The Yunqi community editor reminds you that using itunes to upgrade ios7 on your computer will clear the data on your mobile phone and help you back up the data on your mobile phone before the upgrade.

1. Download the latest firmware version of the mobile phone model corresponding to iOS7.1.2 (direct upgrade of iTunes is not recommended because the firmware download speed of iTunes is very slow ).

2. Connect your iPhone/iPad/iTouch to your computer and open iTunes.
3. Press Shift on the keyboard and click the left mouse button to update/restore iTunes.
4. A dialog window will pop up in iTunes. Select iOS7.1.2 firmware and click Update to wait for iTunes to run.
5. To successfully upgrade/restore iOS7.1.2, activate the device. Follow the system prompts to complete the steps.


Tip:

Some friends prefer to directly update the system on their mobile phones. This update will not affect the data on the mobile phone, but may cause the SHSH to be unavailable, at the same time, some friends who use ota update said that the mobile phone upgrade is unstable. At the same time, the iPhone, iPad, and iTouch that have been jailbroken may not be able to use the OTA update method.
