Iphonex suddenly shut down, and then Apple's logo appeared. What happened?

First, the iphone doesn't turn on and keeps displaying white apples, indicating that the system has crashed. It is recommended to restore the system.

Second, the specific operation method:

1, download and install the latest version of itunes software on your computer, and open itunes after installation.

2. Connect the iPhone to the computer with a USB cable, and then you will hear a prompt that the computer is connected successfully.

Please turn off the iPhone now, and then you will hear the prompt that the computer connection is unsuccessful.

4. Please press and hold the ON key and the home key at the same time until the first 10 second. Please release the on button immediately and keep pressing the home button.

5. At this time, iTunes will automatically start and prompt for recovery mode (iPhone will always be black). Then you can press and hold the shift key on the keyboard, click "Restore" and select the corresponding firmware to restore.
