Samsung Galaxy Note for AT&T has just received its first beta version of CyanogenMod ROM, it is based on the Android 4.0 build developed by Hacksung team, currently this ROM run smoothly, but the FM and GPS does not work, because the DSP Manager also does not normally work, the media playback can’t be used, USB OTG or MHL is not in normal work, therefore currently we don’t recommend Galaxy Notes users to flash this ROM.
If you are not in the least afraid of the trouble and want to enjoy the non perfect OS, you can try it to follow the instructions of how to getting the test version of Android 4.0 CyanogenMod 9 ROM below:
