[MJ] Ok got your point. Then what would be the steps to return from Monitor to Hyp mode?

You can't do it directly. While still in the Secure world you set up the HVBAR and a suitable vector table for hyp mode exceptions. Then you can drop back into NS-SVC, and execute an HVC instruction which puts you into hyp mode at the hvc entry point in your vector table. See patch 7 in the series.
