Hard Resetting Samsung Galaxy Player

If you have forgotten your passcode lock and want to simply reset the device here are instructions

1. Power Down the device
2. Hold Power and Volume UP buttons at the same time
3. Once you see the Samsung logo, let go of the Power button but continue holding the Volume UP button
4. Soon device goes into a screen that gives you the option to restore factory settings
5. On the factory reset screen, I had to select the reset option twice because the first time around it asked for my password, which ofcourse was wrong. Selecting Reset again wiped the device.
6. Reboot device after wipe is complete

Android version was Gingerbread
