Galaxy Note 3 is a lucky device to receive the latest Android 6.0 Marshmallow update. Although unofficial, the update comes in the form of CyanogenMod ROM with the upcoming version 13. The CM 13 sources are available and has been ported to the Galaxy Note 3 device. With the listed ROM, you can now update your Note 3 to Marshmallow. Not many changes have been made into the CM 13 source code. However, SuperSU has been added and the CM kernel source has been replaced with Temasek’s latest HLTE kernel source to support the CM ROM on the device.
The Marshmallow ROM seems to be stable, but several bugs prevail at the moment. Further updates are promised by the developer and bugs will be fixed. Even though the ROM may not look like a daily driver, it is a great deal for Android enthusiasts who want to test the latest Android software. You will need TWRP to install the ROM. If you have multi-ROM support, then you can try it as a secondary ROM. Read the bugs section before you proceed to install the ROM.
