Sprint Galaxy Note 4 has now gained official nightlies support for the CM12.1 ROM, meaning, from now on you’ll be on the bleeding edge of latest updates to CM12.1 available for your Sprint Note 4.

Installing CM12.1 nightlies is easier, you download the CM12.1 ROM, boot into TWRP recovery, flash the CM12.1 zip file and wipe data / factory reset your phone. Also, along with that flash a compatible Gapps package for enjoying Google services.

If you’re installing a custom ROM for the first time though, you might need detailed assistance for all that. Below are detailed step-by-step instructions to install CM12.1 on your Sprint Note 4.

Step 1: Install TWRP Recovery

This will trip the knox counter and hence void warranty.
