ZyWall USG 40, Unable to upate to 4.73, Checksum Error

WebWorks

I try to update a USG 40, from 4.72 (running) to 4.73.
The StandBy is V. 4.39.
Direct Update gives Error: Firmware update fail – checksum error, code: 400
Manual Update by FileUpload results in a reboot, but Update fails and version remains 4.72.
Do you have some more ideas? I have this problem on two devices.

My USG40 updated fine...did you unzip the .bin file?

Could also be your StandBy is too old?

@WebWorks the standby version is pretty... stale.
If you have 4.60/4.65 around you could do an update of the standby. Then update again to 4.73

Consider as precaution to reboot the device before trying to update and continue to use the 4.72 version until the standby goes to 4.73.

Hi @WebWorks,
It could be firmware corruption in running partition.

Please follow steps below to update firmware.(assume running partition is on partition 2)

1) Backup partition 2(current running partition) startup configuration file.

2) Reboot on partition 1.(Switch running partition from 2 to 1)

3) Update firmware on partition 1.

4) Apply 1) configuration file on partition 1.
