1. After connecting the computer to the iphone, and then turning on the itunes software to back up the data in the phone, we're all talking to itunes's recovery model:
First, in the Apple 5s we press the "power button" and then shut down;
Second, then the boot then press and hold the power supply, but not loose until the white Apple;
Third, we hold down the home button, until the screen dark screen oh;
Four, okay, cell phone black screen we hold down the power of the bar, but also to press the home button in general to the itunes appears to detect a recovery mode of the iphone can be released.
2. As shown in the following illustration, we will see a "Restore IPhone" in itunes.
3. So itunes will automatically help me restore the latest Apple system, before this will be prompted to click the "Restore" button to continue
4. So our itunes will help me download the latest version of the iOS system installed on the Apple phone, the installation of a step-by-step following the prompts to operate the phone can be restored.
Friendship hint, I have some people on the internet said a day will be good, in fact, only in this way can let your Apple phone normal use OH.
