Procedure

  1. Run the dir command to check the file system.

    • If the storage medium is unavailable, the storage medium is corrupted. Go to step 2.
    • If the software that fails to start the system is in the file system, check the file size. If the file size is not in the allowed range, the system software is invalid. Go to step 3.
    • If the storage medium is available and the file size is within the allowed range, system software is faulty and cannot start the system. Go to step 4.

  2. Check the storage medium saved in the system software.

    • If the storage medium is an SD card or a USB flash drive, replace it and perform an upgrade again. If the upgrade fails, go to step 4.
    • If the storage medium is flash, record the device type and number and contact technical support personnel.

  3. Delete the invalid file, upload a complete file, and then perform the upgrade. If the upgrade fails, go to step 4.
  4. Collect operation results and contact technical support personnel.
