The CyanogenMod team has released the official CM 12 Nightly ROM for the Motorola Droid 4 smartphone. Check the info listed in this post if you want to learn how to successfully install a brand new custom Lollipop ROM for your device.

The CM 12 Nightly ROM is based on the Android 5.0.2 Lollipop AOSP builds, but it packs tons of other extra features in it too. Check the CyanogenMod team website here for more info on this release.

Before starting the installation process of this new ROM you should read the guidelines below:

  • use this post only with the Motorola Droid 4.
    – do not try to install the files that you will find in this post on any other different Android device.
  • your phone has to be rooted and running the latest build of either CWM or TWRP Custom Recovery.
    – the installed custom Recovery needs to be upgraded to its latest build so that it supports the installation of a brand new Android 5.x Lollipop ROM.
  • in the tutorial part of this post you will find two extra preparation steps like the NANDROID Backup and the Factory Reset.
    – the NANDROID Backup creates a restore point for the device, it can be used in case the new ROM doesn’t boot in normal mode.
    – the ‘factory reset’ wipes clean the system memory partition, it allows you to install the new CM 12 Nightly ROM on a clean partition by removing the old ROM.
    – ‘factory reset’ process doesn’t remove any data from installed applications.
  • if you need to save any data from installed apps, then you can try Helium for Android.
    – Contacts info and People details can be synced with your default Gmail account.
  • this is a guide for advanced user.
  • check the battery charge level of your device and make sure that it is over 50%, it will prevent the device from powering down during installation.
  • read the whole guide and don’t skip any steps.
  • we cannot be held responsible in case you end up losing any data nor in case you brick your device.

NOTE: after the CM 12 Nightly ROM is flashed you wish to continue using it, then you should know that you can keep updating it with new Nightlies using the newly created CyanogenMod Updates menu under Setting> About Device section.
