Q: Forgot pass code and want reset my device so how I can reset passcode

If you have a passcode to the screen lock that you've forgotten, restore the iPad from the computer to which the iPad is synced. For information and instructions, see:

If that will not work, you'll need to put the iPad into Recovery Mode and then try the Restore again:

If that still doesn't work, as a last resort try DFU mode:

There is no way to recover it apart from you remembering it. If you can't then you will need to connect the iPad to the computer that you normally sync to and you should then be able to reset the iPad and re-sync your content to it (http://support.apple.com/kb/HT1212) - you may need to put the iPad into recovery mode : http://support.apple.com/kb/ht1808

You can't recover your passcode. If you forgot it then you forgot it. You have to restore the device back to factory settings. If you try to reset all settings it's probably going to ask you for your passcode, which you don't remember. Yet another example of why people shouldn't set passcodes.
