Unfortunately, I have learned a bit more since my recent attempts - I don't think you can really revert the firmware modules unless you actually have the old firmware binaries yourself (VBF files) and even then you probably need to use Forscan to do it, which is too risky even for me. FDRS appears to only move forward, for better or worse. I also have to note - I am far, far from being an expert on FDRS, flashing modules, firmware versioning etc. I would defer to someone like @benk016 for that.Cool. Thanks! If that is the case then getting a license for FDRS will be in my future. I am pretty sure I can learn how to use it. Very little risk at this point of causing more damage....
I might need it anyway since now my windows don't work so I will have to start trouble shooting what the issue could be. ???
The other potential issue would be whatever else was part of the update...I'm not 100% sure, but I think the OTA that changed the brake feel (which I and others implemented via FDRS) was the powertrain control module, and I think only the engineers at the mothership know whether anything else important was changed in that update. Even if you could revert it, ultimately your hand may be forced if/when future models depend on the PCM to be a certain version etc.
