It seems that when going through an upgrade, if CCA hangs, its already deleted the IOS and now when I reboot the UC520, its a brick. How do I get the IOS back on the flash?

When you type it without parameter, it shows the environment variables that you have to set, like IP_ADDRESS=10.10.10.10


When all variable are set correctly, it will proceed to copy file to flash, or there is an option to only load image and boot.

Can you type an example that actually works? I cannot find the right string.
