Then make sure you have a computer or a mac, and connect your iPhone via USB cable to your computer. If the operating system starts to install drivers, wait until the end of the process generally takes less than 2 minutes.
Make sure that: The phone is switched off and connected to the computer or mac. It is important to know that you have to do is a combination of power and home button keys.
- Press the Power button for 3 seconds. Without releasing the Power button, also press the Home button for 10 seconds (ie simultaneously). Release the Power button and continue to hold the Home button for 30 seconds.
