How To Reset Samsung Galaxy Mini 2 S6500

- I used pattern lock, then someone tried to break it, then it locked and I need to sign in using Google account.
- The worse thing is, I forgot the Google account that I use with it.
- Done a few search using Google, related keyword 'how to unlock pattern lock android', 'galaxy mini pattern lock', 'how to reset galaxy mini 2', 'how to reset samsung s6500'.
- Found this site, said to reset Galaxy Mini 2 by power off the phone, press VOLUME DOWN + HOME + POWER, not working.
- Found this info from XDA, related to recovery menu. I try VOLUME UP + VOLUME DOWN + HOME + POWER. Working, boot into recovery mode.
- Select wipe data/factory reset. Working.
- Note: From the XDA site, it said to press VOLUME UP + HOME + POWER to enter recovery mode, I think that is the right combination key.
