So here's how this works out.
I get in touch with Srams help desk they talk me, well, email me, through several resets, firmware updates, trouble shootings. Etc. In the end the Derailleur is dead. Memory corruption. It's pretty common. If you look on the internet there is a growing number of bricked parts.
But, since I bought my group on ebay I am not eligible for any warranty. But what really sucks is being told to, "feel free to take it to an authorized Sram dealer for repair and maybe they can help you out " not even a crash replacement offer.
