In Terminal, did you get a message confirming successful file transfer?
With Xposed & Gravity Box, I have a modified power button menu, including an option for rebooting to recovery.
My phone then rebboted into CWM recovery. Important: When rebooting from CWM recovery, don't forget to disable stock recovery, as the phone may attempt to return to it - CWM will ask you before shutting down.
Hope this helps!
