ROFL! Now that I actually reverse engineered the cable, the serial data transmission format, the config flash and after writing my custom flash tool, I discovered that it actually IS possible to just export the config file from the official app, edit it manually and load it back to achieve the same results! Lot's of time wasted but nevermind, who knows how the additional effort in understanding this will pay off in the future!
