New firmware doesn't upload if the file is incompatible or corrupt, or if the hardware doesn't have the standard configuration.

Wrong or incompatible firmware image.

You're uploading a firmware image that's incompatible with the active version.

What to do

Go to Firewall Installers to see compatible versions for the device.

Incorrect firmware image or appliance hardware.

Cause

The appliance (hardware, virtual, or software) hardware configuration doesn't meet the firmware requirements.

What to do

Corrupt firmware

Cause

The firmware is corrupt.

What to do

Use a different firmware version. Alternatively, download the firmware image from Firewall Installers and move Sophos Firewall to it.
