Hey, I have an iPhone 4 on Verizon CDMA. OK, I did not think charging an iPhone with bad chargers would render the iPhone in a state that whatever you do and anything you do it will not turn on at all and no entering DFU and iTunes will not even recognize it. So, I decided to see what message would show if any in redsn0w, and it says "*Connect acf2 device in normal mode". What does that mean? Is the motherboard blown out? Does the motherboard needs to be replaced?
