I received a new IPO and SD with 11.1, I am trying to downgrade it to 11.0 SP5 with no luck. I have taken the same process that I have for years to upgrade/downgrade systems. Loaded Admin 11.0 SP5 on my computer, Did a Format SD and Recreate SD. Everything completes successfully. When I put the card back in to the IP500 and it boots up. It shows it has V11.1 and as expected will not allow me to connect to it with the 11.0 Admin client. Any suggestions why it would not be keeping the 11.0 version I formatted and recreated the card with and reverts back to 11.1?
