hello my friends,
Bauner (senior XDA member) has ported CM12 to the Old Galaxy Note GT-N7000. This rom CM12 n7000 or Nightowl as named by the community is unofficial CM12 currently received the 5th update Beta5 where almost everything is working exept recording at 720p and 1080p but using a third party camera app from the play store fixed the problem.
This rom is very smooth and stable, no more force close, random reboots, overheating or similar issues w've been facing in kitkat days.
I have posted a full guide on how to install cm12 n7000 which can be found in my blog www.droidtalk.net
