It's such simple to do this glitch, all you need is a alt account/Friend behind the safe house. And when The Rake is coming in, make sure to not get downed or the door of the safe house will open itself.

My alt account before stopping recording, crashed because the batterie was gone even while charging it. So got mad and I completely breaked my phone, but my parent said I won't have one until Christmas. But me personnally, I don't care because the batterie was bullyshit.
