[Help] How do i corner glitch now? is it patched?

I think its patched because i cant corner glitch anymore, is there a new way?

Go to a corner. Dont crouch. instead stand while your doing it. hold shift and jump once. press w and s quickly while still holding shift. when your halfway u will see that ur in a jittery kind of state. Keep running forward. When the jittering stops crouch and move, this will make you fall down. Tadaaa!!!!

yh it is patched but you can still do it in some boxs
