Part of the text messages on Apple’s mobile phone suddenly disappeared

Because the phone was jailbroken and the information was deleted, the system can only be restored through iTunes.

1. Install iTunes. Launch iTunes.

2. Plug in the iPhone, press and hold the Power (power button) and Home (round button below) for 10 seconds, wait until the iPhone screen goes black (according to experience, it will be about 0.5-1 seconds after the screen goes black). Release the Power button and keep holding it until iTunes recognizes the iPhone.

3. At this time, Windows will first discover some new hardware and drive it by itself. After iTunes automatically recognizes the iPhone, a prompt box will pop up. "iTunes has detected an iPhone in recovery mode. You must restore this iPhone and then use it with iTunes." Click OK at this time.

4. Open itunes. On the section that displays the iPhone capacity and information, click Restore to start the recovery process.

5. Until the iPhone displays a data cable connection screen, iTunes prompts that the firmware recovery is completed.
