How to downgrade controller firmware DDJ-RR ?

Hello! At once I apologize for writing, I write with the help of an interpreter. The essence of the problem is the following, there is a macbook. I decided to roll back to the old operating system. To do this, the controller firmware must be downgraded from version 1.04 to version 1.0. But the problem is that the controller can not do this in the usual way. Please tell me how to solve this problem?
