Not interested in your other device, it has a specific forum, and you'll need to post a thread to that forum to get help with it. That's how things work around here, specific forums for specific devices as what works for one device doesn't necessarily work for another
And with regard to how to find that thread, navigate to the General section, and it's a stickied thread which means it's on the first page.
If you want your phone fixed, it's going to take a bit of effort on your part, and using menus to navigate to different parts of the site is something you're going to have to do (we have stickied threads so we don't have to constantly repost common stuff). Go to the root of Samsung Galaxy S II I9100 & it will list the different sections, you'll see the General section listed there.
If it's important enough to cause you grief if it's lost, back it up. No excuses
