    – don’t skip those steps.
    – NANDROID Backup is used for the already installed ROM as it sets a restore point for the device.
    – Factory Reset is required as you need to remove all data from the previously installed ROM before installing the new CM 11 M8 build.
  • if you want to save some data from installed apps or SMS text messages, then you should try to use the Helium tool for Android.
    – also you can sync Contacts and People details with your default Gmail account.
  • check the Galaxy S2 battery charge level and make sure that it is over 50%, this prevents the device from switching off during installation.
  • use this tutorial only if you’re an advanced user.
  • do not blame us in case you brick the phone or you lose any data in the process.
