My firewall is in Japanese or Chinese language after firmware upgrade.

This issue can occur after a firmware upgrade, where an incorrect firmware file is used.
The ‘’bin.sig’’ file shown below is Japanese.

NOTE: Manually changing the language to English will NOT resolve the issue.
Device Setting | Administration | LANGUAGE | Selection English
In order to go back to the original language, you will need upload the correct firmware to the firewall.
