Could you explain how you even got a recovery drive? I have gone through this process so many times and it NEVER has made a viable recovery drive. The only thing in my recovery drive is a folder named "com.apple.recovery.boot". Really wish I could get this to work.Boot to USB installer and run post-install found in the "Utilities" section of the menu bar.

macOS 10.12.2 isn't yet available. Try resetting Catalog option using AUSEnabler. Then run MASmto check for iTunes update. Worked for me.

Actually SIP doesn't have to be disabled... at least that has been my experience. It only seems to matter when doing OS updates. Tried with/without SIP and this seems to be true.You need to re-run my post-install tool and ensure that SIP is disabled.
