Reverting to a previous firmware version using the web-based manager
The following procedures revert the FortiGate unit to its factory default
configuration and deletes IPS custom signatures, web content lists, email filtering
lists, and changes to replacement messages.
Before beginning this procedure, it is recommended that you:
• back up the FortiGate unit configuration
• back up the IPS custom signatures
• back up web content and email filtering lists
For information, see the FortiGate Administration Guide.
If you are reverting to a previous FortiOS version (for example, reverting from
FortiOS v3.0 to FortiOS v2.80), you might not be able to restore the previous
configuration from the backup configuration file.
To revert to a previous firmware version using the web-based manager
1 Copy the firmware image file to the management computer.
2 Log into the FortiGate web-based manager.
3 Go to System > Status.
4 Under System Information > Firmware Version, select Update.
5 Type the path and filename of the firmware image file, or select Browse and locate
the file.
Note: Installing firmware replaces the current antivirus and attack definitions, along with the
definitions included with the firmware release you are installing. After you install new
firmware, make sure that antivirus and attack definitions are up to date. For details, see the
FortiGate Administration Guide.
Note: To use this procedure, you must log in using the admin administrator account, or an
administrator account that has system configuration read and write privileges.
