Cannot restore factory defaults after using 11.5

Dears, I have upgraded my F5 appliances to the new software 11.5 which was releases three days ago , after that the active/standby appliances didn't see each other and they both appear as disconnected and the provisioning was disappeared and i cannot see any of the modules.

I'm trying to reset one of them to the factory defaults , however, when i load the default config i get:

Loading configuration... /defaults/defaults.scf Resetting trust domain... Unexpected Error: MCP must be in the running phase to reset the trust domain. Examine the output of

tmsh show sys mcp-state

for failures.

root@(localhost)(cfg-sync Standalone)(Offline)(/Common)(tmos) show sys mcp-state

Sys::mcpd State:

Running Phase platform Last Configuration Load Status full-config-load-succeed

but now i cannot configure the network section as it gives me the following error: An error has occurred while trying to process your request.

please advise. Ahmad.
