Help with TC Electronics G-Major - Basic Setup and Exiting M

[theDogger]

So I just purchased what is a brand new G-Major. Local producer bought it for a session and never used it. So I made him a 2x12 cab and we swapped. Its basically brand new. Its on the most recent firmware 1.27. I have downloaded the manual and read through it but this part makes no sense to me...

So here is my issue I can't figure out for the life of me is how to release out of functions that I enter. So for example since I have a parallel loop I select routing and set it to parallel and then lock it.

So here is my question how the hell do I get out of this menu and back to where I can scroll through the factory pre-sets?

This happens if I go in and set for example the Kill Dry to ON I can't get back out of this menu to the factory preset that come up when first booted
​
What ever I enter into I can't figure out for the life of me how to back out to all the Factory pre-sets.

(Side note have considered wiring the effects loop into serial...thoughts?)

My gear:
++++++++
Mesa Boogie Solo Rectifer Ser2 Amp
TC Electronics PolyTune-Dark
Boss NS-2
TC Electronics G-Major
Ibanez MTM1
Signal Chain:
++++++++
Guitar-->Tuner-->NS-2-->Amp(Pre)-->G-Major(Loop)
Any help would be great.
thanks
