What this does, is it changes the serial checking function to accept any serial. What really happens though, is that the function checks to see if the serial matches one it can generate, and then it compares the two. If they are equal it jumps to the end of the function where it says, ‘It worked!’ By reversing the je/beq to jne/bne you set the app to accept any serial you enter, because it changes it to that the app will accept anything that it can not generate.
That’s the best explanation of what happens I can make.
