Default Winkfp HELP

Hi everybody,
I know much was written about winkfp, I've read much too, but still got some questions, really appreciate anybody could help to solve out.
As far as I know winkfp is used to update ECU, but in my situation what I need is not to update but to downgrade it from EU4 to EU2 so that I can remove after-cat O2's as well as cats themselves, I know the number of my current ECU and I know the number of ECU to which I want to downgrade. I've also imported files from sp-daten to winkfp, but what I stuck with is that I still can't understand the process entirely and want make it sure I first understand the whole process and do not get stuck when do it physically, therefore I got some questions
After selecting Comfort mode, should I select UpdateZUSB or chooseZUSB, if ChooseZUSB which ZUSB I have to choose my current ZUSB or ZUSB I'm going to downgrade to, and if it's my current ZUSB at what step I do select the ZUSB I want to downgrade to, cause I guess by default winkfp would suggest me to upgrade to newer version but what I need is older one.
Thank you.
