y000000000000.boot and encrypted config files

[kapetrosyan]

Hello,
Currently, I'm using an old auto-provisioning mechanism.
Now I'm trying to switch to new mechanism, but the phone is not requesting mac_Security.enc files after downloading y000000000000.boot file.
Here is my .boot file. Please help
