So basically the issue is that it is too high of a risk and many dealers don't even want to do it anymore.
The guy that is GURU at this told me that he just changes the IMC with latest SW as it costs less and less risk is involved. So my suggestion is to be on a hunt for a scrapyard IMC and change it, programm it via SDD if it is 2016-2017 model or pathfinder if it is a later model.
