Are you interested in our Early Access Program (EAP)? This program allows you to preview code, test in your lab and provide feedback prior to General Availability (GA) release of all Infoblox products. If so, please click the link here.
You should open a support case for this; Infoblox support is best positioned to provide advice on appliance recovery. This is especially true if the appliance is currently providing DNS or DHCP service in production.
