Working to boss gumana saken salamat hahahaI dont know if irs gonna work for you but it did work on me,
I forgot every details on my yahoo account even security question and answer, lost sim card registered etc.
Just login your yahoo account and the password you remember, 3 password you remember, just login every 1 2 or 3 hours and so on and everyday even months, just login! Yahoo will let it slide and will let you type your new password, Just Spam Spam Spam them! Hope it work on you too. Goodluck.
