Will iPhone 4 turn on if Dock flex cable is disconnected
With the iPhone turned off.
If you have a working iPhone 4 and you take off the back glass and disconnect the dock flex cable from the motherboard and the battery is fully connected and charged.
Will the iPhone turn on if you push the power button?
I realize that you cannot plug in the usb or charger because the cable is disconnected.
I don't have a iPhone 4 or I would try it myself.
