Update Galaxy Nexus I9250 to Android 4.4.4 with CM 11 M8 Stable ROM

Flash CM 11 KitKat ROM for Galaxy Nexus

Galaxy Nexus I9250 can now be updated to a stable custom Android 4.4.4 build using the latest M8 CyanogenMod 11 Snapshot ROM.

Read the whole article if you want to learn how to successfully install this ROM on your phone. This is the first stable build of CM 11 that’s based on Android 4.4.4 KitKat and if you’re a fan on CyanogenMod team ROMs then you should install this snapshot milestone build instead on the Nightlies.

More info about this release can be found here or here.

Read the guidelines below before starting the updating process:

  • install this CM 11 M8 Snapshot ROM only for the Samsung Galaxy Nexus GSM model number I9250.
    – check your device’s model number under Settings> About Phone.
    – if the I9250 model version is not listed then you should close this guide.
    – do not attempt to install this new ROM on any other Android device.
  • use this guide only if your phone is rooted and it’s running a custom Recovery like CWM or TWRP.
  • in the ‘how-to’ part of this post you will find two additional steps: one tells you to apply a NANDROID ROM Backup and another to apply the ‘factory reset’ for your phone.
    – by creating a NANDROID Backup file of the installed ROM you will set a restore point, this will allow you to repair your device in case the newly installed CM 11 M8 build doesn’t boot correctly.
    – ‘factory reset’ is required if you want to get rid of all the files installed by the currently installed ROM.
  • in case you wish to save some data from installed apps, SMS text messages or any other file, then you can Helium app.
    – also, make sure to sync Contacts and People details with your default Gmail account.
  • enable USB Debugging from Developer Options menu.
  • read the whole guide and don’t skip any steps if you want to install the new ROM at your first attempt.
  • note that this guide has to be applied by advanced users, do not blame us if you brick the phone nor in case you end up losing any data files.
  • check the phone’s battery charge level and make sure that it is over 50%, this will prevent it from switching off in the middle of the installation.

Since you’ve read all of the above you can now continue to the next part of this post.

Note that this new ROM is based on the latest KitKat 4.4.4 build and it might not be very battery-friendly, so you might get only a couple of hours of extensive usage out of your device after installation.
