Software developers of XDA Developers Forum have released the new Android 5.1 Lollipop custom ROM to the Samsung's 2013 flagship phablet Galaxy Note 3.

This new firmware has been created by a prolific developer, who goes by the moniker- arter97. It is based on the CyanogenMod [Unofficial] CM12.1 version. We would like to remind that this CM12.1 custom ROM is an experimental version and has some bugs, which need to be fixed. So readers are advised to read the whole tutorial thoroughly before going ahead with the custom ROM installation.

Prerequisites (Things to remember before installing the custom ROM):

  3. Installation of custom ROM requires clearing of memory in the smartphone, so make sure to back all the data by installing Clockwork Mod (CWM) Recovery/ TWRP in the smartphone.
