I have a HDX 6000 has is crashing from time to time. I don't have a support contract but I'd like to just re-install the current version of the software on the HDX. My problem is the current version is 220.127.116.11_00_cisco-3966 and it's not listed on the downloads site. I checked the install guide for 18.104.22.168_1 and the link to download the Cisco version listed here doesn't work anymore. Does anyone know where I can get 22.214.171.124_00_cisco-3966?
