After T-Mobile, now the International model of Samsung Galaxy Note 4 is receiving the Nightly built of CM 12.1. Thus, the official CyanogenMod Android 5.1 Lollipop update can be now installed on your own Android device. So, what do you say, are you ready to learn how to complete this update operation?

If you do want to try the new CM12.1 Nightly ROM on your own International Galaxy Note 4, then don’t think twice and read all the guidelines from below. In this way you will learn how to properly apply the ROM in order to avoid unpleasant situations from taking place. You will also learn how to prepare your device for the update process and what to expect from the new CyanogenMod release.

First, CM12.1 Nightly is the official CyanogenMod ROM available for your Note 4. So, in a few words, the Android 5.1 Lollipop update is stable and smooth – you will definitely be able to use all the features and apps without dealing with bugs, lags or with any other problems. But, on the other hand, it will have to be clear for you that you are still going to use and install a custom ROM, which is not an official Android update.

Therefore, the ROM is developed by third party devs and has nothing to do with OTAs released by Samsung or by Google. So, you are just going to complete an unofficial operation, which implies in losing your Galaxy Note 4 warranty.

Also, you will have to prepare your phone before being able to apply the lines from below. In that matter you must know that this guide can be completed only if your Galaxy Note 4 is rooted and installed with a custom recovery image – I recommend you to use CWM or TWRP recovery in order to ease your work. Do ensure these two processes, or else don’t even bother – if you skip something or if you mess things up, then you can brick your device – since the warranty is lost, you will have to manually fix your bricked Android smartphone.

Backup your data because a hard reset process will have to be applied during the installation guide from below. Save everything that’s on your phone’s internal storage memory or else you will lose your personal data, info and accounts. Moreover, use the custom recovery image and make a Nandroid backup for being able to save / restore the current ROM that is featured on your device.
