Maybe he just typed it wrong and meant iOS 7.0.5.
Don't know what DFU means? The phone won't turn on at all. It's dead.can you get your phone into DFU mode?
is there any response when you plug in your phone to a charging source?
regardless DFU mode:
Entering DFU Mode (Official Instructions)
- Plug your device into your computer.
- Turn off the device.
- Hold the Power button for 3 seconds
- Hold the Home button without releasing the Power button for 10 seconds
- Release the Power Button but keep holding the Home button
- Keep holding the Home button until you are alerted by iTunes saying that it has detected a device in Recovery Mode
Thanks so much, this worked! There was no response when plugging into a charging source but by plugging into the laptop to charge and trying your method above, the message came up that the recover boot driver was not installed. So by applying your method above I ended up being able to reboot the phone, restore factory settings first, then restore from back up. It took some time but it worked. Thanks again, very much appreciated. It was a work issue phone too so you've helped me out no end!
