Hmm, have you tried other combinations? Maybe inverting the sequence or flipping it to make sure it's oriented the right way? You should receive a scene that shows one of the stalls unlocking. If you didn't, then I'll go into the game and do some bug searchin'
I remember flipping the combination multiple times but everytime I tried going into the stall it wouldn't allow me to enter. I thought it was my computer since it heats up easily but it wasn't that, I also closed the tab but it still didn't do anything :[
