Semi-offline update:
Put the copy of the ISO image in the /root directory. Now run the "zk update" command. 4MLinux will now download only a very small info file (the ISO image in the /root directory will be used to update your system).

PS.
Theoretically speaking, you can also try to preform regular installation (using live CD/USB) without formatting the target partition.
