CM 11 Snapshot ROM is now live for the Samsung Galaxy S2 I9100G smartphones. If you are looking for a stable Android 4.4.4 custom ROM, then this build is the one that you should install on your device.

This new custom ROM contains all the AOSP Android 4.4.4 features and functions along with tons of extra CyanogenMod features and functions. Read more about this release here at the CM website.

This CM 11 Snapshot build is the final stable build that's based on Android 4.4.4. From now on we can only hope that the Galaxy S2 I9100G will see future CM builds based on Android 5.1 or Android M released for it.

Check the guidelines below before starting the installation process of this new ROM:

  • use this post only with the Samsung Galaxy S2 I9100G.
    - do not try to flash the files that you will find in post for any other different devices.
    - check the model number of your phone under Settings> About Phone.
    - if the I9100G version is not listed under About Phone, then you cannot use this post.
  • your phone needs to be rooted and running a custom Recovery image such as CWM or TWRP.
    - make sure that the installed custom Recovery is updated to its latest version in order to support the installation of a brand new Android 4.4.4-based ROM.
  • in the tutorial part of this post you will find two extra preparation steps: the NANDROID backup and the Factory Reset.
    - the NANDROID Backup creates a full restore point for your device, one that can be used in case the new ROM doesn't boot in normal mode.
    - the Factory Reset process wipes clean the system memory partition removing all the data installed by the previous ROM.
    - factory resetting the phone allows you to clean install a brand new CM 11 ROM without worrying that it won't boot in normal mode.
    - the 'factory reset' doesn't delete any files from internal nor external storage.
    - do not skip these steps.
  • if you wish to save data from installed applications, then you should use the Helium app for Android.
    - Titanium Backup doesn't work with CM-based ROMs.
    - Contacts and People details can be easily synced with your default Gmail account.
  • check your device battery level, it has to be over 50% before starting the CM 11 installation.
  • read the whole guide and do not skip any steps.
  • note that we can't be blamed for bricking your device and we aren't responsible in case you lose any important data in the process.

These were all the steps that you had to take in order to see if your phone meets the requirements for the CM 11 ROM installation.
