Yesterday I was trying to use redsn0w, iTunes, and a version of IOS 6.1.3 to restore my phone back to IOS 6.1.3 as I like it better than IOS 7. Anyway, since my power button doesn't work, I had to use redsn0w to make a "ENTER DFU" mode file so I could enter DFU. So after I made it I loaded it through iTunes and let it do its thing on my phone and I'm pretty sure that it was in the DFU mode loop thing (it was a black screen which is what it's supposed to be I believe) so I then tried to used redsn0w to install the IOS 6.1.3 IPSW file, it loaded on my computer and eventually just stopped and nothing was on my phone. Pretty much after that I couldn't turn on my phone (I usually plug it into my charger and it boots up) and is completely unresponsive. None of my computers recognize the device so I don't know what to do. I managed to get it apart and I have the back cover off. I tried sticking a piece of paper in between the button and everything but I can't get it to work. I have a feeling I bricked my phone some how and I really have NO CLUE what to do. Any help would be greatly appreciated.
Added (1). Oh and I want to point out that before I even attempted to install IOS 6.1.3 I restored my phone to factory settings.
