IPhone 3G doesn't charge or turn on. (Whited00r iOS6 jailbreak)?

I was on my iPhone the other night and it was on 5% remaining battery, so I just pressed the lock key and set it down. Next morning I try to charge it and a red bar shows on the screen with a lightning bolt so I just left it sit for a couple of hours but nothing happens. I have tried every possible solution to fixing this like hard resetting, rebooting etc. NOTHING works. My computer doesn't even recognize the device. Is restoring my iPhone really the last resort? I don't wanna restore because then I will lose all of my data on my phone and I have ALOT of important stuff on it.

You broke it… It's bought it.
