Do you want to enjoy Android 5.1.1 on your Sprint Galaxy Note 2 L900? You can do that through the CM12.1 ROM, so what are you waiting for? Although I am talking about nothing more than an unofficial builds compiled from CyanogenMod sources, let me tell you that it is really stable, being ideal for a daily use.

However, you cannot jump to the actual CM 12.1 update procedure and skip the preparatory steps as you risk damaging or bricking your Sprint Note 2: for the start, don’t forget to make a backup and enable the USB Debugging before starting the installation process.

If you don’t know, the USB Debugging can be found under Developer Options and if it’s not there, then you need to enable it by going to Settings> About Device> find Build Number and tap on it no less than 7 times. Then, it’s time to go back to Settings, open Developer Options and then enable USB Debugging.

Your Galaxy Note 2 has to be running a rooted firmware and even more, a custom Recovery should also be installed on your device; it can be CWM, TWRP or any other choice that you might have in mind, but the installed custom Recovery has to be updated to its latest version in order to support the CM 12.1 stable Android 5.1.1 custom ROM installations.

Check the device’s battery charge level and make sure that it is over 60%, as it prevents it from powering down during installation and don’t forget to prepare your PC as well by installing the drivers and deactivating the antivirus protection. Use this post only for the Sprint Galaxy Note 2 device; to be more specific, your phone’s model number should be L900. If it is not, then I can assure you that this procedure is not for you.
