Samsung Galaxy S II Hard Reset [How To]

By  |  12 Comments

So you want to sell your Galaxy S II or return it but you don’t want to leave your data for others to find? Here’s how to ensure that it’s gone.

Don’t laugh, I’ve been reviewing smartphones for years and I could write a short book telling all the funny goodies I’ve found on phones because people didn’t take the time to remove their personal data.  I had one that must have been used by the PR rep that sent me the unit since they left their contacts on it and the contents read like a who’s who of mobile blogging. I had the personal data of a financial analyst from the Wall Street Journal a few years back. I also found a memory card full of music, photos, and even some NSFW video. These are people that should have all known how to protect their data. I never used any of this data for evil, I’d just wipe that data for them.

So, that said… On to the show.

Here’s a quick video I did to demonstrate how to do a hardware hard reset on the Samsung Galaxy S II Skyrocket. This same method works for all of last year’s Samsung Galaxy models like the Fascinate and Captivate. It also works for this year’s Galaxy S II models.

If you have any questions on how to do a reset on other models, feel free to contact me.

    Why go thru these steps when you can just factory reset from sttings menu?  Is there some sort of advantage? I don’t get it.  If there is an advantage, it wasn’t explained as far as I could see.

      In the video, I explained. Maybe someone hosed it up where it won’t boot. Maybe someone forgot their password or security swipe and can’t get back in. Sure, it’s easier if you have access to the software method. The end result is the same.

    I really just can’t get it done myself properly. Thanks for the video I’d be able to see it in action and compare it.
