Currently, no. The short answer is grab the latest ISO and up2date it to the release before this mess of 9.352-6. Then you will have to restore the backup from your config file that matches the version.
Don't forget (like I did) to use the correct ISO and you must burn it to a CD or DVD rather than use a USB drive. The ISO's that start with asg are for software UTM installs on your own hardware and the ISO's that start with ssi are for the proprietary hardware appliances.
