Has the machine ever been restarted? If it still doesn't work, it may be that the SD card is damaged.

If the memory card is not broken, it may not be plugged in properly, and there may be something wrong with the mobile phone system. However, it is generally a problem with the memory card.

You can click the Next button in the lower right corner of the screen and follow the prompts of the setup wizard.
