CvzSistemi

I try to upgrade a USG1900 with running Version v4.72(AAPL.0) and standby version v4.39(AAPL.0) but it rollback.

I try with running partition to upgrade to 4.73 but it fail.

I try with standby partition to upgrade to 4.62 but it fail.

I try factory reset and upgrade but same result, update fails.

how to upgrade?

Hi @CvzSistemi

I recommend taking a backup of your configuration. Additionally, try rebooting your device to standby partition.

Afterward, you can proceed with upgrading your device to the ZLD 4.73 Patch 2 firmware.
