CM12 is in Development Stage for Galaxy Note N7000
Android 5.0 Lollipop will not be officially released by Samsung for its Galaxy Note N7000. So, the first Galaxy Note will be stuck on KitKat firmware since there are no plans implying a future Lollipop roll out. But, if you still want to test the latest Android release on your own phablet, you should panic as something good is being prepared for you. CM12 custom ROM is currently in development stage and a pre alpha variant of the software can be already downloaded and installed on your Samsung Galaxy Note N7000.
CyanogenMod 12 a.k.a CM12 is the latest built of CM, an extremely popular custom ROM designed to work on Android based devices. Like any other firmware version of CyanogenMod, CM 12 will bring both stock and extra Android 5.0 Lollipop features on your Galaxy Note, the custom ROM being fully optimized and customized for providing an improved Android experience and better performances, whether you are using a mid range or high end smartphone or tablet.
Thus, CM12 is not an official release of Lollipop OS. In fact the update is only based on stock Android 5.0 and has nothing to do with Samsung. In our case, those of xda-developers are developing a dedicated CM12 version for your Galaxy Note, just for providing you a proper update solution – as mentioned there won’t be any Lollipop OTA roll out for your Note, so flashing a custom ROM will be the only way in which you can get Android 5.0 software.
A pre alpha built of CM 12 is already available, but the ROM is currently having various bugs while most of features are still under development. Therefore, this release is only for testing phase and not for a daily use. Anyway, don’t worry as all the problems will be soon fixed and the devs will also provide a stable variant of the Lollipop update.
Remember that if you want to update your Galaxy Note N7000 with CM12, first you will have to root your phablet. Then you will have to install a custom recovery image on your phone as a custom update can be flashed only by using the latest version of CWM, TWRP or any other similar tools.
