Will this be the solution to fix my iPhone's problem booting up?

Will this be the solution to fix my iPhone's problem booting up? My iPhone is perfectly fine, but the firmware is not working; it is not loading the kernel in to memory, so I went to this site and this girl there advised me to do the following three instructions at this link: http://adf.ly/PywYa And my phone will work. It turns out that the instructions ruined my iPhone worse now and I want to track her down and sue her. Can anyone view the page and tell me if she is a scammer or not? I know this is the wrong place to ask this, bear with me, but please just check that out for me and help me ... I have lost over $600.00 on that phone, so please help....
