Sonicwall Prol SOHO/10 Internet Security

[mindlord]

I recently found an old Sonicwall Pro firewall that was not functioning properly. I factory reset it and when I went to configure it, it told me "The current firmware file appears to be corrupted.". When I tried to add the serial on Sonicwall to get the new firmware it told me they no longer support this device. I cant find the firmware anywhere else, so does anyone know of a location where I can get said firmware or have it had hand?

Thanks in advance!
