This tutorial is for people who have tried formatting their phone using Hard Reset from the Settings menu but to no avail. I have formatted my phone using this method. So here goes;

- Make sure the battery is fully charged
- Back up data because everything will be wiped out!
- Turn on the phone and quickly press and hold the Dial & End Call buttons until you see a format screen
- Dial Button is for format while End call button is for cancel
- That's it!

NOTE:
You can also use this method to format other Samsung phones that doesn't have keypad like Samsung i907 Omnia, i910 Omnia, i8000 Omnia II, Pixon etc.
