    i have a situation like in the attached picture, i can't update the firmware of the standby partition. I tried both cloud and local solution.
    I found this solution in the forum
    https://community.zyxel.com/en/discussion/13011/recovery-steps-for-usg-flex-atp-series-with-device-has-firmware-update-fail/p1?new=1
    but the FW present on my device does not match

      Hi @DGTinfo

      I recommend taking a backup of your configuration. Additionally, try rebooting your device using the #1 partition (or enter following CLI command before rebooting device):

      > set firmware boot number 1

      Afterward, you can proceed with upgrading your device to the ZLD 5.36 Patch 2 firmware.

      downloaded the correct FW, I tried to update both from the web interface with a local path and via FTP, but it doesn't work.
      I also tried the procedure via USB, but in the SSH connection it returns me this error

      Hi Stanley,
      thanks for the advice
      At the moment I solved it like this:
      configuration backup
      booting the device from the outdated partition 1
      upgraded partition 2
      rebooting the device from partition 2
      configuration restore
      partition 1 upgrade

      NOTE
      the problem is that by restarting the device from partition 1 the credentials are not updated, luckily I was able to recover the password for this device
