My has had some problems since i jailbroke it. ive been tring to reset it but refuses to turn correctly. what i mean by that is that it turns on if i hold the power button but it stays at the apple screen and doesnt go anywhere. every now and then it will come back and work. if i try to go into DFU the apple screen just turns off and on. plugging in my iphone to the wall or computer does nothing it doesnt appear on the computer or in the itunes. so basically i have run out of options i just want to completely restore the ipod back to factory settings and i need some help on how to do this please. thank you
