  • In order to successfully install the new AOKP M2 ROM, you will first be forced to apply a factory reset for your device, which means that you will lose all the data from the system partition. This means that all installed apps data, SMS and other similar files will be removed in the process.
  • Factory Reset will not affect the internal / external SDcard contents.
  • If you want to backup installed apps data, then you should look for a working tool at Google’s Play Store.
  • To backup SMS, Call Logs info and other similar data then you can use the following tools for Android: SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore. Root access is required for some of these apps.
  • Make sure to sync your Contacts info with the Gmail account you’ve assigned as default for your Galaxy S3. This action will act as cover in case you lose any save phone numbers or contacts data in the process.
