1. In this case we can try to reboot the 5s mobile phone, while pressing the "Power and Home" button, to maintain more than 5 seconds to see if it can return to normal, if we can not recover the Apple mobile phone system may be damaged, this time we only have to restore the system again.
2. Let's make sure that itunes is installed on the computer and then connect the Apple phone to the computer, and then open the itunes software on the computer.
3. After the iphone is connected to itunes, itunes should be prompted to currently detect a recovery-mode iphone
①, okay, now we're going to hold down Apple 5s's "power button and home button."
②, until the iTunes tip on the computer detects an iPhone in recovery mode
4. Now we'll click on the "Restore iphone" button on the itunes tip screen.
5. Then our itunes will give us a system suitable for our iphone5s, wait for the prompt after we click the "Restore" button, as shown in the picture
6. Because we are directly using itunes to download the system from the server and then install in our 5s, so the time will be longer oh.
7. The final step, if our system is restored, just activate the system once
Friendship tips, this recovery after the mobile phone data will be all lost oh, this is no way to avoid things oh.
