3. Try re-burning the SD card, this may be caused by a file loss due to a faulty SD card.

    In a later version, we will add SD card status alerts to the web dashboard. This will alert you to the abnormal status of the SD card, which can cause all sorts of strange system failures.

    SD card failure solutions:

        Please open the link below to download the firmware file  and Operating  documentation. Then burn the SD card.


Tip. 1: The system needs to continue with certain installation steps when you first boot up, this is automatic, but please do not power down within 5 minutes of first boot.

Tip. 2:  If you have more than one device, please burn the SD card separately. Once the SD card has been inserted into the device and powered up, it will write the device information and cannot be replaced directly for use in other devices. It is also not possible to copy SD cards from other hotspots for use.

4.If the device has been online for more than 8 hours after re-burning the SD card and still cannot be upgraded to the latest version. 

    It is recommended to purchase a new SD card to replace it. 

    10MB/sec + 32G or above SD card can meet the system requirements.
