Before starting the installation of CM 11 M9 Snapshot ROM on your phone you will first need to read the guidelines listed below:

  • use this post only with the Google Nexus 5 smartphone.
    – do not attempt to update any other Android devices with the files that you will find in this post.
  • your Nexus 5 has to be rooted and running the latest CWM or TWRP Recovery image.
    – both CWM and TWRP custom Recoveries will work will this guide.
  • in the ‘how-to’ part of this guide you will find two extra preparation steps: the NANDROID Backup and Factory Reset.
    – do not skip these steps.
    – the NANDROID Backup: this one creates a full restore point for your phone, one that you can use in case the new CM 11 M9 ROM doesn’t boot in normal mode.
    – Factory Reset: this step is required so that you will get rid of all files installed by the previous ROM.
    – Factory Reset will wipe the system memory clean, but it won’t affect the internal storage of your device.
    – in case your Nexus 5 already sports a previous build of CM 11 M-Snapshot or a CM 11 Nightly, then you can skip this step and install CM 11 M9 Snapshot over them.
  • if you want to save data from installed applications, SMS Text Messages or any other files then you can use Helium for Android.
    – also, you can sync Contacts with your default Gmail account.
  • check the Nexus 5 battery charge level and makes sure that it is over 50%, this will prevent the smartphone from switching off during installation.
  • read the entire guide and do not skip any steps listed in the tutorial.
  • this post should be applied by advanced users who wish to tinker with their phone’s OS.
  • note that we cannot be blamed in case you brick the phone, nor in case you end up losing any data in the process.

Since you’ve read all of the above, you can now continue to the next part of this post and learn how to flash a custom ROM for your smartphone.

How to install CM 11 M9 Android 4.4.4 ROM for Nexus 5:

  1. Download the CM 11 M9 Snapshot ROM zip from here.
  2. Download Gapps for Android 4.4.x ROMs from here.
  3. Connect your phone to your computer using the USB cable and move both zip files on to its internal storage.
    – do not unzip the files and disconnect the phone from PC after the files are copied.
    – if you’ve used your Nexus 5 to download the ROM and Gapps zips, then you can skip this step.

    – TWRP: press Backup.

    – note that the first boot process will take a while before it loads all the new files, don’t press any buttons until you see the home screen of your device.

After the ‘factory reset’ you will have to apply a ‘format /system’ operation and then the tutorial will work.
