Galaxy Note 3 gets Android Marshmallow with unofficial CyanogenMod 13 build
An official build of CyanogenMod 13 featuring Android Marshmallow is now available for the Galaxy Note 3. Based on the latest source of CyanogenMod, the custom build is rooted with Chainfire's SuperSU and a deodexed version of firmware.
XDA member Morningstar, the developer of the ROM, says although the CM13 build is stable, since it is still going through an experimental stage, it has several issues. The developer notes that call, message and mobile data do not work as the SIM card is not recognised, but the issue seems not related to the CM. If you want to make calls with this CM ROM, use Hangouts.
Apart from these, the external SD card does not work after formatting the stock CM file manager; Bluetooth and capacitive key backlight settings also do not work. The developer asserts that these will be fixed in due course.
In case you still want to try out this ROM, following is a guide for a step-by-step installation process. The CM13 build works with the Snapdragon powered Note 3 models which are N9005 or N9002. Do not use this on any other model. Also, you need TWRP recovery to install this custom firmware. Most importantly, do not forget to create a backup of all data of your phone.
