Fortigate 30d Factory Reset Full

This is the gold standard. It works even when the device is bricked, stuck in boot loop, or has a corrupted filesystem.

This clears all settings and reboots to factory defaults.
Caution: Do not power off during the process.

Verify: Connect to https://192.168.1.99 (default). Login: admin (no password). You will see the initial setup wizard.

The factory reset may revert to an ancient firmware version. Check for the last available firmware for the 30D (v5.4.12 or v5.6.x, if still accessible via Fortinet’s legacy archive). Upgrade via System > Firmware. fortigate 30d factory reset full

Use this if the reset button fails, the device is stuck in a boot loop, or you want to wipe and reinstall the firmware (the most "full" reset possible).

Requirements:

Steps:

  • The firmware will upload and flash. After completion, the FortiGate reboots automatically.
  • Post-reset: It will be at factory defaults (192.168.1.99, admin/no password). Optionally, run execute factoryreset from the CLI after boot for double measure.
  • Select reset/format. Confirm.
  • Reboot device.

    • Notes:

    At the BIOS# prompt, type the following commands exactly:

    BIOS# reset all-settings

    The system will ask for confirmation. Type y and press Enter. This is the gold standard

    Next, to ensure no residual scripts or ACLs remain:

    BIOS# format bootdevice

    Again, confirm with y.

    Finally, to restore the original partition table and firmware checksums: Verify: Connect to https://192

    BIOS# exec factoryreset

    If the FortiGate 30D does not boot properly—stuck at "Loading..." or in a continuous reboot cycle—you need to interrupt the boot process and initiate a reset from the bootloader. This is the most thorough reset, often called a "maintenance mode reset."

    After reboot, the device reverts to factory settings. Limitation: If the previous owner disabled the reset button via config system admin or the OS is corrupted, this method will fail.
