Hi. My brothers iPhone 4 battery died (1% and turned off). He put it on charge and everything and it just won't turn on.
We have also replaced the battery and still won't turn on.
Connected it to the computer and nothing. Held down the power button and middle button and left go to enter dfu mode.. The computer then finds it because it installs the drivers (screen still blank and no power). iTunes won't pick it up in dfu mode.. What's happened to it?
It's also jail broken but has been for ages and no problems
