  • Hi, basically the operating system file source already available at your Samsung Galaxy S3, if you are doing hard reset using standard steps above, then usually the operating system will be reinstall although all data will be wipe or remote. However, this standard steps will not working properly if you ever do some tweaking or root or using custom ROM. That is why you should make sure your phone at standard non root default os or not. If you are sure, please try to do again hard reset but you have to use hardware button like steps at #Options 2 above.

  • Hi, after doing hard reset and erase all data at all storgae, it is very small possibility for us to recover old data at internal memory. However, for safety reasons, please do not give your external microSD to new user when you want to sell your phone. Better you buy new microSD if you want to sell include with microSD card.

  • Hi, if you already try to do hard reset but the problem still happen at your Samsung Galaxy S3, then there are several possibility that can make it happen, first you have to make sure your Samsung Galaxy S3 still at standard rom without Root or Custom ROM or any other tweak. Because hard reset or standard solutions will not work with it. If you are sure that your phone still never get any custom tweak, then you have to consult with Samsung authorize for hardware troubleshot.

  • Hi, if you forgot the screen lock protection at Samsung Galaxy S3, then you can try to unlock or bypass using Google account that you have already signed in before. Please try to give several time wrong answer continuously until your Samsung Galaxy S3 locked or freeze about 30 seconds, at this moment you will find Forgot Password / Pattern button, press this button, then you can give your Gmail username and password that you you have already signed in before. If you still can not unlock Samsung Galaxy S3 using Gmail account, then you have to do hard reset using hardware button combination key at #option 2 above.
