Install CM.12 Android 5.1.1 Stable ROM for Motorola Droid Mini, Ultra and MAXX

Use this post if you want to learn how to successfully install a brand new CM 12.1 Stable ROM for your smartphone.

The CM 12.1 Stable builds are based on the AOSP Android 5.1.1 Lollipop releases and they’re featuring all the vanilla Android functions as well as tons of extra CyanogenMod-based tools and apps. If you want to learn more about this release, then you should check the CM blog web page here.

Before starting the installation you should read these guidelines:

  • use this post only with the Motorola Droid Mini, Ultra or Maxx devices.
    – this guide works for the Motorola devices with the following model numbers only: XT1030, XT1080, XT1080m.
    – do not attempt to update any other devices with the files that you will find in this post.
  • your device has to be rooted and running a brand new Custom Recovery like CWM or TWRP.
    – the installed custom Recovery has to be updated to its latest build, so that it supports the latest Android 5.1.1 custom ROMs.
  • in the tutorial you will find two extra preparation steps: the NANDROID Backup and the Factory Reset.
    – do not skip those actions when you reach them.
    – the NANDROID Backup creates a full restore point for the phone.
    – the restore point can be used to fix your device in case the CM 12.1 ROM refuses to boot after the installation is done.
    – the ‘factory reset’ will remove the old ROM and make room for the new CM 12.1 Stable build.
    – factory reset doesn’t remove any files from your phone’s internal storage.
    – the factory reset is going to remove all the installation apps.
  • if you need to save data from applications, then you can try the Helium app for Android.
    – also, sync Contacts info with your default Google account before starting the installation.
  • use this post only if you are an advanced user, we cannot be blamed in case you brick your device nor in case you lose any data files.
  • check the battery charge level of your device, it has to be over 50% for it not to power off during installation or first boot process.
  • read the whole post first and don’t skip any steps if you want to complete the installation without too much effort.

If you like how CM 12.1 Stable ROM works with your device, then you can keep flashing new CM 12.1 builds using the CyanogenMod Updates menu under the Settings> About Phone section.
