VDPconfig failed to upgrade the device program

1. Check the failure prompt. Make sure that the network is connected. If the password is incorrect, you need to modify the device password in the settings.
2. If it reminds that fail to clear configuration, you can choose not to clear the configuration and restore the default or clear configuration with CRT after the program is upgraded.
3. If the upgrade failure is directly prompted, we can only upgrade with CRT.
