How can I reinstall the system on an Apple phone?

Today, I was so crazy that I tried to restore the system from time to time due to software conflicts. I had to share some experience this afternoon.

1. the latest version of iTunes, the latest version of iTunes, and the latest version of iTunes must be installed on your computer. The important thing is to say three times.: http://www.apple.com/cn/itunes/download. if you have installed your shoes, upgrade them to the latest version. Then, check again to check whether the version installed on your computer is the same as the latest version on the official website. otherwise, manually uninstall the computer and reinstall it.

 

2. Open the latest installed version of iTunes and connect your mobile phone to your computer.

2.1 press the power key to start the instance. When the screen displays an apple icon, do not release the power key;
2.2 press and hold the Home Key of the Home screen until the screen is black;
2.3 when you see a black screen, release the power key and press the Home key on the Home screen until a restored iphone is detected in iTunes;

 

3. Click the "Restore iPhone" button in the iTunes window. If the mobile phone has important files, click the "Upgrade" button first.
