Yarns FW Update: Data is not received

#1

Hi and thanks for approval. I’m having a hard time updating yarns. When I set it to update mode (cycling 0s) and try to send the sysex file via Sysex Librarian nothing happens (also tried C6 and different timings). No data is received at all. The 0s keep cycling. Using the same midi connection in normal mode works just fine. Any ideas what I could try to make it work?

My Setup:
Emagic Unitor 8 > Midi > Yarns

Thanks in advance!
