Zywall 110 Firmware Update 4.71 to 4.72 or 4.73

saha76

We have a Zywall 110 with firmware 4.71. Can't upgrade to the next firmware. The file download passes, but the zywall does not reboot and the firmware does not melt. Try through the cloud and upload the file through the web interface. What can be wrong?

Zywall works. It's loading. Recovery is not required. It doesn't refresh.
