We show you how to factory reset the Samsung Galaxy S to clear all data and restore its original settings

The Samsung Galaxy S is highly customizable and you have been hard at work tweaking it to your liking, but now the fun is over and you want to return it to its factory settings again. Here, we show you how to hard reset the Samsung Galaxy S with step by step instructions.
Please note that all data will be deleted from the Samsung Galaxy S as a result of this procedure. This process does NOT delete data stored on the microSD card. We recommend backing up all of your personal data before proceeding.
First, try this:

If that doesn't work, or if your phone is frozen:

1. Turn the power off. If your Samsung Galaxy S is frozen, pull the battery out and reinsert it
2. Hold the Volume Down button

4. You are now presented with a menu that allows for Fastbook, Recovery, Clear Storage, and Simlock
5. Select Clear Storage by pressing the Volume Down button

If you selected YES, all data including third-party applications will be deleted from the Samsung Galaxy S. Once the wipe is complete, the phone will reboot to its factory fresh state.
