That’s why I’ve created this post, for you to learn how to successfully restore your device to an official Gingebread firmware.

In order to make sure that you successfully complete this guide, you need to read the preparation guide below:

  • Use the tutorial only for the Samsung Galaxy S Advance model number I9070. Both 8GB and 16GB versions are supported by this guide.
