because they share largely the same hardware, getting this ported to the other versions should be a relatively simple task.
