Help I'm stuck in the Holon jungle

I was looking for deltas in the jungle when I got lost in the far south. I’ve tried dying in dexnav battles, reloading old saves and even cheating to get out. But nothing has worked so far. I’ve put 100 hours into this save and I really don’t want to lose it.

The only two ways that i can think to leave the Holon Jungle are:

1)Knowing the path to enter and leave

2)Having a pokemon in your party that knows the move teleport
