Root [1st Gen] Kindle Fire Stuck in Splash Screen

[Mathlete]

Ok. Let me preface this with I know that there are many different forums/posts/discussions/whatevers concerning that the first generation Kindle Fire gets stuck in a bootloop. I have scoured the web and tried every solution I could find. The most recent one was using the soupkit to try and fix it. I even bought a factory cable to attempt to gain access to fastboot mode for the soupkit. With a normal USB cable, the soupkit recognizes the kindle fire with adb access. When I connect the factory cable, however, neither fastboot commands or adb commands work. The kindle fire has no animation at all and just stays at the white and orange kindle fire logo, regardless of a cable plugged in. The battery is charged, as indicated by the LED light and the fact that it will stay on when not connected to a power source. The kindle has been in this state for month, but if I recall correctly it was running Jelly Bean. Then, I was trying to get back to the stock Amazon OS. I flashed their files, but apparently that just bricked the kindle fire. Sorry for such a long post, but anything is worth trying at this point. I have access to all operating systems as far as computers go (Linux, Mac OSX, and Windows XP) Thank you in advance.
