IPhone won't restore? Forgotten passcode?

I forgot my passcode for my iPhone 4s. I have tried to restore it, but it keeps saying that the phone has a passcode on it and and you need to get rid of it before you can restore it. But because I have forgotten the passcode, I can't do it this way. But when ever I try and do it through DFU mode, the same message still comes up half way through 'extracting files'… Any other ways?

Happened to me too you go on the site an it will till u rite down all ur apps your gonna bomb that thing an erase everything
